Dr Philip Pearson @respirologist, a consultant respiratory physician at Northampton General Hospital and lecturer at Leicester Medical School, makes the argument for why thought diversity can save the NHS over a £1bn each year, without any form of cost-cutting.

Thought diversity, he says, is essentially the same principle as the Japanese technique known as kaizen teian; best associated with companies like Toyota. By valuing the contribution of all employees, lots of little changes can have much more of an effect than big change programmes.

It’s a simple argument, but it’s good to have it spelt out in a clear manner; the challenge now is how to implement it and allow staff the opportunity to make those changes. What do you think?
