Over the past few years, organizations have faced pressure from stakeholders to implement lean principles in their product development processes. However, the existing methods are not capable of measuring the benefits of adopting lean initiatives in the product development process. This research aims to develop a performance measurement model that can measure the effects of implementing lean in the engineering process. Engineering effort is analyzed in order to identify hidden wastes (e.g. inventory in the form of information about product specifications or engineering errors) in the engineering process. The model has been implemented in a civil design process of an engineering consultant company to validate the general applicability of the new model. The implementation of the model provides visibility on the waste hidden in the engineering process and quantifies that waste. The most significant contribution of this research is the development of new performance metrics and a decomposition chart. Finally, performance metrics are properly linked and the model treats lean as a holistic system, quantitatively measuring performance at different organizational levels.

精益产品开发过程的绩效测量

在过去几年中，组织面临来自利益相关者的压力，要求在其产品开发过程中实施精益原则。然而，现有的方法无法衡量在产品开发过程中采用精益计划的好处。本研究旨在开发一种性能测量模型，该模型可以测量在工程过程中实施精益的效果。分析工程工作以识别工程过程中隐藏的浪费（例如，以有关产品规格或工程错误的信息形式存在的库存）。该模型已在一家工程咨询公司的土木设计过程中实施，以验证新模型的普遍适用性。该模型的实施提供了隐藏在工程过程中的浪费的可见性，并量化了这些浪费。这项研究最重要的贡献是开发了新的性能指标和分解图。最后，绩效指标正确关联，模型将精益视为一个整体系统，定量衡量不同组织级别的绩效。
