What does departmentalism mean?
Departmentalism refers to an excessive devotion to the interests, procedures, and autonomy of one's own department within an organization, typically at the expense of broader cooperation and shared goals. The term is most often used critically — in discussions of bureaucracies, corporations, universities, and governments — to describe a 'silo mentality' in which units hoard information, guard budgets jealously, and resist coordination with counterparts elsewhere. In political contexts, departmentalism can also describe the structural arrangement by which governmental functions are divided among distinct ministries or agencies, though this neutral sense is less common today. Derived from 'department', which traces back through French to the Late Latin 'departire' ('to divide'), the word literally embodies division. Because modern management thinking prizes cross-functional collaboration, departmentalism is frequently invoked as a problem to be overcome — through reorganization, shared incentives, or better internal communication — making it a useful term for anyone analyzing why large institutions so often struggle to act cohesively.
Excessive adherence to the interests or procedures of one's own department within an organization, often obstructing cooperation with other departments.
"The report identified departmentalism as the chief obstacle to effective emergency planning."

The principle or practice of organizing government or administration into separate, functionally distinct departments.
"Nineteenth-century reforms entrenched departmentalism across the civil service."
Less common; found mainly in historical or academic discussion.
The word 'department' comes from Latin ' partire', to divide — and departmentalism is what happens when the dividing lines become walls.

Etymology of departmentalism
Departmentalism is formed from 'departmental' plus the suffix '-ism', denoting a practice, principle, or tendency. 'Department' entered English via French 'département' from Late Latin 'departire', meaning 'to divide into parts', ultimately rooted in Latin 'pars' (part). The compound arose in the nineteenth century as large bureaucratic organizations proliferated, particularly in British administrative and political commentary describing rivalries between government departments. Its cognates include other '-ism' formations built on Latinate roots of division, such as 'partisan' and 'partition'.
