Dear Amarnath,
Greetings.
There is no doubt about the fact that your HR skills will certainly come in handy in the role of Project Management Officer (PMO). Normally, PMO is used as an acronym for Project Management Office/Program Management Office.
Furthermore, you would need to be well-acquainted with Project Management Discipline as an individual. For reference purposes, please visit
www.pmi.org and try to get hold of PMBoK (Project Management Body of Knowledge). I would recommend reading PMBoK before seeking any other information on PMO.
The primary role as a PMO would involve ensuring communication and coordination across diverse project stakeholders.
Warm Regards,
Mohit Sharma
