I saw this image where there are nine managers, one supervisor, and one guy doing all of the work on a project, and something about it rang true. I've worked in two organisations that attempted to implement a matrix style of project management.
I've seen this go very wrong, with both places ending up with nearly equal hands off headcount to hands on.
How can this be avoided? What can management do to avoid an organisational structure where there is too little leadership and too much management in comparison to those tasked with the work? What checks and balances are required?
