Session 1 of 10 · 25-Minute Module
Why This Matters
A refinery can produce fuel that meets specification and still fail to deliver value to the customer. Between its gate and the point of consumption sit nominations, pipelines, jetties, tanks, loading arms, trucks, invoices and payments, and each handover can weaken the evidence the next one needs. Over ten sessions you will build a signed Terminal Game Plan for your own business around one unresolved decision you choose today, one that currently costs your company time, money or service. AI may interpret the evidence; turning the choice into a result is leadership, which this programme trains.
25-Minute Module
0:00 – 5:00
The argument, and the finish line
THE DOCTRINE
A terminal is a system for preserving product quality, managing custody, coordinating movement and supporting commitments. Judge its intelligence by how reliably it performs those jobs.
Week 1 covers the inflection, the evidence foundation and first applications; Week 2 covers applications, trust, capital and the leadership mandate. The finish line is a signed Terminal Game Plan, the book's 90-day plan: nine sections written one per session, with the Appendix A pilot charter and Appendix B scorecard and gates completed on evidence in Session 10.
House rules: write about your own company; bring a real decision; no value claim without a baseline; no decision without a named owner; report a blocker the same day. The pass mark is 70.
Said once: this is leadership training, not legal, investment or engineering advice. The six frameworks are, in the book's words, author frameworks used across this series, not official technical standards. The templates, scorecard and gates are my proposals; a completed form does not confer technical or operating authority.
Ask which decision is waiting before you ask what to buy.
5:00 – 10:00
An illustrative Monday morning
Consider an illustrative Monday. A vessel is approaching, one tank is under inspection, two loading bays are unavailable and a customer wants urgent supply. Commercial sees an attractive sale, operations limited receiving capacity, finance an overdue account. The managing director asks for a dashboard.
The dashboard may clarify the position. It cannot authorise credit, certify a tank for service, choose a safe transfer route or change the vessel contract. Establish those responsibilities before asking a model to recommend a schedule, and record what changed after the decision.
THE DOCTRINE
A more elaborate display is valuable only when it changes a decision the operation can carry out.
AI is not required for every improvement. Reconcile a tank balance with arithmetic before anomaly detection. Establish a usable movement register before forecasting congestion. Repair a defective instrument before asking an algorithm to compensate for it.
The cheapest fix that works is a good result, not a lesser one.
What if it is wrong, late, absent or treated as authoritative?
5. Sequencing Discipline
What are the stop conditions, agreed before we start?
6. Operations-Excellence Lens
Did the recommendation reach someone who could act, and did the outcome change?
The loop fails when an alert has no owner or an action has no feedback. A supervisory acknowledgement is not evidence that the underlying stock variance was explained.
The foundation. Separate event time, when something happened, from posting time, when a system recorded it: a late-evening receipt may appear in the enterprise system next morning. An estimate must not acquire the status of an approved measurement because it fills a gap.
THE DOCTRINE
Each step up the Autonomy Ladder requires a separate permission decision. Permission to identify an inventory discrepancy does not permit writing down stock.
Map, sequence and lens. A weak cash case should not hide inside a safety narrative. Test cases where the system should decline to recommend. A precise forecast delivered after the decision may have little value.
PRODUCT AND MOVEMENT · THE WORKED CASE
Product and movement. In a fictional coastal marine terminal: will a shore tank be ready for a receipt? The gauge senses, the planner decides, an authorised operator acts. The loop breaks at learn if the movement record is never reconciled.
OWNERSHIP AND VALUE · THE PARALLEL
Ownership and value. The same receipt commercially: whose entitlement it adds to, whether credit is approved for the onward sale, whether the invoice closes. It breaks at act if nobody on shift can approve credit. One decision, seen twice.
Find the broken stage before you price the clever one.
18:00 – 23:00
Four records to reconcile, and the legal foundation
Ledger
What it describes
A disagreement the book names
Physical
Stock and movements
A tank can be full while the operator owns little of its contents
Ownership
Entitlement, commitments and restrictions
Product can be owned while it is unavailable for dispatch
Movement
Authorisation, execution and handovers
A delivery can be complete while its invoice is disputed
Financial
Value, liabilities, invoices and receipts
A sale can be profitable while the cash needed to execute it is unavailable
These four ledgers are the programme's language; Session 3 teaches them in depth. Link them through controlled movement identifiers. When they disagree, record the issue, evidence version, responsible person, next action and review date.
THE DOCTRINE
When the four views disagree, the disagreement becomes a managed exception. It remains visible until a responsible person resolves it with evidence.
Nigeria's Petroleum Industry Act establishes distinct institutions for upstream and for midstream and downstream regulation. Map the requirements applicable to your own activities, not to the word terminal. The Act is a legal foundation, not a substitute for a current facility compliance register [1].
The archetypes: coastal marine terminal, road-fed inland depot, refinery-connected facility, third-party tank farm. Say which yours resembles. Where a chapter covers an activity you do not run, apply it to the nearest equivalent decision, or to the counterpart you depend on.
Four records that agree are worth more than one record that looks confident.
23:00 – 25:00
Write it down, and Section 1
Before you close the laptop, write one sentence naming your decision as the book asks: the product, the facility, the customer commitment and the review date. Then write one sentence on the evidence that is missing.
Choose a decision that costs time, money or service now, not one that sounds like an AI project.
Section 1 of your plan is Our company, its terminal archetype, the one decision we will carry, and where its loop breaks.
The decision you choose today is the one you will sign for in Session 10.
