We don't
have to be mind readers about what the big bosses want
from maintenance. We just have to read the Wall Street
Journal or any newspaper business section. Big bosses
want less maintenance, big bosses want maintenance
that does not interfere with production, and big
bosses don't
want anything like accidents, environmental
violations, or fires, to get in the newspapers.
The bosses
are responding to the reality of their market places.
They don't necessarily see the retirement of skilled
maintenance workers as a core issue but they do see
the erosion of market share by competitors (both
domestic and international). Bosses are constantly
being exhorted by corporate management to lower the
unit cost of production. In many companies, if the
unit cost can't be lowered, production will be moved
to lower labor rate areas overseas or to plants with
lower overall costs.
These
conditions are the reality of the ridge road. Slow
death on one side from erosion of market share, and
quick death on the other from a plant closure. The
ridge road is a tough road because the maintenance
department is smaller and there is less opportunity
for mistakes. The consequences of any mistakes are
greater.
How do
we measure this effect?
The ideal plant is bigger (more output without
additional assets) because productive machines in a
plant may break, because machines are not run to
nameplate speeds, and a variety of other reasons.
Maintenance has an impact on many of these items and
can positively impact the others through getting
involved and lending its expertise.
The
easiest way to see this effect is to visualize your
factory with a size proportional to output.
One
measure developed to evaluate factory output by the
TPM folks is OEE. OEE (Overall Equipment
Effectiveness), which is a measure of the amount of
effective output compared with the ideal output
possible from the same plant, area, or machine. A
typical factory might have an OEE of 50% to 80%. The
20% to 50% that is left represents wasted resources.
The waste comes from breakdowns, model changes,
material problems, small jam-ups, etc. Without
spending any money on expansion, most plants could
increase their output by half of these numbers
(10%-25%).
Although
reduction in the cost of maintenance is an admirable
goal (and will be dealt with extensively in this
text), the real money is in increasing the OEE of the
whole plant.
Everything you ever wanted to know about maintenance
can be learned on Star Trek
Since 1967
Star Trek in its various forms has been a successful
US TV series. It has undergone several redesigns. The
maintenance message of the three main series is really
all you need to know!
In the
first series, the Chief Engineer was Montgomery Scott.
He was a down and dirty maintenance guy from the old
school. You would routinely see him crawling around
the engine room with weird looking tools, fixing
things. Scotty was a super repairperson with a
complement of cool tools. Over time we find out that
he is an accomplished engineer and designed the
standards that all Star Fleet engineers use. Scotty
was the 60sʼ vision of the ultimate maintenance guy.
Scotty is paternal, tough, and competent.
In Star
Trek, The Next Generation, the Chief Engineer is
Geordi La Forge. Geordi is blind from birth but sees
the entire Electrical Magnetic spectrum
(as well as some other cool capacities) with
his visor. In 100 episodes Geordi rarely, if ever,
repairs anything. If there is a problem, he waltzes up
to a computer console and reconfigures the Warp
couplings (or whatever). He maintains the ship
completely by computer! Occasionally when something
strange happens and the computer fails he is also the
ultimate repair guy, but this happens infrequently. We
find out that he is also a leading physicist. He is
the ultimate 90s maintenance guy using the computer to
fix everything. So Geordi is hi-tech, personable,
competent genius that is comfortable chatting up
leading theoretical physicists and can also jump in
and fix things
In the
third series, Voyager the Chief engineer is B'Elanna
Torres. Her ship was swept into the Delta quadrant
(very far from home, it will take 70 years to get
home, even at Warp 10) by Q (a childish omnipotent
being). Her ship has some biology built in so it can
repair itself. So unless they were attacked or run
into some weird anomaly in space (which does seem to
happen pretty often) the ship itself can fix most
things. Ms Torres spends most of her time trying to
coax a little more power from the Warp engines to get
home faster. B'Elanna
is the ultimate 2000's
maintenance person, no longer in the repair business
but in the business of increasing output. She is
powerful, loyal, passionate, and competent but is
focused on the productive output not the repairs or
maintenance at all.
We in
maintenance contribute to the success of the
organization. Our efforts can place the organization
squarely in the middle of an admittedly narrow path.
The goal of maintenance (like Star Trek Voyager) is
eventually to eliminate the need for maintenance
departments! The goal of maintenance is to do
everything in its power to increase the quantity and
quality of production, and reduce costs.
