8. Copyright 2006 John Wiley & Sons, Inc.8-8 General Guidelines for Motion Study  Efficient Use Of Human Body  Work  simplified, rhythmic and symmetric  Hand/arm motions  coordinated and simultaneous  Employ full extent of physical capabilities  Conserve energy  use machines, minimize distances, use momentum  Tasks  simple, minimal eye contact and muscular effort, no unnecessary motions, delays or idleness

9. Copyright 2006 John Wiley & Sons, Inc.8-9 General Guidelines For Motion Study  Efficient Arrangement of Workplace  Tools, material, equipment - designated, easily accessible location  Comfortable and healthy seating and work area  Efficient Use of Equipment  Equipment and mechanized tools enhance worker abilities  Use foot-operated equipment to relieve hand/arm stress  Construct and arrange equipment to fit worker use

10. What is Job Design? Defined  Job design is the function of specifying the work activities of an individual or group in an organizational setting.  The objective of job design is to develop jobs that meet the requirements of the organization and its technology and that satisfy the jobholder’s personal and individual requirements.

11. Trends in Job Design  Quality control as part of the worker's job.  Cross-training workers to perform multiskilled jobs.  Employee involvement and team approaches to designing and organizing work.  "Informating" ordinary workers through telecommunication networks and computers.

12. Trends in Job Design (Continued)  Extensive use of temporary workers.  Automation of heavy manual work.  Organizational commitment to providing meaningful and rewarding jobs for all employees.

14. Copyright 2006 John Wiley & Sons, Inc. Underlying Principles of Learning Curves 1. Each time you perform a task it takes less time than the last time you performed the same task. 2. The extent of task time decreases over time. 3. The reduction in time will follow a predictable pattern.
