NEW DELHI — India Inc. suffered a new blow on Friday when the chief executive of one of the country’s leading technology outsourcing companies suddenly resigned, a surprise move he attributed to “a continuous drumbeat of distractions and negativity.”

The departure of the executive, Vishal Sikka, from Infosys comes just months after a struggle at the top of the Tata Group, a powerful Indian conglomerate, focused attention on a variety of problems in the country’s corporate governance and culture.

Both companies symbolized a shift in India’s business mind-set in recent decades, as they looked overseas to court clients and deals. Their success in recent years — Infosys counts a wide range of global companies as its clients, like the automaker Honda, the beverage seller Diageo — has come as India’s overall economy has seen faster growth.

Their more recent struggles, however, have also held similarities, with both companies being caught in battles between the goals of their original founders and a new generation of executives.
