1 | Analysis Type: Specify the format of the chart. This selection is not enabled since there is only one format available. | ||||||||||
2 | Num Whys: Specify how many Whys you plan to use for your analysis. The number of whys you specify here will impact how the worksheet is formatted. You can change this number later, but ensure you have sufficient whys. The default value is 5. | ||||||||||
3 | Display Elements:
You can customize your worksheet by displaying the elements you are interested in. By default, the 5Why worksheet always contains the problem statement row, the root cause row, and the response to the 5Why questions. However, depending on your situation, you may show more information on the worksheet. This will help you guide the discussions within your team to arrive at the correct root causes and countermeasures. Select the checkbox for the following items:

Num | Description |
---|---|
1 | Write a short one-line description of the problem statement for which you want to perform the 5Why analysis. Make sure that if there are several problems you are working on, each problem will have its 5Why analysis worksheets. |
2 | The root cause row contains the final root cause of this analysis. Leave this row blank, as the software will fill this row for you based on the response to the final 5Why question on your worksheet. The software will overwrite any information you enter on this row. |
3 | If you have selected to display the countermeasure row, once you have completed the 5Why analysis and determined the root cause, fill out the countermeasure row. The countermeasure could be a combination of both temporary and permanent countermeasures. |
4 | If you have selected to display the impact row, share the impact of addressing this root cause and the selected solution on the problem statement. For example, this countermeasure will resolve 70% of the problem (or will result in a benefit of $100K). |
5 | Continue asking why and fill out the above information for each why. Note that there may be more than one cause for a problem statement. Make sure the causes you enter are validated - in the sense that you should have verified by going to the Gemba that this cause has been observed. For each 5Why block, you need to fill out the following: |
6 | If you have selected to display the 5Why question, frame the right 5Why question and display the question here. You should display the 5Why question clearly so other participants can review your thinking and ensure you have done the right analysis. |
7 | Enter the response to the 5Why question in the next row. Ensure the response is factual and based on the evidence you have collected. Don't guess the probable response here. If there are multiple causes, specify the most important cause or create multiple worksheets for each cause. |
8 | If you have selected to display the 5Why evidence, share the evidence you collected to justify the response indicated in the earlier column. |
9 | Continue asking why until you have reached an actionable root cause within your team's control. |
