A Black Belt Project has been rumored to possess a requirement of a $300,000+ savings.


We do have a requirement of having a measurable effect on value. That effect has got to be initially determined during a well-developed Six Sigma Charter.

What are the Attributes of an honest Six Sigma Black Belt Project?

A good Six Sigma project features a solution that has got to be discovered through the method of study .
For example, if something is good/bad, can we know exactly what separates the great from the bad? Is this a subjective measurement that could be interpreted differently by different operators?

We should have measurable and controllable inputs (X’s).

For a Black Belt project, these measurable and controllable inputs (X’s) should be both Attribute/Discrete data and Variable/Continuous data.
For example, a process to fill a bottle full of a liquid could have the following “X’s”: Fill Date (Discrete), Fill Time (Discrete), Fill Operator (Discrete), Fill Height (Variable), Fill Weight (oz.) (Variable), Fill Liquid Pressure (Variable), etc. These measurable Inputs (X’s) combine to supply an Output (Y) with some measure of excellent or bad. The “Y” could even be a measure of Capability using CpK/PpK.
This Past data should be collected to populate a Multi-Vari sheet. For example, a Multi Vari Sheet might be an Excel spreadsheet where each row features a measurement for every of the “X’s” and every “Y” (if quite one “Y”).
In our “Bottle Filling” scenario, whenever a bottle is filled, there should be a measurement for every “X” that makes the “Y”. If we take a sample of 100 bottles, we should have 100 rows of data. This data helps us to do hypothesis testing as well as other statistical analysis to understand the true nature of the process.

In a Black Belt project, once discovering the Key Process Input Variables (KPIV’s), we’d find that we don’t know what specifications to optimize the KPIV’s.

For example, if we discover that Fill Liquid Pressure may be a KPOV but we don’t know the optimum pressure tolerance (Upper Spec Limit, Target and Lower Spec Limit) to get an optimum product (Output “Y”) then we will use a Design of Experiments (D.O.E.) to seek out the optimum pressure tolerance.
A Black Belt should be taught to know the planning of Experiment (D.O.E.) toolset.

This toolset will assist you to statistically get a far better understanding of what those specifications should be for the KPIV’s in question so as to urge a more optimum output.
There will be some difference during a Good Six Sigma Black Belt project between Service and Industrial disciplines.

In a Service discipline, generally , you’ll have more Attribute/Discrete “X’s” (Because most in commission disciplines will tell you that “we don’t make widgets with measurable tolerances”). Because of this, D.O.E. is less prevalent in a Service discipline.
