A parametric model is a set of related mathematical equations that incorporates variable parameters. A scenario is defined by selecting a value for each parameter. Software project managers use software parametric models and parametric estimation tools to estimate their projects' duration, staffing and cost.
In project management (e.g., for engineering), accurate estimates are the basis of sound project planning. Many processes have been developed to aid engineers in making accurate estimates, such as Analogy based estimation; Compartmentalization (i.e., breakdown of tasks) Cost estimate; Delphi method; Documenting estimation results; Educated ...
According to the PMBOK (7th edition) by the Project Management Institute (PMI), Estimate at completion (EAC) is the "expected total cost of completing all work expressed as the sum of the actual cost to date and the estimate to complete."
Models typically function through the input of parameters that describe the attributes of the product or project in question, and possibly physical resource requirements. The model then provides as output various resources requirements in cost and time. Some models concentrate only on estimating project costs (often a single monetary value).
Earned Value Management is a second tool within project management that allows for the tracking of progress throughout the life cycle of a project. BOEs, when executed properly and with the aid of certain software packages, allow for a seamless transition from project proposal to execution by transferring data from the BOE directly into ...
Formal estimation model: The quantification step is based on mechanical processes, e.g., the use of a formula derived from historical data. Combination-based estimation: The quantification step is based on a judgmental and mechanical combination of estimates from different sources. Below are examples of estimation approaches within each category.
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 ...
Estimation (or estimating) is the process of finding an estimate or approximation, which is a value that is usable for some purpose even if input data may be incomplete, uncertain, or unstable. The value is nonetheless usable because it is derived from the best information available. [ 1 ]
