Maintenance
Efficiency:
Understand It
To Drive It
Various factors and measurements affect an
organization's ability to improve workforce efficiencies.
Critical factors
Numerous factors influence effective
use of maintenance labor resources. At
the top of any list, however, is a welldefined maintenance-work process.
This type of process describes, in
detail, each step of maintenance work
from identification through execution

and closure. Despite claims to the
contrary, there is effectively only one
universally used maintenance work-
flow. The five major components are
identification, planning, scheduling,
execution, and closure:

IT'S A GIVEN: Maintenance is the
largest fixed cost in manufacturing.
Maintenance-workforce efficiency has a
profound effect on that cost and, in turn,
overall business performance. Can that
efficiency be improved and, if so, how?
The common metric used to measure
this efficiency is wrench time. Research
on wrench time has revealed maintenance workforce efficiencies ranging
from 18% to 74%. In other words, inefficient maintenance operations will spend
exponentially more on maintenance
labor than the most efficient operations
to complete the same amount of work.
To illustrate the significant financial
impact of maintenance workforce efficiency, a highly efficient operation with
74% wrench time spends $100 million/
yr. on maintenance labor. A highly
inefficient maintenance operation would
spend more than four times that amount
(or more than $400 million annually)
to complete the same volume of work.
Translation: The inefficient maintenance
operation would waste $300 million a
year due to inefficiency.
