(Proven Process to establish Reliability)

The
Three Waves to Reliability Excellence is
a proven methodology for effectively implementing a
global reliability improvement strategy in large
multinational manufacturing organizations. This process
is an integrated strategy that consists of proven
maintenance, reliability and manufacturing fundamentals
planned and implemented by the local organization to
provide the stability required to provide the stability
required to allow sound lean manufacturing processes to
succeed. It relies upon unwavering corporate
sponsorship and a well planned and executed
implementation strategy implemented by the local
organization guided by qualified subject matter experts
and coaches. The foundation of this methodology is a
cooperative partnership between operations and
maintenance. In this partnership, operations own
reliability and maintenance is an equal partner
dedicated to provide timely and effective methods,
skills, expertise and support. Charles Bailey, V.P.
Operations, Eastman Chemicals came to this conclusion in
his quest to achieve reliability:
“Reliability cannot be driven by the
maintenance organization. It must be driven by the
operating units… and led from the top.”
This proven methodology can be likened to
three very powerful waves that have been proven to
deliver unprecedented results. Do not attempt to
implement this process unless you are convinced that the
current system is broken and you are completely
committed to change the processes and systems you
currently employ. I think W. Edwards Deming was spot on
when he said:
“Your system is perfectly designed to
give you the results that you get.”
Wave 1
– The methodology starts with development of a high
level corporate or business unit financial business case
for reliability improvement based upon achieving
reasonable business and performance improvements and
conducting Reliability Excellence education for
all participants on the core reliability and
manufacturing concepts and implementation strategies.
The preliminary education consists of education and
workshops for combined groups of executive level
management, plant management and supervision, operators,
maintenance personnel, engineering, and other support
functions such as purchasing and finance. The workshops
conducted during this phase of the initiative will
result in identifying tactical improvement opportunities
and creating cross functional teams that immediately
engage in resolving these issues and capture short term
gains that can be utilized to provide the funding for
wave 2. This is the first step in creating awareness of
new methodologies and alternative solutions, the value
of creating cross functional teams focused on a single
issue and the collective discovery of the solution
begins the very important process of changing the
existing culture.
Wave 1 has is actually performed in two
parts:
The first part is the business case
creation and presentation to educate senior management
of the compelling reasons and benefits to improve
equipment reliability. The second part is the education
at the plant level that includes both plant management
and a mix of operators, maintenance personnel and
engineering. This education is followed by a workshop to
show how cross-functional teams consisting of operators
and maintenance personnel can address and solve
reliability issues.
The high-level business case must be
prepared and communicated to executive management to
gain sponsorship. Executive management must provide the
sponsorship and demonstrated commitment required to move
the initiative forward. This executive sponsorship,
and only this executive level sponsorship, will provide
the entire organization a compelling reason to change.
This is especially effective when the business case
stresses the competitive environment and external
threats to the business. The business case must be
supported by a reliability strategy that focuses the
entire organization on the reliability and technological
issues related to the business and communicating this
strategy throughout the organization. The second step
is to provide education on reliability principles
throughout the organization making it clear that
reliability, like safety, is everyone’s responsibility
and create the expectation everyone will participate in
the process. Consideration must be given to existing
initiatives that are currently underway, i.e., TPM, 5S,
RCM, Lean Manufacturing, etc., and make the connections
to these processes. It is critical that the reliability
improvement initiative not be perceived necessarily as a
stand-alone new initiative, but rather an enabler or
foundation to the current improvement processes.
“It is critical that the reliability
improvement initiative not be perceived as a new
business improvement endeavor. Use the Three Waves to
Reliability model to focus and fully realize the
potential of any existing Lean, TPM, or Six Sigma
improvement and change management infrastructure.”
The entire process must be defined and
communicated in Wave 1, making it clear that
management is committed, has clear expectations, and
intends to follow through. This will help dispel any
false perceptions that this initiative is a flavor of
the month or program of the day.
As a part of the education provided in
Wave 1, it is imperative that workshops are
conducted to identify obvious reliability issues and the
financial impact they have on the operation.
