#WHAT IS COCOMO MODEL IN SOFTWARE ENGINEERING DRIVERS#
Here we discuss only cost drivers personnel attributes :.There are four types of cost drivers :.The Six phases of detailed COCOMO are: Planning and requirements System design Detailed design.Software Engineering | COCOMO Model - GeeksforGeeks.The first level, Basic COCOMO is good for quick, early, rough order of magnitude estimates of software costs, but its accuracy is limited due to its lack of factors to account for difference in project attributes ( Cost Drivers ). In 1995 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. These projects were based on the waterfall model of software development which was the prevalent software development process in 1981. It estimates the required number of Man-Months (MM) for the full development of software products. The COCOMO estimates the cost for software product development in terms of effort (resources required to complete the project work) and schedule (time required to complete the project work) based on the size of the software product. How does Cocomo estimate the cost for software product development? Intermediate COCOMO computes software development effort as function of program size and a set of "cost drivers" that include subjective assessment of product, hardware, personnel and project attributes. Last one is Complete COCOMO model which is short coming of both basic & intermediate.
