Hardware Development

Hardware development involves the design and manufacture of electromechanical devices. It includes CAD models, prototypes, manufacturing documentation, and certifications.

Process Overview​

Principles​

  • Analyze and select hardware components based on performance, environmental and certification requirements, component obsolescence, manufacturability, and cost.
  • Verify the solution in steps (simulations, 3D printed parts, mock-ups, proof of concept, prototypes).
  • Demonstration of intermediate deliverables to key stakeholders for early feedback.
  • Provide electrical, mechanical, and thermal design with appropriate simulations (virtual prototypes).
  • Review the design to catch problems early on.
  • Early integration and testing of hardware and software.
  • Provide input for end-user documentation.
  • Secure firmware deliveries to electronic manufacturing services (EMS).
