Core competency: Effective communication
Secondary competencies: Decision making, team building
This is a question about your methods of leading discussions. Notice that the goal is to create a specific kind of discussion – creative brainstorming.
The optional responses could be appropriate in creating different types of discussions, but here you are aiming for this specific kind.
Starting the discussion with your opinion (response A) may start the conversation but it could also influence the opinion of your team supervisors.
You are in a different position than they are, and they might be influenced by your opinion, consciously or not.
When trying to establish a creative discussion, you should aim for an open conversation in which creativity can thrive.
When you keep your team supervisors' responses short (response B), you don’t allow them to be creative and the ideas you will receive will be less innovative.
This response shows ineffective communication.
Response C combines the effectiveness of responses B and D: you allow an open discussion that allows creative thoughts to flow, and you make sure that eventually, you get input from all members.
This is important, as open conversations, creative as they may be, tend sometimes to be led by dominant individuals, while more quiet individuals may not speak up.
However, their input could be valuable (decision making, effective communication).
Moreover, by making sure that you’ve heard everyone you send out a message that their opinion matters. This act also enhances team building.
In response D you allow an open discussion to take place, thus allowing creativity and teamwork (team building).
As mentioned above, the only flaw in this strategy is that some voices may remain unheard.
