Do we need outside help to get Lean Manufacturing?
Once the decision to go Lean is made, companies often employ a Sensei, which is a Japanese
term for teacher. The best way to find a competent Sensei is to get a referral from a company
in your area that has successfully implemented Lean.
Some companies do not like to hire outside consultants or trainers, but prefer to train
their own staff or hire an experienced Lean Professional to hold the role of Sensei. Continental
offers both training and technical staffing to help companies in these endeavors.
After we understand Lean Manufacturing and have lined up some help to go Lean, what
is our next step?
To make such a major change in your operation, there must be a motivating factor such
as a threat of lost business or cost pressure. This motivating factor is called a crisis.
An example of a crisis would be a demand for a 3% price decrease from your customer that
would make you unprofitable. Another crisis would be threat of losing the business to a
A crisis motivates you and your staff to rethink the business and creates a situation
that demands change. Without a crisis, things normally run as they always have, and change
is looked upon as a bad thing. If there is no immediate crisis then you must "create"
How do I "create" a crisis?
There are many ways to do this. Example #1: Benchmark your competition. By doing this
you will surely find areas in which they perform better than you. Use Lean to leapfrog
your competition. Example #2: Identify a new customer that you would like to acquire, but
has higher demands than your current customers. A customer that is currently using Lean
Manufacturing principals would be a good target for this. Use this created crisis as the
impetus for the implementation of Lean in your plant.
Once we have identified or created a crisis, what is next?
Next, you need to map your Value Stream as defined previously. Some companies start
by Value Stream Mapping the entire plant. Others pick one manufacturing line and map that.
Whichever one you do, it is vital to not skip this step.
If you have mapped the whole plant you now need to pick what looks to be the most fruitful
area for change and get started. For example, if you made 6 different parts in your plant
and part #3 has extremely high scrap, then you know you would make a major impact by starting
there with Lean. The Value Stream Map will point you to the highest area of MUDA (waste),
which is the ideal area to begin Lean implementation.
To summarize the five-step process to becoming Lean, which are fully outlined and detailed
in the book Lean Thinking are:
- Find a Change Agent
- Find a Sensei
- Seize (or create) a crisis
- Map the entire Value System
- Pick something important and get started
Is There "Certification" Associated with Lean Manufacturing?
The Society of Automotive Engineers (SAE) has established SAE J4000 in which they will
train, test and certify individuals as first and second party assessors.
The purpose of J4000 survey is to establish an objective benchmark of one's current
state in pursuit of Lean Operations.
The content strategically isolates areas of business into (6) six categories:
- Planning & policy
It will identify strengths/weaknesses within the value stream of company operations,
as well as provide a positive tool for comparison & contrast between supplier and customer.
It will also help to open areas of communication, meanwhile establishing action items,
target dates and individual responsibilities. The ultimate goal is continuous improvement
involving all areas of business.
SAE J4000 is on its way to becoming to Lean Manufacturing what QS-9000 and ISO9000 has
become to quality.
To become certified as an assessor, one must attend a four day training session. Two
days are spent on management application track and two days on a operation application
track. After successfully completing the seminar and passing the required test, the individual
will be a certified assessor. Continental Design & Engineering provides certified assessors
for their clients.
