organizational culture
The values and behaviors that contribute to the unique social and psychological environment of an organization.
Organizational culture includes an organization's expectations, experiences, philosophy, and values that hold it together, and is expressed in its self-image, inner workings, interactions with the outside world, and future expectations. It is based on shared attitudes, beliefs, customs, and written and unwritten rules that have been developed over time and are considered valid. Also called corporate culture, it's shown in
(1) the ways the organization conducts its business, treats its employees, customers, and the wider community,
(2) the extent to which freedom is allowed in decision making, developing new ideas, and personal expression,
(3) how power and information flow through its hierarchy, and
(4) how committed employees are towards collective objectives.
organizational structure
The typically hierarchical arrangement of lines of authority, communications, rights and duties of an organization. Organizational structure determines how the roles, power and responsibilities are assigned, controlled, and coordinated, and how information flows between the different levels of management.
A structure depends on the organization's objectives and strategy. In a centralized structure, the top layer of management has most of the decision making power and has tight control over departments and divisions.
In a decentralized structure, the decision making power is distributed and the departments and divisions may have different degrees of independence. A company such as Proctor & Gamble that sells multiple products may organize their structure so that groups are divided according to each product and depending on geographical area as well.
