02 / Content and UX decisions

Decisions

DDR-001 · Content decision

Require every material critique to connect evidence, consequence, principle, next move, and proof.

DDR-002 · Experience decision

Preserve productive struggle: teach the reasoning, then give a bounded next action instead of silently completing the work.

03 / Delivery evidence

Delivery evidence

  1. 01

    Learn, critique, studio, case-study, and interview modes.

  2. 02

    Reusable critique and case-study methods.

  3. 03

04 / Role signals
