Ninety Minutes Well Spent: A Practical Stress Test for Your Next Big Decision

Most UK SMEs do not fail because they make too few decisions. They fail because a handful of large ones are taken on thin evidence, under time pressure, in a room where nobody is paid to disagree. A capital purchase, a senior hire, a second site, an unfamiliar export market: each can absorb a year of retained profit, and each is routinely approved after a board pack and a good feeling.

The 90-minute clarity audit is a way of interrupting that pattern without commissioning a full strategy review. It is a single structured conversation, run once, with a small group, designed to test whether a decision holds together when exposed to a handful of disciplined questions. It costs a morning. It frequently saves considerably more.

Why ninety minutes is usually enough

Longer sessions expand to fill the time available. Participants arrive unprepared, the conversation drifts into operational detail, and the decision itself is deferred to a follow-up meeting that nobody diarises. The time constraint is deliberate. A decision that cannot survive ninety minutes of focused interrogation is unlikely to survive a year of trading.

The format also suits the reality of a small leadership team. In a business of twenty to two hundred and fifty people, the individuals who hold the relevant knowledge are usually the same people running the operation. Removing them for three days is impractical; removing them for an hour and a half is merely inconvenient.

Three conditions before the session begins

First, the decision must be capable of being stated in one sentence, with a date attached. If it cannot, the group is not yet ready to audit it.

Second, the room should contain at least one person who is not an advocate for the proposal. A finance director, a non-executive, an operations lead from another site. Somebody whose job is not to make the idea succeed.

Third, one person must be appointed to record the answers verbatim. Not to summarise, not to interpret. The value of the exercise lies in hearing the original wording read back a fortnight later.

The five question blocks

Each block takes roughly fifteen minutes and should be completed before moving on.

The decision itself. What precisely is being decided, by whom, and by when? What happens if the business decides nothing at all? The last question is often the most revealing, because inertia is a choice with its own costs and benefits, and it is rarely evaluated on the same terms as action.

The evidence. What do we know, as distinct from what we believe? Which figures are audited, which are modelled, and which were produced by the person proposing the spend? A useful discipline is to write each claim on a line and mark it K for known, A for assumed, or H for hoped.

The mechanism. By what chain of events does this expenditure become revenue or savings? Name each link, from the spend to the customer or the cost line. Then ask who is accountable for the third link. Proposals frequently survive the first two links and collapse at the third.

The failure case. If this goes wrong, how would we know, and how quickly? What is the cost of stopping or reversing it? A proposal without an exit estimate is not a plan; it is a commitment with the downside withheld.

The opportunity cost. What is the best alternative use of the same money, the same management attention and the same twelve months? If the answer is vague, the comparison has not been made.

Red flags worth naming out loud

Certain patterns recur across sectors and company sizes. A financial case that rests on a single scenario, with no sensitivity analysis, is a forecast dressed as a fact. An advocate who also supplied the numbers has not been independently tested. A mechanism that runs from spend to return via the word efficiency has no mechanism at all.

Other signals deserve equal suspicion: urgency that cannot be traced to a specific deadline; an exit cost dismissed as pessimism; a success criterion with no date attached; and a proposal that has quietly grown in scope since it was first discussed, without a corresponding change in the case for it.

The output: one page, four headings

The session should end with a single page. Under Decision, state what is being decided and when. Under Evidence, record which claims are known, assumed or hoped. Under Conditions, list what must be true, or what must be resolved, before the commitment is made. Under Review, set the date on which the decision will be reassessed against its own stated measures.

That page is the deliverable. It is short enough to be read, specific enough to be argued with, and dated, which means it can be revisited honestly.

What the audit is not

It is not a strategy review, and it will not substitute for legal, tax or technical due diligence. Nor is it a device for making difficult decisions comfortable. Its purpose is not to produce certainty but to make plain what the business is betting on, and at what price.

Some decisions will pass the audit comfortably. Others will pass with conditions attached, which is often the most useful outcome: a smaller first commitment, a pilot with a defined test, a hire deferred until a specific milestone is met. A few will fail, and the failure will be evident within the hour rather than eighteen months later.

Making it stick

Diary the review date before anyone leaves the room. Circulate the one-page record within forty-eight hours, while memories are still accurate. At the review, read the original wording aloud before discussing what has happened since. That single practice does more for decision quality than most governance frameworks, because it makes the reasoning visible and therefore correctable.

The audit demands no software, no consultant and no budget line. It demands ninety minutes, one dissenting voice and the willingness to write down an assumption and call it one. For a UK SME weighing a decision that will shape the next two or three years, that is a modest price for a clearer view.
