Why Manage Maintenance?
Maintenance costs continue to capture the attention of senior
management as the investment and reliability in assets become
increasingly greater. Over the past twenty years, we have witnessed
the recognition of maintenance
as essential to the core business operations.
However, most companies fail to adequately define the role and
operation of maintenance within the business enterprise. Experience
suggests that in many cases, maintenance continues to be a cost
of doing business, and as such, treated just like any other budget
line item it increases or decreases as a percentage with
disregard to impact on operations or what is truly needed. So
why should we manage maintenance as a business? The answer is
quite
simply, because it is a business; in fact, it is a service business.
Looking at todays enterprise we see that direct costs have
become identifiable and manageable as a result of managements
focus and attention.
To this end, numerous business processes, systems, policies and
procedures have been implemented to assist in this endeavor. However,
we also find that maintenance costs are becoming a larger percentage
of the total cost of
conversion (excluding direct materials). For example, one company
recently identified their maintenance cost as in excess of 40%
of their total cost of conversion, representing a significant
opportunity for improvement.
So
why should we manage maintenance as a business? The answer is
quite simply, because it is a business; in fact, it is a service
business.
The real question still remains as to how we approach
managing the maintenance function. All too often the answer to
this question is to
strictly implement a Computerized Maintenance Management System
(CMMS) without considering the required, complimentary processes.
This becomes the panacea for the effective and efficient use of
maintenance
resources. Many managers accept the philosophy that the system
is the solution and fail to recognize that the real solution is
in the process.
But, how can one define the right processes without first defining
the why and the where? Doing things right or doing the right things!
The benefit opportunities associated with sound
maintenance management have been identified and documented for
years. Unfortunately, over
the last twenty years, few companies have realized these benefits.
In a recent study focusing on maintenance management benefits
conducted by the management consulting firm of A.T. Kearney the
conclusions ring all too
familiar:

Additionally, benefits accrue in the areas of reduced
spare parts obsolescence, reduced maintenance overtime and improved
quality. In
a recent poll conducted by The Copley Consulting Group, CMMS users
were asked to articulate the benefits of maintenance management.
Most respondents concluded it was all the information that was
collected which was of value. Asked what was done with all this
information, there were differing views. Do the words information
overload mean anything?
What was concluded from this exercise was the fact that the focus
clearly was on implementing a CMMS and the information by-product.
The
benefits, however, could not be achieved without defining and
implementing the requisite business processes and using the CMMS
as the enabler or tool as a facilitator.
Perhaps if we briefly examine where we have been
regarding maintenance management, it will enable us to adequately
define where we are going, and how we are going to get there.
As we will realize, without having an accepted maintenance
strategy, our maintenance management approach may not yield the
desired or expected outcomes.
Prior to 1970, there was little focus on identifying
and managing the maintenance function. The primary focus was on
direct manufacturing,
operations and materials; generally, maintenance was looked upon
as a cost of doing business. During the period from 1970 to 1980,
there was more focus on documenting maintenance as it relates
to preventive maintenance
and equipment uptime. Also during this time, there were initial
attempts to define and establish business processes supportive
of maintenance as a business further enhanced by the development
of computer tools. Maintenance planners and schedulers were becoming
necessary to properly organize the maintenance function. As we
moved into the mid 1980s
there was an increasing focus on preventive maintenance as well
as predictive maintenance. The concept and practice of Total Productive
Maintenance (TPM) began to receive attention and become implemented
which involved the self directed work force. Finally, as we sit
here today, we are refining the concepts of event driven and reliability
centered maintenance achieved through self directed work teams.
The practices of rationalizing inventories and designing for maintainability
are becoming
realities. So, where do we go from here? Before we go anywhere,
lets determine what we want this maintenance business to
be. Or what do I
want to be?
Determining a Maintenance
Philosophy
It is probably safe to say that most people think of
the maintenance
function as:
- Fixing things that break
- Keeping things looking good or
- Keeping things from breaking
These thoughts are not necessarily inappropriate. However, if
we are to structure our maintenance business we should ask some
additional
questions such as:
- Do we staff and supply to only address breakdowns?
- What is the cost of equipment downtime?
- How much time is needed to perform routine recurring maintenance
activities?
