The Incoming Brief: Giving Your Next Adviser a Running Start

Most UK organisations commission external advisers with the intention of building on what has gone before. In practice, the knowledge that would make that possible is often treated as a closing ritual: a final workshop, a folder of slides, a polite offer of availability for questions. By the time the next adviser arrives, the people who held the context have moved on, the slides have lost their supporting detail, and the organisation pays again — in senior time, in repeated interviews and in the slow reconstruction of history.

The remedy is not a larger handover document. It is a smaller, better-targeted one, prepared before the next engagement begins and owned by the client rather than the departing adviser. Call it the incoming brief: a concise pack that tells a new adviser what has already been decided, what cannot be changed, what has been tried and what remains unproven.

The expensive part is often the beginning

Clients tend to scrutinise the end of an engagement closely. They review deliverables, settle invoices and assess whether the promised value arrived. The beginning of the next engagement receives far less attention. Yet the first few weeks are when an adviser is most dependent on the client for context. Without a reliable account of prior work, mobilisation becomes an exercise in archaeology.

That is not to say every hour spent understanding the organisation is wasted. A new adviser should form their own view. But there is a difference between independent judgement and avoidable ignorance. If a previous programme was stopped because a supplier contract could not be varied, the next adviser should not have to discover that through a series of meetings. If a board has already ruled out a particular operating model, saying so early is not a constraint on fresh thinking; it is a fact that shapes it.

The commercial consequence is straightforward. Time spent reconstructing known history is time not spent on the problem the client is actually paying to solve.

What belongs in the pack

The incoming brief should be short enough to be read in one sitting and structured enough to be challenged. Six sections are usually sufficient.

Decisions already taken. Record the choice, the rationale, the decision owner and the date. Where a decision was contested, say so. A new adviser needs to know which decisions are settled and which are merely assumed to be settled.

Constraints that will not move. These may be regulatory, contractual, technical, financial or political. In a UK context, they might include data protection obligations, sector-specific rules, board reserved matters, lease terms or a fixed funding window. Constraints should be stated plainly, with the source of the constraint and any flexibility that exists.

Attempts that did not work. This is the section most often omitted and most valuable to include. Describe what was tried, why it stopped and what would have made it viable. A failed attempt is not a failure of the organisation; it is evidence. Withholding it invites repetition.

Open assumptions. List the things currently taken as true but not fully verified. These might concern customer behaviour, cost estimates, staff capacity or supplier performance. An incoming adviser should be able to see which assumptions are load-bearing and which are provisional.

People and relationships. Identify who carries the work, who makes decisions, who influences them and who will need to be convinced. Org charts rarely capture this. A short paragraph on the informal map is often more useful than a diagram.

Data, models and documents. Say where the relevant material lives, who owns it and what its limitations are. If a previous model was built on assumptions that have since changed, note that. A link to a spreadsheet without context can be worse than no link at all.

Who should write it

The client should own the incoming brief. The outgoing adviser can and should contribute, particularly on decisions, assumptions and failed attempts. But the client is best placed to validate what is accurate, what is sensitive and what should be shared with a new supplier.

In practice, an internal sponsor or programme lead should maintain the document during an engagement, not assemble it in the final week. A short update at each steering meeting is usually enough. When the engagement ends, the pack is already largely complete. The closing conversation becomes a review rather than a reconstruction.

This also changes the nature of the handover clause in consultancy contracts. Instead of asking for a closing presentation, clients can ask for a maintained incoming brief, updated at agreed intervals and handed over in an editable format.

How to use it with a new adviser

Send the pack before the engagement starts, not on the first morning. Ask the incoming adviser to read it and return two things: a list of questions and a short note on what they would challenge. That single step does several things at once. It tests whether the adviser has absorbed the context, it surfaces gaps in the pack and it gives the client an early signal of how the adviser thinks.

The first meeting can then be spent on the questions rather than on a general history. The adviser can test the assumptions, probe the failed attempts and confirm which constraints are genuinely fixed. The client can correct omissions and add context that should not have been written down.

It is also worth agreeing, at the start, that the incoming adviser will maintain the pack for their successor. That expectation is easier to set at the beginning than to impose at the end.

The objections, briefly

Some clients worry about confidentiality. The answer is redaction and judgement, not omission. The pack does not need to contain commercially sensitive detail to be useful; it needs to contain enough context to prevent wasted effort.

Others worry about the time required. A useful incoming brief can usually be assembled in a few hours if it has been maintained during the engagement. Reconstructing it from scratch at the end takes longer and produces a poorer result.

A third objection is that a brief will constrain fresh thinking. It will not, provided it records facts and decisions rather than preferred solutions. A new adviser who understands the boundaries is better placed to challenge them intelligently.

A small discipline with a clear return

The incoming brief is not a bureaucratic artefact. It is a commercial instrument. It reduces mobilisation time, improves the quality of early hypotheses and gives the client a stronger hand in procurement conversations. It also makes a simple point to every adviser: we value continuity, and we expect you to contribute to it.

For UK organisations that rely on a succession of advisers, the discipline is worth adopting. The alternative is to keep paying for the same learning twice.
