When a decision goes wrong, the post-mortem almost always blames the decider — their judgment, their information, their nerve. Sometimes that is fair. More often, the failure was baked into the conditions around the decision: it was made by the wrong group, against criteria nobody had agreed, in a room where dissent felt expensive, and revisited every week thereafter. Decision hygiene is the unglamorous discipline of those conditions. It assumes the people are roughly as smart as they are, and asks whether the process around them lets that intelligence reach the decision.
Decide what kind of decision it is before deciding it
The first hygiene question sorts the work: is this reversible or not? A reversible decision — a price test, a trial schedule, a pilot — should be made fast, by the person closest to it, and corrected on evidence; demanding executive deliberation for it is not rigor, it is delay wearing rigor’s clothes. The irreversible kind — the hire, the lease, the public commitment — deserves the opposite treatment: slower, wider, explicitly adversarial. Teams get in trouble by running one process for both: agonizing over the reversible while waving through the permanent because it arrived with momentum. Naming the type out loud, at the start, is a ten-second act that quietly fixes the calendar, the guest list, and the standard of proof in one move.
Criteria before options, dissent before consensus
Two more conditions separate clean decisions from contaminated ones. Criteria before options: agree what a good outcome must satisfy — cost, risk, reversibility, what it must not break — before any specific proposal is on the table, because once a favorite exists, criteria get reverse-engineered to crown it. And dissent before consensus: the strongest objection should be heard while it can still change the outcome, ideally by assigning it — “argue the other side as if you believed it” — so that raising it is a role, not a risk. The leader’s opinion comes last in the room for the same reason; an early verdict from the top converts everyone else’s analysis into agreement-hunting. None of this requires genius or new software. It requires a team willing to spend small amounts of structure to protect large amounts of consequence.
Decide once, record why, revisit on evidence
The final hygiene is what happens after. A decision that is silently re-litigated in every corridor is not a decision; it is a permanent campaign, and it taxes every dependent piece of work. So the reasoning gets recorded — briefly, in the open: what was decided, against which criteria, expecting what result, reviewable when. The record does two jobs. It commits the room: disagreement was heard, the call was made, and execution now gets everyone’s full effort, including the dissenters’. And it makes learning possible later, because when the result arrives you can audit the reasoning instead of rewriting history — separating a good decision with a bad outcome, which should be repeated, from a bad decision with a lucky one, which should not. Teams with hygiene compound. Teams without it just re-decide, forever, at full price.
Hygiene has one more quiet virtue: it scales down. The full apparatus belongs to the consequential decisions, but the habits — naming the type, stating the criteria, inviting the objection, deciding once — cost seconds at small scale and run fine in a corridor. A team that practices them on the week’s ordinary calls arrives at the year’s large one with the muscles already built, instead of improvising a process under the worst possible pressure. That is the point of hygiene in every domain it is practiced in: unremarkable habits, maintained in calm weather, that hold their value precisely when the weather turns.
Judge your next decision twice: once by its outcome, and once by the conditions it was made in. Only one of those is under your control beforehand.
Experience it, don’t just read about it
Problem-Solving & Decision-Making — Signature Course No. 4 — builds decision hygiene into a working method across 18 concepts: framing the whole problem before solving a piece of it, deciding under pressure, and recording reasoning that can be audited. Its two capstones produce the real artifacts: The Whole Problem and The Decision Under Fire. The course is $195; one Corporate Library License covers it for every enrolled employee on a team.
