The process is based on 5 stages that you need to work through carefully picking up the right statistical tools as you go.
The 5 stages are: Define > Measure > Analyse, Improve and Control
- Off-Target variation occurs when the process average is not equal to its target value.
- Common-Cause variation is the variation exhibited by the process while operating in its best manner.
- Special-Cause variation results from the intervention of causes that are unplanned and undesirable.
Structural variation is variation inherent in the system but appears to be due to special causes on a control chart. However, the causes of Structural variation are predictable.
The 7 tools are:
- Cause & Effect Diagram, also known as a fishbone diagram
- Pareto Charts
- Control Charts
- Scatter Diagrams
- Flow Charts
You have probably heard of them, perhaps even used a few of them, we want to help you use them all and see how they work together to effectively solve problems and control processes.
