MUMBAI: India’s largest IT services provider Tata Consultancy Services Ltd (TCS) had six hours to move key operations from secure delivery centres to home locations, and this was made possible by a few who decided to live in offices to smoothen the transition, senior officials of the firm told Mint in an interview. "From a highly centralised model consisting of workspaces set in large delivery campus capable of accommodating thousands of employees, we had to switch to an extreme form of distributed delivery in a matter of days, which is not a trivial challenge," said TCS managing director and chief executive officer (MD & CEO) Rajesh Gopinathan.
