COCOMO II includes the application co m position m odel ( f or earl y protot y ping e ff orts) and the m ore detailed Earl y Design and Post- Architecture m odels ( f or subsequent portions o f the li f e c y cle). Objecti v e of So f t w a re Cost E st i m at i on w ith COCOMO II The m ost f unda m ental calculation in the COCOMO II m odel is the use o f the e ff ort equation t o esti m ate the nu m ber o f person m onths required to develop a project. Most o f the other COCOMO II results including the esti m ates f or require m ents and m aintenance, are derived f ro m this quantit y. It is also connected to deter m ining how m uch e ff ort and ti m e a so f tware project requires. It establishes a f ir m, reliable budget f or an in house project.

Curves are then f it to the data points to get d escriptive equations which are the m odels. S m aIl Projects: 3,4 Measure m ents o f s m all to m oderate projects resulted in a m odel o f the f ollowing f or m: E FF O RT a S I Z E b (1).

It m eans that i f we tr y to develop a larger product, our productivit y ( S I Z E E FF O RT ) Decreases. This decrease in productivit y on larger projects is called a disecono my o f sc a le. The m ain reasons wh y larger so f tware products incur disecono m ies o f scale are the f ollowing: 1. Relativel y m ore product design is required to develop the thorough unit-level speci f ications required to support the parallel activit y o f a larger nu m ber o f progra mm ers. Relativel y m ore e ff ort is required to veri f y and validate the larger require m ents and design speci f ications.
