Once a year, the attorneys and staff from Southern California Edison Co. fill out report cards for the firms to which the company farms out legal work. The reports grade the firms according to how well they met Edison's expectations — and budget.

"At the end of the year, we have a committee in our department that does an assessment of the work performed by the firm," senior vice president and general counsel Russell Swartz said. "They interview the attorneys who have interacted with the firm. We also talk to some of the business representatives and nonlawyers who have had interactions with the law firm."
