It would be good to see your approach, from which we can comment/add. If you're really looking to develop your hypothesis-driven approach, nothing beats a one-on-one with a coach!
My view is that your framework is actually your hypothesis. It's a bit nuanced, but bear with me :)
Your framework is your structure for approaching the problem. It consits of a few main areas you'd like to look at. Inherent in your framework is a view that "If I answer A, B, and C, then we have an answer"
So, for market entry:
1) If the market is big, and it's growing, then we still want to considering entering
2) If #1 = yes, then let's see if it's attractive...can we win there? Is our product good/better than our competition's? Etc. If yes, let's definitely consider entering.
3) If #1 and #2 = yes, then, when we do enter, are we sure we can win? I.e. do we have the right plans. Will implementation actually pan out? Do we have the expertise, capital, etc.? In other words, if #2 is the thearectical, #3 is the reality.
Then, your summary becomes "I believe we should enter the market, if we can prove it's a good market, the it's attractive to us specifically, and that we will win it".
^Now this is a hypothesis...try it out with the prompt you've posted! :)
