John Morgan02b Technical Research Paper30 March 2014COCOMOSummary | Introduction: Estimating the cost of software projects is inherently difficult. Cost estimating is standard in every business and industry. Many industries are unable to accurately estimate manufacturing or service costs, software development is not one of these industries. Due to continuous changes in the software application domain, personnel and stakeholders, cost estimation becomes one of the most difficult problems in software development. While it may seem like a simple task to estimate the cost of a software project, it is actually very challenging and difficult. COCOMO stands for Constructive Cost Model, an algorithm that helps predict the cost of software projects [4].Summary | History: Barry Boehm is a professor of computer science and software engineering at USC. Boehm is the creator of many advances in software engineering including, but not limited to, MBASE, Spiral, Theory W, and COCOMO. In 1981 Boehm published a book entitled "Software Engineering Economics", in which COCOMO was introduced and described for the first time. COCOMO-I was created to improve financial decisions made regarding software projects. After its initial public presentation, COCOMO-I has become a popular basis for cost estimation models [2]. Boehm researched and discovered trends in previous software projects, using the results as the basis for estimation modeling. At the time, Boehm worked for TRW where he led many evolutions in software productivity tools. COCOMO was one of those evolutions, but with the evolution of new and improved tools COCOMO-I started to lose its power and COCOMO-II was created [2]. This new version of the original COCOMO has paved the way… in the middle of the paper… to the maturity of the COCOMO II effort estimation software process from the CMMI perspective,” Research, Innovation and Vision for the Future, 2008.
