This document discusses different types of organizational structures, including pre-bureaucratic, bureaucratic, post-bureaucratic, functional, divisional, and matrix structures. Pre-bureaucratic structures lack standardization and are common in small organizations. Bureaucratic structures have more standardization and are better suited for larger organizations. Functional structures group employees by specialized tasks while divisional structures group functions into divisions based on factors like geography or products. Matrix structures combine functional and divisional forms by grouping employees by both function and product/division.
