Departmentalism refers to the tendency of individuals or groups within a larger organization to prioritize their own department's goals, rather than working collaboratively with other departments for the good of the organization as a whole. Synonyms for departmentalism may include silo mentality, turf wars, organizational fragmentation, and stovepiping. These terms all describe a similar issue of departments being insular and focused inwardly, rather than working towards shared goals and objectives. To combat departmentalism, organizations may implement cross-functional teams, encourage communication and cooperation between departments, and establish shared metrics for success. Ultimately, breaking down departmental barriers can lead to greater efficiency and success for the entire organization.
