Dear "Agile", you are not good enough anymore
You can execute agile processes perfectly by the book and still have a product that sucks. Don’t think that being agile is going to give you answers, because not even internally you will have agreement on what it means. The goal is not to ship something into production. The goal is to build something that allows us to test our hypothesis. The best way forward may be to not ship anything at all.
