What product framework do you use in your work? (discussion)

Hey, Product people!

What product framework do you use for working on your product and why?

There are lots of frameworks like:
– User Story
– Job Story → JBTD
– Empathy Canvas
– Customer Journey Map
– Customer Development
– Lean Canvas
– Product Alignment Approach
– HEART
– 11 Star Experience
– Support Driven Development
– Working Backward
– Double Diamond Model
etc.

If you don't use any framework, why not? What does the process of working on your product look like?
