In his rare public comments involving a rival, Wipro Chairman Azim Premji on Friday said his company's organisation structure was "superior" to that of Infosys Technologies.

"I think, our structure is superior to the Infosys global delivery model," Premji told reporters here in response to a question on how Wipro's organisation structure compared with that of Infosys' global delivery model.

"Frankly, I have not fully understood the Infosys global delivery model. Also, you must appreciate that Infosys is still struggling in trying to establish a verticalised structure."

He, however, said that both structures had their own merits.

NASDAQ-listed Infosys and New York Stock Exchange-listed Wipro, the country's second and third software exporters, respectively, are Bangalore's IT showpieces and are often subjects of comparison.

"We are quite clear (about) what we wanted to do and are confident that we can do," he further said at a press conference to announce quarterly results.
