Methodology

How decisions are made — the decision loop from requirements through candidate solutions to scoring on Gate · Fit · Cost · Risk. The doctrine is rendered straight from the skill references, so it never drifts.

The reading path

Read these in order

The topics build on each other — from the timeless structure to worked examples. If the model is new to you, read them top to bottom; if you’re already inside it, jump straight to what you need.

Start here
The model is the foundation — the timeless structure (the funnel, tools vs. solutions, the four axes, forks, the scenario). Read it once before anything else; everything else builds on it.
