The Lawrence Putnam model describes the time and effort requires finishing a software project of a specified size. Full form of COCOMO is COnstructive COst estimation Model. COCOMO is a heuristic cost estimation technique. In communications theory, to model multiple paths of dense scattered signals reaching a receiver.Table 2:Basic model coefficient Software project a b c Organic 2.4 1.05 0.38 Semi-detached 3.0 1.12 0.35 Embedded 3.6 1.20 0.32 b)Intermediate COCOMO In this model, software development effort is stated as function of size, program, and a collection of 15 cost stimulations including subjective evaluation of the product, hardware. Cocomo (Constructive Cost Model) is a regression model based on LOC, i.e number of Lines of Code.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 … COCOMO model is a regression model. In the physical sciences to model wind speed, wave heights and sound/light radiation.Putnam makes a use of a so-called The Norden/Rayleigh Curve to estimate project effort, schedule & defect rate as shown in fig: Putnam noticed that software staffing profiles followed the well known Rayleigh distribution. Project Scheduling Definition of COCOMO in the dictionary.

The constructive cost model (COCOMO) is one of the most widely used software cost estimation models. Long history from initial version published in 1981 (COCOMO-81) through various instantiations to COCOMO 2 COCOMO 2 takes incorporates a range of sub-models that produce increasingly detailed software estimates such as the early design model, reuse model, etc 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 … This is often not the case. COCOMO-II is the revised version of the original Cocomo (Constructive Cost Model) and is developed at University of Southern California. This model is developed by B.W.Boehm in 1981. (1998) Software Project Management: A Unified Framework, Addison Wesley Center for Software Engineering, USC (1999) COCOMO II Model Definition Manual. By using COCOMO you can calculate the amount of … (1998) Software Engineering: Theory and Practice, Prentice Hall Royce, W.

The specific version utilized here is the “basic” model.
