These internal Product Builders records are teaching examples, not verified challenge entries. They show the original Bet, the evidence that forced a revision, what can honestly be claimed, and what remains unknown.

Turn a discovery lesson into a runnable field kit

Should Product Discovery remain an explanatory lesson or become a workflow a builder can run end to end?

Original Bet
A staged five-day workbench will be more useful than another page of methods, questions, and rubric copy.
Threshold
One saved flow must frame the decision, recruit, capture interviews, synthesize evidence, force a call, and export the memo.
Current result
The static lesson was replaced by a 15-action workbench with evidence gates, local persistence, memo export, and a reusable agent skill.
Next move
Measure sprint starts, completed evidence records, exported memos, and return-to-finish behaviour before claiming learning impact.

Observation → consequence

  1. Problem

    The page described discovery but gave the builder nowhere to conduct it.

    Replace passive instruction with a staged working surface.

  2. Revision

    A method, question list, exercise, and rubric still left the hard operational steps implicit.

    Add recruiting, structured evidence, decision gates, and required artifacts.

  3. Current evidence

    The complete workflow is usable and testable; real completion and outcome data is not yet available.

    Keep the claim at “runnable,” instrument use, and do not call the skill mastered from checkboxes.
