Abstract: Lean manufacturing has been the buzzword and gained a lot of interest in the industry since the last decade. It has become a phenomenon in the industry and a widely accepted fact that operation excellence will be the key focus area to provide the leading advantage against the various competitors.

This paper presented a case study on manufacturing test time optimization using DMAIC approach. Successful restructuring of an advance flying probe (AFP) test program had enabled the test time reduction by more than 50.0%. Statistical analysis and six sigma (6s) first pass yield (FPY) monitoring for 6 months after new test program implementation had confirmed that the manufacturing test time optimization was achieved without compromising the product quality. In correlation to the manufacturing test time optimization achieved, it came along with a very significant return of investment (ROI) for the effort put in. The case study shared here is evidenced of DMAIC as a structured tool that can be effectively used for manufacturing processes improvement opportunities.
