COCOMO Project Homepage - The COCOMO II model is an update of COCOMO 1981 to address software development practices in the 1990s and 2000s. It is being developed and continually enhanced by USC-CSE, UC Irvine, and 29 affiliate organizations. A public version of COCOMO II is available, including a Java implementation.
CoolSoft - COOLSoft utilizes a hybrid approach of intermediate and detailed versions of the Constructive Cost Model (COCOMO). This allows for the reuse of existing code, development of new code, the purchase and integration of third party code, and hardware integration. The output is then displayed as man-months of programming effort, calendar schedule, support costs and hardware costs.
Cost Xpert - Cost Xpert stands for innovation transferred into measurable and lasting value creation, with a short amortization time and high customer satisfaction.
Costar Software Estimation Tool - Costar is a software cost estimation tool based on COCOMO II. A software project manager can use Costar to produce estimates of a project's duration, staffing levels, effort, and cost. Costar is an interactive tool that permits managers to make trade-offs and experiment with what-if analyses to arrive at the optimal project plan.
East Tennessee State University -- COSMOS - This software project estimation and analysis tool gives project managers insight into the size, effort, and schedule of their software development project. This tool is unique in that it combines the well-known Function Point and COCOMO models as well as a Rayleigh model of staff buildup proposed by Lawrence Putnam. These three models can be used independently or work together. With COSMOS, users can gain an understanding of changes in project requirements and resources that impact the project's size, effort, and schedule. Furthermore, COSMOS is ideal for helping educators provide students with insight into how the function point and COCOMO models work.
SPAWAR SEPO Reference Page - SEPO has made available a list of sites for estimation tools and other information, including version 9.2 of the Revised Intermediate COCOMO Model (REVIC), which is sponsored by the Air Force Cost Analysis Agency.
