Service quality is perceived to have deteriorated
Optimum capacity
Staff is not overworked and customers receive good service

Addressing Problem of Fluctuating Demand
Two basic approaches of which most firms use a mix of:
Adjust level of capacity to meet demand
Need to understand productive capacity and how it varies on an incremental basis
Manage level of demand
Use marketing strategies to smooth out peaks, fill in valleys
Inventorying demand until capacity becomes available

Managing Capacity
Enables more people to be served at same level of capacity
Stretch and shrink:
Offer inferior extra capacity at peaks (e.g., bus/train standees)
Use facilities for longer/shorter periods
Reduce amount of time spent in process by minimizing slack time
Adjusting capacity to match demand
Rest during low demand
Cross-train employees
Use part-time employees
Customers perform self-service
Ask customers to share
Create flexible capacity
Rent/share facilities and equipment

18
Waiting Is a Universal Phenomenon!
An average person may spend up to 30 minutes/day waiting in line—equivalent to over one week per year!
Nobody likes to wait
It’s boring, time-wasting, and sometimes physically uncomfortable

19
Why Do Waiting Lines Occur?
Because number of arrivals at a facility exceeds capacity of system to process them at a specific point in the process
Queues are basically a symptom of unresolved capacity management problems
Not all queues take form of a physical waiting line in a single location
Queues may be physical but geographically dispersed
Some are virtual (e.g., phone)

Benefits of Reservations
Saves customers from having to wait in line
Helps to control and manage the demand (e.g., leave time for emergency jobs)
Pre-sells the service and can be used to prepare and educate the customer for the service encounter
Data captured helps organizations to understand their demand patterns and to plan their operations and staffing levels

Characteristics of Well-Designed Reservations System
Fast and user-friendly for customers and staff
Responsive to customer queries and needs
Offers options for self service (e.g., through an online reservations system)
Accommodates preferences (e.g., room with a view)
Deflects demand from unavailable first choices to alternative times and locations

Reservations Strategies Should Focus on Yield
Yield analysis helps managers recognize opportunity cost of allocating capacity to one customer/segment when another segment might yield a higher rate later
Decisions need to be based on good information
Detailed records of past usage
Current market intelligence and good marketing sense
Realistic estimate of the chances of obtaining higher rated business
When firms overbook to increase yield,
Victims of overbooking should be compensated to preserve the relationship

Historical data on demand level and composition, marketing variables
Demand forecasts by segment under specified conditions
Segment-by-segment data
Fixed and variable cost data, profitability of incremental sales
Meaningful location-by-location demand variations
Customer attitudes towards queuing
Customer opinions of quality at different levels of capacity utilization
Summary
At any moment in time, a fixed-capacity service may face
Excess demand
Demand exceeding optimum capacity
Demand and supply well-balanced at the level of optimum capacity
Excess capacity
To balance demand and capacity, a firm can:
Manage capacity
Take no action and let demand find its own levels
Reduce demand in peak periods
Increase demand when there is excess capacity
Inventory demand using wait & queuing, and reservation systems
Capacity can be managed through:
Stretching or shrinking capacity levels
Adjusting capacity to match demand
Creating flexible capacity