Key Terms
Operating-Intelligence Loop
Sense, decide, act and learn, drawn around one decision with its information source, decision owner, action route and result record.
Four ledgers
Physical, ownership, movement and financial records of the same business, linked through controlled movement identifiers. Related records, not interchangeable measures.
Event time and posting time
When something physically happened, and when a system recorded it. Two reports at different cut-offs can disagree while describing the same operation.
Autonomy Ladder
Explain, recommend, prepare an action for approval, perform a narrowly authorised administrative action. Each step requires a separate permission decision.
Self-Check — Before You Submit
1. A fictional inland depot is offered an anomaly-detection tool, but its daily tank balances have never been reconciled with arithmetic. What comes first?
A. Buy the tool, since it will find what arithmetic misses
B. Reconcile the tank balance with arithmetic, then decide whether anomaly detection is still needed
C. Ask the vendor for a higher accuracy figure
D. Let the tool write down stock automatically to save time
B. Reconcile the tank balance with arithmetic, then decide whether anomaly detection is still needed — Reconcile a tank balance with arithmetic before introducing anomaly detection. A vendor accuracy figure is tempting, but it says nothing about a balance nobody has reconciled.
2. On the illustrative Monday morning, which of these can the dashboard do?
A. Authorise credit for the urgent customer
B. Certify the inspected tank for service
C. Change the vessel contract
D. Clarify the position for the people who must decide
D. Clarify the position for the people who must decide — The dashboard may clarify the position. It cannot authorise credit, certify a tank, choose a safe transfer route or change the vessel contract; those responsibilities sit with people.
3. An application may identify inventory discrepancies. A manager wants it to post the write-downs too. What is right?
A. Posting needs its own permission decision, with a named owner, tested limit and recovery route
B. It may post them, since it found them
C. It may post them if its confidence is high
D. It may post them if finance is copied
A. Posting needs its own permission decision, with a named owner, tested limit and recovery route — Each step requires a separate permission decision. Permission to identify a discrepancy does not permit writing down stock. High confidence is the tempting answer, but confidence is not authority.
Today’s Assignment
Name your company, its operating archetype and the one unresolved decision you will carry through this programme, and show where its Operating-Intelligence Loop breaks.
Your company. Its name, what it does, and which archetype it most resembles, with a reason.
The decision. One unresolved decision that costs your business time, money or service, stated as the book asks: the product, the facility, the customer commitment and the review date.
The missing evidence. What you do not have today, and which ledger it belongs to.
The loop. Draw it around that single decision: information source, decision owner (a role, not a department), action route and result record. Name the stage where it breaks and why.
The simpler alternative. Whether arithmetic, a usable register or a repaired instrument comes before any model.
The honest part. What your company gets wrong about this decision today. No AI in use yet is normal: work from the decision in front of you.
Four hundred to nine hundred words.

From Product to Value: The Intelligent Terminal Company
Session 2 of 10 · 25-Minute Module
Why This Matters
Throughput is attractive because it is easy to count. It is also incomplete. A terminal may move more litres while earning less contribution, carrying more disputed inventory or lending more money through unpaid invoices. This session connects each movement in your decision with its commercial purpose, then examines the operating model underneath it. If that model is unclear in your company, no software will make it clear. You will leave with a value map and a named review that owns your decision.
25-Minute Module
0:00 – 6:00
Throughput is incomplete
Ask what each movement was for. Did the business earn a handling fee, complete a product sale, satisfy a storage agreement or support an internal distribution requirement? The same physical movement can have different economics under different contracts.
A product owner may benefit from faster sale, while a storage provider earns mainly from occupancy and handling. Value can disappear as missing product, downgraded quality, idle capacity, avoidable delay, unbilled service or unpaid debt. Each requires a different investigation.
THE DOCTRINE
A stock variance is not automatically theft. A demurrage invoice is not automatically avoidable. A late delivery is not automatically a transport failure.
Allocate an exception to an event and a responsible interface. A statement that logistics is expensive supports no investment decision. A record showing that three dispatches failed because customer storage was unavailable can support changes to order confirmation, transport allocation and receiving readiness.
Count litres, but report what they earned and what they are still owed.
6:00 – 12:00
The value map and the value case
Build the value map around the actual supply route. A coastal receipt followed by road distribution has different handovers from a pipeline-fed depot serving nearby industrial customers. Include power, access or third-party constraints, and do not describe all Nigerian terminals through one average. Map where product enters, how it is measured, where it can be held, which routes are available and who accepts it at the destination. Show both the physical route and the points where responsibility changes.
Contribution, in plain words, is what additional business leaves after the costs that rise with it. It is not revenue. The book's value case is illustrative:
Where AI helps: ask which movements are most likely to miss tomorrow's customer commitment. The answer should show the cause, confidence, available action and decision deadline. An executive still chooses among obligations and approves the response.
Illustrative input
Value
Annual throughput (assumed)
60 million litres
Incremental contribution on eligible additional business (assumed)
₦8 per litre
Genuinely additional litres from better coordination
2 million litres
Contribution before programme costs (2 million × ₦8)
₦16 million
This is an illustrative calculation, not an industry benchmark. It is valid only if demand exists, contribution excludes variable handling costs and volume is incremental. Finance should test those distinctions before accepting the benefit.
PRODUCT AND MOVEMENT · THE WORKED CASE
Product and movement. In a fictional road-fed inland depot, a truck is loaded but the customer's storage is unavailable on arrival. The physical failure sits at the receiving interface, not in transport.
