Drafts, reviews, and maintains outside counsel guidelines (OCGs) — the operational document that sets expectations for how external law firms bill, staff, communicate, and deliver legal services. OCGs are the single lowest-cost, highest-impact intervention available to an in-house legal ops function. 60% of in-house teams don't have them. Of the 40% that do, 87% barely enforce them. This skill encodes the methodology for building OCGs calibrated to the team's maturity level and producing the internal business case to get them adopted.
