This helps in determining the workforce allocation for each phase of the project.
The detailed model provides a set of phase-sensitive effort multipliers for each cost driver. The detailed model introduces two more capabilities that are as follows. It offers a medium to process all the project characteristics for calculating the software estimation.
ADVANCED COCOMO MODEL DRIVER
Then based on these three ratings, he suggests an appropriate cost driver value to be multiplied with the initial estimate that was obtained from the basic COCOMO model. Boehm requires the project manager to rate these fifteen different parameters for a particular project on a scale of one to three. This estimate is obtained through the basic COCOMO expressions with the help of a set of fifteen cost drivers, based on various attributes of software development. The basic COCOMO model assumes that effort is the only factor, which calculates the number of lines of code and constants with respect to the multiple software systems. When we calculate effort and development time, then the average staff size to complete the project should be calculated as. The accuracy of this model is considerably restricted because of the insufficient factor considerations. In this category, the larger team size is needed as compared to the previous models. It also requires better guidance, more experienced developers. The projects that come under the semi-detached are less familiar and hard to develop. In this type, team members have good experience and knowledge. This category is for the small to medium size software product. All the models are applied to different projects according to the requirements. It is measured in the unit of time, for example, months, and weeks. Schedule: The amount of time required to complete the work is directly proportional to the effort. Boehm in This model can be classified into three categories basic, intermediate, and detailed sub-models.
