To me this is a key change in a direct reports development.
When they first start they need to be told what tasks to do; then they develop to asking for permission to do tasks that find or know need to be done; and finally they are telling me they are doing a task so I know we are going in the right direction. These changes give much better autonomy within the team and I am know longer the blocker to progress. It also means I can get on and do more interesting tasks myself while working with the junior members of the team.
