01
Brief
Product goal, target user, constraints, files and business target.
Process
A practical path from product idea to production follow-through.
The process is built around the steps your product must pass: validate the brief, design the product, prototype the right questions and prepare for manufacturing.
6 gatesBrief, concept, engineering files, prototype, DFM and pilot approval.
Useful outputsThe workflow creates files, notes and samples your team and suppliers can review.
Supplier-ready outputNotes, files and checklists are organized for quoting, sampling and production decisions.
Project materialsBrief, design, prototype and production details are reviewed together.
Workflow
Six stages with concrete outputs
A milestone-based workflow keeps your team, designers, engineers and suppliers aligned.
02
Concept
Form direction, CMF, use-flow and product experience decisions.
03
Engineering files
Mechanical structure, assembly logic, drawings and supplier handoff.
04
Prototype
Sample route, inspection notes, fit/function checks and revisions.
05
DFM
Material, draft, wall thickness, tooling risk and supplier questions.
06
Pilot
Sample approval gates, QC records and production follow-through.
Tradeoffs
Product development is a chain of investment decisions
The process is designed to make risk visible before your team spends on detailed engineering, samples, tooling or pilot production.
Good industrial design is not only the final rendering.
For physical products, expensive problems usually appear between concept approval, engineering files, prototype samples, tooling quotes and pilot production. The workflow keeps those tradeoffs visible before the next spend.

Gate reviews
What must be approved before moving forward
The goal is to prevent a beautiful concept from becoming an expensive, fragile or hard-to-source product.
| Gate | Approval focus | Typical output |
|---|---|---|
| Brief approval | Target user, product goal, constraints and assumptions. | Product brief, reference board, risk list. |
| Concept approval | Form direction, use flow, CMF and market fit. | Concept boards, renders, design rationale. |
| Engineering file approval | Assembly, structure, interfaces, materials and prototype readiness. | 3D models, drawings and exploded views. |
| Prototype approval | Fit, ergonomics, functional checks and revision list. | Photos, sample notes, test feedback. |
| DFM approval | Manufacturing method, cost drivers, tooling and QC risks. | DFM notes, supplier pack, checklist. |
