MIT and Harvard are co-founders of edX: https://www.edx.org/. While not fully online, MIT does allow students who earn a MicroMasters in Supply Chain Management online to apply that course work to the on campus masters program: https://www.edx.org/micromasters/mitx-supply-chain-managemen....

None of those are accredited programs and employers don't care at all if you have them completed. They are treated on the level of MS certified beginner in something.

edX has partnered with employers who have endorsed many of the programs. As for the MIT SCM program, the full masters is accredited.
