Former Infosys board member V Balakrishnan said that Vishal Sikka, the new CEO of Infosys, will have to rebuild a core team. "Sikka will have challenges ahead but the uncertainty is over. Hopefully Vishal will get growth back. NR Narayana Murthy stepping down is the right thing to do." He also said that the new CEO needs his space to operate and commit his own vision, team and strategy.
