The Warning Came First: What to Do When a Supplier Signal Appears After Approval

By Alexander Jaiyesimi MSc MCIPS · Founder, SupplierSense · 9 min read

On the morning of 2 October 2018, a window pane weighing around 130 kilograms fell from a penthouse at The Corniche, a residential development on Albert Embankment in London, and struck Mick Ferris, a 53 year old coach driver, on the street below. He was killed instantly. It is a case that deserves to be treated with care, because a person lost his life, and because the criminal proceedings have now resulted in jury verdicts, with sentencing of the two convicted companies still to follow.

There is one detail in the public record that matters for anyone who works in supplier assurance. The fall in October 2018 was not the first time a window had come away from that building. More than a year earlier, in August 2017, a panel had already fallen from the same development. No one was hurt on that occasion. The warning, in other words, came first.

This article is not about construction, and it is not an attempt to relitigate a case the courts have decided. It uses a widely reported set of events to examine a procurement principle that sits at the centre of modern supplier risk management, and at the centre of what SupplierSense means by supplier intelligence. The principle is simple to state and difficult to live by. A material signal about a supplier can appear at any time, including long after that supplier has been approved. When it does, the question is not whether the signal proves anything. The question is what a disciplined organisation does next.

Watch: SupplierSense Intelligence Briefing 001, The Warning Came First. The briefing sets out the case and the core procurement lesson in seven minutes. The article below adds the procurement analysis, the evidence discipline and the method behind it.

What the public record shows

The Corniche was designed by Foster + Partners and completed in 2019. The development sits on the south side of the Thames and comprises several hundred apartments across a cluster of towers. The window that killed Mick Ferris fell from a penthouse around twenty six storeys up, a drop of roughly ninety metres.

The matter was prosecuted by the Health and Safety Executive and tried at Inner London Crown Court. Four organisations stood trial, each charged with failing to discharge a duty under section 3(1) of the Health and Safety at Work etc. Act 1974: Foster + Partners as architect, Wintech as a facade engineering consultancy, St James as the developer, which the court heard had taken on the principal designer role from 2015, and Lindner Prater as a specialist contractor.

On 7 August 2026, after a trial of around five weeks, the jury returned its verdicts. St James and Lindner Prater were found guilty. Foster + Partners and Wintech were acquitted. Sentencing of the two convicted companies was listed for 24 September 2026, and had not taken place when this article was written. Those are the findings of the court, and they are stated here neutrally and without embellishment.

The prosecution's case, as reported, was that the earlier fall in August 2017 should have prompted a fundamental reassessment of the outward opening penthouse windows, and that this did not happen to the degree the circumstances required. That was the prosecution's argument. The jury heard the full evidence, convicted two of the four defendants and acquitted the other two, and sentencing remains to be concluded. It is not the purpose of this article to go behind those findings, to assign responsibility more widely than the court has, or to suggest that any particular different action would certainly have changed the outcome. The value of the case, for procurement, lies at the level of principle rather than culpability.

The limits of point in time supplier assurance

Most supplier assurance is built around moments. A supplier is assessed at onboarding. It is reassessed at tender, at renewal, perhaps at an annual review. Each of these is a point in time. The assessment is thorough, the file is complete, the box is signed, and then the relationship moves into the long stretch between reviews where very little is actively watched.

Point in time assurance is not wrong. It is necessary, and it is often done well. The difficulty is that it captures a supplier as it was on the day it was assessed, and a supplier is not a fixed object. The approval is a photograph. The supplier is a film that keeps running after the shutter closes.

This is the structural gap that continuous supplier monitoring is designed to close. Onboarding due diligence tells you whether a supplier met your standard at the point of entry. It tells you very little about whether that supplier still meets it eighteen months later, when the contract is live, the exposure is real and no formal review is scheduled for another two quarters. The Corniche is a construction case, but the shape of the problem, an approval given, followed by a later event that changes what is known, is one every procurement professional will recognise.

What changes after a supplier is approved

Suppliers change, and so do the environments they operate in. Between two formal reviews, a supplier can be sold, restructured, refinanced or quietly hollowed out. Its ownership can change. Its key people can leave. Its largest customer can fail upstream and take its cash flow with it. A regulator can open an investigation. A court can list a case. An adverse media story can surface a practice that was always there but never visible to you.

