系统验证、确认和测试（VVT）是系统工程领域内的基本活动，需要在交付或销售产品之前进行;但为了确保产品以最佳方式符合客户和工程要求，所有这三项活动都应在整个产品项目生命周期中实施。VVT的主要目标是确保客户收到优质产品，并且客户和供应商都不会因交付后的产品故障而承担返工成本。文献包括很少的研究有效地关联VVT方法VVT活动，并考虑到项目的限制，如成本，风险和进度。在我们以前的研究中，我们开发了一个分析模型，在给定的项目约束条件下，产生了一个最佳的VVT计划，并提供了一个恢复程序来管理VVT过程中的意外事件。该模型的使用演示了一个样本问题，包括一些不可预见的事件。在本文中，我们更进一步，并使用我们的模型来分析一个真实的工业项目。正如在案例研究中所预期的那样，该模型在整个案例实施过程中得到了进一步的发展;具体而言，开发了一种新的定量模型，用于评估VVT过程测试覆盖率的质量。项目经理发现模型输出对他的工作很有价值和信息量，因此热情地合作进行这个案例研究。除了案例研究的报告，我们还进行了三个焦点小组讨论，以获得见解，意见，态度和参与者的看法，建议的分析模型作为决策支持模型。
ABSTRACT System VVT (verification, validation, and testing) are essential activities within the domain of system engineering and need to be performed before delivering or marketing products; but to ensure the product complies with customer and engineering requirements in the best possible manner, all three activities should be implemented throughout the product project life cycle. The main objective of VVT is to ensure the customer receives a quality product and neither the customer nor the supplier is burdened with the cost of rework due to failures of the product after delivery. The literature includes very little research for effectively associating VVT methods to VVT activities and also taking into consideration project constraints such as cost, risk, and schedule. In our previous studies, we developed an analytical model that, given project constraints, produced an optimal VVT plan and provided a recovery procedure to manage unexpected events within the VVT process. The use of the model was demonstrated on a sample problem incorporating some unforeseen events. In this paper, we go one step further and use our model to analyse a real industrial project. As expected in a case study, the model has been further developed throughout the case implementation; specifically, a new quantitative model for assessing quality as a function of the test coverage of the VVT process was developed. The project manager found the model output valuable and informative to his work and thus enthusiastically collaborated on this case study research. Besides the report of the case study, we also conducted three focus group discussions to obtain insights, opinions, attitudes, and perceptions of the participants on the proposed analytical model as a decision support model.