OWNERSHIP AND VALUE · THE PARALLEL
Ownership and value. Without an accepted delivery, the financial ledger has no completed movement to support an invoice. Moving the order from Tuesday to Monday next time improves service but may not increase annual sales. One event, two ledgers.
Ask finance to test whether the volume is truly additional before anyone celebrates it.
12:00 – 18:00
Operating model before software model
Sales has orders, operations a tank sheet, maintenance equipment restrictions and finance exposure. The company becomes intelligent when those boundaries meet in a shared decision, with agreed definitions of available product, usable capacity and an authorised movement.
An independent storage operator earns differently from a marketer that owns and distributes product. A third-party terminal can hold product for several owners at once. So define the operating model first: who owns product, bears loss, nominates movement and pays for delay? Written agreements should answer those questions.
THE DOCTRINE
An algorithm cannot resolve an ambiguous entitlement by selecting the most convenient interpretation.
Informal intervention creates hidden commitments: a loading slot promised without checking release status, credit given through an operational favour, maintenance postponed because the dispatch plan never included the outage. Establish a visible exception process with limits, approvers and expiry dates.
The architecture sequence: keep authoritative records in controlled systems; draw validated data into an operating view; apply forecasting or optimisation to that view; return approved instructions through a documented interface; retain the version used for the decision. The NIST AI Risk Management Framework organises risk activities around govern, map, measure and manage. It is voluntary, and it does not certify that a particular terminal application is safe or suitable [2].
If the contract is ambiguous, fix the contract; the model will only choose a side.
18:00 – 23:00
The meeting rhythm and the first pilot
Meeting
What it addresses
Shift
Physical readiness and active exceptions
Daily review
Receipts, dispatches and commitments
Weekly
Recurring causes and resource decisions
Monthly review
Economics and control
Each meeting inherits unresolved actions from the last. The terminal manager owns response, commercial validates commitments, finance approves credit and confirms benefits, digital specialists maintain the system.
The book's first pilot is the next-day operating review at one facility, with a fixed cut-off and a controlled change log. Participants approve a movement plan and identify unresolved conditions. Acknowledging a presentation is not equivalent to approving an action.
Record every change after the review: customer revision, equipment fault, late receipt or executive override. That establishes whether the plan was weak or the situation changed. Also record concerns raised where no action was possible: a better forecast cannot create a missing customer tank or an unfunded transport order.
THE DOCTRINE
If every movement still requires a private call to the owner, the digital programme has not yet changed the operating model.
For the board: contribution, commitments met, unresolved claims and cash tied to completed movements, explained alongside throughput; and plan stability, failed handovers, overdue decisions and exceptions operating beyond their approval period, including a conflict resolved with evidence.
An override recorded is a lesson; an override remembered is a habit.
23:00 – 25:00
Write it down, and Section 2
Before you close the laptop, write the one handover in your decision where responsibility changes and nobody is quite sure who holds it.
Then write which meeting in your current rhythm should own the decision. If the honest answer is a private call, say so.
Section 2 of your plan is The value map for our decision, the operating model behind it and the review that will own it.
A value map that shows no change of responsibility has not yet been drawn honestly.
Key Terms
Contribution
What additional business leaves after the costs that vary with it. The book's value case requires contribution to exclude variable handling costs; it is not revenue or throughput.
Value map
The actual supply route for a decision: where product enters, is measured, held, moved and accepted, and the points where responsibility changes.
Operating model
The written answer to who owns product, bears loss, nominates movement and pays for delay. It is defined before the software model.
Visible exception process
A documented route for departures from the plan, with limits, approvers and expiry dates, so the business can learn what an exception cost and whether it should recur.
Self-Check — Before You Submit
1. A fictional depot claims 2 million litres as additional contribution from a coordination tool. Most are existing orders moved earlier in the week. What should finance conclude?
A. Accept the claim, since the litres moved
B. Accept half the claim as a compromise
C. The benefit is not established: moving an order earlier improves service but may not increase annual sales
D. Double the claim to include handling fees
C. The benefit is not established: moving an order earlier improves service but may not increase annual sales — The case is valid only if demand exists, contribution excludes variable handling costs and volume is incremental. Moving an order from Tuesday to Monday improves service without adding sales. A compromise figure has no evidence behind it either.
2. Which is the book's first question about the operating model?
A. Who owns product, bears loss, nominates movement and pays for delay
B. Which dashboard vendor to choose
C. How many users need licences
D. Which model is most accurate
A. Who owns product, bears loss, nominates movement and pays for delay — Define the operating model before the software model. Written agreements should answer those four questions; an algorithm cannot resolve an ambiguous entitlement. Choosing a vendor first is the common trap.
3. At a next-day operating review, every manager acknowledges the presentation and the meeting closes. What has the review failed to produce?
A. A longer presentation
B. An approved movement plan with unresolved conditions identified
C. A higher forecast accuracy
D. A new dashboard
B. An approved movement plan with unresolved conditions identified — Acknowledging a presentation is not equivalent to approving an action. The pilot asks participants to approve a movement plan and identify unresolved conditions, with a fixed cut-off and a controlled change log.
Today’s Assignment
Map the value route for your decision, answer the four operating-model questions and name the review that will own it.
The value map. For your Session 1 decision, show where product enters your business, how it is measured, where it is held, how it moves and who accepts it. Mark every point where responsibility changes.
Where value is lost. Name the form of loss (missing product, downgraded quality, idle capacity, avoidable delay, unbilled service or unpaid debt), allocate it to an event and a responsible interface, and say what it is not automatically.
