Product decisions

Decision	Alternatives considered	Chosen approach and cost	Reversal criterion
Express capacity in person-days	Percent allocation; weekly label	Show capacity, time off, commitments, and allocations in days. It does not remove estimation uncertainty.	More than one formative participant cannot translate a real planning input into the displayed day model.
Surface initiative risk from a person-week conflict	Portfolio score; automatic staffing recommendation	Link affected allocations to an at-risk initiative without deciding who moves work.	Participants repeatedly read the signal as a delivery forecast after the explanation is revised.
Separate draft from applied baseline	Immediate-save editing; untracked scratchpad	Keep edits reversible until Apply draft. The comparison adds a review step.	Participants cannot identify which state is current or believe a draft silently changed the plan.
Keep local export	Shared workspace; HRIS connection	Persist in the browser and offer JSON. This limits collaboration.	A specific handoff need, provenance model, and data boundary are evidenced before a shared proposal.

These are product choices for a fictional portfolio sample, not evidence of user preference or a shipped outcome.
