This study brought in performance matrix, factor analysis, and theory of constraints
under the systemic framework of Six Sigma which is usually used to improve product
quality, to construct a new model for product development performance evaluation
and improvement. The model was then verified with the product development of
a semi-conductor equipment manufacturer. Hopefully, the proposed model can provide
corporations a solution to systemically perform evaluation of performance, reveal
problems, analyse causes of the problem, establish improvement scheme and execute
the improvement scheme for the product development procedure and can up-lift the
competitiveness of the corporation through this elevating improvement cycle.
