The assumption deserves as much attention as the growth total

The board sees the consequence of a marketing allocation at a different level from the team that makes it. Executives must choose channels, propositions and programmes. Directors need to understand the assumptions on which material commitments depend and whether management can recognise evidence that should change the decision. I have presented the executive account since January 2021, without serving as a director. That experience has made me interested in the translation between a functional report and a question that belongs in collective oversight.

An acquisition total is one example. It can be an accurate record of activated lines and still leave the later commercial relationship largely unexplained. If the strategy depends on repeatable subscriber economics, a board should be able to ask how management follows the cohort beyond the opening offer. That is different from asking directors to select a campaign. The oversight question concerns the basis of the growth account: the observation period, the relevant population, the financial definition and the uncertainty retained in the recommendation.

The fictional comparison between two 2,400-line cohorts taught me to preserve those distinctions. Their ninety-day totals differed, but the groups also differed in offers, commissions and customer mix. My reallocation was a judgement informed by that account, not a conclusion mechanically proved by the count. Finance's involvement was essential because a marketing team should not choose a contribution definition to favour the route it prefers. A board paper should make the cross-functional responsibilities visible enough that a convenient number does not conceal a disagreement about what it means.

Portfolio simplification raises another kind of question. The proposed combination of two brands offered estimated annual communication savings. Retaining the smaller proposition temporarily had a definite additional cost. I supported the extension because the customer's commitment and replenishment choice required a clearer account. The board's useful challenge concerned the decision date and the evidence that could end the extension. Directors did not need to judge the creative treatment to insist that an option had a price, a purpose and a point at which management would stop paying to keep it open.

I would carry the same discipline into a discussion of attribution. A model can describe the last recorded interaction without establishing the incremental effect of another budget amount. But a marketing executive who points out that limitation must still explain why the proposed alternative deserves authority. Uncertainty cannot become a permanent exemption from review. In the disputed C$2.6 million allocation, the retained and transferred amounts, six-month period and later lack of an attributed return all belonged in the record. Removing the last point would make the story easier to celebrate and less useful to govern.

A first director appointment would require a wider contribution than repeatedly making these marketing observations. I would need to understand the company's economics, financial reporting, operating risks, responsibilities and relationships. I would want an induction that addressed the areas outside my functional experience. The chair's feedback would matter because an executive can mistake a detailed question about familiar work for a valuable board intervention. I would need to learn when to examine an assumption, when to rely on a colleague's specialist knowledge and when the discussion has moved beyond my initial framing.

Independence and capacity would also require a specific assessment. I would disclose relevant employer, agency, distribution, advisory and financial relationships before making a commitment. Twenty-four annual days are an initial planning position subject to the actual calendar, preparation and exceptional demands. They are not proof that any proposed role fits. Confidential knowledge from one company should not support another's commercial choices, even when the opportunity appears to sit in a different sector. I would decline if those constraints prevent the contribution the board needs.

The board contribution I would like to explore concerns the assumptions inside a customer-growth story. I can help identify when a measure describes a smaller event than the recommendation implies, or when a simplification removes a commercially meaningful choice. I do not claim readiness to chair a specialist audit or risk committee. A relevant strategy or customer committee could be a place to contribute while learning the wider role. The standard I would set for myself is whether the collective decision becomes clearer, including its uncertainty, rather than whether the board adopts the marketing answer I would have given as an executive.
