One of the main goals from business to the developers is delivering features faster. Sometimes for the sake of maximizing the speed business is ready to sacrifice quality. What is the best course of action in this case for an expert, whose job is to ensure quality? In my talk I want to tell you about the Feature Flags technology, which allows managing such conflict of interests, and about my experience of work with this technology. The talk might be interesting for those who are stuck in the "velocity vs quality" dilemma and for those who are interested in process organization in QA and development in general.
