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

7–2
Changing Processes
 Difficult and expensive
 May mean starting over
 Process strategy determines
transformation strategy for an
extended period
 Important to get it right

7–3
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
