If Premjis total belief in a professionally-run group predates similar moves by liberalised India Inc by almost three decades, his lasting stamp on Wipro will surely be his insistence on integrity. In 1987, he refused to pay a bribe of Rs 1 lakh to ensure power supply to a manufacturing facility at Tumkur in Karnataka. Instead, Wipro generated it's own power, a move that cost them close to Rs 1.5 crore. Says Subroto Bagchi, vice-president, Lucent Technologies, who once led the Quality Mission in Wipro: Premji has gone on record to say that in Wipro, integrity is non-negotiable, to that add quality. He leads that movement in a deep, personal way. No member of the Premji family is employed in Wipro, and sons Tariq and Rishad have to earn their place in the corporation. The fact that Wipro does not bid for contracts where bribes could influence the final decision has helped bolster its position in sensitive deals, like defence and space contracts. Says Ranjekar, Integrity is a sound proposition in the long run. It builds customer and employee confidence.
