8. Job Shops Low Volume – High Variety of Goods & Services Processes may change from job to job. Highly flexible workforce and equipment. Manufacturing Examples: Tool & Die Shop, Custom Car Painting Service Examples: Beauty Solon, Hospital, Veterinarians Office (Many animals, many issues)
9. Batch Processes Medium Volume having job shop flexibility using repetitive techniques. Easy to set-up processes. Process runs batches using repetitive techniques. Flexible Automation Manufacturing Examples: Small Bakery, PIP style printing Service Examples: TV Show Production, Airline baggage handling
10. Repetitive / Assembly Line High Volume – Low Variety of Goods & Services Processes are very constant with little change. Lower skilled workers needed – Fixed Automation Manufacturing Examples: Auto Assembly, High Volume Electronics Service Examples – Cafeteria Lines, Ticket Takers
11. Continuous Processes Very High Volume – Very Low Variety Continuous Processes Frequently totally automated Fixed (hard) automation Manufacturing Examples: Making Steel, Fiberglass, Petrochemicals, Generating Electricity. Service Examples: Internet, Air Quality Monitoring, Delivering Electricity

13. Fixed vs. Programmable Automation Fixed Automation – designed to do a specific task. Specialized equipment – high volume at low cost, inflexible. Programmable Automation – may be reprogrammed to do many different tasks. General purpose equipment – lower volume/ higher variety, very flexible.
