What does selfish departmentalism mean? !

What is selfish departmentalism? Selfish departmentalism is an idea or behavior that considers only one's own small unit without considering the overall interests. Selfish departmentalists lack the overall situation and overall awareness, and often focus on small groups when considering problems. Regardless of the pros and cons, they stand in a partial position, ignoring the overall interests in order to safeguard the interests of a few people, and even sacrificing the collective interests in exchange for the private interests of some people.
