Engineering Operations Services

From design validation through mass production ramp — every phase of the wireless electronics product lifecycle.

01 / NPI OPERATIONS

New Product Introduction (NPI)

End-to-end NPI program management from EVT through MP gate sign-off — milestone planning, cross-functional RACI, build packages, and deviation control.

  • EVT / DVT / PVT / Pilot build planning & execution
  • Gate review packages and exit criteria definition
  • BOM rationalization, AVL management, EOL risk assessment
  • First Article Inspection (FAI) and golden unit management
  • DFM / DFT review with CM and ODM partners
  • Yield ramp strategy: targets, containment, escalation paths
Reduce time-to-market by up to 40% with proven NPI methodology.
