Rishad Premji, eldest son and a Harvard Business School graduate, was already Wipro's chief strategy officer. He joins the board from May 1.
The appointment was announced on Tuesday alongside Wipro's fourth-quarter earnings and a modest 2 per cent rise in profit. That beat expectations of a slight dip, thanks to a rise in its Western clients' technology spending.
Wipro founder Azim Premji took over his own father's ailing vegetable oil business in the mid-1960s. He diversified into making hydraulic cylinders in the 1970s and struck out into information technology in 1980.
"There is nothing much to be read into this other than the fact he is really representing shareholders' interest," Wipro's chief executive officer T K Kurien told reporters, when asked about Rishad's elevation to the board.
Wipro has been looking to boost revenue from high margin services that help overseas clients seeking to speed up automation and do more business online.
Rajan Kohli, head of Wipro's newly-formed digital business unit, said last month the unit aimed to generate $1 billion in annual revenue within three years, which would make it one of the company's top sources of income.
