Programme decision sequences

Choices now. Information next.

A village-to-festival shuttle, fresh booking evidence and a reservation deadline
Start with the fictional festival shuttle; every experiment keeps its own assumptions.

A first example

One bus or three—and when to decide?

Evidence before commitment asks whether to reserve the shuttle now, wait for new bookings or commission a survey before the hire hold expires.

Eight experiments for exploring decisions that repeat over time. Start with a model, frame a real question, or play through a small example. Each tool keeps its own purpose and assumptions.

The numerical worlds are illustrative. The evidence essay solves its declared small model exactly; the simulators and game do not establish optimal policies or predict real programmes.

When is evidence worth waiting for?

Six mountain-festival examples explore waiting, surveys, evidence latency and adaptive stopping. Inspect every policy path in the declared toy decision tree.

Teaching simulator · illustrative climate world

Climate policy simulator

Compare PFA, CFA, VFA, DLA and hybrid representatives using common seeded shocks. Keep world truth separate from belief; inspect benchmarks, paths, action ribbons and R/I/B framing.

Interactive path diagram

Two climate decision paths

Step through or play two fictional 2028 paths, inspect state/action/information narratives and export the diagram as SVG. Primary sources provide context for the example.

Six-step tutorial

IT project decision tutorial

Work from a software-project narrative to core elements, a proposed mathematical model, policy design, evaluation and iteration. This guide explains a formulation; it does not run it.

Historical precomputed report

Climate SDAM snapshot

Inspect preserved path charts, action sequences, a Sankey view and an editable framing tool. Results are stored figures from an unavailable generating solver with unverified coefficients; controls do not rerun that solver.
