介绍了系统工程在应用时裁剪的必要步骤，包括组织级和项目级的两级裁剪，指出了一种贴合实际的裁剪策略，即可先剪掉不必要的过程、活动和任务，然后再裁出适合自身需要的过程体系。归纳了剪裁时常用的方法和应当避开的常犯错误和陷阱，然后用一组不同领域的系统工程应用案例阐明了应用和裁剪的各自重点。

This paper briefly introduced the necessary steps of tailoring during the application of systems engineering. There are two levels of tailoring:organization-level tailoring and project-level tailoring. A practical tailoring strategy is proposed, cutting unnecessary processes/activities and tasks at first, then adjusting or calibrating in accordance with precise needs. On the basis of references of mature methods, some mistakes and traps are listed to be avoided. At last, in the light of tailoring strategies, a series of domain cases are analyzed from the view of systems engineering application. These research results could be reference for the proper application of systems engineering in the new domains.
