It’s been a homecoming for Nandan Nilekani in the most trying circumstances. The IT bellwether Infosys has hit a rough patch following the sudden exit of CEO Vishal Sikka owing to a bitter fallout with Narayana Murthy. The vacuum at the top has now been filled with Nilekani stepping in as the executive chairman, prompting him to tweet about joining the company at 26 and then re-joining it at 62. Nilekani was one of the seven co-founders and had served as the chief executive between 2002 and 2007 during which Infosys' revenue grew six-fold, from $500 million (3,200 crore) to $3 billion (19,200 crore). Having enjoyed a dream run for a good part of its 36-year existence, Infosys today is grappling in an uncertain IT landscape. Not surprising that Nilekani said his priorities were to find a CEO, reconstitute the board and shape Infosys' future strategy. Who will take charge as CEO is the big question and by the looks of it, it could well be an insider. Perhaps the “outsider” experience has been a hard one to swallow.
