Journal

Notes from work that actually happened.

We share product decisions, engineering lessons, launches, postmortems, and experiments drawn from work we have done ourselves, with enough first-hand context to be useful.

Technical PASS is not Product PASS

What a working document prototype did — and did not — prove about Exam Workbench, and why technical feasibility and product demand need separate gates.

Editorial standard

Every note should add something of its own.

  • First-hand evidence

    Implementation details, screenshots, benchmarks, deployment facts, observations from use, or properly anonymized data.

  • Original decision

    Why a choice was made, what alternatives were considered, and what evidence changed the decision.

  • Reusable learning

    A method someone else can apply, along with the situations where it does not fit.
