Annual Legal AI OS Index

DEFINITION

The Annual Legal AI OS Index is Advanta's planned annual publication of the aggregate maturity distribution of legal functions across the five bands of the Maturity Stack. Sourced from opt-in diagnostic submissions, the Index reports the cluster of investments functions at each band have made and the observed correlation between Defensibility-quadrant investments and avoided-incident rates. First publication targeted for 2027; by the second annual publication (2028), the dataset will support comparative claims about ROAI performance and incident exposure across cohorts.
