"I would pick a previous project that failed because of vague objectives. At the onset, leadership told us that this was going to be an exploration project. We had a lot of ideation meetings and came out with half-baked decisions. I would assign team members tasks, but once I put deliverables up for review, leadership kept asking for more revisions. We finally realized that leadership didn't really know what they wanted for the outcome and so it got shoved after a few months. In retrospect, I should have put my foot down at the beginning and asked for key performance indicators. Because of that experience, I never move ahead with a project until goals are defined and everyone understands exactly how we are going to achieve those goals."
