Development begins with the requirements assigned to the software. Basic COCOMO Model: Example E.g.1: Suppose that a project was estimated to be 400 KLOC. Effort equation’s exponent is determined by 5 scale factors. Effort equation’s exponent is determined by 3 development modes. This model is also based upon reuse model which looks at effort needed to understand and estimate. This model is based upon the non linear reuse formula This model is also based upon the assumption of reasonably stable requirements. This model is based upon the linear reuse formula. It provides estimates that represent one standard deviation around the most likely estimate.
It provides estimates pf effort and schedule. COCOMO II is useful in non-sequential, rapid development and reuse models of software.
§ The basic COCOMO81 model is a single-valued, static model that computes software development effort (and cost) as a function of program size expressed in estimated thousand delivered source instructions (KDSI).

Boehm proposed three levels of the model: basic, intermediate, detailed.
