Non Tech vs techs ratio
The Focus number is want is the ratio of non-technicians to technicians.
Your Shop Has a full-time manager (or owner who works at the shop full time), a full-time service advisor, and a part-time helper who takes care of maintenance at the facility and works about 20 hours per week and you have two full-time technicians,
So, they have 2.50 non-techs and 2.00 techs.
2.50 ÷ 2.00 = 1.25
The number of techs: The number of employees who spend most of their time servicing vehicles in some manner including tire and lube techs. Count part-time techs as the appropriate fractional number.
Example: A tech who works 3 days in a shop that is open 5 days would be counted as 0.6.
Non-techs: All employees who work at the shop, but do not fit the definition of a tech
So, our key number is 1.25:1.00
The Goal is between 0.75 : 1.00 and 1.25 : 1.00
