In a large organisation such as Unilever, how do you help colleagues integrate the sustainable growth model into their day to day work activities? How do you go from broadcasting to interacting? Anniek Mauser talks about it in an interview with Communicatie Magazine (in Dutch): about behaviour change with the Five Levers for Change model, about the role as champion of CEO Paul Polman, about her role as ‘Chief Challenging Officer’, and about internal engagement of employees and the role of the web-based engagement tool which Kairos Tools (now: Snowballs & Flywheels) developed for Unilever.
