A simple exercise that complements exploratory, discursive, and creative workshops with insights and opinions from outside. Use this exercise when brainstorming ideas, developing a new product or service or creating a strategy or plan that will include others. Participants phone a co-worker and ask them questions relevant to the task. This quickly generates meaningful input from a range of “outside” perspectives. Often, participants will be surprised at how simple it was to solicit this input and how valuable it is to the process.
