Dear Amarnath,
Greetings,
There is no doubt about the fact that your HR Skills will certainly come handy in the role of Project Management Officer(PMO).
Normally, PMO is used as an acronym to Project Management Office/Program Management Office.
Over n above that you would need to be well acquinted with Project Management Discipline as an individual. For reference purpose, visit
www.pmi.org & try n get hold of PMBoK (Project Management Body of Knowledge).
I would recommend you reading PMBoK before any other information on PMO.
Primary role as PMO would involve ensuring communication & coordination across diverse project stakeholders.
Warm Regards,
Mohit Sharma
