验证是系统工程的一个重要方面。验证活动提供了证据，证明正在开发的系统执行了预期的操作。在采购计划中，核查活动提供合同履行的证据。事实上，系统开发的一大部分资金用于设计和执行核查战略。然而，在目前的实践中，核查战略的设计往往是由标准规定的，并由良好做法和直觉驱动。设计验证策略的定量方法可以显着提高其有效性和覆盖范围。要实现这种转变，就必须了解核查如何有助于系统的预期效用。本文提出了四个关键属性的效用验证：从认识论的角度来看，验证的意义;在系统开发的数学框架内的验证表示;验证活动的价值的耦合性质;和客观评价验证的不可能性。
Verification is an essential aspect of systems engineering. Verification activities provide evidence that the system under development does what it was anticipated to do. In acquisition programs, verification activities provide evidence of contractual fulfilment. In fact, a major financial portion of system development is spent towards designing and executing a verification strategy. However, the design of verification strategies in current practice is often prescribed by standards and driven by good practices and gut feeling. Quantitative approaches to design verification strategies could yield significant improvement to their effectiveness and coverage. Understanding how verification contributes to a system's expected utility is necessary to enable such transformation. This paper presents four key properties of the utility of verification: the meaning of verification from an epistemological standpoint; the representation of verification within a mathematical framework of system development; the coupled nature of the value of verification activities; and the impossibility of objectively valuing verification.
