CAPM Agile Frameworks and Methodologies Practice Question
Which TWO are benefits of using an iterative approach in agile projects?
⚠ Common exam trap
The trap is assuming that iterative approaches automatically reduce documentation or cost, or that testing is postponed, when in fact iterative methods emphasize continuous testing and may not reduce cost.
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
✓
Ability to adapt to changing requirements
Option A is correct because iterative development delivers working increments each iteration, allowing the team to incorporate changing requirements between iterations rather than being locked into an upfront specification. Option C is correct because each iteration produces a demonstrable increment that stakeholders can review, generating frequent and early feedback that guides subsequent work. Option B is not a defining benefit, since agile values working software over comprehensive documentation but does not eliminate necessary documentation. Option D is not guaranteed, as iterative approaches can increase cost through rework and continuous involvement. Option E is incorrect because testing is continuous within each iteration, not postponed to the end.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Ability to adapt to changing requirements
Why this is correct
Iterative delivery produces working increments each cycle, so stakeholder feedback and newly discovered requirements can be incorporated into subsequent iterations rather than frozen at project start. This directly satisfies the stem's demand for adaptation to changing requirements, which predictive waterfall planning cannot accommodate once baselined.
- ✗
Less documentation is needed
Why it's wrong here
Iterative delivery produces working increments each sprint, but it does not reduce the documentation a project needs; governance, user stories and acceptance criteria still require recording. It tempts because agile values working software over comprehensive documentation, yet that preference concerns emphasis, not volume. Documentation scope is set by organisational and regulatory requirements, not by iteration cadence.
- ✓
Faster feedback from stakeholders
Why this is correct
Iterative cycles deliver working increments for stakeholder review at each iteration boundary, so feedback arrives during development rather than after final delivery. This directly satisfies the stem's requirement for benefits of iterative approaches, enabling early course correction and reducing the risk of building unwanted functionality.
- ✗
Reduced overall project cost
Why it's wrong here
Iterations control risk and surface defects early, but they do not lower total project cost; repeated re-planning, refactoring and incremental releases can raise it. It tempts because early defect detection avoids expensive late rework, which can offset some spend. Cost reduction is a possible outcome of specific practices, not an inherent benefit of iterating.
- ✗
Postponed testing until the end of the project
Why it's wrong here
Iterative approaches test within every iteration, so deferring testing to project end contradicts the model entirely. It tempts because sequential waterfall projects do consolidate testing into a final phase after build completion. Agile instead integrates verification continuously, giving feedback each cycle; end-of-project testing removes that feedback and reintroduces late defect discovery.
