Setting mixed investment strategies to improve organization's software capability, via reuse, tools, process maturity, outsourcing, etc. Making legacy software inventory decisions: what parts to modify, phase out, outsource, etc Making software cost and schedule risk management decisionsДeciding which parts of a software system to develop, reuse, lease, or purchase Setting project budgets and schedules as a basis for planning and controlДeciding on or negotiating tradeoffs among software cost, schedule, functionality, performance or quality factors Making investment or other financial decisions involving a software development effort It has new cost drivers, new line counting rules, and new equations.Д¬OCOMO II can be used for the following major decision situations You'll use it after you've developed your project's overall architecture. This is the most detailed COCOMO II model. Based on Unadjusted Function Points or KSLOC. It uses a small set of new Cost Drivers, and new estimating equations. You can use this model to get rough estimates of a project's cost and duration before you've determined it's entire architecture. Suitable for projects built with modern GUI-builder tools. COCOMO II targets modern software projects, and will continue to evolve over the next few years. The original COCOMO model has been very successful, but it doesn't apply to newer software development practices as well as it does to traditional practices. It provides more support for modern software development processes and an updated project database.Д¬OCOMO II is tuned to modern software life cycles. COCOMO II is the successor of COCOMO 81 and is better suited for estimating modern software development projects. In 1997 COCOMO II was developed and finally published in 2000 in the book Software Cost Estimation with COCOMO II. References to this model typically call it COCOMO 81. COCOMO was first published in 1981 Barry W. Function Point Table Number of FPs Complexity External user type Low Average High External input type 3 4 6 External output type 4 5 7 Logical internal file type 7 10 15 External interface file type 5 7 10 External inquiry type 3 4 6. The model uses a basic regression formula, with parameters that are derived from historical project data and current project characteristics. Software Architecture Example of COCOMO-II Ahmed E. The Constructive Cost Model (COCOMO) is an algorithmic software cost estimation model developed by Barry Boehm.
