COCOMO is the world's most widely used software estimation model.
Costar is a software estimation tool based on the Constructive Cost Model (COCOMO) described by Barry Boehm in his books Software Engineering Economics and Software Cost Estimation with COCOMO II.
Software project managers use Costar to produce estimates of a project's duration, staffing levels, effort, and cost. Costar lets you make trade-offs and experiment with "what-if" analyses to arrive at the optimal project plan.
