研究发现，修改有缺陷的需求、设计和代码通常会消耗软件开发总成本的50%。当缺陷被插入到设计中并且只在项目的后期阶段被检测到时，它会产生很大的影响。这增加了项目成本和时间，甚至可能危及项目的成功。需要花费更多的时间来分析该项目的设计。当分析技术应用于软件系统的设计时，主要目标是预测系统中潜在的故障场景。在软件生命周期的早期阶段，检测可能导致失败的缺陷并进行纠正更具成本效益，而测试开始较晚，并且在测试期间发现的缺陷可能需要大量返工。在本文中，我们提出了一个度量套件，用于指导故障模式风险评估过程中的分析。度量集的计算基于Simulink模型。我们为此活动提供工具支持。
Studies have found that reworking defective requirements, design, and code typically consumes up to 50 percent of the total cost of software development. A defect has a high impact when it has been inserted in the design and is only detected in a later phase of a project. This increases project cost, time and may even jeopardize the success of a project. More time needs to be spent on analysis of the design of the project. When analysis techniques are applied on the design of a software system, the primary objective is to anticipate potential scenarios of failure in the system. The detection of defects that may cause failures and the correction is more cost effective in the early phases of the software lifecycle, whereas testing starts late and defects found during testing may require massive rework. In this article, we present a metric suite that guides the analysis during the risk assessment of failure modes. The computation of the metric suite bases on Simulink models. We provide tool support for this activity.
