How do I practice workflow inputs and outputs?

The most direct way to practice workflow inputs and outputs is through a focused exercise: Choose one workflow you perform regularly. Write down, explicitly, the complete input specification: every piece of information, every material, every precondition that must be true before the first step can execute. Then write the complete output specification: the concrete deliverable, its format, and the criteria that determine whether the output is acceptable. Compare what you wrote to how you actually start and finish this workflow in practice. The gap between your specification and your practice is the ambiguity your workflow currently tolerates — and ambiguity is where errors, delays, and rework hide.

Common pitfall: Treating input-output specification as obvious and therefore not worth writing down. The failure is not imprecise specification — it is absent specification. You know what the input 'should be' and you know what 'done' looks like, but you have never made either explicit. The result is that every execution requires you to re-derive the specification from memory, and each re-derivation introduces subtle variation. Monday's 'done' is not Thursday's 'done.' The inputs you gathered last time are not quite the inputs you gathered this time. The workflow produces inconsistent outputs not because the process is flawed but because the specification was never stable.

This practice connects to Phase 41 (Workflow Design) — building it as a repeatable habit compounds over time.
