Ambiguity taxes teams. In perception, confusion clusters around the boundary; in projects, it clusters around vague handoffs, soft deadlines, and unlabeled columns. The cure isn’t more data… it’s sharper signals. State the decision rule. Define the unit of analysis. Specify which rows belong to the same person. Then over-communicate once and measure the rework you prevent. You’ll feel “awkward” the first week; that’s the sensation of replacing assumptions with agreements. Clarity looks expensive up front and turns out to be the cheapest thing you can buy.
