than 50 percent in less than one month

All too often, businesses try to improve
performance by "implementing" improvement programs. Unless these
programs are focused on specific measurable and observable results, they are
short lived. Why is that? Human nature clashing with the world of business.
Getting people to quickly embrace change while achieving sustainable business
results can be challenging.
Well, here is a real down-to-earth success story
that shows how to focus on results and change the culture along the way. The
subject plant is a very large manufacturing facility that operates seven days,
24 hours. It is part of a multi-national corporation producing a common product
worldwide. With many of the traditional cost-cutting, down-sizing, and ISO 9000
programs well behind them, they noticed little improvement in their bottom line.
In fact, their equipment performance and reliability was declining at a steady
pace. Something had to be done, but the cost of doing "something" was
a real issue. They asked repeatedly, "How can we be assured that this Total
Productive Maintenance/Manufacturing (TPM/M) approach will address the issues
and give us a significant return on our investment?" Thats the right
question. They had to see the methods and results without taking a massive leap
of faith.
The approach they took was focused, rather than a
widespread implementation. First, they sponsored a day-long session to teach the
fundamentals of TPM/M to operations, maintenance, technical and plant
management, including about 50 salary and hourly leaders. At the end of this
session, a smaller group brainstormed possible applications and approaches,
keeping in mind something had to be done to improve the performance and
reliability of their equipment.
Within the next few weeks, they invited me back
for a plant tour and meetings with potential TPM/M starting points. They looked
for signs of equipment problems. They discussed equipment history and
performance data. They looked at the preventive and predictive maintenance
methods. The shops and spare parts conditions were reviewed. Lastly, they
discussed plant process flow and the constraints or "bottlenecks." It
was unanimous. There were two major constraints, and the most troublesome was
about to get worse after January 2000 because of market demands. In fact, there
were four of these machine cells, each one identical to the others. This was to
be the TPM/M starting point. The discussion also pointed to the next constraint
to address when the first one was cured.
After some preparation, the company assembled a
"Pit Crew" to learn and apply the elements of TPM/M to one of the four
constraint machine cells. The "Pit Crew" included a mechanic, an
electrician, a lead operator, the maintenance coordinator/planner, the area
supervisor, the reliability leader for the department, the department process
quality technician, and the area-manufacturing manager. If the reliability and
performance of this constraint was to improve, this was the group that had the
responsibility and the authority to do it.
Three days of "TPM/M Pit Stop" training
included a blend of classroom theory, case studies, demonstrations, and hands-on
application. The group had full access to the equipment each afternoon during
the training. During the hands-on portions of the training, real-time root-cause
analysis was learned and performed on all of the chronic equipment problems.
With the root causes of poor performance known, it was a matter of using the TPM/M
learnings to eliminate the causes and then establish countermeasures to ensure
they would not return. The group then applied the proven practices and
improvements to the remaining three machine cells.
After one full month of operation, the bottleneck
no longer existed. The results to date: 89 percent reduction in downtime-causing
contamination, more than 50 percent reduction in unplanned machine downtime, and
less operator intervention to free jams. This new machine performance and
reliability led to increased production throughput of nearly 250 percent per
shift of operation. Additionally, work requests now have correct machine and
part nomenclature and work orders have meaningful information on the causes of
problems. Operators have visual procedures and guides to assist in performing
their tasks. The Pit Crew continues to meet weekly to address other machine
issues and to complete the remaining improvements. A return on the investment in
TPM/M Pit Stop training was conservatively estimated at 20 to one in less than
two months considering improved production throughput and reduced maintenance
calls!
The key learnings from this example?
Focus on results and change the culture along
the way.
Build on the sub-optimized systems and
methods already in place.
Involve those who have not only the
responsibility but the also the authority to make the necessary changes.
Formally train the group using sound
adult-learning principles: Adults learn by doing and they learn what they can
apply to make their work easier.
Do things that make the equipment easier to
operate, easier to maintain, and easier to inspect.
And most importantly, focus on the
constraints in the process the high maintenance cost, high maintenance
downtime, problem-prone equipment equipment that if it improved would get
the attention of many people at all levels in the organization.
Oh, one last point: Not only did they improve one
of four machine cells in their plant within a matter of a few weeks, but there
are nearly 150 similar machine cells in the company, all with the same design
and chronic problems. If the company can standardize the minor equipment
improvements alone, just imagine that return on investment!
