ITPEC IP October 2024 Question 55
Which of the following is a method to break down the required activities into a hierarchical structure in software development?
Explanation
WBS — the Work Breakdown Structure decomposes the project's work into a hierarchy.
Starting from the whole project or its main deliverables, the work is divided level by level into smaller elements, down to work packages that can be estimated, assigned and tracked. Building a WBS also exposes work that would otherwise be missed.
Answer (d)
Why not others:
- •(a) CMM — the Capability Maturity Model, which rates how mature an organization's software development process is
- •(b) ITIL — a collection of best practices for IT service management
- •(c) PERT — an arrow diagram of activities and their dependencies, used to schedule the project and find the critical path; it orders activities rather than breaking them down
Key rule: A WBS defines what work there is; PERT and Gantt charts then decide when it is done.
