Box Cocomo Basic Effort Formula

Effort (E) = ax (Size)b where and b = constants derived from regression analysis (depends on the projectja Size = thousands of lines of code (KLOC) E = effort expressed in staff-months

As pointed out by Dr. Frailey, effort is measured in staff-months (19 days per month or 152 working hours per month), the constants a and b can be determined by a curve fit procedure (regression analysis), matching project data to the equation. Most organizations do not have enough data to perform such an analysis and begin by using Boehm's three levels of difficulty that seem to characterize many software projects. Box 11 ?2 shows the basic formulas; Table 11 -2 lists the effort and development time formulas for each mode.
