Abstract
Abstract We introduced a benchmarking methodology for long-term improvement as significant strategy and method. Using the methodology, we benchmarked manufacturing management practice for 12 IC packaging plants from Taiwan’s 9 main IC packaging companies of 12 factories in 1998. The gross production of such 9 companies constitutes 80% of domestic production. The contributions of this work include: 1) Establishing a systematic benchmarking methodology as an effective improvement strategy and approach. The methodology includes: a) systematic measurement indices, b) identifying improvement drivers, c) regression analysis for performance and determinant indices relations, d) input/output efficiency analysis, e) indices analysis, and f) individual feedbacks. 2) Applying the methodology to benchmark 12 IC packaging plants. We offered a systematic index model for the industry, found some 10 improvement drivers, provided efficiency analysis, indices benchmarking feedback to the participating plants.