- Should we be focusing on activities to reduce breakdowns or
should we just let the thing break?
It is interesting to debate the merits of preventive (PM) versus
predictive maintenance (PDM) as to where a maintenance focus should
be. It is worth noting that either one is better than none at
all. There is a certain truth to the fact that a PDM program may
be more cost effective due to the fact that the equipment is being
maintained when it needs to be rather than when its
time to. If you accept this rationale, then why do many of us
change the oil in our cars every 3000 miles rather than when an
oil test would reveal when to change? The point of this example
is to demonstrate that biases exist which
must be addressed in order to properly determine the direction
of the maintenance business.
It is interesting
to debate the merits of preventive (PM) versus predictive maintenance
(PDM) as to where a maintenance focus should be.
If the automobile manufacturers were to provide us with an idiot
light to signal us of the oil condition, would we still be so
inclined to take
the car out of service before we had to? Just as in this example,
when attempting to define the role of maintenance management,
it is essential
that the needs of the maintenance customer be addressed and satisfied.
Lets define the maintenance customer as the individual or
group who requests maintenance services. Take a moment to identify
the maintenance
customers in your enterprise. In most cases the maintenance customers
are production departments, facilities, operating departments
and administrative groups. Each maintenance customer may have
unique expectations
and requirements regarding maintenance. If one would attempt to
reach a consensus it would be that all customers desire timely
quality service
at a fair price. Value! No different from what we would expect
from the mechanic for our car or the teller in the bank. Maintenance
provides a
service!
Ask yourself
this question: If the maintenance customers were to pay for only
what they receive, what would they pay? If the answer to this
question is Whatever it costs, there is a real problem!
Understanding the needs and expectations of the maintenance customer
is critical to establishing the maintenance business processes.
Ask yourself this question: If the maintenance customers were
to pay for only what they
receive, what would they pay? If the answer to this question is
Whatever it costs, there is a real problem! Service
businesses are discovering
that customers do have limits when it comes to timeliness and
costs but there is no compromise when it comes to quality. Take
an extreme but
real example: You are about to undergo open heart surgery and
you have a choice of the surgeon to perform the operation. You
can choose an experienced doctor who has performed the procedure
hundreds of times, or
you can choose a doctor who has only performed the operation several
times. The highly experienced doctor charges twice what the alternate
doctor charges. Whom would you select? Note that you, the customer,
are not willing to compromise on the quality of work and as a
result you most likely would select the more experienced doctor.
However, if we were
to now say that the operation is a simple operation such as a
hangnail removal, are you willing to pay twice as much? In an
effort to address
the cost issue, the medical and insurance communities have come
up with Diagnostic Related Groups (DRG) for reimbursement and
billing. Considering this example, are maintenance customers willing
to pay for whatever it costs or are they willing to pay for the
value they receive?
Defining a Mission
As in any business, the maintenance business should have its own
mission that reflects how the business will address the needs
of its customers.
The need for a mission statement is embodied in a guiding premise
relating to the purpose of maintenance activities. The mission
statement is the basic statement of the reason for the business
existence that distinguishes one business from other similar businesses.
It defines the basic product or service and the primary customer
groups.
Defining the service in a maintenance business is not as simple
as it appears. Not only is the type of service necessary to define,
but also the time frame in which the service will be provided.
In attempt to define the types of services
lets consider the following:
- Is the equipment regularly available to perform planned/routine
maintenance activities?
- Will the cost to shut down the equipment be less than the
cost of failure (breakdown)?
- Is equipment downtime a problem?
In one sense, the answers to these questions can lead us to organize
merely for demand maintenance at a given response level. For the
seasoned professionals, this was usually addressed through MOD
(Maintenance On Demand) Squads. Staffing requirements in this
situation are clearly different from those involving significant
levels of deferred maintenance activities. Thus, the mission statement
should reflect this type of service in addition to a
delivery time frame. Clearly, this must be consistent with customer
expectations. If the maintenance customer expects immediate service,
regardless of what needs to be done, then the maintenance staffing
requirements must reflect the higher cost of doing business in
this fashion. It also challenges maintenance managers to identify
alternatives such as outside
resources to supplement full time staff. If the maintenance business
mission is highly focused on proactive maintenance activities,
then an additional set of objectives, priorities and resources
are required.
