You meet with your project team to review the work breakdown and to develop an activity list. They agree with the scope but seem unwilling to commit as you start making assignments. They keep talking about things that could go wrong, instead of focusing on how to get the work done. You are not getting their buy-in, so what do you do next? You go through the plan with them one more time and confirm that they agree with the scope and activity list. You define an escalation process for them to alert you immediately if issues arise. You schedule a meeting to let them brainstorm things that could go wrong. They are already tired of project planning, so you doubt they will identify anything new, but hopefully this will help them get comfortable with the current plan