Cross-functional teams are then formed to resolve these
issues and measure the progress and savings. These
teams are tactical in nature and should not get involved
in systemic or organizational issues. The strategic or
systemic issues will be dealt with in Wave 2 and 3. The
purpose of the Wave 1 activities is to start the
change process and to set the stage for the cultural
change that must occur within the organization as we
move further into the process. To foster real action,
the leader of each tactical team must provide a written
statement to the plant manager or his immediate
supervisor outlining the issue the team will be
addressing and the expected outcome within a few days of
the conclusion of the workshop. Management must then
follow up on these initiatives. If this Wave of
the process is effectively carried out, the savings can
potentially finance Wave 2 and possibly Wave 3.
Wave 2
– The next step in the process is an assessment of
current conditions at a specific location, financial
analysis that results in an estimate of the value in
closing the gaps to Reliability Excellence
compared to the cost of implementation presented as a
return on investment (ROI) calculation and a preliminary
master plan that outlines the processes and
methodologies required to close the gaps. The gaps are
simply current conditions and existing processes and
practices compared to reasonable targets of best
practices within a specific industry or in general
industry. The assessment is a highly participative
process that provides a high level of awareness and
discovery that again contributes to the continuation of
the cultural change that must take place to set the
stage for Wave 3 or implementation.
Wave 2
begins with an overall assessment of the
operation, measuring current status of twenty-one
specific elements of reliability shown in Fig. 1 “The
Reliability Arch” with scores for each element and a
composite score that allows us to identify the gaps in
the current processes and structure. These scores also
give us a visual comparison with others either within
our industry or from industry as a whole. With this
information we can now develop a master plan
An outline of the actions that, when
completed, will close the gaps to excellent. The master
plan at the completion of Wave 2 is not a completely
detailed, but has enough detail to outline the elements
that will be addressed and are fully detailed in Wave 3.
We can now develop a Return on Investment
(ROI) by determining the financial impact that closing
the gaps identified in the assessment will have on the
operation compared to the cost of executing the plan.
In most cases the ROI is in excess of 10:1 and in a few
cases it has exceeded 30:1. Savings or cost avoidances
generally come from similar areas in most plants, i.e.,
loss of product due to: availability, rate and quality;
maintenance spending, overtime, inventory investment,
work in process, etc. Typically gains from operating
improvements range from 1.5 to 6 times more than gains
from maintenance.
Wave 3
– Implementation is the final step in the process. Wave
3 is the implementation of the master plan and includes
education/workshops on the proper techniques,
coaching/mentoring on the correct execution and
establishment of defined processes and effectiveness
measures of progress. Again there is a focus on
organizational change management through the use of a
leadership team and implementation teams and education
to ensure that all process and structural changes are
sustainable.
The organization will only succeed in the
implementation of meaningful change when management is
fully committed to creating the environment to allow
change to occur and dedicated to its successful
completion. Leadership is the key and the prerequisite
for sustained change.
Master Planning is the roadmap that keeps
us on course as we implement the identified processes,
systems and structures. Cross-functional participation
is a key ingredient to successful implementation of the
master plan. People tend to own what they create, so in
this wave implementation teams will fully detail and
implement the elements of the Master Plan. A
Leadership Team must be established to provide the
leadership structure for the overall change initiative
and to ensure compliance with company policies and
practices. Then create multiple Implementation Teams,
with dedicated leaders; to develop detailed action plans
for each specific element of the Master Plan.
This approach has proven to be an excellent vehicle to
foster participation and produce the desired results.
Coaches and subject matter experts must
be made available to the implementation teams at
appropriate times during the process to ensure that team
members have technical resources available for
consultation and effective technical transitions are
made. Much care should be taken in selecting Focus Team
leaders and members and ensure they have the proper
training and coaching to carry out their missions. A
Reliability Excellence Facilitator must be selected
from the organization and dedicated to this initiative
for the duration to ensure it’s success and keeps all
activities on track.
The Leadership Team should be no
more than three to five participants that represent a
good cross section of the local management team. These
Leadership Team members will define the mission of the
Implementation Teams, reconcile the investment and
return for the overall initiative and collectively have
the authority to make decisions to eliminate any
barriers identified during master planning and
implementation. To ensure appropriate Sponsorship an
Executive Sponsor should be identified to ensure
participation and input from executive management.
