Project Management

Been thinking about Agile dev (Scrum specifically) lately. Its great to plan "these are all of the things we will do." It helps you to stay focused on making positive moves; on progress; and on creating a habit of progress. But at those review meetings, is anyone asking "what if things went wrong? Would we be able to handle it?" Is it because it might be seen as a negative or as disruptive? An hindrance to progress? Nay-saying? Focusing on doom and gloom? This isn't disrupting the momentum, being a nay-sayer or a pain in the ass Its actually maintaining the habit of progress by helping everyone to add movements towards handling things if events do not go as planned. Like having the fire escape route for the building posted on the wall. Expect the worst, hope for the best and proceed somewhere in the middle of those two.
