The structure of customer development interviews looks like this:
Start with exploratory interviews to get to know who you’re talking with
Dive deeper into your potential customers’ problems, pains, wants, needs, and preferences, and compare those needs with the way you plan to meet them by conducting validation interviews
Present your solution to potential customers, allow them to test it, and learn from their feedback through satisfaction-oriented interviews
Regularly conduct efficiency interviews to stay relevant by improving your target customer experience and evolving your product
