The Failure Garden

How does a plausible success plan fail through incentives, governance, technical dependencies and human adaptation — and which mitigations actually change the failure path?

Structured thought experiment, not a forecast. Northstar Mutual is fictional. Every number below comes from a transparent, deterministic model whose assumptions are listed and contestable. Use the outputs to compare plans and argue about mechanisms — never quote them as probabilities about a real company.

    Running the seeded plan…

    Step 1 · Scenario composer

    Compose the stress the plan must survive

    Pick any combination (three or more is where it gets interesting). Stressors interact through named compound effects and through thresholds — governance load past 90%, change load past 100%, FastTrack automation past the 62% hard-case line — so a combination is not the sum of its parts. Step 2 measures that difference directly.

    Stressors (onsets vary ±1 month per trial)

    Step 3 · Failure-path replay

    The most representative failure path

    – ← / → keys work when focus is in the replay

      Step 4 · Mitigation portfolio

      Spend scarce money and scarcer change capacity

      Every selection re-runs the committed scenario with the same random numbers, so differences come from your choices, not noise. Money is a hard limit. Change capacity is soft: you can exceed it, and the model will make you pay in change saturation. Several mitigations slow value or create new risks — read the side effects.

      Marginal analysis — what does each mitigation buy in this scenario?

      Adds each unselected mitigation (or removes each selected one) on its own, 300 trials each, ignoring the budget limit. Positive = better.

      Inspect · Causal failure map

      Who and what makes failure grow

      Stakeholders → initiatives and systems → failure mechanisms ← controls and mitigations. Red heat on a mechanism shows how often it took root in the last run. Select any node (click, or Tab + Enter) to see its causal paths; select a path to read it in plain language with the simulation's own evidence.

      Inspect · Metric corruption lab

      What your success metric teaches people to do

      The chosen KPI is wired into the simulation: it changes hazards (gaming pressure), hides some mechanisms from detection, and drives what the board dashboard shows. Switch it and watch the gap between headline and outcome.

      Inspect · Adversary lenses

      Six people who want this plan to change — for different reasons

      Each critic reads the current portfolio, KPI and simulation through their own incentives. Each is partly right and has a blind spot. Their proposals conflict; applying one is reversible.

      It is month 18. The transformation failed. Why?

      Step 5 · Decision package

      Take the argument into the room

      A local JSON file: scenario, assumptions, mitigations with budget and capacity use, outcome ranges, the representative failure path, dissent (including yours), metric choice and remaining unknowns. Nothing leaves this page.
