Problem-Statement Focused Hypothesis
This is a framework to help ground experiment ideas (or solutions) in research, utilizing 'problem statements' as the bridge. This enables you to ensure your tests focus on problem statements, which are grounded in research, and allows for alternate 'solutions' to be proposed as long as they are both grounded in the same hypothesis (and problem statement)
Use Cases
Are you having trouble getting approval on experiment designs?
It could be that you are fixating on solutions without properly vetting out if it's a problem for users, or that you haven't grounded your hypotheses in proper research.
