SRAI EXECUTIVE PATHWAY · EP-M03

Deciding When Evidence Is Incomplete

Update beliefs transparently, compare asymmetric consequences and test whether the preferred action remains defensible before choosing to ACT, PILOT, WAIT AND LEARN or ESCALATE.

01 / EXECUTIVE OUTCOME

Make uncertainty visible without allowing it to paralyse the decision.

Document the prior, evaluate the diagnostic weight of new evidence, update beliefs, compare posterior expected losses and preserve the authority of accountable human decision-makers.

02 / GOVERNED DECISION SYSTEM

Connect evidence, consequences and authority in one reviewable record.

  1. 01

    Decision and authority

    State the decision, scope, horizon and accountable owner.

  2. 02

    States and prior

    Declare consequential states, omitted possibilities and prior provenance.

  3. 03

    Evidence and likelihoods

    Assess diagnostic weight, dependence, quality and possible distortion.

  4. 04

    Posterior and range

    Update beliefs and report credible ranges rather than false precision.

  5. 05

    Loss and constraints

    Compare asymmetric consequences while protecting rights and safety.

  6. 06

    Sensitivity and information

    Locate reversals and test whether additional evidence is worth its cost and delay.

  7. 07

    Review and authorization

    Record triggers, exit rules, affected groups and the final human sign-off.

ACT

Authorize bounded action

Evidence and declared losses support action within explicit controls.

PILOT

Learn at acceptable cost

A limited intervention can resolve material uncertainty safely.

WAIT AND LEARN

Delay deliberately

The value of additional evidence exceeds the cost of waiting.

ESCALATE

Refer the decision

Missing states, constraints or authority exceed the current mandate.

03 / VIDEO LESSON

Deciding when evidence is incomplete

Follow the complete executive workflow from prior beliefs and diagnostic evidence through posterior loss, sensitivity, information value and accountable authorization.

04 / LEARNING RESOURCES

Five resources for executive study, practice and reproducible analysis.

Use the lesson and brief to prepare, the exercises to rehearse the decision process, the presentation to review the narrative and the notebook to challenge the calculations.

LEARN

Canonical executive lesson

Study how evidence updates beliefs without replacing accountable judgment.

BRIEF

Executive brief

Use the concise reference for evidence review and authorization meetings.

Open PDF ↓
PRACTISE

Practice exercises

Apply updating, loss, sensitivity and information-value reasoning.

Open PDF ↓
PRESENT

Executive presentation

Review the governed decision sequence and sector applications.

Open PDF ↓
ANALYSE

Companion notebook

Reproduce the calculations and test uncertainty, reversals and missing states.

05 / PRIORITY SECTORS

One decision discipline, four public-value settings.

Agriculture anchors the canonical case. Education, Health and Habitat demonstrate how the same reasoning transfers while sector owners retain responsibility for evidence, losses, constraints and authorization.

06 / TECHNICAL CONTINUITY

The executive treatment preserves the former Book 6 Chapter 3 technical core.

The module retains Bayesian updating, likelihood ratios, asymmetric loss, decision thresholds, sequential evidence, sensitivity analysis, model misspecification, distributional effects and value of information.
