Application on Interaction to New Product Development

The study explores the elements of interaction among related departments and the management of project life cycle during new product development. The study takes laptop industry as a research objective, and adopts a single-case-study method. The results show the elements of interaction among related departments such as product lines, product map, information of defective product, service information system and five major design principles. The five major design principles are fewer parts count, easy assembly, quicker test, convenient repair, and three savings (labor saving, time saving, parts saving). The study proposes PPLC model for the management of project life cycle which consists of eight inner cycles: quotation request, design, experiment, engineering, pilot run, pre-mass production, mass production, and end of life cycle. There is also a new finding 6σ improvement plan, and finally the study proposes two propositions for future research.
