From the early years, A. S. Bhathena was a keen practitioner of ‘Management by wandering about,’ through which he kept in constant touch with his staff and workers.
A. S. Bhathena was a passionate advocate of achieving success through merit and hard work. His favourite quote was: ‘Deserve and then desire.’ He also believed in the social purpose of business, viz. that the objective of a business house is – ‘to serve the society they live in.’ He was also convinced of the need to accept diversity in people – just as you need almonds, raisins and walnuts to make a rich fruitcake, you need different types of people to make a rich organisation.
A. S. Bhathena passed away in 1991.
Born in 1935, Rohinton hailed from a Parsi family in Bombay. A graduate in economics from Cambridge, he was also an alumni of the Harvard University Graduate School of Business Administration.
Rohinton was a seer, a dreamer and above all, a great doer. His leadership transformed Thermax from a small boiler company to a multi-divisional engineering force, with a focused vision to provide solutions that conserve energy and preserve the environment. He gained recognition as a visionary entrepreneur and a management thinker.
Rohinton believed that businesses need to be built on the foundations of enduring values. ‘Profit is not only a set of figures, but of values,’ he often reminded his teams.
These values help businesses fulfil their obligations to the customer. He believed that ‘Understanding the market in depth, stretching it to the fullest potential, creating new unfulfilled needs, being obsessed in the process and emerging as a leader,’ was living a mission. According to Rohinton, ‘this is the role and the heritage of a value-added society. It is exciting, rewarding and never ending.’
Rohinton Aga passed away in 1996.
