Strategy matters. Speed may beat strategy for digital start-ups, but ex-consultant Nooyi knows that incumbent companies still need a plan everyone can get behind: hers is to push more 'good for you' healthier snacks while maintaining the classic Pepsi 'Fun for you' (yes really) gutbusters too.
Purpose is profitable. People not only like to work for companies that do good and also do well, they also like to buy more stuff from them. So Nooyi's attempts to make Pepsi get healthy work for employees, consumers and the bottom line simultaneously: Q1 sales were up 1.6%, not much but a whole lot better than the 11% fall at arch-rival Coke.
Don't bulldoze critics, co-opt them. Fast food is the next tobacco as obesity and diabetes head for epidemic levels in the West. Nooyi's response is not to attack the enemy but to engage with them - she has even hired an endocrinologist, Dr Mehmood Khan, as chief scientific officer to help reduce the sugar and fat content of Pepsi's products.
Communicate, communicate, communicate. 'You cannot over-invest in communication skills,' says Nooyi, who has over 29,000 followers on Twitter. When the Kendall Jenner ad went pear-shaped, she pulled it, apologised and moved on.
Be a rebel - but not too much. Born and raised in Madras, as a kid Nooyi defied the stereotype of reticent Indian girlhood, playing women's cricket and being in a rock band. But she won places at both the prestigious Indian Institute of Management in Calcutta, and Yale School of Management in the US.
