I actually landed up in a weird situation a few days back when working on a story. The story asked us to implement a certain functionality as-is in the older website which we were migrating. The business asked us devs to find out what the functionality was in the old website, tell them, and implement the same as well in the new site !!! Adding more to it, there was no one to validate whether developer findings were correct or not.
Wonder where this will go .. scary !
