On the first of these there is probably a largely positive self-correcting process at work. Organisations that have an unexpected crisis-implying the failure of previous leadership and the leadership development behind that - are more likely to look for a new approach and to introduce it newcomer able to see thing with fresh eyes. Organisations with an ongoing history of success are more likely to use the time-served insider who has a feel for the dynamics of the continuing success. There are dangers either way - throwing babies out with bathwater with the or failing to see new kinds of upcoming challenge with traditional approach, or indeed the fear of changing anything through lack of certainty about what is maintaining success.
