Kehinde Eyitayo Oyediji’s co-authored research examines a decision facing Nigerian energy companies after a procurement investigation: what evidence should management require before declaring a weakness corrected? The question connects his work in management analysis with supplier verification, payment approval and accountability for corrective actions. A revised policy records an intended response. The transactions which follow show whether staff apply the required checks. His research addresses how companies should examine those records, assign responsibilities and independently assess whether their response addresses the failure investigators identified.

Mr Oyediji co-authored “A Governance Framework for Procurement Policy Reform after Forensic Investigations in Nigerian Energy Companies” with Ifeoma E. Okoli and Olaolu Samuel Adesanya. Published in December 2020 in Adhyayan: A Journal of Management Sciences, the paper proposes a process for linking findings to controls and evidence of operation. Mr Oyediji works as a management analyst at KPMG. The framework is the authors’ joint proposal, and its discussion concerns their research rather than KPMG’s services. Four months after publication, the study raises practical questions about supplier records, receipt certification, payment authority and the decisions required before corrective actions close.

The framework connects investigative findings to assigned responsibilities, operating records and independent verification. Its scope runs the length of the purchasing cycle: supplier registration, bidding, receipt certification, payment, and emergency purchasing. And it rests on a distinction that sounds simple and is not, reviewers need operating evidence to assess the effect of a recorded change.

A record is not a result
A signed policy shows what management intended. A training register shows who turned up. A revised system setting shows a technical adjustment was made.

Each of those records answers a useful question. None of them answers the one that matters: did the required scrutiny actually happen in the transactions that followed?
The framework Mr Oyediji co-authored links every supported finding to its underlying failure mechanism. Management then assigns an accountable owner, defines the operating rule, and specifies what an independent reviewer should examine. Closure depends on assessing both the design of the response and its performance.

“An investigation establishes where a process failed. Management then needs evidence showing whether the response addresses the weakness,” Mr Oyediji said.

That places transaction review, including the evidence supporting each decision, at the centre of the approach.

Why the failure mechanism matters
Consider an unsupported payment. An unauthorised change to a supplier’s bank account calls for a different response than an unreliable delivery certificate. An emergency exception approved without sufficient examination raises a third set of responsibilities.

Treat them as interchangeable and you get a general response that leaves the specific weakness intact.
The point is not abstract. Extra training offers limited protection where excessive system access lets payment details be changed without review. Another signature offers limited protection where the approver has no dependable evidence of what was received. The authors therefore insist on a stated relationship between the supported cause, the proposed control and the test used to judge performance.

The bank account test
Supplier banking details offer the clearest illustration.
Under the proposed procedure, a material change to an account triggers independent confirmation through an established, verified communication channel before any payment goes out. The person who enters the change should not be the person who authorises payment to the revised account. The record preserves the change, the confirmation and the relevant payment evidence.

A reviewer then asks whether verification happened at the right time, and whether the person who did it had enough independence to say no.

It is a procedure that addresses a defined exposure rather than adding an approval step whose purpose nobody can explain.

What did the company actually receive?
Receipt certification gets comparable attention, because payment depends on establishing what the company got.

A purchase order records what was required. Delivery evidence should identify quantities, condition, and technical acceptance where needed. For services, the equivalent record concerns completed work or agreed milestones. The framework ties those records to invoice examination and payment approval. A discrepancy needs an explanation backed by evidence and reviewed by someone with the authority to act on it.

Within the research, the receipt process is the bridge between the purchasing commitment and proof of performance. The reliability of those records shapes the quality of every payment decision that follows.

Signatures are not scrutiny
The paper also asks whether approval structures produce independent judgment, or just the appearance of it.

Different job titles mean little when one person effectively directs both reviewers. Several signatures resolve nothing when staff approve transactions without reading the documents behind them. An electronic trail proves an action occurred; it says nothing about the substance of the review.

The authors separate responsibility for implementing a control from responsibility for assessing whether it works. Where staffing limits true separation of duties, the framework proposes documented compensating review and explicit acknowledgement of the remaining exposure. The aim is to locate where meaningful scrutiny happens, and to check that the reviewer has the evidence and the authority to perform it.

“Our proposed framework connects each supported finding to an accountable owner, an operating rule and independent verification,” Mr Oyediji said. His explanation connects the team’s proposed process with the responsibilities required to assess each corrective action.

When competition isn’t competition
Competition has its own trap. Several quotations do not amount to independent bidding when the suppliers share economic control.

The proposed procedure therefore weighs ownership information, relevant relationships, and the response to concerns that surface. Technical acceptance and commercial comparison are treated separately, because prices reflect different assumptions about delivery, freight, warranty and contractual obligations. The evaluation record should make those differences visible. Later variations matter too, whenever they change the original commercial arrangement.

For Mr Oyediji and his co-authors, reform is not a single fix. It runs across the purchasing cycle, requirement definition, supplier selection, contractual changes, delivery and settlement.

The emergency problem
Emergency purchasing brings operational reality into the room.
An energy company facing an urgent maintenance requirement needs a workable route to equipment or services. A procedure built only around routine purchasing invites undocumented workarounds whenever delay carries a cost.

