Hi,
Looking at these different types, the last one in particular stands out to me for certain reasons. First, the fact that the directorate have an influential vision that is applied across the company and its different branches. This circular organization also allows for sharing of workload and responsibility between different divisions of the workforce and a great deal of flexibility between them. Through this it seems as if middle management will be immersed into the actual “work” if you will as much as possible. This is done by eliminated departments and divisions but instead teams and groups of people to work on assigned tasks at a time.
