Traditional costing models for new systems and new buildings in industry, defence or government, have tended to focus on the costs of acquisition and implementation, with scant regard for the costs of running the system or decommissioning after use. The pressure to minimize expenditure and provide value for money from reduced resources means that complex projects have to encompass a wide range of often conflicting issues and interests. Systems Lifecycle Cost-Effectiveness shows how to manage the difficulties that can arise. Optimizing the system lifecycle cost-effectiveness is complex and influenced by many factors. Massimo Pica presents a variety of models for calculating cost, benefits and risk in projects, and explains how the human factors associated with a system's design and consequent value are as important as the technical costs associated with its construction or creation. This comprehensive text can be used by students, experienced system engineers, cost analysts and managers to improve their understanding of the wide range of issues involved in the evaluation of system life cycle cost-effectiveness.
