Six Sigma Basic Key Terms - Part IV (Implementing/ the core six sigma)

Implementation Partner: An outside expert engaged in introducing, training, and supporting your Six Sigma initiative.

Hard Dollars: Savings that are tangible – exact, quantifiable cost savings, such as reduced hours, reduced inventory levels, etc.

Soft Dollars: Savings that are intangible – expanses that you avoid, such as not increasing hours, inventory, or physical workspace.

Gauge repeatability and reproducibility study: A study to ensure that your measurement systems are statistically sound. The gauge R&R is a confidence meter of sorts! It measures how you are measuring, so you know that your systems are measuring accurately and appropriately.

Variable: A characteristics that may take on different values. There are two kinds, dependent and independent. Their roles are significant in terms of the effect they have in any process.

Dependent Variables: The factors that depend on other factors. 

Independent Variables: The input factors – the X’s – that determine the output factors or the outcomes as a result of their functions. Among these we identify the vital few factors that influence and determine almost every aspect of a process. In DMAIC, these are the elements we work to isolate and then control.
