Final answer:
The mode of intermediate COCOMO for a medium-sized project is Semi-detached. The COCOMO model classifies projects into three modes: Organic, Semi-detached, and Embedded, with Semi-detached being the correct mode for medium complexity projects.
Step-by-step explanation:
The mode of intermediate COCOMO for a medium-sized project is Semi-detached. The COCOMO (Constructive Cost Model) is an algorithmic software cost estimation model developed by Barry Boehm. The model is used to estimate the cost to develop software projects.
It has three modes of estimation which correspond to the size and complexity of the project: Organic for small, simple projects, Semi-detached for medium-sized projects with mixed complexity, and Embedded for projects with complex hardware and software constraints or rigorous regulations. Therefore, for a medium-sized project, the Semi-detached mode would be the appropriate choice.
