LENGTH: One Hour
Root cause analysis is typically performed because a process or a piece of equipment is not performing as desired. That is, there is a variance between what is expected and what is found. Finding the causes of that variance then involves trying to find what factors (among the many inputs and controls) are also varying from what is necessary to produce the desired output.
There are many different graphical tools for performing this variance analysis. Some are for measured data, some for count data, and still others for general information. Which tool is best is also dependent on the sample size and number of variables to be analyzed.
This one-hour webinar will demonstrate the use of several of these tools, including histograms, dot plots, multi-vari graphs, Pareto analysis, pivot tables, and Is/Is-not tables. The demonstration will include proper interpretation of when the factors being analyzed are and are not the likely cause.
- The concept of variance analysis
- Variance analysis for variable data
- Variance analysis for attribute data
- Variance analysis for non-numeric information
- Cautions about significance
