The use of informal mechanisms may lead to defects being found but later forgotten, resulting in defects not getting removed or in extra effort in finding the defect again. In such a scenario, defect reporting and closing cannot be done informally. Often the person who fixes a defect is different than the person who finds or reports the defect.
