Metrics for Evaluation of the Product Design Process

9634768 Ullman 这笔赠款为开发可供执业工程师和管理人员用来评估和改进产品开发过程的指标提供资金。 这些指标将衡量当前流程，指出潜在的流程效率低下之处，并协助评估新的最佳实践。 这些指标将基于产品开发过程中使用的信息演变和决策结构的特征。 设计过程稳健性的概念将作为这些措施的基础。 当识别出非稳健流程时，本研究期间制定的指南将提供改进的机会以及记录提高设计流程效率的潜力的能力。 以产品为基础的行业面临着持续的压力，需要在更短的时间内、用更少的资源设计和生产新的、质量越来越高的产品。 伴随着这种压力，人们认识到已知且受管理的产品开发流程的重要性。 许多大公司花费了大量的时间和精力来记录他们的开发过程。 该流程集成了许多行业范围内的最佳实践（例如，质量功能部署、功能建模、实验设计、装配设计）。 许多小公司才刚刚开始识别并尝试控制决定其产品演变的流程。 大型和小型公司都需要更好的工具来衡量产品设计流程 ISO-9000 等标准要求产品开发流程，但没有提供如何开发、衡量和确保此类流程的有用性的指导。 这项研究将产生行业可用于自我评估和指导的工具，以改进其产品设计流程。

9634768 Ullman This grant provides funding for the development of metrics usable by practicing engineers and managers to evaluate and improve the product development process. These metrics will measure the current process, point to potential process inefficiencies, and assist in the evaluation of new best practices. The metrics will be based on characterizing the information evolution and decision structure used during product development. The concept of design process robustness will be developed as a foundation for the measures. When non-robust processes are identified, guidelines developed during this research will provide opportunities for improvement and the ability to document the potential for increased design process efficiency. Product-based industries are under continuous pressure to design and produce new, and increasingly higher quality, products in less time and with fewer resources. With this pressure has come the realization of the importance of a known and managed product development process. Many large companies have spent considerable time and effort documenting their development process. Integrated within the process are many industry-wide best practices (for example, quality function deployment, functional modeling, design of experiments, design for assembly). Many small companies have only just begun to identify and attempt to control the processes that determine the evolution of their products. Both large and small companies need better tools for measuring the product design process Standards, like ISO-9000, require a product development process but give no guidance on how to develop, measure and ensure the usefulness of such a process. This research will result in tools usable by industry for self assessment and guidance to improve their product design process.
