In-house legal teams are facing growing expectations — not just to manage risk and ensure compliance, but to do more with less while operating as strategic business partners. The ROI question is no longer just “does AI save time?” — it’s whether legal can scale support without proportional headcount growth while keeping external spend disciplined as the business moves faster.

Generative AI is a promising unlock. Early wins can spark interest, but scaling adoption — and unlocking full value — often depends on aligning legal, procurement, and executive teams around a clear, defensible business case. This guide is designed to help legal leaders build that case, with ROI framing that supports both operational efficiency and long term strategic enablement.

At Harvey, we define ROI as the business value created when legal teams are able to deliver higher-quality work, faster — whether that means avoiding incremental headcount, improving the department’s spend profile, accelerating turnaround times, or deepening legal’s role as a strategic partner to the business.
