Different project Modes/Types used in the Basic COCOMO 81

Basic COCOMO model: It estimates the software in a rough and quick manner. It mostly useful for the small medium sized software. There are three modes of development.

i. Organic

ii. Semi Detached

iii. Embedded

We used these three different modes of development to calculate the project effort, development time, average staff size, productivity according to different criteria which are shown below.

	ORGANIC	SEMI DETACHED	EMBEDDED
Size	2 50 KLOC	50 300 KLOC	300 & Above KLOC
Team Size	Small Size	Medium Size	Large Size
Developer Experience	Experienced Developers Needed	Average Experienced People	Very Little Previous experience
Environment	Familiar Environment	Less Familiar	Significant environment changes (Almost new environment)
Innovation	Little	Medium	Major
Deadline	Not Tight	Medium	Tight
Example	Payroll System	Utility Systems, DBMS	Air Traffic monitoring, ATM
