John Prescott is never short of an opinion or two but his spat with David Miliband shows that political parties deal with leadership change in a very different way to businesses.

Businesses prefer to keep things quiet and within the organisation. Whereas Labour is having an open and frank debate, businesses often look to outside for a different approach. It is normally assumed that continuity comes from inside but they need to go outside for change.

There are always exceptions but the question could be asked whether a closed approach is preventing organisations from hearing good ideas and potential innovation? Why can't change come from within? If it can how do they best hear those voices?
