Each pair should have a clearly stated strategy for the questions that they are going to ask when they meet with their respective interviewees.
From our schema of different stakeholders and their contribution to the issue of child safety and guns – what is it that we need to know, what can we learn from them, what is the best way to structure the interview/conversation, how will you record the interview/conversation – write notes, collect images or diagrams, record it.
Remember we are doing these because we want to understand the issue from different perspectives as is relevant to the breadth of stakeholders involved in this problem.
