Last year Vetasi's Mark Robbins presented an update on the RFE process and active RFEs at the #TUCMaximo User Group meeting.
The slides for this presentation are available to download and explain the RFE process, as well as giving an overview of the most active RFEs at the time of the User Group meeting. They also include tips about the best way to ensure that an RFE is easy for IBM to agree to.
These slides are available here:
