Customers Don’t care about your solution. They care about their problems. - Dave McClure of 500 startups
Problem Space:
Example: NASA made a zero gravity ink pen with million of dollars in investment that can write in space, while the Russians used a pencil to do the same. The problem of jumping to solution, instead of clearly describing the problem will lead to such issues and the alternate options might get missed.
Write your PRDs with a focus on “What” the product needs to accomplish from the customers before getting into “How” the product will accomplish it. “What” is the Problem Space & “How” is the Solution Space Market Disruption happens when a new product (solution space) better meets the Market needs (Problem Space)
