Problem discovery function: a useful tool for assessing new product introduction

A quantitative assessment methodology for determining the quantity of real and potential problems during new-product qualification processes is introduced. The process utilizes historical product problem data and applies factors for product complexity, schedule duration, validation stages, product maturity level, corporate commitment to program success, novelty of design, and schedule pressure. Problem discovery trends are developed for historic programs. New products are then scored using these same trends. Predictions concerning the new products and their anticipated set of problems can be drawn. The ability to forecast discovery rates provides significant benefits in terms of substantiated positions for validation duration intensity and resource requirements. Evolution of the problem discovery function process and what improved discovery curves should look like are reviewed with critical discussion.<
