How to perform Analysis

Step 1: Open Sigma Magic
  1. Click on the Sigma Magic button on the Excel toolbar.
  2. Click on the New button to create a new project.
Step 2: Add the analysis template
  1. Click on the Tool Wizard to add the analysis template.
  2. Click on Lean and then SMED Analysis.


Step 3: ​Specify analysis options
A new worksheet will be added to your workbook. Analysis Setup will be automatically opened, in the setup tab specify the following details.



Click on OK button to save changes and update your analysis results.A sample screenshot of the worksheet is shown below.





If you need to make changes to the charts, click on the Analysis Setup and then the Charts tab. You can specify the following details,

 Labels:

  • Add a title for the chart.
  • Label the X-axis and Y-axis appropriately.

Appearance:

  • Adjust colors, font sizes, or other visual elements as needed.
  • Enable/disable gridlines or background shading.


Finally, click on Verify tab to ensure all the inputs are okay and shown in a green checkmark.



Step 4: ​Generate analysis results
Click Create and then Compute Output to see the overall result.



Interpreting Results

Overall Performance
Actual SMED Time: 47 minutes
Target SMED Time: 22 minutes
Percentage Reduction: 53.2%
The team has been able to reduce the SMED time significantly, more than the target of 50%. This is a good sign and shows that lean implementation has been successful.

Stage-wise Analysis
The "SMED Time Split Up by Stage" graph gives the time spent in various stages of the SMED process.
Internal: 37 minutes
External: 10 minutes
Internal activities are those that can be done only while the machine is idle, while external activities may be done on the production side. The above analysis reveals that much of the time is still utilized by internal activities.

Time Saved and Efficiency Improved
10-20% of changeover time saved.
Better usage of resources with less downtime.
Reliability improved and consistency better.
Changeover time reduction enhances the on-time performance.
Aircraft utilization and efficiency in operations enhance.
Increased customer satisfaction and cost savings.
