Interdepartmental describes someone or something that is involving or occurring between different departments in an organization. It belongs to bureaucratic and academic absurdities and works best in satire, office complaints, and writing about systems that sound puffed up or overmanaged. It still feels usable today, especially when you want a word with more character than the plainest alternative.
