Autonomy has continued to integrate their products into the Worksite document management system they acquired with Interwoven last year. The lack of integrated workflow has always been a weakness in the otherwise strong Worksite product, with clients having to create their workflows in tools such as Flosuite and Metastorm and integrate these into their DMS.

The Autonomy tool apparently includes "modeling and simulating business processes via visual tools, rules-based routing, real-time activity monitoring, secure connectivity into other business systems, electronic forms and digital signatures", giving it pretty much all of the functionality law firms require for workflows.
