摘要

我们提出了一种评估需求稳定性的新方法，作为构建更稳定的长寿命系统的贡献。基于目标的模型用于分析由系统可能的未来环境的场景所描述的许多可能的未来世界中的需求。结果是对需求和假设的可能不稳定性的评估，它可以呈现给系统开发人员，以告知可选的需求定义和支持“针对变化的目标设计”的架构选择。本文描述了执行分析的过程，并概述了实用工具支持。报告了工业规模的实际案例研究结果，验证了该方法、过程和工具的支持，并讨论了概念、过程和工具的可能发展。

Requirements stability assessment using scenarios

We present a new approach to assessing requirements stability as a contribution to the building of more stable long lifetime systems. A goal-based model is used to analyze the requirements in a number of possible future worlds described by scenarios of the possible future environment of the system. The result is an assessment of possible instability of the requirements and the assumptions, which can be presented to system developers to inform alternative requirements definition and architectural choices supporting 'targeted design for change'. A process for carrying out the analysis is described and practical tool support outlined. Results from an industrial scale, live case study validating the approach, process and tool support is reported, and possible developments of the concept, process and tool are discussed.
