(i) Small projects with minimal documentation
(ii) Medium projects with moderate documentation and staffing
(iii) Large projects with extensive documentation
(iv) Projects with very high complexity and risk

Answer: (ii) Medium projects with moderate documentation and staffing

In the COCOMO model, projects are classified into three types:

  • Organic — small, simple projects with a small experienced team, minimal documentation (e.g., a payroll program for a small firm).
  • Semi-Detached — medium projects with moderate documentation and staffing, a mix of experienced and inexperienced developers, and moderately rigid requirements (e.g., a new DBMS or inventory system linking to an existing one).
  • Embedded — large, complex projects with very tight requirements, extensive documentation, and high complexity/risk (e.g., real-time control software running in hardware).

Why the others are wrong:

  • (i) describes organic projects.
  • (iii) and (iv) describe embedded projects.

Hence a Semi-Detached project is a medium project with moderate documentation and staffing — option (ii).
