Question

)if there are 8 parts in a product and they are each at 6 sigma with a 1.5 shift, determine the ppm for the product

Answer 1

Answer:

ppm value = 0.000027 parts per million

Step-by-step explanation:

Given:

number of parts(n) = 8

From table: percent conformance in six sigma = 0.9999966

Using the formula of ppm value in terms of percent conformance and number of parts:

$ppm\,value = ( 1 -( \frac{percent\,conformance}{100} )^n )$

Plugging in the values:

$ppm\,value = (1 - (\frac{0.9999966}{100} )^8 )$

$ppm\,value = ( 1- 0.999972)$

$ppm\,value = 0.000027\,parts\,per\,million$
