These formulas are used as such in the Basic Model calculations, as not much consideration of different factors such as reliability, expertise is taken into account, henceforth the estimate is rough.

The constant values a and b for the Basic Model for the different categories of system: Software Projects a b Organic 2.4 1.05 Semi Detached 3.0 1.12 Embedded 3.6 1.20 The effort is measured in Person-Months and as evident from the formula is dependent on Kilo-Lines of code.

Basic Model – 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.

It was proposed by Barry Boehm in 1970 and is based on the study of 63 projects, which make it one of the best-documented models. It is a procedural cost estimate model for software projects and often used as a process of reliably predicting the various parameters associated with making a project such as size, effort, cost, time and quality. The model parameters are derived from fitting a regression formula using data from historical projects (61 projects for COCOMO 81 and 163 projects for COCOMO II).Ĭocomo (Constructive Cost Model) is a regression model based on LOC, i.e number of Lines of Code. The Constructive Cost Model (COCOMO) is a procedural software cost estimation model developed by Barry W.
