场景被认为是理解环境和系统之间接口的重要策略，也是引出和指定软件行为的一种手段。我们采用更广阔的视角来看待各种情况。对我们来说，场景是对环境中各种情况的不断发展的描述。我们的建议是由Leite在面向客户的需求基线上的工作构成的，该基线旨在为软件系统及其演变的外部需求建模。根据软件系统外部执行的主要操作，场景首先描述环境情况。场景还有助于澄清功能需求和非功能需求之间的相互关系。我们在案例研究的基础上验证了我们的策略和相关陈述。
Scenarios are well recognised as an important strategy towards understanding the interface between the environment and the system as well as a means of eliciting and specifying software behaviour. We adopt a broader view of scenarios. For us, a scenario is an evolving description of situations in the environment. Our proposal is framed by Leite’s work on a client-oriented requirements baseline, which aims to model the external requirements of a software system and its evolution. Scenarios start by describing the environment situations, according to the main actions performed outside the software system. Scenarios also help to clarify the interrelation between functional and non-functional requirements. We have validated our strategy and the related representations based on case studies.
