One line in the plan, two owners
Annual planning has reached the growth line, and two decks are competing for it. Marketing's case shows pipeline models, channel returns and a forecast of what an incremental few million would produce next year. Technology's case argues that the platform is at capacity, that the next stage of growth is physically constrained by systems, and that deferring the work again converts a budget line into an outage. Both sponsors have lobbied before the meeting. The CFO, who will carry the blame for either miss, is expected to arbitrate by Friday.
The comparison nobody runs
The two cases are written in different currencies of proof, and that difference decides more than the content does. Marketing's evidence is precise and contestable: attribution figures the CFO can audit, and can also discount, because measurement produced by the channel being funded invites scrutiny. Technology's evidence is vague and alarming: capacity thresholds, dependency chains and incident risk, none of which converts naturally into revenue. So finance can interrogate one case line by line and can only take the other on trust. A rigorous review of the marketing numbers next to a nodding acceptance of the technology narrative, or the reverse, is not a comparison. It is two separate conversations sharing a meeting.
How the choice actually gets made
- Recency of pain: whichever function is associated with the most recent visible failure loses ground, whatever the current case says.
- Credibility balances: a CMO who over-promised last year is repaying the debt now; a CTO who cried wolf on a previous platform is discounted whether or not this wolf is real.
- Escalation skill: the sponsor with the better relationships shapes the pre-meeting, and the pre-meeting shapes the meeting.
- The 50/50 split: dividing the line keeps the peace and frequently underfunds both cases below the level at which either delivers.
- Deferral: the decision moves to a committee or the mid-year review, which is a decision for the status quo wearing procedural clothes.
What each wrong outcome costs
Fund marketing and the platform constraint, if real, arrives as an incident during the very growth the spend produced, with the repair executed at emergency prices. Fund technology and a genuine market window may close while the organisation rebuilds plumbing customers never see. Split the budget and both risks survive at slightly reduced probability. The subtler cost is behavioural: functions learn how the arbitration is really won, and next year's cases are engineered for the contest rather than for accuracy. Marketing adds more decimal places. Technology adds darker warnings.
Forcing the cases into one currency
The CFO's leverage is to set the terms of evidence rather than judge the submissions as they arrive. Require both cases to state their claim as a change in the same numbers: revenue, cost, or a priced risk, with the assumptions listed and owned. Require each sponsor to write the strongest version of the other's case, which surfaces what each actually concedes. Price the technology risk properly (probability, blast radius, remediation cost at emergency rates) instead of accepting adjectives, and discount the marketing forecast by what its measurement cannot prove. The two cases will still not be perfectly comparable, but they will be comparable enough to make the residual judgement visible, which is what arbitration should mean.
Who should sit outside the contest
Everyone inside the building has a position: the sponsors are advocates, their teams depend on the outcome, and the CEO often carries a legacy preference for one side. The useful outside input comes from operators who have owned this trade-off with real money: former CFOs and P&L leaders who funded the platform and watched the market window close, or funded the campaign and paid for it at the next outage. Selected senior operators from the Global Board can read both cases in confidence and say which claims match their experience and which read as contest engineering. That input reaches the CFO before the decision hardens, without either function feeling audited.
