These 15 values are then multiplied to calculate the EAF (Effort Adjustment Factor).

Then, depending on these ratings, appropriate cost driver values are taken from the above table. The project manager is to rate these 15 different parameters for a particular project on a scale of one to three.

Application of software engineering methods.The volatility of the virtual machine environment.These factors are known as Cost Drivers and the Intermediate Model utilizes 15 such drivers for cost estimation.Ĭlassification of Cost Drivers and their attributes: For that, various other factors such as reliability, experience, Capability. However, in reality, no system’s effort and schedule can be solely calculated on the basis of Lines of Code.
Cocomo model impact on project management code#
The basic Cocomo model assumes that the effort is only a function of the number of lines of code and some constants evaluated according to the different software system. The development time is measured in Months. The effort is measured in Person-Months and as evident from the formula is dependent on Kilo-Lines of code. The constant values a,b,c and d for the Basic Model for the different categories of system: Software Projects a b c d Organic 2.4 1.05 2.5 0.38 Semi Detached 3.0 1.12 2.5 0.35 Embedded 3.6 1.20 2.5 0.32 The above formula is used for the cost estimation of for the basic COCOMO model, and also is used in the subsequent models. 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. Embedded – A software project with requiring the highest level of complexity, creativity, and experience requirement fall under this category.

Eg: Compilers or different Embedded Systems can be considered of Semi-Detached type.

The projects classified as Semi-Detached are comparatively less familiar and difficult to develop compared to the organic ones and require more experience and better guidance and creativity.
