Exam CBAP topic 1 question 185 discussion

Answer is incorrect. It is "Estimation" technique. BABOK V3 10.19.3

The Delphi Technique is a type of survey-based requirements elicitation technique that involves gathering input from a panel of experts through multiple rounds of anonymous questionnaires. The responses are aggregated and shared with the group after each round to refine opinions and reach a consensus. This method is particularly useful for forecasting, decision-making, and identifying requirements in complex projects.

Delphi: uses a combination of expert judgment and history. There are several variations on this process, but they all include individual estimates, sharing the estimates with experts, and having several rounds of estimation until consensus is reached. An average of the three estimates is used. BABOK V3 Chapter 10 page 272

The Delphi method is a forecasting process framework based on the results of several rounds of questionnaires sent to a panel of experts.

BABOK V3 confirms that the Delphi Technique indeed involves gathering individual estimates from experts, sharing these estimates, and iterating until a consensus is reached. This aligns with the characteristics of a survey-based approach, where opinions or estimates are collected from multiple participants and aggregated to reach a collective decision or consensus. Therefore, the Delphi Technique is classified as a survey-based requirements elicitation technique.

Answer a) is correct. Delphi technique is surveying a panel of experts..

none of the options are correct as it is a type of Estimation Technique

Round table means all the experts are together discussing and coming to conclusion. where as in the Delphi technique, experts are sent surveys periodically with feedback of responses from other experts till a consensus is agreed. hence survey is the nearest one

again looks more like round table...beacuse it involves panel of experts (Round table)

Delphi is Survey... simple and short.

Given these answers, A is the closest one

The answer should be A. The Delphi method is a process used to arrive at a group opinion or decision by surveying a panel of experts. Experts respond to several rounds of questionnaires, and the responses are aggregated and shared with the group after each round.
