Major assets such as buildings, infrastructure and defence systems are long term investments that require many outsourced sustainment activities to maintain satisfactory performances over their service life. When multiplied by the number of years that the sustainment is planned to be undertaken, the contracting cost is high. Many business processes are established to govern these asset sustainment activities and eventually become the source of inefficiency. This paper analyses the performance of these processes using a performance driven approach. Combined with input data of requests for engineering change in similar assets, this paper evaluates a new business process redesigned from an existing process to achieve significant savings in total cost of ownership as well as improving other non-financial performance indicators.

诸如建筑物，基础设施和国防系统之类的主要资产是长期投资，需要许多外包维持活动才能在其使用寿命内保持令人满意的性能。如果乘以计划进行维持的年数，则订约成本很高。建立了许多业务流程来管理这些资产维持活动，并最终导致效率低下。本文使用性能驱动的方法来分析这些过程的性能。结合类似资产工程变更请求的输入数据，本文评估了从现有流程重新设计的新业务流程，以实现总体拥有成本的显着节省以及改进其他非财务绩效指标。