None of these events waits for your review cycle. They arrive on their own schedule, and they change the information available about the supplier whether or not anyone in your organisation is looking. Operational incidents, regulatory action, financial distress, legal proceedings, sustainability and ESG exposure and reputational events can each alter the picture materially. The question is not whether such events occur. They occur constantly across any supplier base of reasonable size. The question is whether your organisation sees them close to when they happen, or reads about them much later, after they have already become your problem.

Procurement takeaway. Treat supplier approval as the beginning of a monitoring relationship, not the end of an assessment. The most important information about a supplier is often the information that arrives after you have already decided to work with them.

A signal is not a verdict

Here the Corniche case offers an unusually precise piece of language, because it produced a literal verdict. In a courtroom, a verdict is the end point of a long, disciplined process. Evidence is gathered, tested and weighed. Both sides are heard. Only then, and only by the people whose role it is to decide, is a conclusion reached. A verdict is not the first thing that happens. It is the last.

In supplier risk, procurement teams too often treat the signal as if it were the verdict. A single adverse media hit, one late filing, one data point on a dashboard, one automated score turning amber, and the instinct is either to act on it immediately as though it were proven, or to dismiss it immediately as noise. Both responses skip the process that turns information into a decision.

An earlier incident, a warning that comes first, is a signal. It is a reason to look, not a finding in itself. It does not, on its own, establish what happened, what it means for a particular supplier and contract, or what should be done. Those are conclusions, and conclusions are earned through evidence and judgement, not asserted from the appearance of a signal. This is the discipline that separates mature supplier intelligence from a stream of alerts. The signal opens the inquiry. It does not close it.

A signal is a reason to look. It is not, on its own, a reason to act, and it is never a verdict. The discipline is in what happens between the two.

Supplier Intelligence and Procurement Intelligence are not the same thing

This is the distinction that runs underneath everything above, and it is the one SupplierSense cares about most.

Supplier Intelligence is the information and the signals available about a supplier: its ownership, its conduct, its financial position, its sustainability exposure, its operating context and the related entities around it. There is a great deal of it, most of it is public, and it updates continuously. An earlier incident, a filing, a court listing, a change of director, a piece of adverse media: each of these is supplier intelligence. It may be relevant. But relevance alone does not make it decision ready. A supplier signal that is true, and even important, can still be the wrong thing to act on today, or the right thing understood in entirely the wrong way.

Procurement Intelligence is supplier intelligence that has been carried through the rest of the journey. It has been verified, so you are acting on what actually happened rather than on a headline. It has been interpreted through procurement expertise, so it is understood in the context of this supplier, this contract and this exposure. It has been prioritised by commercial relevance, so a genuinely material change is not lost among a hundred trivial ones. And it has been communicated so that a procurement professional can determine what requires attention and why. A raw signal, a source record, a data point, an automated summary or a score is not, by itself, procurement intelligence. It is the raw material from which procurement intelligence is made.

The Corniche case, read as an analogy, is a case about the gap between the two. A signal existed. The disciplined question is always what was done with it: whether it was verified, interpreted, weighed and acted on, or whether it was noted and allowed to recede. Supplier intelligence tells you something has changed. Procurement intelligence tells you whether it matters, and what to do about it.

Continuous supplier monitoring, done proportionately

If material signals arrive between reviews, and if a signal is a reason to look rather than a conclusion, then the practical answer is continuous monitoring. Not continuous alarm, and not continuous reassessment of every supplier as though each were in crisis. Continuous visibility, paired with proportionate review.

Continuous monitoring does two things well. First, it shortens the distance between an event and your awareness of it, so that a change in a supplier's ownership, filings, financial signals, legal exposure or public conduct reaches you in something close to real time rather than at the next scheduled review. Second, and this is the part that is easy to miss, it creates a defensible trigger for proportionate action. When a signal appears, a monitored organisation has a process waiting for it: a way to decide, quickly and consistently, whether this particular signal on this particular supplier warrants a closer look, a conversation, a formal reassessment, or nothing more than a note on file. The alternative, in which signals either never arrive or arrive with no process to receive them, is how a material change becomes visible only in hindsight.

