I
believe when Lean principles are properly understood and applied, the upside
for productivity improvements is nearly infinite. I have personally witnessed
numerous Lean thinking initiatives that have improved productivity by large
amounts (like 40-60%) in short periods of time with minimal expenditures. The Lean track record is well documented by
numerous authors.
Despite
the enormous popularity of Lean, the track record for successful implementation
of the methodology is spotty at best. Some recent studies say that failure
rates for Lean programs range between 50 percent and 95 percent. The basic
reason why the implementation of Lean fails at most companies boils down to the
culture.
In
my experience these are ten reasons why Lean implementation fails:
- No Strategy
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. 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. Finally, the strategy should
anticipate problem and recovery scenarios. This is critical. Companies can fail
by attempting too much. They also can fail by attempting too little and
assigning the initiative to a "backburner" status.
- No Leadership Involvement
Lean requires top-to-bottom leadership of a
special kind. Lean leaders are firm and inspiring, relentless and resilient,
demanding and forgiving, focused and flexible. Above all, they have to be smart
and highly respected in the organization. Every successful company has at least
one of these leaders. These people must be a passionate part of the Lean
leadership team.
- Relying on Lean Sensei/Champion
Expertise obviously is necessary. So is
critical mass. There must be a sufficient amount of knowledge among a
sufficient number of people for lean to work initially and spread. Further, the
expertise must reside with line people as well as staff. Everyday support must
come from important, respected line managers who have the most to gain or lose
and have the power and authority to make things happen. Reliance on an
outnumbered staff expert who has no line authority to implement lean simply is
not realistic. Deployment and implementation can fail before it starts without
a strong implementation team
- Copying Others
Some enterprises think they will get
desirable effects by applying Lean tools that others have gotten great
achievements. 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.
- Thinking Lean Is A Tool
Lean implementation can not be treated as a
delegated "project." Lean manufacturing is not a project. It is a
fundamental change in the value delivery system. Top management must be in
front of this.
- Lack of Customer Focus
Many companies do Lean for internal cost
reasons rather than external and customer-focused reasons. The focus of Lean is
on providing the customer with more value sooner. Without customer focus, Lean
management techniques are difficult to employ.
- Not Engaging Employees
Employee participation in project decision
making is a main principle affecting innovation, productivity, and work
satisfaction. Workers
typically have more complete knowledge of their work than does management; hence,
if workers participate in decision making, decisions will be made with better
pools of information.
- Not Educating Employees
Lean training is crucial, obviously. But the
content, level, and depth vary by the company and its needs, activity, and
function. It goes back to the business case. Training needs to be appropriate
for the Lean elements to be deployed.
- Lack of Understanding
Most management teams don’t understand Lean.
When we don’t understand something it is next to impossible to support it. This
lack of understanding of Lean by management allows even the most subtle of
things to derail Lean efforts.
- Conflicting Metrics
Lean requires metrics that focus on the
processes of value creation and their associated costs. Traditional cost
accounting techniques such as absorption, as well as individual machine and
employee performance, can cause a lot of non-Lean behavior. Lean accounting
ties directly to financial measures but focuses on performance of the entire
value delivery system.
Lean
implementation is not simple or easy. However, results show that, when done
properly, Lean lives up to its promises. Lean and its elements work. All of the
failure modes presented here can be avoided or overcome.
nice article. actually every employee of an organization should perform as leader. consider the organization as family and I work for development of family.
ReplyDeleteGreat insight. In summary, management doesn't believe in putting in the effort to get the results.
