Cost estimation models are mathematical algorithms or parametric equations used to estimate the costs of a product or project. The results of the models are typically necessary to obtain approval to proceed, and are factored into business plans, budgets, and other financial planning and tracking mechanisms.
Closely related software parametric models are Constructive Cost Model , Parametric Review of Information for Costing and Evaluation – Software (PRICE-S), and Software Evaluation and Estimation of Resources – Software Estimating Model . A claimed advantage to this model is the simplicity of calibration.
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.
Activity-based costing was later explained in 1999 by Peter F. Drucker in the book Management Challenges of the 21st Century. [11] He states that traditional cost accounting focuses on what it costs to do something , for example, to cut a screw thread; activity-based costing also records the cost of not doing , such as the cost of waiting for a ...
Techno-economic assessment or techno-economic analysis (abbreviated TEA) is a method of analyzing the economic performance of an industrial process, product, or service. The methodology originates from earlier work on combining technical, economic and risk assessments for chemical production processes. [ 1 ]
Associations, considered non-profit organizations--one example, is AACE International "is dedicated to the tenets of furthering the concepts of Total Cost Management and Cost Engineering. Total Cost Management is the effective application of professional and technical expertise to plan and control resources, costs, profitability and risk.
Intermediate COCOMO computes software development effort as function of program size and a set of "cost drivers" that include subjective assessment of product, hardware, personnel and project attributes. This extension considers a set of four "cost drivers", each with a number of subsidiary attributes:-
Originally a division of RCA and later a strategic business unit of Lockheed Martin, PRICE Systems is considered the pioneer in the science of parametric modeling because the PRICE parametric models were the first generally available computerized cost estimation software. [4] PRICE became an independent, privately held company in 1998.