Procurement takeaway. The goal of continuous monitoring is not to react to everything. It is to make sure that nothing material passes unseen, and that when something material does appear, there is a proportionate and consistent process ready to weigh it.

The SupplierSense Procurement Intelligence Method

The discipline that turns a signal into a sound decision can be written down. SupplierSense expresses it as the Procurement Intelligence Method:

Signal, then Evidence, then Interpretation, then Judgement, then Action.

A signal appears: an earlier incident, a change, a data point, a piece of adverse media. It is the prompt, not the answer. The next step is evidence: establishing what actually happened, from reliable sources, rather than acting on the first version of the story. Then interpretation: understanding what the evidence means in the specific context of this supplier, this contract, this category and this exposure, because the same signal can carry very different weight in different settings. Then judgement: a procurement professional deciding whether the risk picture has materially changed, drawing on experience that no data point can replace. And only then action: doing the proportionate thing, which may be enhanced monitoring, a supplier conversation, a formal reassessment, an escalation, or a documented decision that no change is warranted.

The essential principle is that the appearance of a signal should never, by itself, produce a supplier verdict. The five questions the Method asks are deliberately plain:

· What happened?

· What evidence supports it?

· What does it mean in this supplier and contractual context?

· Does it materially change the risk picture?

· What, if anything, should procurement do?

Technology can carry a signal to the right person far faster, and can connect signals that would otherwise sit in separate places. It does not, and should not, make the consequential decision at the end. The judgement in step four is a human one, and keeping it there is not a limitation of the method. It is the point of it.

Questions procurement teams can take from this case

The Corniche is a construction case with a specific and now largely settled set of legal findings. The procurement questions it raises are general, and they are worth asking of your own supplier base regardless of sector.

· When a material event affects one of your approved suppliers, how would you find out, and how long would it take?

· Do you have a defined, proportionate process for what happens when a signal appears, or does each one depend on whoever happens to notice it?

· Can you tell the difference, quickly, between a signal that changes the risk picture and one that does not, and is that judgement recorded so that a decision to do nothing is a decision rather than an omission?

· Are you treating supplier approval as a conclusion or as the start of a monitoring relationship?

· Where a signal turns out to matter, can you show the path from signal to evidence to interpretation to judgement to action?

None of these questions requires a new system to start answering. They require a shift in posture, from assessing suppliers at moments to watching them over time, and from treating a signal as a verdict to treating it as the first step in a disciplined process.

How SupplierSense helps

SupplierSense is a Procurement Intelligence platform built on a straightforward idea: much of the information that would change a procurement decision is already public, already changing, and already sitting between your formal reviews, unread. The problem is rarely a shortage of supplier data. It is the absence of anything that continuously reads that data, connects it, and brings the material changes to the right person in a form they can act on.

SupplierSense works from the outside in. It continuously monitors public supplier signals, ownership and related entities, financial indicators, sanctions, adverse media, ESG exposure and country risk across a supplier portfolio, so that a material change on an approved supplier surfaces as it emerges rather than at the next scheduled review. It is designed to support the Procurement Intelligence Method, not to replace it. It brings the signal and helps establish the evidence and interpretation. The judgement, and the decision, remain with the procurement professional, where they belong. SupplierSense does not make supplier decisions on the strength of an external signal alone, and it is not a substitute for formal due diligence, supplier engagement, accreditation, audit or specialist assurance.

Procurement intelligence for supplier risk, ESG and due diligence, without supplier participation. See the change before it becomes your problem.

Key takeaways

· The warning often comes first. Material information about a supplier frequently appears after approval, on its own schedule rather than yours. The question is whether you see it in time to think about it.

· Point in time assurance is a snapshot. Onboarding and periodic reviews capture a supplier as it was on the day. Suppliers and their environments keep changing in between.

· A signal is not a verdict. An earlier event, a data point or an alert is a reason to look, not a conclusion. Acting on it as though it were proven, or dismissing it as noise, both skip the process that matters.

· Supplier Intelligence is not Procurement Intelligence. Raw signals become decision ready only once they are verified, interpreted, prioritised and communicated. Relevance alone is not enough.

· Continuous monitoring plus judgement. The aim is not to react to everything, but to ensure nothing material passes unseen, and that a proportionate, consistent process is ready when it does. The final judgement stays with procurement.
