6 Sigma Statistical Process Control (SPC) Software for Windows
Using the theory that approximately
2700 parts per million, (PPM), parts/steps will fall outside the
normal variation of +/- 3 Sigma.
In spite of this,
when we build a products containing 1200 parts/steps, we can expect 3.24
defects per unit (1200 x .0027), on average. The result of this is a rolled
yield of less than 4%. That is equivalent to fewer than 4 units out
of every 100 will go through the complete manufacturing process without
any kind of a defect.
It can be shown that a +/- 6 sigma can be
expected to have no more than 3.4 parts per million defective
for each characteristic, even if the process mean were to shift by as
much as +/- 1.5 sigma. In the same case as above, a product containing
1200 parts/steps, we can now expect only only 0.0041 defects per unit
(1200 x 0.0000034). This would mean that 996 units out of 1000 would go
through the entire manufacturing process without a defect as the
distribution below shows.
Both our software
products are geared to this end. And at only $150.00 and $65.00, (USD),
our software can get you going quickly.
