Structure or People
I remember talking to a consultant a while ago who had a contract to go into an underperforming sporting organisation and conduct a thorough review. The review took everything into account, from governance to organisational structure. And the result? It was as close to an ideal organisation as possible. But it was underperforming. So the next stage of the review was to look at the personnel, which is where they discovered the problem lay.
The point? In the end, structure is important but people matter.
