Process makes perfect!!
As, with anything, that involves multiple people or entities having to work together, it goes much easier when everyone understands the hows and whys of working together. As a staffing professional, we must ensure we establish the process we will use to help our clients fill positions. A well established and agreed upon process makes it easier all around. Everyone knows what to expect from you and what is expected from them. Go so far as to create an SLA or SOW even. Remember a well established and agreed upon process can make working and succeeding easier. It is a win win.
