The risk manager should use the Delphi method in this situation, as this is a technique that can help

resolve differences among experts and reach a consensus on the identified risks and their

characteristics. The Delphi method is a tool used to make quick decisions with consensus. This

technique consists of sending several sets of anonymous questions to each expert. This is followed by

a group discussion after every round. The Delphi method can help the risk manager to solicit the

opinions of all experts without revealing their identities. This way, the experts can express their

views freely and honestly, without being influenced or intimidated by others. The Delphi method can

also reduce personal bias, ego, or emotional conflict among the participants. The risk manager can

use the results of the Delphi method to create a list of potential risks and their causes, effects, and

probabilities. The other options are not appropriate techniques for the risk manager to use in this

situation. Brainstorming is a technique that can help generate ideas and identify risks, but it may not

be effective in resolving differences among experts, as it involves open and spontaneous discussion.

Focus group is a technique that can help collect requirements and opinions from stakeholders, but it

may not be suitable for resolving technical disagreements among experts, as it involves a moderated

and structured discussion. Checklist analysis is a technique that can help identify risks based on

historical information and lessons learned, but it may not be helpful in resolving differences among

experts, as it involves a predefined list of potential risks. Reference: 3, 4, 5