The paper proposes a separate emergency process with a recorded reason, supplier choice, expected value and approving authority. The decision is reviewed once the immediate pressure has passed. Repeated emergency orders for predictable needs would raise questions about planning and supplier availability. Urgency gets its own procedure, with responsibility and evidence attached for later scrutiny.

Pascal Dozie on implementation and verification
Pascal Dozie, the businessman, philanthropist and founder of the former Diamond Bank Plc, discussed the relationship between assigned responsibility, operating evidence and independent review.

“A procurement policy should make responsibility clear and give management reliable evidence for reviewing decisions,” he said. “Following an investigation, the organisation needs to establish whether the identified weakness has been addressed in practice. Independent verification provides a basis for this judgment. The procedure also needs to preserve timely purchasing, particularly where maintenance requirements are urgent. The value of the proposed framework would depend on how well organisations apply these responsibilities and test the results.”

Asked about the model itself, Dozie said its strength lies in what it refuses to assume.
“The framework does not treat a corrective action as a formality to be ticked off a list. It asks a harder question: has the weakness actually been addressed in the way the company now buys? That is the right question, and it is the one that is most often skipped. It connects the finding to a named owner, a defined rule and an independent check, so that responsibility does not dissolve somewhere between the investigation report and the next purchase order.”

He also discussed Mr Oyediji’s co-authored work and its focus on purchasing transactions.

“Mr Oyediji and his co-authors have done something useful here. They have taken a problem that is usually discussed in the abstract, governance, controls, accountability, and put it back where it belongs, in the daily transactions of an energy company. They have also been honest about the limits of their own work, which is more than many reform proposals are willing to be. I would commend them for that discipline, and for writing something that management can actually use.”

On validation, Dozie was direct about what would prove the framework right or wrong.
“The real test is not whether a policy document is signed. It is whether the next transaction shows the check took place. So validation has to be built on evidence, not assurance. Companies should look at a defined period, a defined set of transactions, and ask whether the control operated and whether the reviewer was independent. If the answer is no, that is not a failure of the framework, it is the framework doing its job, telling management that the exposure remains open. The framework earns its value the first time it stops a premature closure.”

He added that context would matter in any assessment.

“Any validation has to account for changes in staffing, volume, systems and operating pressure. And an organisation should be careful about reading a fall in reported incidents as proof of improvement. Better detection can raise the numbers; weaker monitoring can lower them. The evidence that counts is whether the required checks occurred, and whether someone with the authority to challenge them was looking. That is where the framework, properly applied, will prove its worth, and where it will fail if it is applied as paperwork.”

His assessment puts implementation and operational consequences side by side with verification, a reminder that a control which stops the work is not a control that lasts.

The closure rule
Everything converges on closure.
Reviewers assess three things: whether the revised control addresses the supported failure mechanism; whether operating transactions show the required checks taking place; and whether an authorised body accepts whatever exposure remains. If a test fails, the response is further implementation, redesign, or a separately authorised acceptance decision.

The closure record identifies the period reviewed, the transactions examined, the exceptions and the reasoning behind the outcome. Management then has a documented basis for explaining why an action was closed, and, if failures continue, grounds for reopening it.

Completing an assigned task and correcting the underlying weakness are, the authors argue, two different judgments.

“A revised policy records the intended change. Subsequent transactions show whether the required checks occur. The decision to close a corrective action should rest on this evidence,” Mr Oyediji said. This closure requirement is central to the framework he co-authored.

What it means on the ground
For procurement teams, the implications land on daily work. Supplier account changes would carry defined verification requirements. Receipt discrepancies would have an accountable owner and an escalation route. Emergency purchases would keep records for later examination. Oversight functions would receive evidence tied to investigative findings rather than completion dates alone. Management would receive unresolved matters that demand decisions, repeated exceptions, failed verifications, unresolved exposure.

If later testing supports the approach, it would give companies a clearer basis for deciding whether to close, reopen or redesign a corrective action. Those benefits depend on application, and on what the records show.

The cost side
The authors are not blind to the cost. More review steps consume staff time, and documentation requirements shape whether suppliers take part. A procedure that improves verification but delays essential maintenance creates a new problem of its own.

The proposed evaluation therefore tracks approval time by purchase category and urgency alongside evidence completeness and how exceptions are handled. Routine orders and emergency replacements are analysed separately. Supplier participation also comes under scrutiny where requirements burden smaller firms without improving the evidence that matters to a purchasing decision.
Operational consequences sit inside the assessment, not outside it.

The question that remains
Mr Oyediji’s co-authored work connects his field of forensic and management analysis with a specific governance problem: how organisations assess corrective action after an investigation. The paper’s proposed contribution is a closure rule requiring adequate control design, evidence of operation and an authorised decision on unresolved exposure. These requirements give later evaluators defined questions to test. They do not establish that a company has adopted the framework or achieved measured improvements.

The research asks how companies should evaluate their response once investigators have found a weakness and management has assigned corrective actions. Future testing would need to establish whether independent review catches premature closure, whether procedures address supported causes, and whether urgent purchasing keeps a workable route.

Those questions connect the framework to decisions made inside an organisation. Supplier records, delivery confirmations, exception reviews and payment approvals after implementation provide the evidence management needs.

In the end, the transactions decide. They show whether the intended change took effect, and whether more work is required.