Who should
develop the maintenance business mission?
Not maintenance! To be meaningful and credible, the
mission statement must be formulated by the customers in
concert with maintenance.
Who should develop the maintenance business mission? Not maintenance!
To be meaningful and credible, the mission statement must be formulated
by the customers in concert with maintenance. Usually this can
be done with key customers and a representative from maintenance.
The risk is that the mission ends up being too general. It is
important to be as specific as possible so, ultimately, the business
focus can be maintained. As the foundation on which all maintenance
goals and objectives will be built, the mission statement is the
critical element in developing an effective maintenance strategy.
Determining the Business Objectives
As in any business endeavor, objectives must be established.
Surprisingly, these objectives can be classified into long-term
and short-term objectives
or goals. These goals should represent more specific targets or
results the business wants to achieve. The goals are derived from
and must be focused on fulfilling the business mission.
Long-term goals and objectives:
- Indicate desired outcomes for a fairly long period of time
- Should be accomplished in more than one year or more than
one decision cycle
- Are more specific than the Mission Statement but less specific
than short-term goals
A decision cycle is the time it takes a decision to reach full
implementation. An example of a long-term goal might be to achieve
World Class Maintenance status. Of course, this assumes that one
of the activities would be to define the criteria for world class.
Additional long-term goals might be:
- Profitability or Cost Management
- Productivity
- Competitive Position
- Employee Development
- Employee Relations
- Technological Leadership
In conjunction with long-term goals, short-term objectives must
be established to ensure that the maintenance business is on the
right track in
fulfilling its mission. Short-term goals typically:
- Provide specific detailed target results
- Are results the business intends to generate during the
next decision cycle
- Can be accomplished within one year
Examples of short-term goals are:
- Overtime reduction of 2%
- Implementation of a PM or PDM program for a specific area
or group of equipment
- Implementation of a training program for a specific craft
or trade
- Implementation of a work order system within a given area
or for a specific trade
- Implementation of an inventory management
program
As you can see, the short-term goals must be very specific with
a defined result or ending point. It should be noted, however,
that short term goals also must reflect the fulfillment of the
mission statement.
Organizing the Maintenance Business
Knowing what the maintenance business is in business for enables
the business to organize for success. Traditionally, maintenance
organizations
have taken on several different structures. In centrally organized
maintenance operations, all functions ultimately report to a single
professional.
This structure is very effective in an environment involving similarly
skilled tradespeople and defined service areas, even though the
service areas may be geographically far apart. This maintenance
structure is common
among facilities, education, hospitality, service and health care
industries. This type of organization can yield rapid response
(a requirement
within these industries) with minimal resources.
A decentralized maintenance organization may involve deployment
of resources to specific areas as well as different reporting
relationships.
For example, in a manufacturing facility with multiple production
departments, the maintenance resources report to the production
department and not to the maintenance department. In this case,
although rapid response is achieved, there may be inefficient
use of resources
on an enterprise level. In an attempt to address the latter, a
hybrid maintenance structure can be employed. That is, specific
resources
operating in a decentralized fashion with common resources operating
in a centralized fashion. In our example, this would involve the
specifically trained maintenance trades or specialists to report
to the respective production
areas. Broad skilled trades (electricians, pipe fitters, etc.)
would report to a central maintenance organization responsible
for the assignment and deployment to the requesting production
departments. In this way, rapid
response while minimizing total resources is achieved.
Outsourcing maintenance activities may occur in total or in part.
For example, custodial activity in many industries is an outside
or external
resource. In some cases, the entire maintenance activity is provided
by an external resource (evident in facilities maintenance). In
cases of outsourcing or extremely large hybrid structures, an
oversight maintenance management
group may exist to continuously monitor and evaluate maintenance
performance.
The structure of the maintenance organization should periodically
be reviewed to assess whether it is satisfying the business mission.
As new technology is deployed, self directed work teams implemented,
and non-value added activities minimized, there can be reason
to reorganize the maintenance function. As in any business, customers
demand that the business be well managed and controlled to ensure
quality and cost effectiveness. In these changing times, organizations
must be flexible and that
requires innovative leadership. Moreover, leadership characteristics
must embrace the entrepreneurial spirit to provide the best possible
value.
