23
Q

Four categories of the service triangle

A
  • the service strategy
  • the customer
  • employees
  • support systems
24
Q

Customer contact

A

interactions between the customer and service provided

25
extent of contact
% of time a customer is in the system compared to the service time - high contact; hair salon - low contact: automated car wash
26
Service capacity
Maximum amount of service that a service system or process can provide during a given period of time
27
Difference between service design and product design?
- the process is the product - lack legal protection - service package is defined by trained staff - services can be changed virtually overnight
28
service-system design matrix
defines the relationship between sales opportunity and production efficiency against the amount of customer contact - production efficiency decreases with more customer contact - los contact = system works more efficiently Lowest contact to highest - mail contact - internet - phone contact - f2f tight specs - f2f loose specs - f2f total customization
29
Pure virtual customer contact
customers interact in a digital environment - eBay - SeconLiife
30
mixed virtual and actual customer contact
Customer interact digitally and physically -e-commerce
31
Types of variability
the differences and fluctuations that can occur in various aspects of service delivery - arrival variability - request variability - capability variability - effort variability - subjective preference variability
32
Strategies to manage customer-introduced variability
- require reservations - persuade customers to compromise their requests - target customers on the basis of capability - use reward and penalties to get customers to increase their effort - persuade customers to adjust their expectations to match the value proposition
33
Arrival variability
Customers arriving at times when there are not enough service providers
34
Request variability
Differences in the specific service requests made by customers - Travelers requesting a room with a view
35
Capability variability
Differences in the skills and abilities of service providers - A patient being unable to explain symptoms to doctor
36
Effort variability
Differences in the effort made by customers to participate in the service process - Shoppers not putting up carts
37
Subjective preference variability
Differences in the subjective preferences of customers for aspects of the service process - Interpreting service action differently
38
Service guarantee
a formal promise made by a service provider to their customers that outlines the level of service that they can expect to receive and what will happen if the service provider fails to meet those expectations
39
Service blueprinting
process mapping tool used to understand and improve service processes it includes the line of visibility, which separates the front-office activities (visible to customers) from the back-office activities (not visible to customers) - helps to identify customer actions and interactions, and to ensure that the service design meets customer expectations
40
How to apply Poke-yoke in services
- warning methods - physical or visual contact methods - tangible features of the service
41
Characteristics of a well-designed service system
- user-friendly - robust - cost-effective - each element of the service process is consistent with the operating focus
42
3 contrasting service designs
- The production line approach - The self-service approach - The personal attention approach
43
The production line approach
Involves creating a standardized and efficient process for delivering services,
44
The self-service approach
Involves providing customers with the tools and resources they need to serve themselves
45
The personal attention approach
Involves providing personalized and individualized service to each customer
46
Cycle time
Average time between completions of units
47
Utilization
Ratio of: Time activated / time available
48
Process flowcharting
using a diagram to present elements of a process
49
Types of processes
- single stage - multiple stage
50
Single stage
activities could be analyzed using a single cycle time to represent the speed of the process
51
Multiple stage
group of activities that are linked through flows
52
Computer systems and networking terms
- buffer - blocking - starving - bottleneck
53
Buffering
temporarily storing data or information in a buffer, a designated area of memory or storage, before it is processed or transmitted
54
Blocking
process is unable to continue until a particular event or condition has been satisfied
55
Starving
process or resource is not receiving the necessary inputs or resources to continue executing properly
56
Bottleneck
stage that limits the capacity of the process (slows it down)
57
Pacing
having a fixed time for movement of items through the process
