Main calculations regarding The Voice of the Process in SixSigma: Yield, FTY, RTY, DPMO
Description
Computes the Yield, First Time Yield, Rolled Throughput Yield and Defects per Million Opportunities of a process.
Usage
ss.ca.yield(defects = 0, rework = 0, opportunities = 1)
Arguments
defects |
A vector with the number of defects in each product/batch, ... |
rework |
A vector with the number of items/parts reworked |
opportunities |
A numeric value with the size or length of the product/batch |
Details
The arguments defects and rework must have the same length.
Value
Yield |
Number of good stuff / Total items |
FTY |
(Total - scrap - rework) / Total |
RTY |
prod(FTY) |
DPMO |
Defects per Million Opportunities |
