Greetings,
I agree there are organizations that are geographically located with many centres across the continient . Most of these centres might not be big enough to afford a support service personnel . Hence, there would be a corporate HR based out of the Head Quarter , who would run the processes along with the local centre head , who would belong to any function.
Business leaders hold shared responsiblity in HR Initiatives such as Corporate Social responsibilty , leadership development and etc. but then as the word goes its a shared responsiblity to ensure business support to make these initiatives a success . Its not over ridding each other's responsiblity or micro managing . Its all about building a synergy and letting the specialist run the core functions.
Regards,
