PDE's product design process, a multi-stage, customizable framework that emphasizes gating reviews, continual client involvement, and strong communication to ensure successful design outcomes across overlapping phases from identifying needs to production ramp-up. Key Points PDE’s design process is divided into discrete, sometimes overlapping stages tailored per project. A gating review process is used to assess progress at each stage. Client involvement is continuous, reflecting the emphasis on communication for success. The process progresses from identifying customer needs to concept development and system-level design. Each stage includes planned design reviews to monitor significant phases. The workflow incorporates testing and refinement before moving toward production ramp-up. The process is flexible: not all projects require every stage to achieve a successful design.
