 The critical component in driving successful transformation through leaders is to have all leaders own the transformation. So there is a Chief Transformation Officer, but everybody needs to feel the same level of ownership to transform the company. The critical way that we've been successful in driving that is to understand what the North Star is, understand what the, if you like, not quite the end point, because transformation's never end, but understand very clearly where the strategy will drive your organisation and then have each leader within each function understand what they need to commit to and execute against to make that successful. One of the things that we've done very successfully is marry the role of the Chief Operating Officer and the Chief Transformation role together. What that allows is the strategy around digital transformation to basically be taken to be owned, developed, but also pushed all the way through into operational execution. We describe this as an enterprise L-shape, so it comes from a strategy into horizontal execution across all functions. That's been enormously successful in driving that continuity of experience through digital transformation.
