Cost estimation in software engineering is typically concerned with the financial spend on the effort to develop and test the software, this can also include requirements review, maintenance, training, managing and buying extra equipment, servers and software. Many methods have been developed for estimating software costs for a given project.
Project Cost Management (PCM) is the dimension of project management which aims to ensure that a project is completed within its approved budget. [1] [2] It encompasses several specific project management activities including estimating, job controls, field data collection, scheduling, accounting and design, and uses technology to measure cost and productivity through the full life-cycle of ...
Cost engineering is "the engineering practice devoted to the management of project cost, involving such activities as estimating, cost control, cost forecasting, investment appraisal and risk analysis". [1] "Cost Engineers budget, plan and monitor investment projects. They seek the optimum balance between cost, quality and time requirements." [2]
In the mid-2000s, there was some discussion of whether PCM (sometimes referred to as Enterprise Cost Management) would become a separate software category or be part of one or more of the existing enterprise software categories of enterprise resource planning (ERP), product lifecycle management (PLM), or supply chain management (SCM). The ...
Computer-aided process planning initially evolved as a means to electronically store a process plan once it was created, retrieve it, modify it for a new part and print the plan. Other capabilities were table-driven cost and standard estimating systems, for sales representatives to create customer quotations and estimate delivery time.
Total cost management (TCM) is the name given by AACE International to a process for applying the skills and knowledge of cost engineering. It is also the first integrated process or methodology for portfolio, program and project management. It was initially conceived by Thomas D. Fromm and John Nunnemaker of Perkins & Will, architects, in 1990 ...
Artemis combined project planning and scheduling with cost control and resource management. The first products were sold as turn-key systems: both hardware (the Hewlett Packard 21 series) and software built into a desk. In the early 1980s Metier launched a software-only version of Artemis for IBM mainframes.
On a real project, the actual activities that will be done in the context of a process must be shown to support the objectives. These activities are defined by the project planners as part of the Planning process. This objective-based nature of DO-178C allows a great deal of flexibility in regard to following different styles of software life ...
