摘要：In this paper we calculate the cost of software product using Empirical study. Early prediction of software cost andquality is important for better software planning and controlling. In early development phases, design complexity metrics areconsidered as useful indicators of software testing effort and some quality attributes. Although many studies investigate therelationship between design complexity and cost and quality, it is unclear what we have learned from these studies, because nosystematic synthesis exists to date. Referring to the famous statement of Tom DeMarco , “You cannot control what you cannotmeasure”. Quality Measurements are – as in any other engineering discipline – also in software engineering a cornerstone for bothimproving the engineering process and software products. Quality Measurement not only helps to visualize the abstraction ofsoftware development process and product but also provide an infrastructure to perform comparison, assessment and prediction ofsoftware development artifacts. The large part of software measurements is to, in one way or another, measure or estimate softwarecomplexity and quality due to its importance in practices and research. The relationship between cognitive complexity andsoftware external quality depends on comprehending ability of software developer, tester or maintainer. This factor is notdeterministic and hence, cannot be investigated any other ways than empirically. In order to improve quality an organization musttake into account the costs associated with achieving quality since the objective of continuous improvement programs is not onlyto meet customer requirements, but also to do it at the lowest cost. This can only happen by reducing the costs needed to achievequality, and the reduction of these costs is only possible if they are identified and measured. Therefore, measuring and reportingthe cost of quality (CoQ) should be considered an important issue for managers. Risk management is the identification,assessment, and prioritization of risks followed by coordinated and economical application of resources to minimize, monitor, andcontrol the probability and/or impact of unfortunate event or to maximize the realization of opportunities. Risk management’sobjective is to assure uncertainty does not deviate the endeavour from the business goals.
