 COCOMO - Wikipedia, the free encyclopedia
COCOMO is a model designed by Barry Boehm to give an estimate of the number of man-months it will take to develop a software product.
Intermediate COCOMO - computes software development effort as function of program size and a set of "cost drivers" that include subjective assessment of product, hardware, personnel and project attributes.
Detailed COCOMO - incorporates all characteristics of the intermediate version with an assessment of the cost driver's impact on each step (analysis, design, etc.) of the software engineering process.

 Parametric Cost Estimating Handbook - REVIC   (Site not responding. Last check: 2007-10-31)
REVIC uses the intermediate COCOMO set of equations for calculating the effort (man-power in staff-months and staff-hours) and schedule (elapsed time in calendar months) to complete software development projects based on an estimate of the lines of code to be developed and a description of the development environment.
COCOMO provides a set of tables distributing the effort and schedule to the phases of development (system engineering, preliminary design, critical design, etc.) and activities (system analysis, coding, test planning, etc.) as a percentage of the total.
While REVIC processing is mostly the same as Intermediate COCOMO, it provides a single weighted "average" distribution for effort and schedule, along with the ability to allow the user to vary the percentages in the system engineering and DTandE phases.

 (Basic; Simple) COnstructive COst MOdel (COCOMO)
COCOMO assures that requirements will not change substantially, though some refinements and reinterpretations are inevitable.
The Intermediate model also produces better results than the Basic model because the system can be divided into "components".
COCOMO can estimate the staffing, cost, and duration of each of the components -- allowing you to experiment with different development strategies, to find the plan that best suits your needs and resources.

The Intermediate COCOMO is an extension of the Basic COCOMO to consider a set of "cost driver attributes" that can be grouped into four major categories, each with a number of subcategories:
Each of the 15 attributes is rated on a 6-point scale that ranges from "very low" to "extra high" (in importance or value).

The original COCOMO model was a set of models; 3 development modes (organic, semi-detached, and embedded) and 3 levels (basic, intermediate, and advanced).
Intermediate - predicted software size (lines of code), plus a set of 15 subjectively assessed 'cost drivers' was used to estimate development effort.
COCOMO starts from an estimate of size and uses subjective assessment of 15 (independent?) cost drivers (based on 63 datasets) to estimate effort.

Boehm's CoCoMo There are three forms of the COnstructive COst MOdel : Basic CoCoMo which gives an initial rough estimate of man months and development time, Intermediate CoCoMo which gives a more detailed estimate for small to medium sized projects, Detailled CoCoMo which gives a more detailed estimate for large projects.
Boehm claims estimates calculated using Basic CoCoMo are within a factor of 1.3 of the actual figures 29% of the time, and within a factor of 2.0 60% of the time.
Observations on CoCoMo: Documented results by Boehm when using CoCoMo have shown a high level of accuracy in producing cost estimates, however these were derived from completed projects at which stage exact figures were known for both the size, and other cost factors.

 COCOMO
COCOMO II is defined using intermediate calculations, but the COCOMO 81 models let you choose between the Intermediate mode and the Detailed mode.
In some of the later COCOMO models, a cost driver setting of Nominal may not correspond to an Effort Multiplier of 1.00, so you may have computed the effort incorrectly.
COCOMO II.1998 was renamed to COCOMO II.1999 and then to COCOMO II.2000, so all of those models are identical.

There are a number of different types: The Basic COCOMO Model estimates the effort required to develop software in three modes of development ({Organic Mode}, {Semidetached Mode}, or {Embedded Mode}) using only {DSI}s as an input.
The Intermediate model also allows the system to be divided and estimated in components.
The Detailed COCOMO Model differs from the Intermediate COCOMO model in that it uses effort multipliers for each phase of the project.
