Too much documentation: Many companies have too many documents that tend to hinder the function of QA/QC departments. Some major companies have excessive documentation that employees may become overwhelmed and possibly lose interest in the quality management system and therefore impede the expected outcome. A company that I worked for previously had so many work instructions pertaining to a given subject that some of the instructions contradicted each other.
Colleagues often think quality control belongs to the people that initiated/created it and therefore don’t actively contribute to improving the system.
