Assignment B

Consider a project to develop a full screen editor. The major components identified are (1) screen editor (2) command language interpreter (3) file input output, (4) cursor movement and (5) screen movement. The sizes for these are estimated to be 4K, 2K, 1K, 2K and 3K delivered source code lines. Use COCOMO model to determine: (i) Overall cost and schedule estimates (assume values for different cost drivers, with at least three being different from 1.0) (ii) Cost and schedule estimates for different phases.

Q2 - Explain why a design with low coupling helps maintainability

3. Discuss the significance and use of requirement engineering. What are the problems in the formulation of requirements?