Measuring the Maintenance Business Performance
In most businesses, success is easily measured by looking at the
bottom line; but, whats the bottom line in the maintenance
business? To better understand how to evaluate maintenance business
performance, its helpful to examine how businesses generate
profits. Quite simply, businesses generate profits by providing
goods and/or services at minimum cost and sold at a fair market
price. Obviously, revenues generated from sales must exceed the
costs. It is important to note that the customer determines
the fair market price. In the maintenance business, the customer
pays for value; price is part of the value equation along with
quality and timeliness. So, as we look at the maintenance business,
price is something that cannot be ignored. For example, if internal
electricians are charged to the department at $45.00 per hour
and the comparable skill for an external resource is $30.00 per
hour, it will not take long before outside electricians are being
used.
In the
maintenance business, the customer pays for value; price is part
of the value equation along with quality and timeliness. So, as
we look at the maintenance business, price is something that cannot
be ignored.
It has been presented that customers demand value. Price, quality
and timeliness are the components of value. Therefore, our performance
measures should reflect how the maintenance business is providing
value to its customers. Also, the maintenance business must develop
internal performance measurements to assess its health. First,
the external measurements.
Timeliness can be measured by average time to respond for a certain
class of maintenance activities. Many maintenance operations have
set goals for responsiveness given the nature of the work. For
example, for emergency work, a goal might be to respond within
one hour. For normal corrective maintenance activities it might
be one week. Again, these goals are
established in concert with the customers. It has also been discovered
that the type of work may not be the only determining factor;
in many cases, the equipment may determine a response time frame.
For example, a breakdown in an operating room air filtration system
is significantly
more important that a breakdown of a hospital bed. Thus, our response
goals are dependent upon not only the nature of the work but the
equipment as well. The average time to respond can be calculated
by capturing the elapsed time between request receipt and the
commencement of work. Once calculated, this measurement is indicative
of how well maintenance is satisfying customers expectations
of timeliness.
Schedule compliance is another means of monitoring customer timeliness
expectations. In this metric, the scheduled start date or promise
date of the work order is compared to the actual start date. Again,
a simple calculation of actual versus promised; either it was
started on time or it wasnt. Again, customer communications
and managing expectations are paramount.
Remember,
in the eyes of the customer, if it keeps breaking, its because
it was not fixed and therefore is a maintenance responsibility.
Quality of work is not as easily measured as timeliness. However,
quality can be measured through customer complaints, work review
and repeat work. If the customer is not satisfied, it is hoped
that the dissatisfaction will be acknowledged in some form. In
many cases, the customer is required to sign a completed work
slip accepting the quality of the work performed.
Although this is a satisfactory form of acceptance, has satisfaction
truly been measured? Perhaps the best way to ensure quality is
through a work review program where supervisory personnel review
the quality of the work
performed. These are formal programs that when properly conducted
can provide valuable feedback regarding customer satisfaction
and employee skills. A rating system is typically employed which
recognizes the quality of the work and level of customer satisfaction.
Finally, if a particular work activity is frequently being requested
it may be indicative of a multitude of
problems. Remember, in the eyes of the customer, if it keeps breaking,
its because it was not fixed and therefore is a maintenance
responsibility.
Price is always a topic for debate. How many times have you heard
If I had known it was going to cost that much, I wouldnt
have done it! or What do you mean it cost $490 to
replace that bulb!. Customers do not like surprises. Customers
demand fair pricing. Admittedly, in most internal maintenance
operations the customers find out what it costs after the
fact and not before. It is amusing that as private citizens we
would not have someone perform any work without having some idea
as to what
it might cost, and then, we may even attempt to mitigate or negotiate.
In the internal maintenance business, how often are estimates
provided?
Are there established hourly rates for providing service for both
labor and materials? How do these rates compare with external
rates? Determining price performance is addressed largely by comparing
the book rate versus the actual rate. The book rate is a blended
average of hourly labor rates inclusive of benefits, whereas the
actual rate is calculated by taking total labor dollars, including
benefits, and dividing by the hours of direct activities
(actual work time). The book rate is a quick comparison to the
outside rate whereas the actual rate reflects utilization and
rate.
