SystemStar Software Estimation Tool based on COCOMO II and COSYSMO 2, from Softstar Systems

Introduction to SystemStar

SystemStar implements two types of models:

COCOMO -- Software Cost Estimation
COSYSMO -- Systems Engineering Cost Estimation

SystemStar is a cost estimation tool based on the Constructive Cost Model (COCOMO®) created by Dr. Barry Boehm and the Constructive Systems Engineering Model (COSYSMO) created by Dr. Ricardo Valerdi. Engineers use SystemStar to produce estimates of a project's cost. SystemStar lets you make trade-offs and experiment with "what-if" analyses to arrive at a satisfactory project plan.

We plan to implement the COCOMO III and COSYSMO 3.0 models as soon as they are completed.

COCOMO

COCOMO is the world's most widely used software estimation model.

Software project managers use SystemStar to produce estimates of a project's duration, staffing levels, effort, and cost. SystemStar lets you make trade-offs and experiment with "what-if" analyses to arrive at the optimal project plan.

COCOMO is described by Barry Boehm in his books Software Engineering Economics and Software Cost Estimation with COCOMO II.

COCOMO has continued to evolve and improve since its introduction. Read a brief history of COCOMO for a summary.

SystemStar supports the traditional COCOMO, and the most recent models:

COSYSMO

SystemStar supports the original COSYSMO model and the latest COSYSMO 2.0 model.

COSYSMO is described in Dr. Valerdi's dissertation The Constructive Systems Engineering Cost Model (COSYSMO), which is installed with the SystemStar demo.

Looking for Costar?

Costar was our original COCOMO tool.

Costar has been largely superseded by SystemStar, which has more features, and implements more estimating models.