The operating model. Answer the four questions for your decision: who owns product, bears loss, nominates movement and pays for delay. Say where the written agreement is silent or ambiguous.
Hidden commitments. One informal intervention your company makes today, and the limit, approver and expiry date that would make it visible.
The rhythm. Which meeting (shift, daily, weekly or monthly) will own the decision, who attends by role, and how changes after the review will be recorded.

Capabilities Covered
Connecting movement to commercial purposeMapping the value routeTesting an additional-volume claimOperating model before softwareRunning the meeting rhythm
A level reading does not tell you everything needed to sell or move product. Volume depends on how it was measured and on what basis. Availability depends on operating condition, quality release, entitlement and existing commitments. Two records of the same stock can disagree for reasons that have nothing to do with theft or loss: a timing error can change the stock record without changing the physical product. This session gives you the evidence foundation and the four ledgers in depth. You will leave able to ask a measurement or finance team the right questions about a residual.
25-Minute Module
0:00 – 6:00
Identity first
The evidence foundation begins with identity: which tank, product, batch, owner and measurement event does this record describe? Without that, a model can join unrelated observations and produce a convincing error.
One tank may appear under several names; a replaced instrument may keep its predecessor's identifier; a product code may mean different things in the laboratory and the sales system.
THE DOCTRINE
These are operating weaknesses before they are AI weaknesses. The newest display does not necessarily carry the most dependable value.
Facilities may combine manual records, automatic gauges, loading presets, laboratory certificates and enterprise software. The practical task is to establish how each record becomes authoritative. A depot with limited instrumentation can begin with controlled manual evidence and systematic reconciliation; an instrumented terminal may first need to correct clocks, tag names and interfaces.
Before you ask what the number is, ask what the number is about.
6:00 – 12:00
What a measurement must carry
For a tank measurement, record time, liquid level, relevant temperature and density evidence, water determination, calibration-table version, method and operator or instrument identity. Apply the approved method for the facility and product.
Observed volume is what was measured under the conditions at the time. A corrected volume restates it on an agreed reference basis so that measurements can be compared. Do not mix the two without explicitly identifying the conversion; otherwise a difference may be arithmetic, not product.
The API petroleum measurement catalogue covers disciplines including gauging, temperature, sampling, density, quantity calculation and marine measurement. The applicable standards and approved editions belong in the controlled technical register. A catalogue does not itself establish a site's measurement procedure [3].
THE DOCTRINE
Preserve raw observations and corrected values separately. An estimate may help planning while remaining unsuitable for custody or financial posting.
A correction states its reason, authority and version; an implausible reading is investigated, not silently replaced with a model estimate. Use deterministic rules for missing identifiers, stale gauges, duplicate tickets and unclosed transfers; statistical methods help where history supports harder pattern recognition. Distinguish geometric tank capacity from capacity available under the approved operating envelope.
The pilot follows two tanks of one product through a daily balance, with a measurement specialist reproducing selected balances from original records. Counting records imported measures activity; reproducibility measures whether the foundation is usable. Then assign master-data owners and teach shift staff the authorised fallback source during an interface failure.
If your team cannot reproduce yesterday's balance, the model will not reproduce it either.
12:00 – 19:00
The four ledgers and the worked example
Inventory accuracy is a relationship between a physical quantity and a controlled record at an agreed boundary, cut-off and basis. The four ledgers need four explicit views with controlled links and clear ownership, not four new software products.
The physical-ledger equation. Expected closing stock equals opening stock plus receipts and transfers in, less dispatches and transfers out, with signed approved adjustments. The residual is measured closing stock less expected closing stock: the part the arithmetic cannot yet explain. The book's example is illustrative, all on the same approved basis:
Line
Litres or value
Opening stock
10,000,000
Plus receipts
4,000,000
Less dispatches
3,500,000
Expected closing stock (no adjustments or net boundary transfer)
10,500,000
Measured closing stock
10,470,000
Residual
negative 30,000
Magnitude
0.75% of receipts, or approximately 0.286% of expected closing stock
Apparent exposure at an assumed ₦900 per litre
₦27 million
The denominator is what you divide the residual by to express it as a percentage. Neither denominator is universally correct. Report the one chosen and use it consistently.
THE DOCTRINE
The ₦27 million is an investigation estimate. It is not proof that ₦27 million was stolen, recoverable or permanently lost. A timing error can change the stock record without changing the physical product.
PRODUCT AND MOVEMENT · THE WORKED CASE
Product and movement. For the residual above, ask whether internal transfers were complete on both sides, whether line contents or changes in line fill were included, and whether a late posting moved a dispatch across the cut-off. The movement ledger shows each transfer's status.
OWNERSHIP AND VALUE · THE PARALLEL
Ownership and value. The ownership ledger allocates the same stock to approved entitlements, distinguishing owned inventory from product held in custody and keeping pledged or restricted stock visible to finance and commercial staff. Finance links the same movements to valuation, fees, invoices, claims and receipts, and a balance can reconcile while a service remains unbilled.
Always ask which denominator, and always ask why that one.
19:00 – 23:00
What AI may do, and who approves
A model can rank residuals by value, persistence, evidence quality and similarity to resolved cases, showing the movement records and competing explanations.
THE DOCTRINE
A probability label must not become a stock adjustment or an allegation.
The pilot reconciles one product daily across all four views with a controlled exception register. Sample apparently clean balances as well as flagged ones; otherwise missed errors remain invisible.
