Research methodology

The Lexology Index research process starts with qualitative analysis; we gather first-hand experience of working with nominees in the industry or practice area, and ground it with continuous quantitative analysis of a range of relevant data points to ensure a rigorous evaluation framework, consistently applied.

We canvas recommendations and feedback from corporate counsel or other clients who have worked closely with the nominees, as well as from eminent private practitioners. But we know opinions are subjective: we also build and exploit datasets to corroborate and challenge market feedback and ensure our recommendations are rooted in and supported by detailed data.

Our research team, building on 25 years of market experience, brings those data points together to create a market assessment which companies and referring law firms use daily to select the right external counsel or expert for the matter in hand.
