As responsibility increases, capable specialists resolve most straightforward questions before they reach the leader. What remains is ambiguous, consequential, and resistant to perfect analysis. The model begins by defining the outcome the organization must achieve and the constraints limiting success. The leader gathers the most relevant available evidence, makes their governing principles explicit, and evaluates options against those principles rather than mood, politics, or isolated preferences. When evidence cannot determine a uniquely correct answer, informed judgment closes the gap and a timely decision is made. Because these choices have broad effects, the model also emphasizes the quality of relationships with founders, executives, and peers who help make and support them. Outcomes then become feedback for refining future principles and judgment.

Core principles

  • 01Senior leaders inherit problems without obvious solutions.
  • 02Clear goals and constraints provide stable decision criteria.
  • 03Incomplete information does not remove the need to decide.
  • 04Strong executive relationships improve the quality and resilience of difficult decisions.

How to run it

  1. 1

    Define the Objective

    State the specific outcome the team or business must achieve at its current stage.

    Pro tip Use a result that can distinguish relevant options from attractive distractions.

    Watch out A vague objective allows any preferred option to appear justified.

  2. 2

    Name the Constraints

    Identify the limits on growth and success, including money, time, capability, market conditions, and organizational capacity.

    Pro tip Separate binding constraints from inconveniences.

    Watch out Ignoring a real constraint does not make it disappear.

  3. 3

    Gather Decision-Relevant Evidence

    Collect information that could materially change the choice and stop when additional research has low expected value.

    Pro tip Ask specialists what they know, what they disagree about, and what remains uncertain.

    Watch out Do not use endless research to postpone an uncomfortable decision.

  4. 4

    Apply Explicit Principles

    Evaluate options using stable beliefs about customers, strategy, ethics, people, and the organization's needs.

    Pro tip Write the principles before debating the final options.

    Watch out Principles invented after choosing are rationalizations.

  5. 5

    Use Judgment and Decide

    Where evidence remains incomplete, use experience and informed instinct to select the best available option within the required timeframe.

    Pro tip Document the decisive assumptions so they can be reviewed later.

    Watch out Confidence should not be presented as certainty.

  6. 6

    Review the Consequences

    Track the outcome, identify which assumptions held, and refine the decision principles for the next ambiguous problem.

    Pro tip Review both decision quality and outcome quality because good decisions can still produce bad outcomes.

    Watch out Do not rewrite the original rationale after seeing the result.

In the wild

Reallocating a Marketing Organization

A CMO must choose between preserving several established programs and funding a new growth priority. They define the next-stage objective, identify budget and capability constraints, evaluate each option against explicit strategic principles, consult the CEO and functional leaders, and decide despite uncertain forecasts.

The allocation is explainable, timely, and grounded in organizational needs rather than attachment to existing programs.

Common mistakes

Waiting for Perfect Information

The hardest executive decisions often remain uncertain even after all reasonable evidence is collected.

Using Instinct Without Principles

Instinct becomes difficult to audit or communicate when it is detached from goals, constraints, and explicit beliefs.

Confusing Emotionlessness With Indifference

A decision can serve the organization while still being communicated and implemented with empathy.

Is it for you?

Best for

It is best for executives and functional leaders facing high-impact choices with incomplete evidence and multiple defensible options.

Not ideal for

It is not ideal for routine decisions that can be resolved through established policy, direct measurement, or specialist expertise.
