Nearly one third of top US corporates do not measure law firm performance in any manner, according to a group of legal operators. According to the Corporate Legal Operations Consortium’s 2017 State of the Industry Survey, of those which do measure law firm performance, 21 per cent opt for an outcome based evaluation whilst 18 per cent looked for informal qualatative feedback. Meanwhile half do not rely on formal law firm ratings and use other measures to assess performance. The findings also found that medium sized corporations spend more of their legal budget on outside counsel than large or small comanies.
