1 Operations Management
Chapter 7 – Process Strategy PowerPoint presentation to accompany Heizer/Render Principles of Operations Management, 7e Operations Management, 9e

2 Mass Customization The rapid, low-cost production of goods and service to satisfy increasingly unique customer desires Combines the flexibility of a process focus with the efficiency of a product focus

3 Changing Processes Difficult and expensive May mean starting over
Process strategy determines transformation strategy for an extended period Important to get it right

4 Process Analysis and Design
Flow Diagrams - Shows the movement of materials Time-Function Mapping - Shows flows and time frame Value-Stream Mapping - Shows flows and time and value added beyond the immediate organization Process Charts - Uses symbols to show key activities Service Blueprinting - focuses on customer/provider interaction

5 “Baseline” Time-Function Map
Customer Sales Production control Plant A Warehouse Plant B Transport Order product Process order Wait Move Receive product Print Wait Move Wait Extrude Wait 12 days 13 days 1 day 4 days 10 days 0 day 52 days Figure 7.7

6 “Target” Time-Function Map
Customer Sales Production control Plant Warehouse Transport Order product Process order Wait Move Receive product Extrude Wait Print 1 day 2 days 6 days Figure 7.7

7 Value-Stream Mapping Figure 7.8

8 Process Chart Figure 7.9

9 Service Blueprint Focuses on the customer and provider interaction
Defines three levels of interaction Each level has different management issues Identifies potential failure points

10 Service Blueprint Figure 7.10 Personal Greeting Service Diagnosis
Perform Service Friendly Close Level #1 Customer arrives for service Warm greeting and obtain service request F Notify customer the car is ready Customer departs Customer pays bill F No Notify customer and recommend an alternative provider Standard request Determine specifics No Can service be done and does customer approve? F Level #2 Direct customer to waiting room F Perform required work Prepare invoice Yes F Level #3 Figure 7.10

12 Process Analysis Tools
Flowcharts provide a view of the big picture Time-function mapping adds rigor and a time element Value-stream analysis extends to customers and suppliers Process charts show detail Service blueprint focuses on customer interaction

13 Equipment and Technology
Often complex decisions Possible competitive advantage Flexibility Stable processes May allow enlarging the scope of the processes

14 Production Technology
Machine technology Automatic identification systems (AISs) Process control Vision system Robot Automated storage and retrieval systems (ASRSs) Automated guided vehicles (AGVs) Flexible manufacturing systems (FMSs) Computer-integrated manufacturing (CIM)

15 Machine Technology Increased precision Increased productivity
Increased flexibility Improved environmental impact Reduced changeover time Decreased size Reduced power requirements

16 Automatic Identification Systems (AISs)
Improved data acquisition Reduced data entry errors Increased speed Increased scope of process automation Example – Bar codes and RFID

17 Process Control Increased process stability
Increased process precision Real-time provision of information for process evaluation Data available in many forms

18 Process Control Software

19 Vision Systems Particular aid to inspection Consistently accurate
Never bored Modest cost Superior to individuals performing the same tasks

20 Robots Perform monotonous or dangerous tasks
Perform tasks requiring significant strength or endurance Generally enhanced consistency and accuracy

21 Automated Storage and Retrieval Systems (ASRSs)
Automated placement and withdrawal of parts and products Reduced errors and labor Particularly useful in inventory and test areas of manufacturing firms

22 Automated Guided Vehicle (AGVs)
Electronically guided and controlled carts Used for movement of products and/or individuals

23 Flexible Manufacturing Systems (FMSs)
Computer controls both the workstation and the material handling equipment Enhance flexibility and reduced waste Can economically produce low volume at high quality Reduced changeover time and increased utilization Stringent communication requirement between components

24 Computer-Integrated Manufacturing (CIM)
Extension of flexible manufacturing systems Backwards to engineering and inventory control Forward into warehousing and shipping Can also include financial and customer service areas Reducing the distinction between low-volume/high-variety, and high-volume/low-variety production

26 Technology in Services
Service Industry Example Financial Services Debit cards, electronic funds transfer, ATMs, Internet stock trading Education Electronic bulletin boards, on-line journals, WebCT and Blackboard Utilities and government Automated one-man garbage trucks, optical mail and bomb scanners, flood warning systems Restaurants and foods Wireless orders from waiters to kitchen, robot butchering, transponders on cars that track sales at drive-throughs Communications Electronic publishing, interactive TV Table 7.4

27 Technology in Services
Service Industry Example Hotels Electronic check-in/check-out, electronic key/lock system Wholesale/retail trade ATM-like kiosks, point-of-sale (POS) terminals, e-commerce, electronic communication between store and supplier, bar coded data Transportation Automatic toll booths, satellite-directed navigation systems Health care Online patient-monitoring, online medical information systems, robotic surgery Airlines Ticketless travel, scheduling, Internet purchases Table 7.4

28 Process Redesign The fundamental rethinking of business processes to bring about dramatic improvements in performance Relies on reevaluating the purpose of the process and questioning both the purpose and the underlying assumptions Requires reexamination of the basic process and its objectives Focuses on activities that cross functional lines Any process is a candidate for redesign

29 Ethics and Environmentally Friendly Processes
Reduce the negative impact on the environment Encourage recycling Efficient use of resources Reduction of waste by-products Use less harmful ingredients Use less energy
