Lean Manufacturing is a business improvement philosophy
that has developed over many years (as well as a collection of lean
manufacturing tools), it is a method to better focus your business on the true
needs of the customer to help you prevent waste from being built into your
system. When properly implemented, lean manufacturing provides many advantages,
which include improving flow (material, people, information, and work) and
eliminating waste.
Lean has been around since the late eighties/ early
nineties, but despite the enormous popularity of Lean, the track record for
successful implementation of the methodology is spotty at best. Companies still
make mistakes when implementing Lean.
These mistakes are generally due to simple
misunderstandings of the Lean principles, but when something goes wrong, you
will not reap the full benefits, and incorrect use of Lean can actually make a
situation worse rather than better.
In my experience there are 4 tips for implementing Lean with
success:
Create a Strategic Plan Instead of a Project
Plan
Lean must first start by deploying a crystal-clear vision
all the way down to the entire organization of the company. Companies must
determine ahead of time what the vision and direction will be. A proper
strategy must assign clear responsibilities and show what resources are to be
committed. All employees of the company must clearly understand the company
vision and direction and must also understand all KPIs (Key Performance
Indicators) and measurements used. Metrics and timelines must be defined.
Management must decide what core elements are to be deployed and the order of
deployment. They also must determine where to start and how Lean will expand
throughout the operation.
Focus on Culture Change
Lean is about people. All successful and sustainable
business change starts with top management (leadership team). Culture by design
requires changing the way that people think and work. That’s difficult to do,
because people get comfortable with the way they are. You must establish a
foundation so that change can happen. The definition of ‘win’ has to be shared
and understood by everyone.
A new lean culture will not develop unless the
organization’s leadership team is willing to model and be the examples of the
new behaviors.
Address Business Problems
Don’t blindly copy others. Some companies think
they will get desirable effects by applying Lean tools that others have gotten
great achievements. Tools do not solve problem but rather people do. It is not
about the tools it’s how they are applied. A large number of organizations have
failed to produce the desired results from the direct and prescriptive
application of Lean tools. The tools themselves have been proven to work in
many situations. The difference must then be in how the tools were applied, their
appropriateness, but not the tools themselves.
Successful implementation of any Lean tool must be closely
related to the management philosophy. So we can’t succeed by imitating and
copying practices of others indiscriminately, it must be combined with local
culture. It is important to continually reevaluate your lean
manufacturing efforts. Even when you take the long-term into consideration,
changes in your business plan, demand levels and industry trends can create
possibilities to further improve your factory.
Train Everyone
The key to implementing any new idea or concept is
training. It must be top down training so that everyone is on the same page.
The more understanding of what lean manufacturing is all about, why you are
implementing it and the expected benefits from it, the more likely you are to
get buy-in.
It is very important that everyone in the company become
committed to lean culture. In order to make the culture successful, managers
and employees need to be aware of waste within the company and be prepared to
attack and eliminate it. Making sure that the employees are empowered to do
this, not just pushing the job off on someone else, is imperative in the proper
function of lean culture.
Ensuring everyone is on the same page will help to avoid
conflict. At the same time, it is important to ensure people have the space in
which to think about what improvements they think need making.
Implementing a Lean manufacturing program is a continuous
process. The success of one stage builds up the momentum for the next one. Most
of the implementation challenges stem from human resistance and incomprehension
of advanced work tools. Companies can achieve accelerated success by instilling
a culture of change among employees, and can also leverage digital resources to
improve data collection, analysis and utilization.
