Pro Tips
- *Pilot tools in one practice area and one jurisdiction, then generalize once playbooks and rules stabilize.
- *Integrate with the firm DMS and matter management system early so audit trails and billing tags are always attached.
- *Map pricing to matters or consumption where possible, and reserve per user seats for daily reviewer roles to match buying habits.
- *Involve information security and outside counsel guidelines at design time, including data residency, key management, and audit exports.
- *Ship implementation accelerators like rule templates and sample workflows to shorten sales cycles with conservative buyers.
