Book excerpt: An article in the Harvard Business Review once said that the most valuable skill for the 21st century manager is the ability to work across cultures. Around the world, it is increasingly recognized that an understanding of a country's work culture plays a significant part in success at one's job. Every group of people has subtle drivers of behaviour, values and beliefs, an understanding of which could help you navigate your way around the workplace. Indians are no exception. We have some innate strengths that we seldom take credit for. Like the uncommon capacity to deal with ambiguity and to think on the fly; the emphasis we place on forming and sustaining relationships at work; and the willingness to go beyond the call of duty as we see our jobs as an extension of our personal lives. And then there are traits that may confuse the uninitiated at first and need some getting used to - such as saying 'yes' to an assigned task when we actually mean 'no', our flexible attitude to time, and the famous Indian head wag. Based on extensive interviews with corporate leaders - Indians as well as expatriates and repatriates, who offer insider and outsider perspectives on the psyche of the Indian in the workplace - How India Works is a guide to the cultural nuances and complexities of working in India. It will make your life in office a little easier.
