- Who we recruit, and how
- In fintech we test with merchants and account holders mid-task, on their own devices. In clinical software we shadow instead, because interrupting a ward round is not an option. Recruitment method is a scoping decision, and we write it into the proposal so nobody discovers it late.
- What we're allowed to remove
- Some steps exist because a regulator, an auditor or a payer requires them. We ask for the source of each mandatory step early, then design around the ones that are real — usually by resequencing rather than deleting.
- What counts as proof
- Completion rate for onboarding. Minutes per shift for charting. Exceptions cleared per operator for dispatch. We agree the measure with you before design starts, then report against it — including when a change moves nothing.
- Where the system fits
- Regulated products carry disclosure, error and empty states that generic component libraries ignore. Our design systems work treats those as first-class components, not edge cases bolted on at the end.
