ITPEC FE Morning October 2018 Question 52
ITPEC FE Morning October 2018 — Question 52 of 80
Group Decision-Making Techniques — identify team-based estimation approaches in project scheduling.
The question asks which option describes group decision-making techniques for estimating activity durations.
Answer: (c)
Group decision-making techniques are team-based approaches used to improve estimate accuracy and build team commitment:
- Brainstorming — open idea generation
- Delphi technique — anonymous expert rounds converging on consensus
- Nominal group technique — structured voting after individual input
Why not others:
- (a) — describes expert judgment (experts using historical data to provide estimates)
- (b) — describes reserve analysis (adding contingency reserves / buffers for schedule uncertainty)
- (d) — describes parametric estimating (using statistical relationships between historical data and variables to calculate cost, budget, or duration)
Key rule: "Team-based approaches" + names like Delphi, brainstorming, nominal group = group decision-making techniques.
