From ZDNet on Satyam's top level executive movements:
S.V. Krishnan will lead Human Resources; Pavan Kumar is Chief Technology Officer; Vijay Prasad is Chief Information Officer & Head of Soft Infra group and Hari T (former HR head) will lead Global Marketing and Communications.
Now that's a change. There's been a trend in the middle management levels of large IT and BPO firms for people from operations, sales and marketing moving into HR (specially Recruitment), but it is one of the rare occasions when a head of HR is taking over a function like Marketing.
So from the big four Indian IT services firms (TCS, Wipro, Infosys and Satyam) the only HR head who's still doing the same role he was during the Y2K madness would be Wipro's Pratik Kumar :-)
