Process templates for product planning and definition

In order to establish the planning and the definition processes to realise products that inspire high perception and favourableness in purchasing agents, we have developed a template for product planning and definition processes. This template includes a strategic analysis, which focuses on the target client, needs analysis, quality function deployment and base/option part optimisation. We have also attempted to apply the template to product planning and definition for the elevator business. We have ensured that the following effective activities can be realised by the proposed methods: (1) Hypothesis planning, such as a purchase decision factor, based on competitiveness analysis and customer value chain (business domain/stakeholders structure) analysis. (2) Hypothesis verification of newly arising needs based on Voice of Customers (VOC) and analysis, including text-data mining. (3) Optimisation of base/option part and variety, based on the results of VOC analysis and evaluation of the cost.

Management method for LSI wafer fabrication facilities

A method is described for analyzing factors causing variations in manufacturing facilities in which monitored data that correlate with product quality are collected during routine operation. By using a method of accumulating deviations from the center value of the monitored data and quality data in time sequence, the fluctuation point can be detected, the correlation checked, and the cause of the variation discovered.<<ETX>>
