How many process drivers can a manager supervise

In specialized literature and in practical application, we encounter so-called control margins - what a word - of 10 to 15 individuals. With regard to the actual status you should ask  

Whatpercentage of their working time does senior stafk(e.g. foremen) dedicate to the technical direction andpersonal coaching of their valuable employees  

Commonly, this percentage is estimated at 10%. If you cannot imagine this to be true, ask one of these foremen when he was last able to hold a well-prepared personal development meeting with one of his hopeful employees without interruptions during a day s work  

What is there to stop the foreman today from investing 100% of his time in his employees He does not have the time because he constantly has to make sure that at least the most important deadlines are met. 

In the new organization, those responsible for personnel are no longer responsible for deadline control. And even worse they are not even allowed to touch the work on hand lists synchronized between the SCM and expert groups.
