Step 2: Problem cause

In step 2, you use visual representation of the Ishikawa diagram (fishbone model) with 5 factors involved ("FISHBONE" tab).
Alternatively, you can use the 5-Whys method ("FIVE WS" tab). The choice of method remains unchanged throughout the process.

The left column displays the answers from the question catalog.

3 elementary tools facilitate the display on the workspace:

Since it can happen that no problem solution is achieved in one pass, it is possible to work with different versions at this point.

You can work with 3 versions. You can hide and show the contents using the version switch.

FISHBONE tab

The main branches of the Ishikawa diagram have 5 possible categories of causes.

  • Environment

  • Methods

That way you can make sure that no influencing factors are forgotten.

Follow these steps:

  1. Click the icon

  7. If you want to close the dialog box without saving the cause, click "x".

Entering the child element of the cause

  1. Click the parent element of the cause and select "+" in the toolbar.

  2. Fill in the "Title" and "Description" field.

  3. Then continue with the next steps as in the parent element.

Deleting potential causes

Follow these steps:

  1. Click the cause and select the icon

    in the toolbar.

Example

For a problem with a water leak, the team has collected 7 potential causes.

FIVE WS tab

If you expect a single cause, you can use this simple method instead of the Ishikawa diagram.

You determine the root cause of an error or problem by repeating the "Why" question. Each answer forms the basis for the next question.

The number of questions is not limited to 5.

Solution action

You set tasks for your team based on all the collected causes.

The "NEXT" button takes you to step 3 of the wizard, the problem solution.
