You can accelerate your understanding by interviewing just four different experts. Try to interview them as a group to develop a shared understanding. If that’s not possible, then make sure the interviewer presents the findings to the group.

Interview the project sponsor. Understand:

• What will make this project a success?
• What’s our unique advantage or opportunity?
• What’s the biggest risk?

Understand the customer:

• What are they doing currently to solve this problem?
• Where are the key pain points?

Understand the subject matter expert:

• What are the constraints of legislation or policy?
• What are the opportunities and challenges of existing technology solutions, service design and regulatory arrangements?

Understand previous efforts:

• What have we already tried?
• To what extent has it worked and what can we understand from previous attempts?
• Why does the problem remain?

There are key rules to sharing the outputs:

• Iterate your existing work, making sure the interviews add colour and detail to your other work - eg amend the map
• Make the findings visible - eg key statistics on the wall, key quotes
• Share it across the team - present your findings
