You just got off phone with Bud, following similar call with Betty. They are both concerned that position will be filled with someone outside Chicago office. They actually wish for having their teams more involved in project and feel this is excellent opportunity for one of their people to step up. Though, having someone from Little Rock or Boulder office on project actually decreases representation from Chicago. (You made very strong effort at staffing team equally, and this would change that, giving one location more people than other locations.) You are leaning toward having Cathy on project team because of her past experience and that would not unfavourably impact project much.
