Lenny Rachitsky starts off his article on A three-step framework for solving problems with a really good insight:

Though many factors contribute to a project’s failure, nothing is more certain to cause a project to fail than a misunderstanding of the problem you are solving.

He spends the rest of the article focusing on how to develop and rally around a good problem statement, which is an essential skill to have for any product manager. I really like this framework and am keen to try it on my next project, alongside a version of Marty Cagan’s Product Opportunity Assessment that we’ve adapted for our specific needs.
