Case Studies To consolidate these concepts, this section presents brief case studies illustrating collective performance in different contexts: Case Study 1: The Hawthorne Works (1920s USA, Industrial Organisation) Context: Western Electric’s Hawthorne Works factory, Chicago. Scenario: Researchers conducted experiments altering work conditions (lighting, break times) to see effects on productivity.
