"We have identified a leader to take on his responsibilities," it added.
This is the 13th senior level exit from the country's second largest software services company in the past one year since N R Narayana Murthy returned from retirement as Executive Chairman to put the firm back on a high-growth trajectory at a time when peers like TCS and HCL Tech were out-performing Infosys.
