These two models are further discussed below.
Intermediate COCOMO takes these Cost Drivers into account and Detailed COCOMO additionally accounts for the influence of individual project phases, i.e in case of Detailed it accounts for both these cost drivers and also calculations are performed phase wise henceforth producing a more accurate result. Its accuracy is somewhat restricted due to the absence of sufficient factor considerations. The first level, Basic COCOMO can be used for quick and slightly rough calculations of Software Costs. Any of the three forms can be adopted according to our requirements. Types of Models: COCOMO consists of a hierarchy of three increasingly detailed and accurate forms. Such software requires a larger team size than the other two models and also the developers need to be sufficiently experienced and creative to develop such complex models.Īll the above system types utilize different values of the constants used in Effort Calculations.
