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