Finance approves valuation and posting adjustments. Measurement specialists approve the technical basis. The terminal manager ensures a closed investigation has evidence, an authorised correction where needed and a preventive action where appropriate.
For the board: gross unresolved residuals, their age and cause status. Do not net unrelated positive and negative differences to create a reassuring average. Report confirmed physical loss separately from accounting corrections, ownership disputes and timing effects.
A reassuring average is often two problems cancelling each other out.
23:00 – 25:00
Write it down, Section 3, and Pop Quiz 1
Before you close the laptop, write one place in your company where two records of the same thing disagree today, and whether the cause is more likely identity, basis or timing.
Section 3 of your plan is The evidence our decision needs and the four ledgers that must reconcile around it.
Pop Quiz 1 opens now: five questions, closed book, on Sessions 1 to 3. Sit it before you start Session 4.
Disagreement between records is information; hiding it is the failure.
Key Terms
Residual
Measured closing stock less expected closing stock for a defined boundary, period and basis. An unexplained residual is not an approved operating loss.
Observed and corrected volume
The volume measured under the conditions at the time, and the same quantity restated on an agreed reference basis. They are never mixed without identifying the conversion.
Ownership ledger
Stock allocated to approved entitlements, commitments and restrictions, distinguishing owned inventory from product held in custody and keeping pledged stock visible.
Deterministic rule
A fixed, stated check, such as for missing identifiers, stale gauges, duplicate tickets or unclosed transfers, applied before statistical methods.
Self-Check — Before You Submit
1. In the book's illustrative example, the residual is negative 30,000 litres. Which statement is correct?
A. The residual is 0.75% of expected closing stock
B. The ₦27 million exposure proves product was stolen
C. It is 0.75% of receipts or approximately 0.286% of expected closing stock, and the chosen denominator must be reported
D. The residual can be netted against a positive difference elsewhere
C. It is 0.75% of receipts or approximately 0.286% of expected closing stock, and the chosen denominator must be reported — Thirty thousand litres is 0.75% of 4,000,000 litres of receipts and about 0.286% of 10,500,000 litres of expected closing stock. Neither denominator is universally correct, and the ₦27 million is an investigation estimate.
2. A fictional terminal's model flags a residual on one shift with a high probability of loss. The operations director wants to adjust the stock record and question the shift team. What should happen?
A. Adjust the stock and question the team, since the probability is high
B. Treat the flag as a priority for investigation, show the movement records and competing explanations, and leave adjustments to the approved route
C. Ignore the flag, since models are unreliable
D. Net the residual against last month's gain
B. Treat the flag as a priority for investigation, show the movement records and competing explanations, and leave adjustments to the approved route — A probability label must not become a stock adjustment or an allegation. Finance approves valuation and posting adjustments; measurement specialists approve the technical basis. Ignoring the flag is the opposite error and hides exposure.
3. An overnight interface delivers yesterday's dispatch after the morning report closes. How should the receiving system treat it?
A. As a completeness issue, recalculating affected balances through an approved process
B. As a loss on yesterday's balance
C. By overwriting the event time with the arrival time
D. By substituting a model estimate
A. As a completeness issue, recalculating affected balances through an approved process — Retain event time and arrival time. The book says the receiving system should identify the delay as a completeness issue and recalculate affected balances through an approved process. Overwriting the event time destroys the evidence.
Today’s Assignment
Set out the evidence your decision needs and the four ledgers that must reconcile around it.
The evidence. For your Session 1 decision, list what each key record must carry: identity (tank, product, batch, owner, measurement event), measurement basis, event time and posting time, and status.
One disagreement. Name one place in your company where two records of the same thing disagree today. Say whether identity, basis, timing or something else is the likely cause, without presuming loss or fault.
The four ledgers. For your decision, state what each ledger records, who owns it by role, how the four are linked (which movement identifier) and who approves a correction.
The residual. How your business currently reports stock differences: which denominator, whether gross or netted, and whether timing effects are separated from confirmed loss.
The honest part. Which record your company treats as authoritative only because it is newest or most visible.
Four hundred to nine hundred words.

Parts Two and Three · Custody and ExceptionsSESSION 4
Custody Transfer, Commercial Trust and Exception Investigation
Session 4 of 10 · 25-Minute Module
Why This Matters
Custody transfer is where an operating measurement becomes a commercial fact. If the record of that moment is weak, your company can run an efficient terminal and still lose trust and delay invoices. When a difference appears, the way your business investigates it says a great deal about its culture. Calling every variance theft creates noise and discourages reporting; calling every variance acceptable loss hides exposure. This session covers both: the evidence that makes a handover defensible, and an investigation route that tests explanations while protecting evidence and treating people fairly.
25-Minute Module
0:00 – 6:00
Where a measurement becomes a commercial fact
At custody transfer, responsibility for product passes from one party to another, and the quantity recorded there becomes what is invoiced, accepted or disputed. Quantity, quality, timing and responsibility must be supported by evidence accepted under the relevant agreement.
A receipt may move from vessel to shore tank, pipeline to depot or truck to customer storage; a dispatch may pass through independent inspection, carrier acceptance and customer acknowledgement. Each interface can use a different record and cut-off.
Map the accepted measurement point, quantity basis, sampling arrangements, signatories and dispute process for the actual contract. Several measurements of one movement are not necessarily comparable: differences may reflect basis, boundary, timing, line contents or uncertainty.
THE DOCTRINE
AI can help assemble and examine the custody record. It should not decide contractual interpretation, certify measurement or approve a claim merely because a document looks complete.
