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.

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
