Every company has a skeleton and a personality. The skeleton – who reports to whom, how work is divided, where decisions happen – is its organisational structure. The personality – how people think, interact, and make sense of their world – is its corporate culture. When a business crosses borders, both skeleton and personality are stretched, bent, and often reshaped. Getting the fit right can turn cultural complexity into a powerful advantage; getting it wrong can breed confusion and stalled projects. This chapter shows you how structure and culture interlock, and how global firms use that relationship to thrive.
