Question

What are the estimation models used in COCOMO II?

1) Basic COCOMO
2) Intermediate COCOMO
3) Detailed COCOMO
4) All of the above

Answer 1

The correct answer is Option 4. The estimation models used in COCOMO II are Basic COCOMO, Intermediate COCOMO, and Detailed COCOMO.

Step-by-step explanation:

The estimation models used in COCOMO II are:

1. Basic COCOMO: This model provides a rough estimate based on the size of the software project. It takes into account the number of lines of code and uses a set of cost drivers to calculate effort and duration.
2. Intermediate COCOMO: This model expands on the basic model by considering additional factors such as software reliability, complexity, and development environment.
3. Detailed COCOMO: This model provides a more detailed estimation by considering specific characteristics of the software project, such as personnel resources, software reuse, and maintenance.

COCOMO II features three models:

1.Application Composition Model

2.Early Design Model

3.Post-Architecture Model

Each of these three models serves a different purpose within the COCOMO II framework and is applied at various stages of the software development life cycle. Therefore, the correct answer is none of the original COCOMO models are used in COCOMO II.
