Validating Market Entry Assumptions in Four Weeks

Start with what the board actually needs to believe

Before you commission any external work, write down the three or four assumptions the board's approval rests on. Not the market thesis. The stakeholder assumptions underneath it: which regulator will treat this as within their remit, which policy direction they're moving in, how incumbents will react, whether key intermediaries will distribute or block you, and what political sensitivities sit above the technical decision.

Most teams skip this step and go straight to interviews. They come back with interesting colour and no way to tell the board whether the plan still holds. Write the assumptions as testable propositions. "The PRA will view this as a straightforward variation of permission" is testable. "Regulators are supportive" is not.

Separate the assumptions that matter from the ones that don't

You have four weeks, maybe six. You cannot test everything. Rank your assumptions by two criteria: how much of the business case depends on them, and how confident you actually are (not how confident the sponsor is). The ones that are load-bearing and weakly evidenced are your targets. Everything else waits.

Be honest about internal groupthink here. If three people in the room built the thesis together, their shared confidence is not independent validation. Treat it as one data point.

Map who can actually move the decision

For each load-bearing assumption, list the people whose view determines whether it holds. Not the org chart. The actual influencers: the policy lead inside the regulator, the trade body technical committee chair, the two or three senior figures at incumbents whose public position sets the tone, the Treasury official who briefs ministers, the consumer body that files objections.

What most people get wrong: they interview the accessible, not the decisive. A friendly former regulator is easy to speak to. Their view is often two years out of date. Prioritise people currently inside the decision, or one step from it.

Commission external work you cannot do yourself

Your own team cannot ring the regulator and ask what they think of your plan. Even carefully framed conversations under your own name will be read as signalling intent, and will bind you before you're ready. This is where third-party stakeholder research earns its fee: attributed or non-attributed interviews conducted by someone who is not you, structured against your specific assumptions, delivered fast.

Brief the researcher on the propositions, not the conclusions you want. Ask them to look for disconfirmation. If you get a report that tells you everything is fine, push back and ask what evidence would have changed the answer.

Run parallel tracks, not a sequence

Four weeks does not accommodate waterfall. Run three streams simultaneously: external stakeholder interviews (15 to 25 conversations, targeted), a regulatory precedent review (how has this authority actually decided analogous cases in the last three years, not what the guidance says), and a competitor and adjacent-market signal scan (what have incumbents said publicly, what job adverts and consultation responses reveal about their intent).

Triangulate. A single senior view is a lead, not a finding. When three independent sources describe the same dynamic, you have something the board can act on.

Write the findings against the original assumptions

When the evidence comes back, resist the urge to write a narrative report. Go back to your original propositions and mark each one: confirmed, contradicted, partially supported, or still unknown. The "still unknown" category is the honest one and the one most often deleted before board papers. Keep it.

For each contradicted or partially supported assumption, state what the plan needs to change, or what condition needs to be met before proceeding. This is what turns validation work into a decision, rather than a document.

What good looks like at the board

A one-page assumption register showing what you believed, what you tested, what you found, and what changed. Board members with any experience will trust a paper that admits two assumptions did not survive contact with external reality far more than one that claims full confirmation. The former reads as due diligence. The latter reads as advocacy.

Your next move

Before the end of this week, write the assumption list. If you cannot get it to a single page of testable propositions, you are not ready to commission external work, and you are not ready for the board.
