Discuss cocomo model in cost estimation of the software in detail. Estimation by analogy remember btl1 i discuss albert function point analysis in detail10 ii illustrate the staffing pattern6 understand btl2 10 demonstrate the following i function point mark ii method8 ii cosmic full function point method8 apply btl3 11 explain the cocomo ii parametric productive model in detail16 analyze btl4. Remember btl -1 2 i what elements used in cocomo ii model 4 ii demonstrate the cocomo ii model? Explain in detail. Investigate the estimation accuracies of each model. Estimation technique: constructive cost model cocomo the cocomo model was also used to verify the estimate calculated by using the function point metric.
690 A sced rating of very low corresponds to an effort multiplier of 1. Semidetached, or embedded in the original cocomo model, and refine the four exponent-scaling factors in ada cocomo. Explain the component base software engineering and its advantages. It estimates or predicts the effort required for the project, total project cost and scheduled time for the project. V-model also referred to as the verification and validation model. Figure 1 shows the inputs to that model from kc-1: a nasa software project. Caveat: cocomo ii models are post-architectural best for construction phase. Cocomoconstructive cost model what purpose by boehm181. The basic cocomo81 model is a single-valued, static model that computes software development effort and cost as a function of program size expressed in. Than the other two cocomo i and ii models for a similar application for example task manager.
As an example of how the intermediate cocomo model works, the following is. 1046 Example: supposed that a project was estimated to be 400 kloc. It not only offers a cost estimation tools, but also provides a great amount of parameters which explain what the model is estimating and why it produces the. As an example, lets estimate how much effort and calendar time it would take to. Organic, semidetached and embedded software projects. The estimation model is useful for trade off between the developer and customer. Cocomo was first published in boehms 181 book software engineering economics1 as a model for estimating effort, cost, and schedule for software projects.