Satisfying the customer is essential to any business success,
but a healthy business ensures continued success. There has been
much published
about maintenance performance metrics so they will not be elaborated
on, but to name a few:
- Preventive Maintenance Compliance
- Schedule Compliance
- Inventory Turns
- Inventory Accuracy
- Inventory Level
- Backlog Size
- Backlog Severity
- Breakdown/Emergency Analysis
- Work Distribution
- Scheduled vs. Non-Scheduled
- Equipment Effectiveness
Managing maintenance as business involves managing expectations
and balancing costs and service. Identifying maintenance cost
drivers is an important factor in the cost and service balancing
act. Maintenance costs are largely attributable to labor, materials
and contract services. Material costs can effectively be managed
and controlled through inventory management
practices, procedures and policies. Thus, we can reduce the volatility
of the balancing act by concentrating on labor and contract services.
What drives labor cost is simply a matter of supply and demand.
The demand portion is
determined by the amount of work needing to be performed and when
it needs to be performed. Understanding this will determine the
supply side of the equation. Time to revisit our mission statement!
Is the maintenance business mission to provide resources when
needed or is it to accomplish the work when resources are available?
Each response yields a different set of requirements. Therefore,
how much and when are critical drivers.
Is there a seasonality to demand? Are there periodic shutdowns?
Are there slow periods or accessible periods for maintenance?
Can the existing work force be supplemented with contract labor?
The real cost
drivers can easily be determined once everyone agrees on the mission.
Is the maintenance business mission to provide resources when
needed or is it to accomplish the work when resources are available?
Strategies for Success
In a study conducted by E.I. DuPont de Nemours & Company,
a comparison of American maintenance business strategies to other
countries was made. The highlights:
- Japan and Europe use substantially more contractors than
the United States
- Japan spends less to maintain its investment and its productivity
is higher
- Japanese companies have less stores investment with higher
turnover than European or U.S. companies
A similar study conducted by General Motors Advanced Engineering
Group found the following:
- More than half of all maintenance performed by those surveyed
was reactive whereas the world class perception was that only
18% should be reactive
- Preventive maintenance activities account for one third of
the effort with world class at just under 50% of all activities
- Predictive maintenance averaged only 13% of maintenance activities
with world class at 35% of all activities
Should these findings be alarming? Perhaps. On the other hand,
whats right for one company may not be right for another.
There are some basics that can be applied and have proven to be
successful. These include:
- Pre-planning and scheduling of work
- Improving parts and material availability
- Implementing self directed dispatching based upon a meaningful
priority system
- Identifying and establishing a meaningful backlog comprised
of corrective, routine preventive and predictive work
- Identifying, managing and deploying spare parts and materials
These are just some of the proven strategies and techniques for
a successful maintenance business. It should be noted that emphasis
on any strategy or technique should be driven from the maintenance
mission and its objectives. The decision to utilize more or less
contractors should be a decision based upon the goals of the business
and customer requirements. Some environments lend themselves more
to contract services than others. There is no single answer and
no single strategy other than first deciding the purpose of the
business.
Effort is Noble
But ItsResults
That Count
All too often, the concept of maintenance management is thought
of as synonymous with computerized maintenance management systems;
that by implementing a computerized maintenance management system,
results will magically appear. Long before computer systems, there
were successful businesses because attention was paid to customers
and the implementation of effective business processes to provide
goods and/or services to those customers. To achieve success in
managing the maintenance business, identification, development
and implementation of core business processes is essential. CMMS
is only a tool to support the processes. No matter how big or
small the maintenance function, there is no substitute for basic
process implementation. Ask yourself, if you can not define the
basic processes, how can appropriate application software be selected?
After all, one of the basic covenants of effective maintenance
planning is determining the right tools for the job based upon
the work and tasks to be performed. For those who have implemented
a CMMS, which came first, the system or the process?
Managing the maintenance business presents the challenge of operating
most service type businesses. Striking the fine balance between
service and cost demands the best practices supported by the best
tools. The effort required
to implement a computerized system does not translate to results;
effort put forth in the implementation of the right processes
will yield results. In the final analysis, its results that
count.
Striking
the fine balance between service and cost demands the best practices
supported by the best tools.
