By not presenting CoQ separately, it is difficult to identify and analyze these costs of quality. Improved presentation of the components of CoSQ in the inclusive model, targeted at the software industry, presents separately management's share in the costs of failure of control in addition to management's share in the costs of appraisal and control. This model demonstrates that by defining the optimal level of managerial appraisal and quality control costs, one can reduce the total management-based costs of software quality to a minimum. The article concludes with a discussion of the difficulties involved in the collection of cost of quality data, particularly data on managerial activities, and outlines the framework of activities for implementation of the inclusive CoSQ model. 收起
