Two decks, both plausible, pointing apart
The customer research says demand is softening. The pipeline data says the strongest quarter in three years is forming. Both were assembled carefully, both survive a first round of questioning, and each function stands behind its own. The meeting adjourns with an action to "reconcile the numbers", which over the following fortnight turns into two teams building better cases for the figures they already had.
Why the numbers were never going to match
The datasets are answering different questions and were built under different incentives. A pipeline reflects what salespeople are rewarded for entering; research reflects what respondents say, which is not the same as what they will do; finance's model reflects the assumptions someone chose when it was built years ago. Each function trusts the instrument it controls, partly because it understands that instrument's flaws and has learned to live with them. Data does not interpret itself. Every number arrives carrying the choices of whoever collected it, and those choices, not arithmetic errors, are where most conflicts live.
The three standard mistakes
- Picking whichever number supports the plan leadership already prefers, then calling the decision evidence-based.
- Averaging the figures into a midpoint that no dataset supports and no one believes.
- Commissioning a third study whose main output is delay, and whose findings will be contested by whichever side it disappoints.
- Letting the question escalate into a credibility contest between teams, which the decision does not need and the organisation pays for long afterwards.
Reconcile at the level where the truth lives
Interrogate provenance, not conclusions: what exactly was measured, from whom, over what period, and what incentives touched the collection. Then decompose both cases into their assumptions. Conflicts that look total usually localise to one or two variables, a conversion rate or a market definition, and a targeted test of that variable is cheaper than another full study. Ask each side in advance what evidence would change its mind. If the answer is nothing, you have learned that this is a values conflict wearing data's clothes, which is useful to know before the next meeting. Where the stakes justify it, run a small real-world trial both sides accept as decisive before it starts.
Where outside judgement comes in
Operators who have run comparable businesses have watched these instruments perform over full cycles. They know which kind of signal predicted reality and which kind flattered the forecast, because they carried the consequences either way. Independent perspectives do not add a third dataset to argue about. They add pattern recognition about which class of evidence deserves the benefit of the doubt in this specific kind of call.
