How To Use SigmaXL for Design of Experiments (DoE) [VIDEO]

Posted on16. Mar, 2010 by Monique.

Design of Experiments (DoE) – SigmaXL Demo

this video tutorial will show you how to use the statistical software package, SigmaXL, to design a 3-factor experiment for a catapult competition.  You may recall this exercise that is commonly used as a learning project in statistical quality control courses.  Our goal is to identify the process drivers that significantly impact the process output.  The Pareto charts generate will indicate the most significant factors and rank in order from most to least significant.  We want to find the best settings for our catapult that will consistently launch a ball a distance of 100 inches.  Watch VIDEO to see demonstration. . .

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.

RUN CHART: What is a Run Chart?

Posted on17. May, 2009 by Monique.

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.

FISHBONE DIAGRAM: How To Construct A Fishbone Diagram

Posted on15. Apr, 2009 by Monique.

A Fishbone Diagram

or cause and effect diagram is a tool used during brainstorming sessions of Lean Six Sigma projects. This tool will help you drill down to root causes of defects and identify possible failure modes. You will use this graphical tool in conjunction with the Five Whys method of questioning. This tutorial demonstrates how to use SigmaXL software to present your findings during future tollgate presentations. View video for more information on this technique.

TAKT TIME: How To Calculate Takt Time

Posted on03. Apr, 2009 by Monique.

Takt Time

is the maximum allowable cycle time required to meet customer demands.  This is a video that defines takt time and gives an example of how to calculate takt time.  Takt time is important to the development and evaluation of standard work.  For example, if your takt time is 5 minutes, the cycle time for each operator in your must be below 5 minutes to meet customer demand. 

In my other tutorials I show how you can use SigmaXL to perform your analysis.  Since SigmaXL was included with my Black Belt certification tuition, I want to show you that you can use the Lean Takt Time calculator to perform this calculation.  The calculator allows you to quickly compare your takt time to your cycle times listed in your standard work.  As you can see, takt time is used to evaluate your standard work and recognize opportunities for improvement or modification.

How to do Multiple Regression Analysis with SigmaXL

Posted on05. Jan, 2009 by Monique.

 Learn how to perform Multiple Regression analysis with SigmaXL. 

Why perform a Multiple Regression Analysis?

Y = f (x₁, x₂, x₃, . . .x_n)

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.

Generate multiple Pareto charts – It’s EASY with SigmaXL!

Posted on30. Dec, 2008 by Monique.

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.
