My advice: A structured instruction
A more effective approach is to provide a clear and structured instruction when a group starts an exercise. I personally use the following structure:
Start by creating a connection to the topic so people know something new is beginning and can focus their attention.
For example: We are now going to put the theory about Product Owner maturity into practice. What are the differences between theory and practice? And how can we help each other deal with this in a practical way? After this exercise, you will have a clearer picture of your development opportunities and will have exchanged practical tips on how to act from a mature position.
The invitation is the most essential part of the instruction. This sentence provides direction and should not be too narrow, as that can limit inspiration, nor too broad, as that can cause the group to remain vague and drift.
For example: I invite you to map your own practice onto the five levels we discussed. Where do you see yourself in this model, and how can you apply more maturity in your role?
Next, indicate how much time participants have and how they will work, for example in pairs or small groups, without giving a command. If you do, people may start immediately while your invitation is not yet complete.
For example: You will interview each other in pairs on this topic. You have 15 minutes in total, so each person will have five minutes of the other’s full attention.
Now take time to answer questions related to steps one through three.
For example: Are there any questions about the assignment?
After answering the questions, repeat the invitation, the time, and the group setup. Do this even if there are no questions, so everyone is clear on what to do.
For example: You will now map the five levels of the model onto your own practice. The goal is to gather tips on how to apply more maturity in your role. You will work in pairs and have a total of ten minutes.
Finally, let participants know they can begin.
For example: Go for it.
