The first thirty days of an interim CPO engagement
When a product leader leaves suddenly, the damage is rarely the missing strategy. It is the queue. Dozens of small decisions that only that person had the standing to make start backing up, engineering slows down, and within six weeks the team has quietly invented its own priorities because nobody set any.
So the first month is not about vision. It is about restoring decision flow. That means taking over every open decision, closing the ones that can be closed in an afternoon, and being explicit about which ones are deliberately being deferred and until when. It also means turning the weekly rhythm back on: one planning meeting, one review, one written update to the exec team.
The temptation in week one is to restructure. Resist it. You cannot assess a team you have not watched ship anything, and a reorg announced by a temporary leader destroys trust you will need in month three.
What a board expects from an interim product leader
Boards tolerate interim leadership on one condition: visibility. They have just lost the person who explained product to them, and their instinct is that things are worse than they are being told.
The fix is a monthly written product report that does not flatter. What shipped, what slipped and why, what the usage data says, what the top three risks are, and what decision you need from the board. Three pages, same format every month. By the second report the anxiety drops, because the pattern is legible.
The other board expectation is the hiring plan. From month two you should be able to describe the permanent CPO the business needs — not a generic job spec, but a specific description shaped by what you have learned from the inside. That document is often the single most valuable artefact an interim leaves behind.
Interim, fractional or a senior PM: choosing correctly
- —Choose interim when a real role is vacant, a team needs managing, and the board needs a named accountable product leader.
- —Choose fractional when the role does not exist yet, the founder is still the de facto product owner, and what is missing is senior judgement rather than capacity.
- —Choose a senior PM when the strategy is clear and stable and what you actually need is execution throughput. This is cheaper and, when the diagnosis is right, better.
- —Choose an agency when the work is a discrete build with a defined output and no ongoing organisational change required.
- —Choose nothing when the honest answer is that the company needs distribution rather than product leadership. Spending £15k a month on product cover for a business with no route to market delays the real conversation.
Handover: the part most interim engagements get wrong
An interim engagement's value is realised in the last month, not the first. If the permanent CPO arrives to a Notion workspace of half-finished pages and a calendar of meetings whose purpose nobody remembers, the company pays the ramp-up cost twice.
A proper handover is four things: a written state-of-the-product document covering strategy, roadmap, team and known debt; a stakeholder map with the political reality included, not just the org chart; the decision log explaining why things are the way they are; and two to four weeks of overlap where the incoming leader runs the meetings and the interim sits at the back.
I also keep a defined post-handover window — usually two months of light-touch availability — because the questions that matter arrive in week six of the new leader's tenure, not week one.
