The answer is that COCOMO II parameters can be viewed as two sets of parameters.

If this is a case for you, you might be intrigued how COCOMO II adjustment parameters fit into this picture.

Many project managers used to negotiate project costs with trade-off triangle and trade-off matrix in terms of product functionality, quality, and schedule. You can see scaling factors descriptions in Appendix B.

Model-driven adjustment of scaling factor “ b” is new in COCOMO II model and reflects latest trends in software engineering. See Appendix A for COCOMO II list of adjustment factors that affect first parameter. As the result of adjustment, “ a” coefficient value falls between 0.056 – 120. COCOMO II provides classification of factors that can have an influence on project cost, and lets you make better approximation of coefficients and scaling factors for your particular project. In practice, COCOMO parameters can be greatly different from its typical values.

Interestingly, project duration in COCOMO is approximately cube root of effort (in person-months). There are similar COCOMO formulas for project duration (expressed in months) and average size of project team. Where coefficient a is about 3 (2.94), and scaling factor b is close to 1 (1.0997).

The estimation formulas have the form:Ĭopy Code Effort (in person-months) = a x KSLOCb In general, COCOMO II estimates project cost, derived directly from person-months effort, by assuming the cost is basically dependent on total physical size of all project files, expressed in thousands single lines of code (KSLOC). Provides about 20% cost and 70% time estimate accuracy.The model is by now invigorative software engineering artifact that has, from customer perspective, the following features:
#Cocomo model for project provider software update#
The COCOMO II 1) model is a COCOMO 81 update to address software development practices in the 1990's and 2000's. It was developed initially (COCOMO 81) by Barry Boehm in the early eighties 2). Introduction to COCOMO II EstimatesĬOCOMO (Constructive Cost Model) is a model that allows software project managers to estimate project cost and duration. As in many projects, the next important step is to make cost estimates. Said above is a short scope definition for the project provided by the company.
