Learning Objectives Describe the impact of the “servicescape” on the behavior of
customers and employees. Identify and discuss the three environmental dimensions of
servicescapes. Identify the six critical design features of a service supporting
facility. Draw a process flow diagram and calculate performance
metrics. Identify the bottleneck operation in a product layout and
rebalance for increased capacity. Use operations sequence analysis to minimize flow-distance
in a process layout. Recommend facility design features to remove anxiety of
disorientation.

Servicescapes Designing Physical Surroundings to Affect
Employee and Customer Behavior Ambient Conditions: background characteristics
such as noise level, music, lighting, temperature, and scent.
Spatial Layout and Functionality: reception area, circulation paths of employees and customers, and focal points.
Signs, Symbols, and Artifacts: selection, orientation, location, and size of objects.

Process Analysis Terminology
Cycle Time is the average time between completions of successive units.
Bottleneck is the factor that limits production usually the slowest operation.
Capacity is a measure of output per unit time when fully busy.
Capacity Utilization is a measure of how much output is actually achieved.
Throughput Time is the time to complete a process from time of arrival to time of exit.

Process Analysis Terminology (cont.)
Rush Order Flow Time is the time to go through the system without any queue time.
Direct Labor Content is the actual amount of work time consumed.
Total Direct Labor Content is the sum of all the operations times.

Environmental Orientation Considerations
Need for spatial cues to orient visitors Formula facilities draw on previous
experience Entrance atrium allows visitors to gain a
quick orientation and observe others for behavioral cues
Orientation aids and signage such as “You Are Here” maps reduce anxiety

HMO (A) QUESTIONS
1. Beginning with a good initial layout, use operations sequence analysis to determine a better layout that would minimize the walking distance between different areas of the clinic.
2. Defend your final layout based on features other than minimizing walking distance.

Esquire Department Store
1. Use CRAFT logic to develop a layout that will maximize customer time in the store.
2. What percentage increase in customer time spent in the store is achieved by the proposed layout?
3. What other consumer behavior concepts should be considered in the relative location of departments?

“There’s cheese at the end of the maze…”
Questions1. How do the environmental dimensions of
the servicescape (ambient conditions, space/function, signs, symbols & artifacts) explain the success of Central Market?
2. Comment on how the servicescape shapes the behaviors of both customers and employees?

Topics for Discussion Compare the attention to aesthetics in waiting rooms that you
have visited. How did the different environments affect your mood?
Give an example of a servicescape that supports the service concept and another that detracts. Explain the success or failure in terms of the servicescape dimensions
Select a service and discuss how the design and layout of the facility meets the five factors of nature and objectives of the organization.
For Example 9.3, the Ocean World theme park, make an argument for not locating popular attractions next to each other.
The CRAFT program is an example of a heuristic programming approach to problem solving. Why might CRAFT not find the optimal solution to a layout problem?

Interactive Exercise
The class divides into small groups One-half of the groups produce
examples based on work experience with supportive servicescapes in terms of job satisfaction and productivity.
The other one-half of the groups provide examples of poor servicescapes in terms of job satisfaction and productivity.
