PK0-005 Project Management Concepts Practice Question
A company is implementing a new HR system. The project manager wants to ensure that all requirements are gathered up front and the scope is fixed. Which project management methodology is MOST appropriate?
⚠ Common exam trap
PK0-005 often tests the misconception that Agile is always the 'modern' or 'best' choice — candidates must match methodology to the stated constraints (fixed scope, up-front requirements) rather than defaulting to Agile.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Predictive (waterfall)
A predictive (waterfall) methodology is appropriate when requirements are well understood up front, scope is fixed, and changes are expected to be minimal — exactly the scenario described. Waterfall's sequential phases (requirements, design, build, test, deploy) and formal change control align with the project manager's goal of gathering all requirements up front and locking scope. This is the classic choice for stable, compliance-heavy, or contract-driven projects like HR system implementations with fixed deliverables.
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 methodology fixes scope, schedule and cost baselines early, with requirements fully elicited before build begins. That matches the stated constraint of gathering all requirements up front and locking scope, whereas adaptive approaches deliberately welcome late change.
- ✗
Hybrid
Why it's wrong here
Hybrid blends predictive and adaptive delivery, so parts of the work remain iterative and scope is not fully fixed up front. It is tempting because it suits mixed portfolios, but the stem requires all requirements gathered and scope frozen before build, which pure waterfall delivers.
- ✗
Kanban
Why it's wrong here
Kanban manages continuous flow with no fixed scope or up-front requirements phase, so it cannot satisfy the stem's demand for gathered requirements and locked scope. It is tempting because it visualises work well for operational or support teams, but predictive waterfall is correct when scope is fixed before delivery.
- ✗
Agile
Why it's wrong here
Agile welcomes changing requirements throughout delivery, directly contradicting the stem's fixed-scope, up-front-gathering requirement. It is tempting because it handles uncertainty well on evolving products, but waterfall is correct when scope is defined and baselined before execution begins.
