By Nivedita Bhattacharjee and Sumeet Chatterjee MUMBAI (Reuters) – Infosys Ltd, Indias second-largest IT services exporter, has for the first time picked an outsider as chief executive officer, as it seeks to boost sales of high-margin services like cloud computing and stem a staff exodus. Vishal Sikka, a former member of executive board at German software company SAP AG, has the technical savvy to herald what analysts expect will be a strategy overhaul at Infosys, which, like its competitors Tata Consultancy Services Ltd and Wipro Ltd, has relied on labour-intensive, low-margin contracts from Western clients. Some investors say Infosys failed to move up the value-chain because of its risk-averse management culture. Infosys needs some change and with his track-record in emerging technology areas, high value services, Sikka will be able to bring that change, said Juergen Maiar, a Vienna-based fund manager for Raiffeisen Euroasien Aktien, which owns $300 million worth of Indian shares including Infosys.
