This is the answer. I work on software that deals with millions of dollars daily; mistakes would be very costly and our team spans multiple timezones. Two things my team has going are that our lead dev understands the business case (10 years of industry experience - not just tech), when the dev team runs into an edge case our default is to email the interested parties (product owner, UX, QA) to say "I ran into this edge case that isn't covered by the stated requirements; please open a work item and prioritize accordingly". The lines of communication between DEV/UX/QA/Product needs to be very open and judgment free to deliver on an ongoing basis