Ask which measurement the contract accepts before you ask which measurement is right.
6:00 – 12:00
Presence is not validity
Value is lost through missing signatures, inconsistent identifiers, unrecorded meter events and unsupported amendments. Treat document completeness as an operating control.
Link the nomination, movement instruction, measurement and quality evidence, relevant inspection record, ticket and acceptance record. Capture who signed, when, what quantity they accepted and any reservation. A laboratory certificate may exist but refer to another batch; a signed ticket may carry a different movement identifier. A completeness score should test relationships, not count attachments.
Document extraction can prepare a custody-pack checklist, flag mismatched dates, product codes, quantity bases or signatures, and compare a draft invoice with the movement record. Keep every important extracted value linked to its source. Confidence determines review priority; it does not replace review. Handwriting, poor scans and ambiguous units become explicit unresolved fields, not plausible guesses.
The book's value case is illustrative: custody-document defects delay ₦200 million of otherwise valid invoices by three days. The value is a shorter exposure if defects are corrected sooner. It is not an additional ₦200 million of revenue, and any financing benefit depends on the actual funding arrangement and collection behaviour.
PRODUCT AND MOVEMENT · THE WORKED CASE
Product and movement. In a fictional inland depot, a truck dispatch carries a loading ticket with the movement identifier, quantity basis and signatures. The customer measures at its own tank on a different basis, so the quantities are not directly comparable.
OWNERSHIP AND VALUE · THE PARALLEL
Ownership and value. The customer signs acceptance with a reservation. The invoice waits for the custody pack, and the receivable sits exposed for longer. Correcting the pack sooner shortens that exposure; it creates no new revenue.
A complete-looking file is a claim; a matched file is evidence.
12:00 – 19:00
An exception is not a verdict
A difference may reflect timing, measurement, product condition, line contents, record error or actual loss. Value is lost when exceptions stay open without owners, when causes are corrected administratively but not operationally, and when a small recurring difference is overlooked.
Classify exceptions by magnitude, persistence, product, boundary and evidence status, and keep that classification separate from the final cause. A high-priority event may later prove to be a posting error; its priority was still justified by what was known.
Investigation step
What a leader asks
Freeze the relevant evidence version
Which version are we examining?
Confirm boundary, period and measurement basis
Are we comparing like with like?
Reconstruct movements and test posting and reversal history
Did the record change, or the product?
Review instrument and product-condition evidence with competent specialists
Who is qualified to judge this?
Record competing explanations and the evidence to distinguish them
What would tell them apart?
Preserve authorised access and chain of custody where records may support a claim or formal inquiry. Pattern analysis can group similar events and prioritise cases; evaluate it against investigation outcomes, including missed confirmed events and cases correctly left unflagged, not the number of alerts.
THE DOCTRINE
Establish facts before assigning responsibility. An AI-generated narrative is a draft analysis, not a witness account or a finding of misconduct.
Write down the competing explanations before anyone falls in love with one.
19:00 – 23:00
The loss arithmetic and the pilot
A percentage point is a change in a rate itself: a fall of 0.05 percentage points means the share of throughput lost is five hundredths of one per cent of throughput lower. The book's example is illustrative: 80 million litres of annual eligible throughput, an independently supported 0.05 percentage-point reduction in confirmed avoidable physical loss, 40,000 litres, at an assumed ₦850 per litre, gives ₦34 million gross before investigation, maintenance and programme costs. It requires a comparable boundary and basis, a supported baseline and evidence that actual loss changed.
THE DOCTRINE
A reduction in unexplained residuals caused by better posting is reconciliation improvement. It must not also be claimed as product recovered.
The pilot: one product, a bounded set of movements, agreed priority rules and investigation capacity, historical resolved cases first and then prospective operation with human review. Compare effort with confirmed outcomes, and test whether staff can explain the ranking from evidence rather than accept a score they cannot examine.
For the board: confirmed loss separately from unresolved exposure, accounting corrections and measurement issues, and recurrence after corrective action. A closed exception without a cause or an approved basis for closure stays visible as an incomplete investigation.
Count the benefit once, under the name that matches its evidence.
23:00 – 25:00
Write it down, and Section 4
Before you close the laptop, write the custody interface your decision depends on and the one document relationship most likely to fail there.
Then write the exception type you will route, and who in your company currently closes it, and on what evidence.
Section 4 of your plan is Our custody evidence and the route by which an exception becomes a supported finding. The executive standard: your business can show what was transferred, on which basis, under whose authority and with which acceptance.
Fairness in investigation is a control, not a courtesy.
Key Terms
Custody transfer
The handover at which an operating measurement becomes a commercial fact, supported by quantity, quality, timing and responsibility evidence accepted under the relevant agreement.
Custody pack
The linked record of a handover: nomination, movement instruction, measurement and quality evidence, inspection record, ticket and acceptance, with signatures, times, accepted quantities and reservations.
Exception
An invitation to investigate, not a verdict. Its priority classification is kept separate from its final cause.
Reconciliation improvement
A reduction in unexplained residuals caused by better records or posting. Reported separately from, and never also claimed as, product recovered.
Self-Check — Before You Submit
1. A fictional terminal's investigation tool produces a fluent narrative naming a loading supervisor as the likely cause of a difference. The managing director wants to start disciplinary action. What should happen?
