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.
Software researchers and practitioners have been addressing the problems of effort estimation for software development projects since at least the 1960s; see, e.g., work by Farr [8] [9] and Nelson. [10] Most of the research has focused on the construction of formal software effort estimation models.
A cost estimate is often used to establish a budget as the cost constraint for a project or operation. In project management, project cost management is a major functional division. Cost estimating is one of three activities performed in project cost management. [3] In cost engineering, cost estimation is a basic activity. A cost engineering ...
Basis of estimate (BOE) is a tool used in the field of project management by which members of the project team, usually estimators, project managers, or cost analysts, calculate the total cost of the project.
B is a scaling factor and is a function of the project size. [3] Productivity is the Process Productivity, the ability of a particular software organization to produce software of a given size at a particular defect rate. Effort is the total effort applied to the project in person-years. Time is the total schedule of the project in years.
[19] [20] At this point the cost to scrap the project and develop a new one was estimated to be SEK 11bn ($1.3bn). Not seen as an alternative, the development continued and the original budget of SEK 2.4bn was increased to 4bn. [21] In 2015 the project was still on its way to be fully implemented. SEK 4bn ($470m) [22] (ongoing)
Analogous Estimating: Using the cost of similar project to determine the cost of the current project; Determining Resource Cost rates: The cost of goods and labor by unit gathered through estimates or estimation. Bottom Up estimating: Using the lowest level of work package detail and summarizing the cost associated with it.
COCOMO II is the successor of COCOMO 81 and is claimed to be better suited for estimating modern software development projects; providing support for more recent software development processes and was tuned using a larger database of 161 projects. The need for the new model came as software development technology moved from mainframe and ...
