Good advice - I'm sure we've all been in at least one situation like this!

Problem is, you've dodged one bullet in the meeting ... great ... but there is still going to be at least one very unhappy stakeholder connected with the project who is going to continue throwing monkey wrenches all the way through until the root cause is addressed?

In my experience, 99% of the time, situations like this arise because communication was handled poorly upfront, or affected stakeholders didn't feel properly engaged or consulted. 1% of the time, people are just jerks ... and handling these people are partly what executive sponsors are for.
