IPD Study Notes: How Technical Reviews Structure Product Development

IPD (Integrated Product Development) originates from the PACE theory of PRTM and was refined through IBM practice; it defines six stages—concept, planning, development, verification, release, and lifecycle—with clear decision‑review gates that focus on business aspects such as market positioning and profitability.

The technical review (TR) objective is to scrutinize product technical details to ensure design, functionality, reliability, and manufacturability meet expectations, serving as a quality‑control mechanism that detects issues early, prevents defect propagation, and reduces rework and schedule loss.

Typical IPD implementations set 6‑8 technical review points; Huawei’s widely adopted scheme uses seven points (TP1 and TR1‑TR6). The logical flow follows demand definition → solution design → module development → prototype verification → system acceptance → mass‑production release, with each TR acting as a prerequisite for the next stage. Key terminology includes DFX (design for X, covering DFM, DFT, DFS), BBFV (basic functional verification), SDV (system design verification), SIT (system integration test), and SVT (system volume production verification).

For complex system products with mass production (e.g., smartphones, switches, projectors), the IPD process typically employs seven primary technical review points covering the full development chain. The review system logic ensures that each stage—TP1 through TR6—acts as a gate, and the associated table and diagram illustrate the review flow.

For simpler, high‑volume products such as chemicals or food, the process can be streamlined to five stages with fewer review points, as shown in the accompanying diagram, reflecting reduced complexity and lower innovation risk.

For large, high‑value custom equipment (e.g., excavators, CNC machines), the development follows a five‑stage model with five primary technical review points, focusing on both functional and performance validation in a single prototype and ensuring manufacturing and supply‑chain readiness before volume production.

The overall process logic forms a closed‑loop quality‑control system: TP1 anchors market and customer requirements; TR2 reviews overall technical solutions; TR3 validates module designs; TR4 checks module implementation; TR5 confirms pilot‑run performance; and TR6 performs final validation of supply‑chain capability, certifications, and beta testing before product release.
