Unless you already know that you need to self-assess yourself only in one given competence area, doing it for all seven areas can really take a lot of time. In fact, we do not recommend you to do so in one go. Instead, take your time. Think. Remember situations, and go gradually, competence area per competence area, competence per competence. You can save the excel file with your self-assessment on your computer, so nothing will be lost.
