Overview

This effort includes upgrading to the latest version of CGI’s Advantage platform, migrating the system to a secure cloud environment, enhancing financial reporting capabilities, integrating with external interfaces, and expanding core financial functions within the system.

As we developed deep subject matter expertise in the County’s systems and processes, Trilogy continues to support the next phase of the County’s modernization efforts, including the development of training materials to support change management and user adoption and performing analytical work to facilitate implementation and integration activities, leveraging best practices to drive efficiency and scalability.
Results

Trilogy is proud to have played a key role in this success and looks forward to continuing our partnership as we support the County in its ongoing financial management modernization efforts.
