Something
good up its sleeve
Dunlop
golf ball plant makes proactive maintenance a key driver
by
Paul V. Arnold
Golf has much in common with
plant maintenance.
More than 20 million Americans
play golf each year, but 80 percent of them don’t regularly shoot a
score less than 100.
If you golf, chances are great
that you’re a hacker — a recreational golfer who spends most of
the round in the woods, deep grass, ponds and bunkers.
Consistency is lacking; frustration and lost balls are
plentiful.
In the manufacturing world,
nearly 400,000 plants are located in the U.S., but a large majority of
their maintenance departments (is 80 percent a stretch?) don’t
regularly perform in a proactive mode.
If you work in maintenance,
chances are great that you’re a firefighter — a mechanic or
manager who spends most of the day in broken machines and people’s
faces. Mechanical
consistency is lacking; frustration and lost production time are
plentiful.
Dunlop Slazenger is doing what it
can to address both situations.
For the hacker, Dunlop’s plant
in Westminster, S.C. (the only site worldwide that manufacturers
Dunlop, Slazenger and Maxfli branded product), makes 384,000 golf
balls each day, 96 million annually.
So, don’t worry. No matter how many balls you shank, your local sporting goods
shop won’t run out of the little white devils.
For the maintenance worker at
that plant, significant changes were made in the way that department
is structured and functions. The
result is less running out to fight fires, and more analysis,
communication, foresight, value and throughput.
Dunlop is driven to succeed.
In
the rough
Author Lawrence Martin offers a
nine-step program to golf improvement in his book, “Why Are You
Still a Hacker?” Step 1
is admitting you’re a hacker. For
the Dunlop plant, maintenance improvement began when it acknowledged
its firefighting ways.
“Maintenance didn’t bring
value to the plant other than ‘fix it when it breaks,’” says
Katherine Sitler, the strategic planning and operational support
manager.
Says maintenance planner Jason
Barnes,“We were a reactive organization.
Nothing was planned. We
had more than 20 guys who just did emergency breakdowns.”
Tradition, psychology and plant
environment fueled the firefighting culture.
“I’ve been in maintenance at
a lot of places over the past 30-plus years, and this plant was no
different from most anyone else,” says Jerry Henson, the director of
engineering services. “When
things break down and you are capable of bringing it back up quickly,
there are feelings of accomplishment.
You are the hero saving the day.
Many people live in that world and enjoy it.”
Like most U.S. plants, a
separation between maintenance and operations kept a reactive mode in
check.
“The feeling from operations
was, ‘I don’t want to see you unless the machine’s broken,’”
says Sitler. “There was
little cooperation from either side.
When the machine went down, maintenance came to fix it and the
operators went on break.”
Maintenance was “the necessary
evil” unless it was taking care of an emergency call.
New
VP plays through
Step 2 in Martin’s golf book is
“Commit to improvement.” Vice
president of manufacturing Greg Gianforcaro provided the necessary
commitment and game plans when he came to Dunlop from Scott Paper in
2000.
“Greg brought a vision of what
he thought maintenance should do and what role it should play,” says
Sitler. “He envisioned
the maintenance technicians and operating group working together as a
team to ensure that the equipment is available when you need it.”
Who is the “you” in “when
you need it”? There is
a reason for that ambiguity. No
doubt, operations needs the machines to get product out the door.
But maintenance would need access, too, in order to monitor
machine health and perform tasks that reduce or eliminate the chance
of costly breakdowns.
Gianforcaro sold maintenance
leadership on that proactive thinking, and formal preventive
maintenance (PM) tasks were added to the workload in late 2000.
The early results were mixed.
“It really helped us in
maintenance evaluate what we were doing and what the benefits could be
if we changed,” says Sitler.
But change brought uneasiness to
some maintenance technicians.
“There was an element, I
don’t know if fear is the right word,” she says.
“Shifting away from firefighting, the feeling was, ‘Does
this mean I’m not important anymore?’”
There were other issues, as well.
Communication between maintenance
and operations needed fixing.
“None of the PMs were done
through planners,” she says. “We’d
show up and the machine would be running wide open.
