BTI’s Methodology and Approach

BTI’s goal each year is to be objective and transparent in our rankings. The A-Team is a data-driven ranking based solely on in-depth telephone interviews with leading legal decision makers. This research is independent (no law firm or organization other than BTI sponsors this study) and unbiased. 

Each year, BTI reaches out to a strategically designed group of top legal decision makers at large organizations with $1 billion or more in revenue. We target the decision makers in the industries who spend the most on legal affairs as well as thought leaders and innovative Chief Legal Officers. Our survey also includes Chief Legal Operating Officers and business executives who hire and influence the selection and hiring of law firms. 

Participants are granted confidentiality at the individual and organizational level.


BTI’s scoring system relies on 3 variables to leave no room for subjective opinion or judgment:

  • Importance of each of the 17 activities to legal decision makers when assessing legal providers

BTI asked legal decision makers: On a scale of 1 to 10, with 10 being the most important,
how important are each of the following activities when you hire or evaluate a law firm?

  • How difficult it is for a legal decision maker to find a law firm performing well in each of the 17 activities
    (in essence, does the activity differentiate one law firm from another)

BTI asked legal decision makers: On a scale of 1 to 10, with 10 being the most difficult, how difficult
is it for you to find a law firm performing at best-in-class levels in each of the following activities?

  • Candid, open-ended feedback from decision makers as to which law firm stands out as the best in
    each of the 17 activities

BTI asked legal decision makers: For each of the following activities, can you please tell me
which firm you consider best?

The 17 Activities—A Brief History

28 years ago, BTI began the first and longest-running continuous survey with C-level buyers of professional services. The goal was to understand what drives the absolute best relationships with professional services firms—how and why top executives pick the service providers they do.

More than 14,000 in-depth telephone interviews later, BTI has isolated 17 activities proven to be essential to delivering superior client service and driving the best relationships.
