You can create an action from scratch yourself.
To do this, you can access the Create an action button on the Coaching Actions tab.

By clicking on it, you open a window inviting you to fill in different information:

Once you are done, press the Create button. You will then find it in your current actions from the "Actions" tab. Each time a step is validated, you can then check the box to mark it as completed.
Once you have checked all the steps, you can then Close the action and evaluate if you have indeed reached your goal and see the impact of your action on the next Pulse surveys (see "See the impact of actions").
