A “portfolio‐of‐systems” is a collection of systems related by common management and budgeting, and at least some relationship to mission or missions. A portfolio‐of‐systems describes the not uncommon situation where an office is responsible for multiple systems in multiple phases of development but those systems are not related by common design, common manufacturing, or necessarily interconnected operationally. The relationship is fundamentally one of management, although other linkages might be present or designed if such additional linkages are deemed beneficial. The portfolio‐of‐systems concept differs from systems‐of‐systems and product‐line or family‐of‐systems constructs. This paper describes generalizations of architecting techniques for portfolio situations, particularly recognizing the presence of many largely independent components in multiple stages of development with an ongoing or episodic process. The paper presents two case studies of actual portfolios: One a portfolio of operational demonstration systems and the other a portfolio of weather satellites.

设计系统组合

“系统组合”是一组由共同的管理和预算相关的系统，并且至少与某个或多个任务有某种关系。系统组合描述了一种情况，这种情况并不罕见，在这种情况下，办公室负责多个开发阶段的多个系统，但是这些系统与通用设计，通用制造或必不可少的业务互连无关。这种关系从根本上说是一种管理关系，尽管如果认为其他联系是有益的，则可能会存在或设计其他联系。系统组合的概念不同于系统系统和产品线或系统族构造。本文介绍了针对投资组合情况的架构技术的概括，特别是要认识到，在开发过程的多个阶段中，无论是持续进行的还是情节性的过程，都存在许多很大程度上独立的组件。本文介绍了两个有关实际项目组合的案例研究：一个是业务演示系统，另一个是气象卫星。
