Organizational behavior is the study and application of how people act individually and in groups within organizations. There are four forces - people, environment, structure, and technology - and four models - supportive, collegial, custodial, and autocratic - that affect organizational behavior. Organizational climate is influenced by whether the organization is healthy or unhealthy according to characteristics like those in McGregor's Theory X and Theory Y and Ouchi's Theory Z. The document concludes with an activity where teams study case studies.
