PK0-005 Practice Question: A project manager is identifying risks using the…
A project manager is identifying risks using the Delphi technique. Which TWO of the following are characteristics of the Delphi technique?
⚠ Common exam trap
PK0-005 often tests the contrast between Delphi (anonymous, multi-round) and brainstorming (open discussion, single session) — candidates pick 'open group discussion' or 'one round' by confusing the two techniques.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Participants are anonymous
The Delphi technique is a structured expert-judgment method in which participants respond to questionnaires anonymously, so option B is correct because anonymity prevents any single expert from dominating or being influenced by others' status or authority. Option C is also correct because Delphi deliberately iterates: the facilitator collects responses, summarizes them, and circulates follow-up questionnaires over multiple rounds until consensus converges. Option A is wrong because a single round would not allow the iterative refinement and consensus-building that define Delphi. Option D is wrong because identifying participants would destroy the anonymity that is central to the technique. Option E is wrong because open group discussion describes brainstorming or focus-group methods, not Delphi, which uses controlled, written, anonymous feedback rather than face-to-face debate.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
One round of feedback
Why it's wrong here
Delphi iterates through multiple rounds of anonymous questionnaires until consensus converges, so a single round of feedback contradicts the method. It is tempting because one round resembles a plain survey or expert interview, which would be the correct approach when a quick, one-off opinion is sufficient and consensus building is unnecessary.
- ✓
Participants are anonymous
Why this is correct
Anonymity lets panellists submit and revise judgements without social pressure or dominance by senior voices, which is the defining mechanism separating Delphi from interacting groups such as brainstorming or nominal group technique. This satisfies the stem's requirement for a genuine Delphi characteristic, since controlled feedback across anonymous rounds converges expert opinion.
- ✓
Multiple rounds of questionnaires
Why this is correct
The Delphi technique gathers expert judgement through successive questionnaire rounds, with responses consolidated and resubmitted until consensus emerges. This iterative structure distinguishes it from single-pass techniques such as brainstorming, satisfying the characteristic described in the stem.
- ✗
Participants are identified
Why it's wrong here
Identifying participants is a genuine Delphi step, but the question asks for characteristics of the technique itself, and expert selection alone does not distinguish Delphi from any other expert-judgement method. It is tempting because anonymity depends on choosing qualified panellists, yet that is preparation, not the defining iterative feedback characteristic.
- ✗
Open group discussion
Why it's wrong here
Delphi deliberately removes open group discussion so panellists answer anonymously and independently, preventing dominant personalities and groupthink from skewing estimates. It is tempting because open discussion is central to brainstorming and nominal group technique, where face-to-face debate is the intended mechanism for generating and refining risk ideas.
