Book is to chapter as organization is to department. It is a division of a larger organization into parts with specific responsibility. These divisions have its own specific function that would contribute to the whole organization. Hope this answers the question.

I believe the answer is : Departments

In a book, chapters exist to separate each parts of the writing that help the readers distinguish one important event with another. In organizations, departments exist to separate each important function that are necessary for the whole operation to run smoothly.
