IT Systems Working Group

A monthly, virtual forum that gives market participants early, practical insight into upcoming REM IT changes so they can plan and prepare. Each session will focus on a specific topic or topics, including planned interface and API updates, expected technical impacts, and include time for questions and discussion. The regular cadence supports ongoing readiness as capabilities are released in phases.

This forum will help participants understand which systems and interfaces will be affected when, what connectivity or access changes may be required, and how to plan, sequence, and resource their internal work ahead of each sandbox release.

Sessions will be open, transparent, and aligned with general delivery timelines. A summary of each will be shared afterwards, however they will not be recorded and posted.

Audience: The group is intended for those responsible for implementing and integrating REM-related IT system changes, with consistent core participation and additional subject matter experts joining as needed.
