Consistency in behavior is important to your credibility. It lets others know that they can count on you to be consistent in your actions so they know what to expect from you.
In the ideal scenario, your Self ratings would be very consistent with your Observer ratings. But in the real world, scores are not always consistent.
There are a number of valid explanations for inconsistency in your feedback. For instance, some people know you better, people in various roles (or varying functions) have differing expectations of you, and you may behave differently with some people than with others. What’s important is to understand why people rate you differently than you rate yourself and think about the extent to which you need to be consistent.
