Consultants normally charge a high $ per hour rate.  When you work them, the best way to make the best use of their time and to keep your cost down is to BE PREPARED.  Send as many documents and information for a meeting prior to the meeting.  Don’t wait to share it at the meeting.  All members participating in the meeting should have equal knowledge and materials.  Staff member that play games to have surprise information to show how valuable they are or how intelligent they are is a waste of time and actually works against the goal of the project and the team.  Many times when I experience this, I feel like I am the only one making decisions in the best interest of the company.  Many people have hidden agendas, like getting ahead on the career ladder, impressing the boss, putting other staff down.  It’s a jungle out there.  Check your ego at the door.  This is not the time to waste anyone’s time. Send Agendas and information prior to the meeting to make the best use of your time with your Consultant.
