This document discusses various techniques for analyzing work processes including motion study, time study, and establishing work instructions. It focuses on using micromotion film analysis and developing SIMO (simultaneous motion) charts to record and analyze worker motions. Therblig symbols are introduced to categorize different types of hand and body motions. Principles of motion economy are outlined related to uses of the human body, workplace arrangement, and equipment design with the goals of eliminating unnecessary motions and balancing the workload. Checklists are recommended to thoroughly analyze motions and ensure consideration of factors like safety, productivity, and regulations.
