FMEA: How To Perform a Failure Mode and Effects Analysis Tutorial

Posted on04. Jun, 2009 by Monique.

FMEA

stands for Failure Mode and Effects Analysis. This DMAIC tool is used to evaluate risk in a process. FMEA will help to improve the quality and safety of work tasks. Using this SigmaXL template will allow you to document a baseline for improvement and provide compelling data to confirm a need for changes to the current process. Detection level is critical to quantify the cost of poor quality. You would never want to pass on a defect to a customer or create an environment that puts employees at a risk of injury. FMEA encourages a proactive approach when used to assess risk in newly designed products or processes. This tutorial demonstrates how to use SigmaXL software to record before and after risk levels. View video for more information on this technique.

A Run Chart

is a time-ordered series data plot used to observe the performance of a process. Run charts are often shown on daily visual management boards to track key performance indicators. Recording daily trends can help identify abnormalities or variations in your process. You will want to record data in a run chart prior to establishing control limits in later phases of DMAIC project cycle. This tutorial demonstrates how to use SigmaXL software to test for randomness in a data set. View video for more information on this technique.

 Learn how to perform Multiple Regression analysis with SigmaXL. 

Why perform a Multiple Regression Analysis?

Y = f (x1, x2, x3, . . .xn)

 

To detemine which input or process variables (Xs) affect your output (Y).  Multiple regression helps find the source of  most of your variation in the process.  If you know the primary sources of variation you can reduce or eliminate the variation.  The demo below shows that Responsiveness to Calls and Ease of Communication account for 90% of the variation.  This tells you that your improvement efforts should center around these factors to have the greatest impact on Overall Satisfaction.

Why use the Advanced Pareto chart function?

To help prioritize your efforts to reduce/eliminate defects. The Pareto principle indicates that approximately 80% of process defects are caused by 20% of the problems. Separate the vital few from the useful many.   The SigmaXL function helps draw comparisons between similiar categories.
