Explain the development phases of the detailed COCOMO model.

1 Answer

Answer :

Ans A software development is carried out in four successive phases, which are as
follows:
1: plan/requirements: this is the first phase of the development cycle. The
requirement is analyzed, the product plan is set up and a full product
specification is generated. This phase consumes from 6% to 8% of the effort
and 10% to 40% of the development time.
2: product design:The second phase of the COCOMO development cycle is
concerned with the determination of the product architecture and the specification
of the subsystems. This requires 16% to 18% of the normal effort and 19% to 38%
of the development time.
3: programming: This is the third phase and is divided into sub phases : detailed
phase and code/unit phase. This requires 48% to 68% of the effort and 24% to
64% of the development time.
4: integration/test : This phase of COCOMO occurs before delivery. This mainly
consists of putting the tested parts together and then testing the final product. This
requires 16% to 34% of normal effort and 18% to 34% of the development
time.
