摘要

当企业外包项目因设计变更产生管理准备金时,其增加的费用通常仅为原合同金额的2% ~ 10%。如果管理准备金超过原合同金额的20% - 50%,则表明外包项目运行的不谨慎。根据公司的政策要求,外包项目必须按照项目的特点和环境所决定的每一个工作阶段的时间表完成招标过程。本研究采用六西格玛定义、测量、分析、改进和控制(DMAIC)方法,对案例公司外包项目中管理储备产生的因素进行了研究。根本原因是没有明确具体负责单位的职责,导致前期需求部门与执行部门、项目工程部门与采购部门沟通不足。前面的过程必须有一个具体的管理程序,通过重新定义每个单元的责任,以避免以后频繁的设计变更。此外,采购部门利用定量成本分析,通过分析供应商的报价来估计储备价格。在最终的效率评估中,本研究验证了改进后的采购案例显著减少了设计变更和管理储备的情况,满足了案例公司的到期日。

Using the Six Sigma DMAIC Method to Improve Procurement: A Case Study
Abstract When a management reserve occurs due to a design change in a company’s outsourcing project, the additional cost is customarily only 2% to 10% of the original contract amount. If the management reserve exceeds the original contract amount by 20% to 50%, it reveals the imprudence of running the outsourcing project. Based on the company’s policy requirements, an outsourcing project must finish the tender process by following the timeline of every work stage determined by the characteristics and environment of the project. This research studied the factors causing management reserve in an outsourcing project of the case company using the Six Sigma define, measure, analyze, improve, and control (DMAIC) method. The root cause was the lack of defining the specific responsibility in charge of unit, leading to insufficient communication between demand and executive departments as well as between project engineering and procurement departments in the preceding process. The preceding process must have a specific management procedure by redefining each unit’s responsibility to avoid frequent design changes later. In addition, the procurement department estimated the reserve prices by analyzing the supplier’s quotes using quantitative cost analysis. In the ultimate efficiency evaluation, this study verified that the improved procurement cases dramatically reduced circumstances of design change and management reserve and met the case company’s due date.
