6 Sigma Statistical Process Control (SPC) Software for Windows
There are many
examples of the results of implementing a six sigma objective, and
it seems to work even though there are criticisms of the system by
some. In order to use six sigma, you CANNOT just take any given part
of it and evaluate it. The entire system MUST be evaluated as a
whole system for it to work. Below are some of the documented
success of implementing six sigma.
Using all the steps
along with measurement techniques can and does improve process
performances and reduces cost.
Six Sigma Successes
There have been many Six Sigma success
Examples of Fort Wayne Indiana’s Six Sigma
trained black belt program:
- Water main costs were reduced from $61.00
per foot to $50.00 per foot.
- Numbers of days to get Improvement Location
Permits were reduced from 51 days to 12 days.
- 50% reduction for transportation engineering
projects change orders.
- Numbers of fire code re-inspections were
increased by 23% while reducing the number of days for re-inspection
from 51 to 34 days.
- Missed trash pick-ups reduced by 50%
- Response for pothole complaints reduced from

In Engineering and Construction, Bechtel, on
the Channel Tunnel Rail Link project in the UK, the project team
uncovered a way to save hundreds of job hours on one of the tunneling
In healthcare, North Carolina Baptist
Hospital says, "The Six Sigma process improvement deployment at
North Carolina Baptist Hospital is starting to show the kind of
results that convert skeptics to believers." and "A Six
Sigma process improvement team charged with getting heart attack
patients from the Emergency Department into the cardiac
catheterization lab for treatment faster slashed 41 minutes off the
hospital’s mean time" http://www1.wfubmc.edu/articles/Six+Sigma
Six Sigma-Based Methodology A Motorola/3M
According to the The Institute of Quality
- ‘Wipro reports successes in its first
year. "First of all, we now have a common language across our
divisions." … "Defects are steadily falling in cylinder
- "Although Motorola has made huge
reductions in defect rates, it has not yet achieved Six Sigma
overall. Motorola now considers itself a 5.7 sigma company. While
Six Sigma is a noble goal, the rate of improvement is what is
important. It has saved Motorola billions of dollars in costs (in
terms of scrap and re-work)"
- "Six sigma was appealing because it is
pretty straightforward," says James Bailey, executive vice
president and corporate quality officer for Citibank.
