This is what I came up with (what do you think?):
-How do you balance short term improvements with long term innovation and new revenue opportunities?
-How do you make product decisions using different market, portfolio, and client analysis techniques?
-What are the components (including success metrics) you include in a business case or MRD for different situations?
-Which among the many different PRD or requirement documentation options do you use?
-How do you change the organization of a team and its processes based on the stage and size of the product line and the company? (i.e. How agile should you be?)
