The Constructive Cost Model (COCOMO) is an algorithmic software cost estimation model developed by Barry Boehm. This model is based upon the non linear reuse formula

This model is based upon the linear reuse formula. It provides estimates that represent one standard deviation around the most likely estimate. It provides estimates pf effort and schedule. It is also called as Basic COCOMO….Difference between COCOMO 1 and COCOMO 2: COCOMO I What is the difference between Cocomo and Cocomo II? The project should save the results of this COCOMO calculation if needed to support its make or buy decision. The Constructive Cost Model (COCOMO) computation is used to estimate the level of effort needed to produce a given quantity of code. Example 2 is just for those teams who are aware of the KLOC and who needs a measurement against it. of defects/KLOC = 30/15 = 0.5 = Density is 1 Defect for every 2 KLOC. How is Cocomo model calculated?īasic COCOMO Model: Formula E=ab (KLOC or KDSI) b b D=cb(E) d b P=E/D where E is the effort applied in person-months, D is the development time in chronological months, KLOC / KDSI is the estimated number of delivered lines of code for the project (expressed in thousands), and P is the number of people required.

The estimated effort and scheduled time are given by the relationship as follows. It is good for a quick estimate of the cost. What is the advantage of COCOMO model?ĬOCOMO model provides an accurate size of the project parameters. It is the model that allows one to estimate the cost, effort and schedule when planning a new software development activity. What is COCOMO 2 model in software engineering?ĬOCOMO-II is the revised version of the original Cocomo (Constructive Cost Model) and is developed at University of Southern California. In COCOMO, projects are categorized into three types: Semidetached. How many types of COCOMO models are there? The model parameters are derived from fitting a regression formula using data from historical projects (63 projects for COCOMO 81 and 163 projects for COCOMO II). The Constructive Cost Model (COCOMO) is a procedural software cost estimation model developed by Barry W.
