Why strategy execution fails: the assumptions nobody was watching
Execution almost never fails the way a project does — visibly, on a date, with someone accountable. It fails the way a map does: the document stays exactly as good as the day it was written while the territory moves, and every decision made from it is still internally consistent. The failure is not a lack of discipline or talent. It is that the plan’s load-bearing sentences — the assumptions — had no owner, no cadence and no verdict, so nobody could see the moment they stopped being true.
Nobody owns the check. A strategy document gets an owner the day it is approved; its assumptions do not. Six months later the people who could contradict an assumption are in different roles, and the one person who still remembers the exact wording is the one least likely to be in the room when a decision quietly depends on it. Ownership of the document is not ownership of its claims.
Each report looks fine alone. The decay is spread across quarters. Any single interim report reads as reassurance — revenue grew, costs came down, the outlook paragraph says “in line”. Only the comparison against the original commitment shows the drift, and that comparison lives in neither document. Targets versus interim reports is where it has to be made.
Disconfirming evidence has no slot. An organisation reads news that confirms its plan and skims news that contradicts it — not from dishonesty, but because the contradiction has nowhere to go. There is no register entry waiting for it, no agenda item it maps to, so it becomes a feeling in one manager’s head instead of a fact on a page.
The language replaces the evidence. “On track”, “broadly as planned” and “in line with expectations” are verdict-shaped words that require no evidence to say. Once they enter the reporting rhythm, they do the job the check was supposed to do, and the plan degrades silently behind them.
§ 02 · What the quiet failure costs
The decisions stay rational. The premises under them expired.
The expensive part is not the strategy that missed. It is the specific, well-run decision — an investment, a hiring plan, a market exit — that was justified in a board paper by an assumption which had already broken, with nobody in the room able to say so. The reasoning reads fine line by line. The premise is the only thing wrong with it, and the premise is not in the paper.
This is checkable in public documents, not just in boardrooms. One public audit, of Kemira’s 2024 long-term targets, paired the company’s own margin target of 18–21% with the 16.1% its own H1 2026 report states — a figure that appears in neither document next to the other. The assumption broke in public, on schedule, and nothing in either document marked the moment.
The remedy is not another planning cycle. It is maintenance, and maintenance has a shape — the same one aviation and military planning settled on long before software:
Named, one sentence each. “The market grows” cannot break. “Organic revenue growth stays above 4% a year through 2028” can. An assumption is only watchable if it is written specifically enough that a dated figure could contradict it — the extraction step in checking whether assumptions still hold.
Evidence with a date, or nothing. A verdict without a source is the “on track” problem again. Each check pairs the assumption with the newest figure that speaks to it, and records where that figure came from and when it was published. Sources without dates are treated as background, not evidence.
Three verdicts, honestly given. Holds, broken, unresolved. “Unresolved” is the one organisations avoid, because it admits the evidence does not exist yet — but it is the only honest verdict for a young target, and recording it with the date the decisive figure will arrive is what turns waiting into watching.
A cadence faster than the drift. Quarterly reporting is the fastest most evidence arrives, but the check itself has to run more often than the decisions it protects. A weekly pass over the assumption set — sources checked, nothing new, move on — is what keeps a contradiction from sitting unseen between two reporting dates.
This is not a thought experiment — the same maintenance loop runs weekly on 16 Nordic strategies and government programmes, with every verdict carrying its source and date. Recent records:
- Metso — Metso's end-2028 targets, one year into 'We go beyond.'0 broken · 8 unresolved · 1 hold
- Elisa — Elisa's medium-term targets for 2027, checked against the record so far2 broken · 3 unresolved · 3 hold
- UPM — UPM's long-term financial targets, reported through 20252 broken · 4 unresolved · 5 hold
Send the strategy. The register comes back free.
An Assumption Audit does the extraction and the first evidence pass on the strategy you already have: the load-bearing assumptions named in one sentence each, checked against dated public evidence, each verdict carrying its source. The register is free; the full pass is €390 when you want the record you can point at.
Living Plans, the business behind this guide, is itself run by AI agents on NanoCorp — the weekly loop that maintains the public audits maintains this page too.
