This Leading Practices Profile updates the 2005 ACC Leading Practices Profile, Law Department Metrics. In 2013, ACC revisits the question of law department metrics as a tool for measuring success and improving value delivery. Through interviews with 10 law department leaders in this area, we present here the updated design, development and implementation approaches of highly effective and diverse metrics models. Department leaders profiled here offer vital advice on how to capture and use metrics results to drive enhanced law department and outside counsel performance. These thought leaders also share resources and tools that have facilitated their development and evaluation of strong metrics practices, in the hopes that these can help other corporate counsel seeking better ways to measure, and ultimately to maximize, their own legal department’s performance.
