【正文】 izational objectives, reconciling customer needs with product design has to consider quality in addition to functionality. For project managers testing supports risk management and progress estimation. The focus is on identifying and eliminating risks that are potential value breakers and inhibit value achievements. Early detection of severe defects that significantly reduce project performance is a major objective. Ideally, testing reduces uncertainty and helps project managers to take better, more informed decisions, ., for defect removal, system stabilization, and release decisions. Quality managers are interested in the identification of problems and in particular problem trends. Results from testing are the input for the assessment of development performance and provide the basis for quality assurance strategies and process improvement. Rosenberg (2003) discusses how testing contributes to quality assurance and shows that problems need to be documented, corrected, and can then be used for process improvement。 after assessing problem reports for their validity corrective actions are implemented in accordance with customerapproved solutions。 developers and users are informed about the problem status。 and data for measuring and predicting software quality and reliability is provided. Developers require feedback from testing to gain confidence that the implementation is plete and correct, conforming to standards, and satisfying quality requirements. For stabilization, testing provides details about defects and their estimated severity, information for reproducing defects, and support for revealing the cause of the failures. Besides, testing provides feedback for improvement and learning from defects. For example, throughout maintenance a detailed and reproducible description of problems contributes to the efficient implementation of changes and regression tests ensuring that these changes do not break existing functionality. For requirements engineers, testing is valuable to validate and verify requirements. Gause and Weinberg (1989) point out that “… one of the most effective ways of testing requirements is with test cases very much like those for testing a plete system.” Deriving blackbox tests from requirements helps to assure their pleteness, accuracy, clarity, and conciseness early on. Tests thus enhance requirements and enable development in a testdriven manner. To summarize, testing helps to realize benefits by reducing planning uncertainty, mitigating risks, making more informed decisions, controlling efforts, and minimizing downstream costs (the internal dimension).More importantly, it helps to realize the expected stakeholder value propositions (the external dimension). These benefits, however, do not e for free and the costs of testing are often significant. Testing can be perceived as buying information and can be considered as an investment activity as it reduces the costs of risks, uncertainties, and the reward of taking risks. Making sound decisions about the investment in testing requires understanding their implications on both costs and benefits. The underlying questions therefore are: What are the costs of testing, and what are the benefits of testing for value generating activities?11
