Different project Modes/Types used in the Basic COCOMO 81
Basic COCOMO model: It estimates the software roughly and quickly. It is mostly useful for small medium-sized software. There are three modes of development.
- Organic
- Semi Detached
- Embedded
We used these three different modes of development to calculate the project effort, development time, average staff size, and 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 |
