Designin

Design-in is a collaborative engineering process in which a customer or original equipment manufacturer (OEM) evaluates and integrates a supplier's component, module, or technology into a product during the development phase. The goal is to ensure the component meets technical requirements, is compatible with the system architecture, and is supported by the supplier for the product's anticipated lifecycle. Unlike design-out approaches, design-in focuses on selecting and validating an external element rather than replacing an existing one.

In practice, design-in begins with defining performance, power, packaging, and reliability criteria. Engineers assess candidate parts using datasheets, reference designs, evaluation boards, and supplier engineering support. A successful design-in is typically followed by a formal design-win when both parties commit to the supplier for production volumes, pricing, and ongoing support. The process may involve prototype builds, qualification testing, engineering change notification planning, and supply-chain arrangements such as lead-time assessments and obsolescence management.

Benefits of design-in include reduced risk during product development, faster time-to-market, and stronger supplier relationships. Risks include dependency on a single vendor, potential obsolescence, longer qualification cycles, and IP or licensing considerations.

In practice, companies in electronics, automotive, and industrial equipment sectors frequently use design-in to align component selections with long-term availability and support commitments. Efficient design-in often requires early and structured engagement between OEM design teams and supplier applications engineers.
