6 notes

Evaluation

Design evaluation coverage around the decision

Build cases that exercise meaningful product situations. Make the relationship between the decision, the coverage, and the claims explicit.

  • Evaluation design
  • Test cases
  • Product behavior

Evaluation

Diagnose failures from the complete execution

Trace the first observable departure from expected behavior, follow its consequences, and preserve the questions the evidence cannot yet answer.

  • Failure analysis
  • Observability
  • Product behavior
5 MIN READ↗

Systems design

Build retrieval you can inspect and explain

Preserve the path from source material to working context so a team can understand omissions, test transformations, and verify the resulting task.

  • Retrieval
  • Context engineering
  • Provenance

Engineering practice

Design experiments that can change your next decision

Choose a learning objective, a credible comparison, and an outcome that reflects accepted work. Preserve enough context to revise the recommendation.
