Big organisations have things which aren’t quite anybody’s job to do, so they don’t get done. Small organisations tend to solve that problem partly by making everybody’s role much more fluid, and partly by reducing the overheads of the collective action problem. Big organisations find that hard because they manage complexity through structure – which is fine for things which go with the grain of the structure but can be very difficult for things which cut across it. That can lead to situations where – in a neat phrase from this post – ‘the indecision is final’. The solution advocated here is a simple one: if spaces are unoccupied, occupy them.
