| OWS is not only the core product of ROADM network but alsohigher complex optical passive device in fiber communicationfield. OWS s trial manufacture process management is atypical project of high-tech. product.Firstly, to introduce OWS s project background andresearch significance, By way of SWOT, market positioning,forecast and feasibility analysis to set OWS s project maintarget.Secondly, to expound OWS s product principleã€techniqueparameters and process flow chart, then to make statisticdefective products information of trial manufacture bystages, with first pass yield only66.7%from12unitsproducts, it caused Sep. s market requirement reduced tohalf than Aug. then finished failure analysis of one modulerejected from customer with typical failure mode.Thirdly, to identify project organize structure of OWS sproject, then to finish theory analysis of quality controlmanagement, quality risk management and their applicationsin OWS s project, then expounded schedule management theoryand applied PERT and training plan to the project. Further, to apply WBS, CPM, EVM etc. methods to OWS strial manufacture project as case introduction, projectleader guided team to do engineering analysis on the failuresof schedule, cost, quality, finally defined their failuresroot cause are related to operating skill s proficiency andoptical design, the most effective solution is theimprovement on optical collimator s diameter from0.5mm to0.7mm, it contributed first pass yield improvement from66.7%to95%then reduced the rework cost.The last part is the summary and future prospect．... |