A. Start disciplinary action, since the narrative is detailed
B. Treat the narrative as a draft analysis, freeze the evidence, test competing explanations with competent specialists and establish facts before assigning responsibility
C. Delete the narrative to avoid embarrassment
D. Close the exception as acceptable operating loss
B. Treat the narrative as a draft analysis, freeze the evidence, test competing explanations with competent specialists and establish facts before assigning responsibility — An AI-generated narrative is a draft analysis, not a witness account or a finding of misconduct. Facts come before responsibility. Closing it as acceptable loss is the opposite error: it hides exposure instead of investigating.
2. Custody-document defects delay ₦200 million of valid invoices by three days. What is the value of fixing them, as the book states it?
A. ₦200 million of additional revenue
B. ₦600 million, three days at ₦200 million
C. A guaranteed financing saving
D. A shorter duration of exposure, with any financing benefit depending on the funding arrangement and collection behaviour
D. A shorter duration of exposure, with any financing benefit depending on the funding arrangement and collection behaviour — The immediate value is a reduction in the duration of the exposure. It is not additional revenue. Multiplying by days is a tempting but meaningless calculation, and a financing benefit depends on actual arrangements.
3. Better posting removes many unexplained residuals at a fictional depot, and the programme team wants to report the litres as product recovered. What is right?
A. Report it as reconciliation improvement, not as product recovered
B. Report it as product recovered, since the residuals fell
C. Report both, since both are true
D. Report neither
A. Report it as reconciliation improvement, not as product recovered — A reduction in unexplained residuals caused by better posting is reconciliation improvement. Claiming the same litres as recovered product double counts the benefit and misstates what physically changed.
Today’s Assignment
Map one custody interface your decision depends on, and write the investigation route for one exception type.
The custody interface. For your Session 1 decision, name the handover and set out the accepted measurement point, quantity basis, sampling arrangements, signatories, dispute route and the evidence invoicing needs. If your business uses a third-party tank farm or depends on a counterpart, map that counterpart's interface.
Presence versus validity. One document relationship in your company that could be present but invalid, and how you would test it.
The exception route. For one exception type: priority rules, the evidence frozen, the competing explanations, who investigates by role, and who approves closure on what evidence.
Fairness. How your route keeps a flag or a narrative from becoming an allegation against a person.
The honest part. How your company actually treats variances today: as theft, as acceptable loss, or somewhere between.

Why This Matters
A commercially attractive receipt can consume the only flexibility your operation had for another commitment. A vessel's arrival triggers a chain of dependent decisions, and a terminal can speed up one stage while delaying the next. This session teaches you to separate confirmed constraints from forecasts, engineering limits from commercial preferences, and a forecast from a contractual fact. If your business has no jetty, the same discipline applies to the supplying facility, the trucks or the counterpart you wait for. You will leave with a readiness plan whose handovers have names on them.
25-Minute Module
0:00 – 6:00
Usable space is not empty space
Available space depends on tank restrictions, product compatibility, quality release and receiving preparation. Shared pumps and lines can limit movement even when tank space exists. A marine-fed tank farm may need to prepare for uncertain vessel arrival while maintaining road dispatch; an inland depot may depend on the availability of a supplying facility and transport.
Maintain tank status, approved operating limits, product and quality status, expected receipts, dispatch commitments, transfer routes and resource constraints. Distinguish confirmed events from forecasts, and record preparation time and the approvals required before a tank or route becomes available.
THE DOCTRINE
An engineering or safety limit is different from a commercial preference. The model must not relax the former to improve its objective. A commercial preference may be changed by an authorised person, with the consequence recorded.
Staff who operate the tanks and routes review whether the plan respects shared resources. An optimiser should make a trade-off visible, not hide it inside a recommended sequence.
Ask which constraints the plan bent, and who signed for bending them.
6:00 – 12:00
Three cases and the first binding constraint
Ask the system for a base plan, a delay case and a disruption case. Then identify the first binding constraint, the first limit that stops the plan working as conditions change, and the decision needed to respond.
The book's scheduling example is illustrative:
Illustrative input
Litres
Expected receipt
3 million
Approved usable space, compatible tank 1
1.8 million
Approved usable space, compatible tank 2
1.5 million
Together (1.8 + 1.5), a screening result only
3.3 million
If tank 2 remains on inspection hold
The nominal 3.3 million is not available
That arithmetic does not establish that the transfer is safe or feasible. The operator must verify actual tank and route status, operating limits, measurement basis and receiving arrangement. A forecast of dispatch before vessel arrival may create space in a scenario while leaving the confirmed receiving plan unresolved.
THE DOCTRINE
A single apparently optimal answer can conceal fragility to a small change in arrival or dispatch.
The pilot runs in parallel with existing planning for one product, testing a delayed vessel, an unavailable pump and collection below forecast. A plan that requires undocumented overrides is not a successful optimisation. In operation, record override reasons, approvers and expiry.
Screening arithmetic opens a question; it never closes one.
12:00 – 18:00
The ship and shore interface
A vessel's arrival creates dependent decisions: berth readiness, shore receiving capacity, product acceptance, personnel availability, transfer arrangements and departure readiness.
An estimated time of arrival is a forecast: a best current view that can move. A notice, a readiness confirmation and a contractual time event are different records. AI should help staff distinguish and relate them. It must not turn an inferred timestamp into a contractual fact.
The International Safety Guide for Oil Tankers and Terminals addresses the tanker and terminal interface. It is a relevant reference for competent personnel and controlled operating arrangements. A scheduling application does not replace the applicable ship and shore procedures [4].
Map responsibilities across the vessel, terminal, agent, surveyor and other required parties, before arrival, berthing, transfer and completion. Keep unresolved conditions visible rather than translating them into an optimistic readiness score.
