How did Wipro use employee empowerment and rewards to encourage continuous improvement?

"Wipro also adopted Toyota’s kaizen system of soliciting employee suggestions. Priya, who has worked for Wipro for years, submitted several kaizen and was delighted when her bosses responded promptly to her suggestions. “Even though it’s something small, it feels good. You’re being considered,” she says. Empowerment in the workplace washed over into her private life. As the first woman in her family to attend college, she told her parents they may arrange her marriage only to a man who will not interfere with her career. Kurien and his managers work hard at boosting employee morale, offering rewards—pens, caps, or shirts—to employees who submit suggestions to kaizen boxes. And each week, a top-performing employee receives a cake. Murthy, an accountant who hopes to be Wipro’s chief financial officer someday, spearheaded an effort to cut government import approval times from 30 to 15 days. He got a cake with his name written on it in honey. “I was surprised management knew what I was doing,” he says. “Now I want to do more projects.”"
