Check out this post by Tom Collins at morepartnerincome.  Tom refers to an article by Bob Burns at Brouse McDowell in Akron, Ohio.  Bob is a former inhouse attorney and has both selected and been selected, so he knows of what he speaks.  The article says  “I believe that a business should consider the ‘Five C’s’: (1) competency; (2) capacity; (3) commitment; (4) communication; and (5) cost.”
