To be clear, I'm NOT advocating for premature abstraction, as a PM I live and die by "rule of three" when making decisions re: "let's just quickly solve this one bespoke need", vs "let's think about this more systematically".

But customers will never tell you all their requirements up front, and it's a PM's job when hearing a need from a customer to take the time to figure out if it's a single unique stand-alone problem, or simply one instance of an entire category, the other 3687 of which your customers are going to come asking for the moment they realise it's a category of problem your product is able to help with at all.
