PK0-005 Project Management Concepts Practice Question
A project manager is assigned to a new software development project. The requirements are well understood and unlikely to change. The project team is collocated and has experience with similar projects. Which life cycle approach is MOST appropriate for this project?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Predictive (waterfall)
Predictive (waterfall) is best when requirements are stable, the team is experienced, and the work is well understood. Agile is for evolving requirements; hybrid would be overkill; iterative is not as structured as predictive for stable requirements.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Predictive (waterfall)
Why this is correct
Predictive suits stable, well-understood requirements where change is unlikely, allowing sequential phases with upfront planning. Collocated, experienced teams reduce the communication overhead that iterative approaches address, so heavyweight change responsiveness adds little value. Fixed scope and low uncertainty let the team plan, execute and control against a defined baseline efficiently.
- ✗
Agile
Why it's wrong here
Agile embraces evolving requirements through iterative increments, so it adds overhead without benefit when scope is fixed and well understood. It is tempting because Agile suits projects with uncertain, changing requirements or frequent stakeholder feedback; here a predictive, plan-driven life cycle matches the stable, experienced, collocated team.
- ✗
Hybrid
Why it's wrong here
Hybrid mixes predictive and adaptive elements, so it introduces iterative overhead the fixed, well-understood requirements do not justify. It is tempting because hybrid suits projects combining stable and volatile components, or regulated delivery with agile development; this scenario has no uncertain element requiring an adaptive approach.
- ✗
Iterative
Why it's wrong here
Iterative development cycles are structured around repeated refinement through feedback loops, which is unnecessary here because the requirements are well understood and fixed. The correct approach, predictive (waterfall), sequences phases linearly without revisiting earlier stages. This option tempts because iterative methods excel when requirements are ambiguous or evolving, such as in exploratory projects where stakeholder feedback must reshape deliverables after each cycle.
