Hello all.  I know this forum has not seen much use so I am not sure who, if anyone will see this, but I am interested to know if any of you track ro could easily find you ration of support staff to direct techs in your service organizations.  We are running at 16-17% which I am counting as mnagers, schedulers and internal call center support staff divides by the total service employment.  the balance being actual van driving , wrench turning techs.  I have no idea if this is good or a bit management heavy.  I realize this will differ by industry.  Just curious what other are experiencing.
