Maintenance is not a departmentby
Robert M.
Williamson
Modern business has organized itself
into a very non-competitive position. In most manufacturing plants and facilities, there
are numerous "departments" with their own organizations and budgets. A
maintenance department is often one of those. Unfortunately, maintenance is not a
department. Maintenance means "sustaining; preserving good working order, optimum
condition or a level of performance," not being on call to fix things. All too often,
the maintenance department is looked upon as the sole maintainers of equipment,
facilities, processes and buildings. They can't do it alone anymore.
Equipment has maintenance problems,
and the company has a department. Now is the time to refocus modern business on addressing
maintenance problems regardless of the department structures, sharing responsibility for
truly maintaining equipment, facilities and buildings.
One of the plants we are observing has
operated for more than 20 years with a "fix-it" mind-set and a maintenance
department with a tight budget. Today, for example, they have three air compressors, two
of which operate to supply air to the thousands and thousands of small air leaks
throughout the plant. This condition didnt just happen overnight. It took 20 years
of a typical maintenance approach fixing things that break and tightening their
budget to get there. Their reliability engineer estimates they budget and spend
more than $200,000 each year to operate and maintain these compressors just to supply air
to the leaks. Add to that cost the initial capital investment for those extra compressors
and the ongoing electrical usage. This represents a controllable expense that the
maintenance department was helpless to address because the air leaks are located in the
production departments and are not seen as a maintenance problem.
In this plant, the maintenance
department mind-set is beginning to change. The "maintenance department" was
restructured with "reliability leaders" responsible for each of the primary
manufacturing areas. Maintenance managers and their skilled planners and crews now have
responsibility for defined areas of the plant. Fourteen months ago, they engaged
production and maintenance management along with maintainers, operators and process
quality people to focus on improving the performance and reliability of one of the plants
most critical constraint processes. It worked!
Performance and reliability
improved significantly and has been sustained for nearly 14 months. These new maintenance
methods have also begun to spread to other similar processes. The results:
availability continues to climb
production throughput more than doubled
fewer operators are required
maintenance costs declined nearly 16 percent
a capital project to add another machine was cancelled
maintainers and operators have more time to focus on preventive maintenance of
their critical equipment.
Surprisingly, these improvements
aren't the most significant. The plant now has production management in four different
areas applying the same team-based maintenance techniques to their critical processes. A
sense of ownership is emerging because production and maintenance are working together to
eliminate the causes of poor performance and reliability in sustainable manners. The plant
manager is whole-heartedly endorsing, encouraging, and in 2001 holding the production
department leaders responsible for this new maintenance and reliability strategy as part
of their business and performance objectives. Their work culture is changing. Wonderful
things begin to happen in a work culture when maintenance ceases to be a
"department" and emerges as a "responsibility" that everyone shares.
In addition to the significant
tangible results, there are numerous intangibles:
Communication improves between the maintainers and the operators.
Better understanding of the equipment functions develops.
More minds look for ways to make the equipment easier to operate, inspect and
maintain with fewer problems.
These intangibles obviously lead to
more tangible performance results. This is proof enough that operating costs will reduce
and performance will improve when more business leaders learn that maintenance is not a
department but rather a shared responsibility to preserve equipment, building and facility
condition.
