Technician efficiency

Fullbay's 2022 post on efficiency and productivity writes the same formula, "invoiced hours" over the hours worked for its "efficiency percentage", and a shop owner in a 2014 AutoShopOwner thread on tracking billed against worked hours put it as hours billed divided by the actual hours spent on jobs. The numerator is the hours sold, the flagged hours. The denominator is the time the technician spent on those jobs with the clock running. Efficiency can only be computed where the clock runs on the job line, because a time clock that knows the technician was in the building and not which job they were on gives productivity, not efficiency.

As an example only: a technician who flagged 44 hours in a week and clocked 40 on those jobs is at 44 ÷ 40 = 1.10; one who flagged 32 against 40 clocked is at 0.80.

What it does not measure: the unbilled time between jobs, which is productivity's job; and whether the hours sold were right in the first place, which is the shop's pricing. A technician at 1.30 on a job sold at too many hours has done nothing wrong and the shop has overcharged; a technician at 0.70 on a job sold short has done nothing wrong either. The figure is only as honest as the hours on the line.

In Wrenchy the clock runs on the job line, with start, switch, stop and undo from the order, which is what makes the denominator exist. The labor rate calculator uses the same two figures for the effective rate.
