Statistical Analysis of New Product Development (NPD) Cycle-time Data
Alpha Technologies recently concluded a comprehensive study of historical NPD performance data (cost, cycle-time, resource requirements, program type and complexity, plans versus actuals, etc.) and has successfully applied the results of this study to make measureable improvements to their NPD process. Probability-based summary data is used to aide in planning and budgeting, set statistically valid continuous improvement targets for performance scorecards, and develop a visual resource management tool for allocation of human resources to present and future NPD programs.
