PK0-005 Project Management Concepts Practice Question
A project to build a website is expected to take 6 months with a fixed budget. During planning, the team determines that the requirements are well-understood and unlikely to change. Which methodology is most appropriate?
⚠ Common exam trap
PK0-005 often tests the methodology selection criteria, catching candidates who default to Agile as 'modern' without considering that stable requirements and fixed budgets favor predictive.
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
A predictive (waterfall) methodology is most appropriate when requirements are well-understood, stable, and unlikely to change, and when the project has a fixed budget and timeline. Predictive approaches emphasize upfront planning, sequential phases, and formal change control, which aligns with the 6-month fixed-budget website project with clear requirements. Agile, Scrum, and Kanban are better suited for evolving or uncertain 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.
- ✗
Kanban
Why it's wrong here
Kanban manages continuous flow of work items with work-in-progress limits, lacking the schedule and budget forecasting a fixed six-month, fixed-budget delivery needs. It suits ongoing operational or support work, not a defined-scope project with a firm deadline. A predictive methodology fits here.
- ✓
Predictive
Why this is correct
Stable, well-understood requirements and a fixed budget suit a predictive (waterfall) approach, where scope is defined upfront and delivered through sequential phases. Its emphasis on early detailed planning and change control directly satisfies the stem's constraint that requirements are unlikely to change.
- ✗
Agile
Why it's wrong here
Agile suits evolving requirements delivered in short iterations, not a fixed six-month scope with a fixed budget. Its iterative replanning adds ceremony without value when the requirements are already well-understood and stable. A predictive, plan-driven methodology matches this scenario.
- ✗
Scrum
Why it's wrong here
Scrum delivers value through short sprints with an evolving backlog, assuming requirements will change. With well-understood, stable requirements and a fixed budget and timeline, sprint replanning adds overhead without benefit. A predictive, plan-driven approach is the appropriate methodology for this project.
