An important distinction regarding success the distinction between conscious and unconscious success in unconscious success we create an achievement or least experience and achievement and do zero reflection on what exactly we did to help bring it about. Included in this zero reflection is the practice of superstitious explanations, credit and blame.
Conscious success occurs when we actually determine using data the real causes of our achievements. This often entails testing and retesting our hypotheses about the conditions of our success through future experiments and experiences. We know we have achieved conscious success when we can intentionally replicate an achievement. Until we arrive at conscious success we manage largely by hope and optimism.
To a large degree when slow teams get stuck in their performance it can have less to do with how often and how they fail or even why they fail in more to do with their lack of creating conscious success from their achievements.
