• It will take longer than expected.
• Not everyone will understand.
• At least one key player is not engaged.
• No matter how diligent the process, the team will miss something important.
• If everyone agrees, someone is not paying attention, or is being dishonest.
• The risk manager, lawyers, and upper level management really want to say no.
• When you are done, people will complain and you'll have to remind them of the mission.
• The result will not be what you planned.
• To the extent that you succeed, the important benefits will result from solving unforeseen complications.
