Negative and inappropriate personality traits, insufficient knowledge, awareness of the benefits of teamwork, lack of material resources and incentives were ineffective, and the inefficiency of interpersonal communication system, inappropriate organizational structure with teamwork, and inappropriate culture of teamwork were also accountable. Also, the inappropriate culture of teamwork is the key and most influential component, and the lack of up-to-date and practical training is the most effective component.
