3The Johnson Johnson Credo 3
- In 1943, General Robert Wood Johnson wrote and
published the Johnson Johnson Credo, a one-page
document outlining Johnson and Johnsons
corporate responsibilities in detail. Johnson saw
to it that the Credo was embraced by his company,
and he urged his management to apply it as part
of their everyday business philosophy. - Customers
- Employees
- Communities
- Stockholders
- Johnson believed that by putting the customer
first the business would be well served, and it
was.
4The JJ Credo 4
- Our Credo
- We believe our first responsibility is to the
doctors, nurses and patients,to mothers and
fathers and all others who use our products and
services.In meeting their needs everything we do
must be of high quality.We must constantly
strive to reduce our costsin order to maintain
reasonable prices.Customers' orders must be
serviced promptly and accurately.Our suppliers
and distributors must have an opportunityto make
a fair profit. - We are responsible to our employees,the men and
women who work with us throughout the
world.Everyone must be considered as an
individual.We must respect their dignity and
recognize their merit.They must have a sense of
security in their jobs.Compensation must be fair
and adequate,and working conditions clean,
orderly and safe.We must be mindful of ways to
help our employees fulfilltheir family
responsibilities.Employees must feel free to
make suggestions and complaints.There must be
equal opportunity for employment, developmentand
advancement for those qualified.We must provide
competent management,and their actions must be
just and ethical. - We are responsible to the communities in which we
live and workand to the world community as
well.We must be good citizens support good
works and charitiesand bear our fair share of
taxes.We must encourage civic improvements and
better health and education.We must maintain in
good orderthe property we are privileged to
use,protecting the environment and natural
resources. - Our final responsibility is to our
stockholders.Business must make a sound
profit.We must experiment with new
ideas.Research must be carried on, innovative
programs developedand mistakes paid for.New
equipment must be purchased, new facilities
providedand new products launched.Reserves must
be created to provide for adverse times.When we
operate according to these principles,the
stockholders should realize a fair return.
5The JJ Credo 5
- From the JJ Credo
- We are responsible to the communities in which
we live and workand to the world community as
well. - We must maintain in good orderthe property we
are privileged to use,protecting the environment
and natural resources.
6 Business Case 6
- DePuy Warsaws waste water contains copper levels
that exceeds permitted levels resulting in - Non-compliance to city permit
- (0.300 ppm max. daily, 0.150 ppm avg. monthly)
-
- (300 ug/L max. daily, 150 ug/L avg.
monthly) - JJ Guidelines mandate permit compliance
- Potential Fines
- Threat to the endangered Club Shell Mussel, which
thrives in the Tippecanoe River.

8Benefits of Project 8
- Financial Benefits
- Project supports 1.95M Cost Avoidance
- Project Supports DePuy meeting our Wastewater
Permit limits and avoid daily violations of 500
to 10,000 per day. - Community Outreach
- Project meets community Outreach Program to help
save the endangered Club Shell Mussel - Most Important Benefit
- Resolve the Needle in the Haystack problem
identifying the root cause of the high copper
levels, and implement permanent solutions to
solve the problem.

9How Do We Attack This Problem? 9
- Six Sigma was developed by Motorola in the
1980s, and consists of a set of statistical
methods for systemically analyzing processes to
reduce process variation. - Reducing variation is a key step to reducing
scrap and rework. - This presentation will focus on Six Sigma

14More Historic Data 14
Historical data says that the copper level in
incoming water was measured at 3 locations on two
separate occasions Location 1, Test 1 0.030
mg/L Location 1, Test 2 0.013 mg/L Location 2,
Test 1 0.120 mg/L Location 2, Test 2 0.132
mg/L Location 3, Test 1 0.100 mg/L Location 3,
Test 2 0.104 mg/L

15Thought Map 1 Questions 15
Thought map 1 led us through a series of
questions, and we ended up with the most basic
question of all Question Do we have a
measurement system that is adequate for measuring
copper levels to the finite level that we
require? Answer Perform a Gage RR/COV
Analysis.

Our study tells us that our gage system is more
than adequate to measure copper levels in the
incoming and waste water. It also tells us that
we do not have a high level of copper in the
incoming water.

20Test Plan Developed 20
- Develop plan to test waste water.
- Write CAR and install three new effluent sampling
stations - Lease and install seven dedicated sampling
stations - Begin sampling on the morning of November 24,
2005.

The composite results on day 34 and 35 are
alarming Even if the daily limit is raised from
150 to 300 ug/L, we will experience
non-compliance.

31What Have We Learned? 31
- We are close to our 300 ug/L limit many days.
- We are significantly over our limit on some days.
- What are we going to do to solve this problem?

RO Water System
Incoming city water travels 550 feet through 4
supply pipe in 4.8 minutes to reach the RO water
system.During this travel, the copper (Cu)
level increases from 10 ug/L to 200 ug/L.
ACTION ITEM 1 - Replace this copper supply
pipe with CPVC Plastic Pipe!

38Innovative Improvement Plan 38
- REPLACE SPECIFIC COPPER PIPES
- City of Warsaw verbally approved our plan and
agreed to the December 31, 2006 completion date. - Capital Appropriations Request was submitted and
APPROVED to replace specific copper pipes that
feed the RO System and Prototype Areas - Purchase a sampler and monitor our primary
wastewater outfall - Permit was re-written to 300 ug/L limit
- Follow up with DePuy Environmental and the City
of Warsaw to ensure that we remain within
compliance.
