This model This model distinguishes three types of projects: organi c, semi-det ached and embedded [4]. The primary objectives of the COCOMO II effort are: • To develop a software cost and schedule estimation model tuned to the life cycle practices of the 1990's and 2000's. Maintenance, rework, porting, and reuse are issues that don't fit cleanly into the same model. It is an algorithmic approach to estimating the cost of a software project. It is a hierarchy of software cost estimation models, which includes Basic, Intermediate and Detailed sub models. The COCOMO 2 model in Software Engineering is tuned to modern software life cycles. The value of accuracy of the proposed model is 0.96 which clearly says the state of accuracy than other models. Simple COCOMO:- It was the first model suggested by Barry Boehm, which Follows following formula: Efforts= a*(KLOC) b Here a and b are complexity factor. . The main cocomo model advantage is that you can determine the costs that will be incurred when investing in a particular project. The leading method using this approach is COCOMO's detailed model. The COCOMO model was used to determine the exact volume of the planning objectives. c. It oversimplifies the impact of safety/security aspects. However, it doesn't apply to newer software development practices as . It examines different factors affecting the project costs. Advantages of COCOMO Model COCOMO is transparent, one can see how it works unlike other models such as SLIM Drivers are particularly helpful to the estimator to understand the impact of different factors that affect project costs. The following relationship gives the predicted efforts and timeframes. The COCOMO II model makes its estimates of required effort (measured in Person-Months � PM) based primarily on your estimate of the software project's size (as measured in thousands of SLOC, KSLOC)): Effort = 2.94 * EAF * (KSLOC)E. Where. 8. The detailed COCOMO'81 model incorporates all characteristics of the intermediate version with an assessment of the cost driver's impact on each step (analysis, design, etc. ) Has the effect of creating buy-in with employees at all levels about using competency management in the organization. The necessary steps in this model are: Get an initial estimate of the development effort from evaluation of thousands of delivered lines of source code (KDLOC). Better suited for large mission-critical projects. Advantages and Disadvantag es of COCOMO Model Advantages Easy to estimate the total cost of the project. This model can be classified into three categories basic, intermediate, and detailed sub-models. Uncategorized. DETAILED/ADVANCED COCOMO MODEL: A major shortcoming of both the basic and intermediate COCOMO models is that they consider a software product as a single homogeneous entity.
