Both yes and no. A notebook or a piece of paper should be carried with you. You may maintain track of the conversation by writing down only the keywords or by using a mapping approach. We do not recommend that you take complete notes. You’re not there to take minutes; you’re there to talk. The keywords/key phrases can be used to summarise and bring attention back to the issue.
This also aids in the identification of your strategy and ideas on the topic. However, it is fair to say that the ideal strategy is to listen and take mental notes rather than wasting time writing down remarks from other team members. If you’re not sure, make a list of keywords. Practice remembering discussions and relevant terms in your head and being able to recall them when needed. Although summarising a group discussion session is typically optional, it is a good idea to be prepared if you are required to do so.
