Purpose: There are several KPI(key performance indicators) models: BSC(balanced scorecard), IPOO(Input-process-output-outcomes) indicators, QCDP(quality-cost-delivery-productivity) indicators. This paper analyze these models and gives some suggestions to help the effective usage of KPI. Methods: This paper reviews and summarize the criteria to evaluate the PI(performance indicators) through literature review. Evaluation and analysis on the PI factors of the KPI developing models is performed by the criteria. Results: Criteria to evaluate the PI, which can be used to evaluate the goodness of PI is suggested. This paper also proposes some suggestions for the KPI models and their factors for the effective development of PI in the organization. Conclusion: This research will help the managers to develop and select useful PI and KPI for their business and processes.

A design process for the structure-borne noise in a passenger vehicle is presented. The proposed process is improved from the previous one. The major difference between the current and last ones is that most of the countermeasures should be developed before fixing a tool for structural parts. This is requested for QCDP(Quality, Cost, Delivery and Productivity) by the design engineers. The proposed one consists of 4 steps: Problem definition, Cause analysis, Development of counter-measure and Validation. Based on the general rule: divide and conquer, the complex problem can be simplified into a few critical sub-systems through the first step: Problem definition. Secondly, the critical causes can be identified for the critical sub-systems through the second step: Cause analysis. Thirdly, effective countermeasures are investigated and produced through the third step: Countermeasure development. The proposed countermeasures are finally validated in the forth step: Validation.
