We live in uncertain times and with conflicting visions of our future. Right now it is as difficult to predict what will happen to the private sector as to the public sector. Amid the diverse predictions, there is but one constant – the overwhelming likelihood of change.

But, when it comes to public services, so many people are in denial. Change is unpopular. The NHS is discovering that long-standing patient pathways remain popular even when safer and better services are available. The police are in rebellious mood, and local authorities are fending off unhappy residents who are unwilling to suffer closures or service rationalisations.
