Hardware buying guide
Define the decisions you need to make and the deliverables you need to own, from early concepts to a package ready for engineering or manufacturing.

Build a industrial design brief →03 / Compare
Compare milestones, deliverables, revision rounds, and engineering boundaries. A concept project and a manufacturing-ready design package have different scopes.
Compare provider details →Specify what the engagement must decide: user interaction, physical form, ergonomics, product architecture, or a manufacturing handoff. A rendering, an appearance model, and an engineering prototype are different deliverables. Design 1st describes design work alongside engineering and manufacturing transfer; ask which disciplines your proposal actually includes.
Choose a decision owner and a review date for each milestone. Define what constitutes acceptance and how additional concepts or revisions are commissioned. Plan the next team's handoff while you define the project, so the final presentation is not the only usable output.
Use these evidence requests to resolve the project scope before ordering.
On smaller screens, scroll across to read the evidence and open questions.
| Question | Evidence to request | Needs clarification |
|---|---|---|
| Which disciplines are included? | A work breakdown with named engineering and design responsibilities. | A portfolio is used in place of a defined engagement scope. |
| How will concepts be selected? | Agreed user and technical criteria and an explicit decision gate. | Only appearance is reviewed despite usability or integration requirements. |
| What can the next team use? | A file and documentation handoff list with review responsibilities. | Manufacturing-ready is promised without naming the package or open engineering work. |
Illustrative project: a handheld inspection tool needs glove-friendly controls and space for an existing electronics module. Set a first milestone around use scenarios and concept tradeoffs, then a physical mockup review, then the engineering handoff. Identify whether sealing, thermal design, electronics integration, and production drawings are included or commissioned separately. Approve the next milestone against the agreed evidence.
Ask for the discipline breakdown. The engagement may connect the two, but a design concept does not automatically include detailed engineering, tolerancing, or production drawings.
Define the editable files, design rationale, prototype results, and next-stage documentation needed by your engineering or manufacturing team.
Match milestones, staffing, deliverables, revision allowance, and assumptions. Ask how changes and approval delays affect the budget and schedule.

Documented service scope
These records have an official capability source. Details may cover one service within a provider's wider offering; confirm the process and material combination for your project.
Processes: Industrial design, User-centered product design
Scope and buying questions: Agree on concept alternatives, usability evidence, CAD deliverables, and the final handoff. Is detailed mechanical engineering included or supplied separately? Clarify who resolves design changes that emerge during tooling and first production samples.
Official capability source →Processes: Industrial design, Mechanical engineering, Electronics engineering, Embedded software development, Prototype development, Design transfer
These are product-development services rather than a catalog of manufacturing materials. Agree on design deliverables, prototype acceptance criteria, intellectual property ownership, and manufacturing-transfer responsibilities.
Official capability source →Processes: Product strategy, Industrial design, Product engineering, Prototyping, Manufacturing sourcing support
Scope and buying questions: Specify the engineering and prototype deliverables independently of a marketing engagement. Who owns CAD, firmware, tooling files, and manufacturer relationships? What evidence must the prototype produce before authorizing tooling or a production order?
