The owned disciplines, in depth
Summary
The substance behind five of the map's summaries. Testing gives four non-negotiables and, more usefully, the reason they are affordable here: cheap typed objects make the real thing as easy to compose as a stand-in, so the philosophy and the type system are one decision. CI distils a large pipeline into one rule — build once, verify before naming — with the same shape appearing one level up in machine images that must prove themselves twice. Documentation carries the estate's best single idea. Budgets gives three pillars, all publishable as method with none of the figures. Project management supplies the site's most original page: the brief-and-debrief system, demonstrated across thousands of documents and described as a system nowhere.
Key concepts
Key ideas
- Every structural guard encodes a rule that was violated at least once.
- One source, many consumers, no drift — with the counter-example of a second version file read by nothing.
- The rule is right and enforcement is manual, which is the same finding the coding pack reached.
- Opportunity cost as a first-class acceptance, with a named owner.
