The Constructive Cost Model (COCOMO) is a procedural software cost estimation model developed by Barry W. Boehm. The model parameters are derived from fitting a regression formula using data from historical projects (63 projects for COCOMO 81 and 163 projects for COCOMO II).
Object points are an approach used in software development effort estimation under some models such as COCOMO II. [1] [2]Object points are a way of estimating effort size, similar to Source Lines Of Code (SLOC) or Function Points.
AFCAA REVIC is a set of programs for use in estimating the cost of software development projects. [1] The Revised Enhanced Version of Intermediate COCOMO (REVIC) model is a copyrighted program available for public distribution under agreement with the REVIC developer, Ray Kile, and the U.S. Air Force Cost Analysis Agency (AFCAA).
This score is then transformed into time by applying a statistical model called average programmer profile weights (APPW) which is a proprietary successor to COCOMO II 2000 and COSYSMO. The resulting time in programmer work hours is then multiplied by a user defined cost per hour of an average programmer, to produce an average project cost ...
The perhaps most common estimation methods today are the parametric estimation models COCOMO, SEER-SEM and SLIM. They have their basis in estimation research conducted in the 1970s and 1980s and are since then updated with new calibration data, with the last major release being COCOMO II in the year 2000.

Danette Colbert was charged with fraud after Adan Manzano’s death, and police say they have since heard from others who allege they or a loved one were also victims.
There are several cost, schedule, and effort estimation models which use SLOC as an input parameter, including the widely used Constructive Cost Model series of models by Barry Boehm et al., PRICE Systems True S and Galorath's SEER-SEM. While these models have shown good predictive power, they are only as good as the estimates (particularly the ...
