Develop a New Generation of Leaders

We must develop a new generation of leaders who can communicate their vision and drive change in culture and behaviour

Adopt New Business Models that Promote Change

Business models are fundamental to changing behaviour. We must move away from models that encourage short term thinking and find ways to incentivise long term value creation

Procure for Value

All customers in the chain need to professionalise their procurement to achieve best value, rather than focusing on lowest price.

Andrew Wolstenholme October 2009
