Processes have many inputs
Inputs influence the output in different ways
To improve a process, we need to understand the relationship between inputs and the output
Improving key inputs has the greatest impact on our outputSix Sigma Basics
Y = f(x)
What’s the problem?
How does the process work today?
Can I trust my data?
What are the potential Key Process Input Variables (KPIVs)?
How do we know we have found the most important input variables?

Our Six Sigma Experience
Let’s consider an example
Each activity or task in a process is identified as:
Goal = Eliminate or reduce the waste!
A critical mistake is assuming we know what the customer wants!
Bursts become opportunities
Quality at Source
Every activity is structured
Every customer-supplier is clearly connected
Every flow path is simple and specific
We improve through experimentation
Get rid of old, traditional concepts and assumptions
Accept no excuses - Look for ways to make things happen
Say “No” to status quo and assume new methods will work
Don’t expect or worry about perfection, but look to continuously improve – starting now
The primary cost of Lean events is effort – not capital
If something is wrong, fix it on the spot
Empower everyone to think of ways to solve problems. Good ideas come when the going gets tough.
Before making decisions, ask “Why” five times to get to the root cause
Look for wisdom from 10 people rather than one
Improvement has no limits. Never stop trying to improve.
