Facilitating a meeting - looking for cooperation!

We are back in the conference room at Company XYZ with the whole project team for the day, again working on the WBS process. Unfortunately, a few hidden agendas are already rising to the surface.

A facility manager seems to be far too optimistic, assuming he can take on the role of GC (General Contractor) and wear a number of other hats without any problem. I am not sure why he is assuming he can take on all this work and not drop the ball anywhere, as past Lessons Learned have proven often happens when such an attempt is made. I've learned from another manager here he can be a real "stick in the mud", sometimes far too cocky about his knowledge and abilities. In a recent project where some team members tried to reorganize floor layout, the facility manager got so belligerent about it that he refused to help at all; machines that were marked for move had to be physically moved by the production manager, since help from facilities was not made available. He is unwilling to implement changes and prefers to stay in the past mode of work; he seems to think that he "knows everything", and we all know how impossible it is to work with team members who know everything and listen to no one.

The production manager who attempted to implement the changes in the past is a forward thinking man with an agenda of lean, modern processes, and smooth flow. He is working hard for the betterment of the company, and hopefully, in the end, he will take the hill and win the battle.