Operations would look at you and be like, ‘What are you doing
here?’”
The PM process also needed a fix.
“We didn’t have a good method
of writing PMs,” says Barnes. “A
PM didn’t include inspecting every little part on the machine.
It didn’t break down specific machine components.
It was just generic.”
Maintenance technician buy-in
would come with time and results.
The communication and process
faults were addressed in early 2002.
First, Barnes, an electronics
technician, was named the full-time maintenance planner.
He now works with operations’ scheduling department to
coordinate PM tasks.
“They get a PM schedule a week
or two ahead of time,” he says.
“Based on that, they schedule what machines are going to run
what product. They have flexibility to move some of the products from
different machinery around our schedule.
If they have problems, they have enough time to call me. We can then take our maintenance list and adjust.”
Second, meaningful and consistent
PMs resulted from adopting Reliability-Centered Maintenance (RCM), an
initiative Gianforcaro championed while at Scott Paper.
Analyzing
the swing
Step 3 in Martin’s golf book is
“Take lessons from a pro.” Step
4 is “Understand ball flight.”
Dunlop got instruction from Doug Plucknette, a consultant who
formerly led the RCM program at Eastman Kodak.
He helped plant employees get a better understanding of their
machinery.
RCM involves closely examining
individual machines (and their components) and identifying the
potential risks, failure modes and solutions to enhanced reliability.
It revolves around asking seven basic questions:
1) What are the functions and
associated performance standards of the asset in its present operating
context?
2) In what ways does it fail to
fulfill its functions (failure mode)?
3) What causes each failure?
4) What happens when each
functional failure occurs?
5) In what way does each failure
matter?
6) What can be done to prevent
each failure?
7) What should be done if a
suitable preventive task can’t be found (default tasks)?
An RCM Blitz team — a four- to
six-person group consisting of maintenance technicians, engineers,
managers and operators (remember Gianforcaro’s call to work together
as a team?) — is responsible for getting the answers to those
questions.
“The Blitz team decides on the
best way to address the asset,” says Sitler.
“Is it through a detailed, meaningful list of PM
instructions? Some
predictive maintenance work? An
engineering redesign?”
Barnes says PMs are now the
result of “what the team sees, what operators say, what technicians
have worked on and what the managers discuss in meetings.”
Seventeen RCM blitzes have been
done to date, and the results of each have been impressive.
As an example, one Blitz team
spent five days (eight hours per day) examining a buffing machine that
removes a seam incurred in the ball’s injection-molding stage and
sands the object in preparation for painting and stamping.
“We broke it down to three main
components and did an analysis on them,” says Henson.
“The team got a whole new awareness and understanding on what
this machine did and how it could be maximized.”
The examination revealed
opportunities and potential cures.
“One of the problems we used to
have was bearings going out on the machine’s spindles,” says
buffing operator and Blitz team member Cheryl Gilliam.
“When the bearings went out, they made a bad buff on the
ball. Sometimes, it would really destroy the ball.
Since we’ve begun the new PMs, we haven’t had nearly the
trouble we did before. It
also improved quality and throughput.”
Throughput on the machine is up
26 percent since installation of the team’s corrections.
“That number — 26 percent —
turned heads and got people excited,” says Sitler.
“Seeing what took place, people know that when they
participate, they can make a difference.”
Eyes
on the green
Steps 5 through 7 in Martin’s
golf fix-it manual involve proper setup and effective greens
strategies. The Dunlop plant mirrored those steps when it toppled the
remaining barriers between maintenance and operations.
Gianforcaro’s vision of “the maintenance technicians and
operating group working together as a team” became a reality when
maintenance was spun off into two groups.
In the new setup, 11 of the plant’s 40 technicians remain in
the “central” group and 29 reside in a hybrid “embedded”
group.
Central technicians perform
full-time maintenance activities — PMs, machinery upgrades, repairs
and rebuilds — around the plant.
“The majority of our
best-skilled, top maintenance guys are in this group,” says Henson. “That allows us to get the most of the minimal number of
people we have.”
