### Go Deeper: Instructions for Use

Input areas are shaded in yellow and represent the following:

- Opportunities = the number of defects possible per unit
- Defects = # of defects
- Units = # of units in a sample

When you input these three items, the template performs the calculations and displays these metrics in cells B5:11

**DPMO:**defects per million opportunities**% defects:**percent of total opportunities that were defective**% yield:**percent that is not defective (1-% defects)**Sigma:**sigma level associated the the calculated DPMO (see reference table in columns D1:E9)**Zst:**Z short term**Zlt:**Z long term**DPMU:**defects per million units**Cp:**process capability metric = Sigma/3

#### Further definitions:

Defects and units are fairly straightforward but some folks struggle with the number of opportunities. The number of opportunities is based on how you choose to count defects. Here are some examples:

- One opportunity: an item is either wrong or right, good or bad.
- Two opportunities: A package could have the wrong product or the wrong # products in it.
- Example of three opportunities: a shirt you order could be the wrong: size, style or color.
