Learning Objective 4.11
Differences between Service and Product Design
Products are generally tangible, services intangible
Services are created and delivered at the same time
Services cannot be inventoried
Services are highly visible to consumers
Some services have low barriers to entry and exit
Location is often important to service design, with convenience as a major factor
Service systems range from those with little or no customer contact to those that have a very high degree of customer contact
Demand variability alternately creates waiting lines or idle service resource