The embedded employees spend 80
percent of their time devoted to one particular production area. For the four days a week they work in this area, these
technicians do as much production work as they do maintenance work (PMs,
repairs and adjustments).
“They do many of the
higher-skilled jobs there,” says Sitler.
“They are responsible for running the injection-molding
machines. Some prepare
and operate the large presses. Some run the paint system.”
The other 20 percent of an
embedded technician’s time is spent working out of the central
group.
The benefits have been twofold.
“The relationship between
operations and maintenance improved because the embedded guys are
there; they are involved with them most every day,” says Henson.
“It’s led to understanding and a better flow of
information.”
It also helped the plant stay
competitive in the global marketplace.
“Costs are important,” says
Sitler. “If your
maintenance processes are working, there isn’t something that needs
to be repaired or worked on 24 hours a day.
You can use your maintenance people in other ways that help you
be more productive and achieve lower overall costs.”
While some embedded techs would
prefer not to split their schedule — “They’d rather work on the
car than drive it,” quips Henson — most are economic realists and
also have enjoyed the extra attention from operations.
“Operators love their embedded
technicians . . . to the point where they don’t want to share them
with others,” says Sitler.
Says
R.L. Webb, a technician in
the central group, “Thanks to the embedded setup, I think we’re
looked up to a little more than in the past.
They’ve gotten to know us on a different level.”
Making
the cut
Step 8 in Martin’s book is
“Practicing with a purpose.”
Dunlop incorporates this into its maintenance initiative by
constantly seeking ways to build the skills of its people.
A firefighter only needs to know about repair techniques.
A proactive technician must be well-rounded.
The department, led by
maintenance manager Tim Hopper, is building a skills development
matrix in which personnel receive formal, multiple-level training not
only in advanced maintenance techniques, but also in business, people
management and computer skills.
“We’re raising the bar,”
says Henson. “We want
people who go out there to solve a problem, not to replace a part, and
to provide a benefit to the customer.
We want people to use their brain to analyze the issues, focus
on the root causes and resolve them.
We want to change the attitude to more of a professional,
customer service-oriented environment where the customer is happy to
see you. You are there to
provide value and a benefit.”
The
leader board
Martin’s golf book on
transforming a hacker concludes with Step 9, “Play often, and keep
score!” Dunlop maintenance keeps score (and documents its shift away
from firefighting) with a variety of metrics that display the impact
of its structural and philosophic changes.
A successful transformation can
be found in the following facts:
• Barnes says more than 400 PM
tasks are now effectively managed.
The percentage of completed PM tasks currently exceeds 90
percent and is closing in on 95 percent, a sharp rise from the 85
percent it posted just two years ago.
“On equipment we traditionally
had problems with, the frequency of failure is much less,” says
Henson.
• In the first half of 2004,
planned work orders exceeded unplanned work orders by a 2-to-1 margin. That’s a big turnaround from 2000, when there was little
planned work.
“Emergency work orders have
significantly decreased, and it continues to go down,” says Henson. “The reliability of the equipment has increased
substantially.”
• The metric “maintenance
cost per dozen balls produced” shows a major drop — from a high of
77 cents in September 2003 to 24 cents in both May and June of this
year.
“Our guys want to get it done
right the first time and look for ways to improve the process,” says
Barnes.
With consumers having an
insatiable appetite for Dunlop’s family of golf ball brands (the
plant has posted off-the-chart production numbers this year), the
company has needed the extra efficiency, uptime and throughput.
While there’s no time to rest
on its laurels, maintenance can at least smile and show its dimples.
“We’re on the journey,”
says Henson. “We know
where we want to go and how to get there.”
Looking
'fore'-ward: Taking advantage of PdM
The Dunlop plant’s maintenance plans for 2005 call for
expanded use of predictive maintenance (PdM) tools. For the past
few years, the department has utilized outside suppliers to take
infrared thermography scans and vibration readings. However, it
recently purchased its own PdM tools and plans to put them in
the hands of maintenance technicians at some point next year.
“We
have vibration analysis, infrared cameras and alignment tools
now,” says planner Jason Barnes. “Training must take place,
though, before we use them.” |
