The primary corrective strategy we must embrace is that assigning blame whether intrinsic or extrinsic, is wasted time and energy. It is not possible to blame and improve at the same time. This is vital for people at all levels to embrace, but particularly in management/leadership. A just culture where people feel empowered to come forward with errors is vital to safe and secure operations. Errors are going to occur, and it is our knowledge of them that allows system and process modification to prevent similar errors moving forward. Think of it like this, if you are a parent meeting your child's first "boyfriend or girlfriend", it is your response that often dictates whether you meet the next one or not.
