Hi, @CAM
Thank you for posting in Microsoft Q&A forum.
What is your confusion? Are you confused on SCCM(system center configuration manager) and MECM(Microsoft endpoint configuration manager)?
SCCM and MECM are the same thing, it was a part of system center suit, so we called it SCCM. And now it's a part of Microsoft Endpoint Manager, so we call it MECM now.
And we usually call SCCM as MECM, MEMCM, ConfigMgr, configuration manager, CM... they are all the same thing.