Preserve the source of each timestamp; an email receipt time may differ from the time of the event it describes. A model can flag inconsistencies; a competent authorised person decides the contractual treatment. If your business is an inland depot, the book says it may begin with dispatch and replenishment: apply this to the supply arrivals you depend on.
Every timestamp should be able to say where it came from.
18:00 – 23:00
Delay, its cause and its counterfactual
Delay can originate in berth congestion, inadequate receiving capacity, product documentation, equipment unavailability or a change in the commercial plan. A demurrage bill alone does not identify the avoidable cause. Separate terminal-controlled from external delay and test the classification against evidence.
The counterfactual is what would have happened without the intervention. The book's example is illustrative: a contractual charge of US$24,000 per day applies to a particular avoidable period; avoiding 18 eligible hours gives US$18,000 gross (18/24 of a day); a response costing US$3,000 leaves US$15,000 net. It depends on the actual contract, eligible time and supported counterfactual. It is not established by multiplying every hour in port by a daily rate.
PRODUCT AND MOVEMENT · THE WORKED CASE
Product and movement. In a fictional coastal marine terminal, an arrival-readiness brief lists confirmed conditions, forecast ranges, unresolved dependencies and named actions. The tank is prepared before the decision deadline.
OWNERSHIP AND VALUE · THE PARALLEL
Ownership and value. The same call seen commercially: only eligible hours under the actual contract count, and if another unavoidable constraint would have prevented earlier completion, the claimed saving may not be real.
Measure forecast usefulness at the decision deadline. A later accurate arrival prediction does not recover a missed opportunity to prepare a tank or arrange personnel. For the board: berth waiting and transfer time by supported cause, claim status and interventions with verified value.
Value a saving against what would really have happened, not against the worst case.
23:00 – 25:00
Write it down, Section 5, and Practice Exam 1
Before you close the laptop, write the first constraint that would bind in your decision's delay case, and whether it is an engineering or safety limit or a commercial preference.
Section 5 of your plan is Our schedule and readiness plan: confirmed constraints, forecast ranges and accountable handovers.
Practice Exam 1 opens now: fifteen questions on Sessions 1 to 5, closing Week 1. Sit it before you start Session 6; it may be resat as often as you like.
Readiness is a list of handovers with names, not a percentage.
Key Terms
Approved usable space
Tank capacity actually available under the approved operating envelope, after restrictions, compatibility, quality release and receiving preparation. Not geometric capacity.
First binding constraint
The first limit that stops a plan working as arrival or dispatch conditions change, identified across the base, delay and disruption cases.
Contractual time event
A record with contractual consequence, distinct from an estimated time of arrival, a notice or a readiness confirmation. Its treatment is decided by a competent authorised person.
Counterfactual
What would have happened without the intervention. A claimed saving must be measured against it, using eligible time under the actual contract.
Self-Check — Before You Submit
1. A fictional terminal's optimiser proposes receiving a profitable cargo by filling a tank above its approved operating limit for a few hours. The commercial director supports it. What is right?
A. Accept it, since the commercial director has authority
B. Accept it if the model's confidence is high
C. Reject it: an engineering or safety limit is not a commercial preference, and the model must not relax it
D. Accept it and record the consequence afterwards
C. Reject it: an engineering or safety limit is not a commercial preference, and the model must not relax it — An engineering or safety limit is not a commercial preference, and the model must not relax it to improve its objective. Only a commercial preference may be changed by an authorised person, with the consequence recorded.
2. In the illustrative scheduling example, two compatible tanks show 1.8 and 1.5 million litres of approved usable space for a 3 million litre receipt. What does the 3.3 million total establish?
A. A screening result only, to be verified against tank and route status, limits, basis and receiving arrangement
B. That the transfer is safe and feasible
C. That 300,000 litres of spare capacity can be sold
D. That the inspection hold can be ignored
A. A screening result only, to be verified against tank and route status, limits, basis and receiving arrangement — The arithmetic is only a screening result. If the second tank remains on inspection hold, the nominal 3.3 million litres is not available. Selling the apparent surplus is the tempting error.
3. A vessel spent three days in port at a fictional terminal under a contractual charge of US$24,000 per day. A manager reports US$72,000 of avoidable delay. What is wrong?
A. Nothing, the arithmetic is correct
B. The daily rate should be halved
C. The response cost was not added
D. Only eligible avoidable time under the actual contract counts, against a supported counterfactual, not every hour in port
D. Only eligible avoidable time under the actual contract counts, against a supported counterfactual, not every hour in port — The result depends on the actual contract, eligible time and supported counterfactual. It is not established by multiplying every hour in port by a daily rate. A demurrage bill alone does not identify the avoidable cause.
Today’s Assignment
Set out the scheduling or readiness decision behind your Session 1 decision, with its confirmed constraints, forecast ranges and accountable handovers.
The constraints. List the confirmed constraints on your decision and their owners by role. Classify each as an engineering or safety limit or a commercial preference, and say who may change the latter.
The forecasts. Which inputs are forecasts rather than confirmed events, the range you would use for each, and the decision deadline by which the forecast must be useful.
Three cases. A short base, delay and disruption case for your decision, and the first constraint that becomes binding.
The handovers. What must be ready before the movement (berth or supply arrival, tank, route, people, documents) and who confirms each. If your business has no marine operation, apply this to the counterpart or supply you depend on.
The honest part. Where your company currently treats a forecast as a fact, or relies on an undocumented override to make the plan work.
