It’s true that research is never done, but you also shouldn’t feel compelled to 'deliver' something just to meet the demands of a framework which wasn’t designed for research. Instead you need to check yourself and ask if there is enough here for there to be some reliable actions springing from it. If not, don’t deliver something for the sake of the agile theatre.
I should point out here that I’m a big fan of being agile, but focus on the benefits of that agility rather than the expectations of a framework. All frameworks are in some way wrong for you.
