When to use this combo
You want to find a product idea by deeply understanding customer needs — not just what they say they want, but the underlying "job" they're trying to accomplish. You believe the best products come from understanding the problem better than anyone else.
Is this combo right for you?
Use this combo if you're an empathetic observer who loves talking to customers and watching how they actually work. You believe that customers can't always tell you what they need, but their behavior reveals it. If you enjoy user research, ethnographic observation, and asking "what are you really trying to accomplish?" — this approach will resonate.
Step-by-step walkthrough
Use Jobs to Be Done to identify the underlying "job" customers are hiring products to do. Focus on the functional, emotional, and social dimensions: "When [situation], I want to [motivation], so I can [expected outcome]."
Apply the Double Diamond process — first diverge (explore the problem space broadly), then converge (define the specific problem). Then diverge again (generate many solutions) and converge (build the right solution). Don't skip the problem-definition phase.
Create an Assumption Map — list every assumption your idea depends on, rate each by importance and uncertainty, and test the riskiest assumptions first. Kill bad ideas early and cheaply.
