Can be used for making investment or other financial decisions involving software development, setting project budgets and schedules as a basis for planning and control, and making general software cost and schedule risk management decisions. Originally established 1981, it includes three sub-models each offering further fidelity, called Applications Composition, Early Design, and Post-Architecture.

After several years and the combined efforts of USC-CSSE, ISR at UC Irvine, and the COCOMO® II Project Affiliate Organizations, the result is COCOMO® II, a revised cost estimation model reflecting the changes in professional software development practice that have come about since the 1970s.ĭetails of the COCOMO® II model, such as the input parameter definitions, the model form, and how the model was calibrated, can be found in the book Software Cost Estimation with COCOMO II.A model that facilitates estimation of cost, effort and schedule when planning a new software development activity. The solution to the problem was to reinvent the model for the 1990s. These changes and others began to make applying the original COCOMO® model problematic. These changes included a move away from mainframe overnight batch processing to desktop-based real-time turnaround a greatly increased emphasis on reusing existing software and building new systems using off-the-shelf software components and spending as much effort to design and manage the software development process as was once spent creating the software product. In the ensuing decade and a half, software development techniques changed dramatically. Barry Boehm in 1981, and reflected the software development practices of the day.

Listed in increasing input parameters and accuracy, these submodels are called the Applications Composition, Early Design, and Post-architecture models.ĬOCOMO® II can be used for the following major decision situations: It consists of three submodels, each one offering increased accuracy the further along one is in the project planning and design process.

COCOMO® II is the latest major extension to the original COCOMO® (also known as COCOMO® 81) model published in 1981. The COnstructive COst MOdel II (COCOMO® II) is a software cost, effort, and schedule model.
