Design controls

TL;DR

The FDA / ISO design-development discipline — planning, inputs, outputs, review, verification, validation, transfer, changes and the DHF.

21 CFR 820.30 (and ISO 13485 §7.3, EU MDR Annex II §6) requires that every Class II, Class III and select Class I device be developed under a controlled process: design and development plan, design inputs (user needs + regulatory + standards), design outputs (drawings, specs, code, labels), design review at defined milestones, design verification (do we meet the input?), design validation (does it meet user needs?), design transfer to production, design changes under change control, and a Design History File (DHF) that proves the design was developed per the plan.

The DHF is the lifelong evidence package an inspector asks for first.