Implementation Teams
should also be a cross functional team
with no more than three to five participants each with a
dedicated leader that is responsible for all team
activities. Detailed action plans for each
element of the Master Plan will be developed and
reviewed at specified intervals throughout the
implementation phase with the Leadership Team.
When the action plans are agreed upon with the
Leadership Team and coordinated with all
Implementation Teams, the execution of the master
plan commences. Action plans will be identified, step
by step, resources assigned to appropriate personnel (to
include all plant personnel) and a completion time
established for each step.
The creation of a Support Team is
an effective way of providing resources to the
Implementation Teams on an as required basis, i.e.,
external consultants and coaches, vendors, accounting,
human relations, etc. These individuals are not full
time participants, but are identified and available,
when needed, for consultation and information to the
Leadership and Implementation Teams.
The number of implementation teams
depends upon the size of the local organization and will
heavily influence the duration of the change
initiative. The time requirements for Leadership and
Implementation Team participants during plan development
and implementation range from 10% to 15% for leadership
team members, 20% to 25% for implementation team
leaders, 15% to 20% for implementation team members and
100% for the Reliability Excellence Facilitator.
New Implementation Teams are commissioned
as existing ones complete their missions until all
elements of the master plan are fully implemented.
Some important thoughts to remember as
you get underway are there are always two parts to any
prescription:
1)
Prescribe
the right medicine
2)
Ensure it’s proper and complete use or
application
While the medicine has the potential to
cure, only it’s proper and complete use will make it
effective and produce the desired results. This is the
core issue with Flavor-of-the-Month or Program of the
Day improvement programs. Routinely the concepts are
sound, however the implementation method and complete
application is either premature, incomplete or
shortsighted.
In most manufacturing environments, two
rules hold true:
1.
Production
capacity of the plant and maintenance spending are the
most significant controllable parameters in the success
of the overall operation.
2.
Capacity is a function of equipment
reliability and sustainability.
Simply summarized: when equipment is
reliable, product is made. So how do we increase
reliability? TPM?, RCM?, Six Sigma?
Yes and no, these methods and processes
all have proven results, but ONLY WHEN PROPERLY AND
COMPLETELY APPLIED! These concepts are very powerful
when applied to a stable operation that has sustainable
equipment reliability can produce tremendous results,
but tend to fail miserably when applied in an operation
where the fundamental work processes are not established
or fully utilized and equipment reliability is not
established.
In the physical world, momentum,
equilibrium, and the force necessary to enact change
heavily influence our daily lives. When dealing with
organizations, teams and individuals momentum and the
force necessary to enact change are every bit as
challenging. Resistance to change is a very powerful
force and you are likely to hear these reactions when
attempting to implement a change initiative of this
magnitude:
·
“I/We are comfortable where we are, why
should we change?”
·
“We will do it your way for a little bit,
but go back to the old way as soon as we can”
·
“I’ve already got a full time job. This
is just more work.”
In The Three Waves to Reliability
Excellence process, prescribing the medicine and
ensuring it’s proper application are integrated. Just
as importantly, outsiders do not develop the
prescription; it is developed by the local organization
in a participative discovery process with all the
justification predetermined and communicated up and down
the organization. Again Deming had it right:
“A system cannot know it self, it must be
examined by outsiders, by invitation only”
The core foundation of The Three Waves
to Reliability Excellence is in establishing the
ownership of reliability. It is much like your
automobile. Who owns the reliability of it? Is it your
mechanic or dealer? No, ownership of its reliability
must be with the driver or operator. Operators live with
plant equipment day in and day out, much like the driver
of a car, and good operators have an inherent feel for
when their equipment performance begins to deteriorate
or is in jeopardy. If a sense of ownership is created in
operations for their equipment, the desire to fix it
before it breaks or avoid failure increases. If
maintenance is established as a true partner, then both
operations and maintenance will have an increased desire
to do what’s best for the equipment/line/plant and “Fix
it right or avoid the failure” will replace “Fix it
quick or hurry up and get it back on line”.
Sustaining these changes is again, a
matter of leadership and dedication. When proven work
processes are developed and in place, systems are in
place to automate these work processes, leadership and
dedication to always do it the same way is instilled and
rewards have been reaped, real change has occurred and
reliability will be evident and Reliability
Excellence will be the basis of the way you conduct
your business.
