BALANCING DEMAND AND PRODUCTIVE CAPACITYDIMPLE UDANI
Fluctuations in Demand Threaten Service Productivity
Productive Capacity and Service Success Services cannot be stockpiled This is problematic for people or
physical possession services due to wide swings in demand Goal is to utilize staff, equipment, and facilities as productively as possible
Service Decision Framework: Decisions on Matching Demand and CapacityWhat Business Are We In? What Service Processes Can Be Used in Our Operation? (PROCESS) Who Are Our Customers and How Should We R elate to Them?
What Should be the Core and Supplementary Elements of Our Service Product? (PRODUCT ELEMENTS) What Price Should We Charge? (PRICE AND OTHER USER OUTLAYS) Options for Delivery? (PLACE, CYBERSPACE & TIME, PHYSICAL EVIDENCE) How to Communicate? (PROMOTION & EDUCATION, PHYSICAL EVIDENCE) How Can We Balance PRODUCTIVITY AND QUALITY?
H OW SHOULD WE M ATCH DEMAND AND PRODUCTIVE CAPACITY? What Are Appropriate R oles for People and T echnology? (PEOPLE) How Can Our Firm Achieve Service Leadership?
How Should We Match Demand and Productive Capacity? How do we define our productive capacity? (e.g.,
buildings, physical space, machines, brawn, brains?) What are demand levels for our service and do they exceed capacity at any time? What explains variations in demand? What strategies can we employ to match demand and capacity? How should we design waiting lines and reservations systems?
From Excess Demand to Excess CapacityFour conditions potentially faced by fixed-capacity services: Excess demand Too much demand relative
to capacity at a given time
Demand exceeds optimum
capacity Maximum Capacity
Upper limit to a firms
ability to meet demand at a given time service quality declines as more customers are serviced
Optimum capacity Point beyond which
Excess capacity
Addressing the Problem of Fluctuating DemandTwo basic approaches: Adjust level of capacity to meet demand Need to understand productive capacity and how it varies on an incremental
Variations in Demand Relative to Capacity Use marketing strategies to
smooth out peaks, fill in VOLUME DEMANDED valleys Many firms use a mix ofCAPACITY UTILIZED
Demand exceeds capacity (business is lost) bothDemand exceeds optimum capacity (quality declines)
approaches
Maximum Available Capacity Optimum Capacity (Demand and Supply Well Balanced)
Low Utilization (May Send Bad Signals)
(wasted resources) TIME CYCLE 1
Excess capacity
TIME CYCLE 2
Many Service Organizations Are Capacity Constrained
Defining Productive Capacity in Services Physical facilities to contain customers Physical facilities to store or process goods
Physical equipment to process people, possessions, or
information Labor used for physical or mental work Public/private infrastructure
Alternative Capacity Management Strategies Level capacity (fixed level at all times) Stretch and shrink Offer inferior extra capacity at peaks (e.g., bus/train
standees) room)
Vary seated space per customer (e.g., elbow room, leg Extend/cut hours of service
Chase demand (adjust capacity to match demand)
Flexible capacity (vary mix by segment)
Adjusting Capacity to Match Demand
Schedule downtime during periods of low demand Use part-time employees Rent or share extra facilities and equipment Ask customers to share Invite customers to perform self-service Cross-train employees
Patterns and Determinants of Demand
Predictable Demand Patterns and Their Underlying CausesPredictable Cycles of Demand Levels day week
Underlying Causes of Cyclical Variations employment billing or tax
month year other
payments/refunds pay days school hours/holidays seasonal climate changes public/religious holidays natural cycles (e.g., coastal tides)
Causes of Seemingly Random Changes in Demand Levels Weather Health problems Accidents, Fires, Crime
Natural disasters
Question: Which of these events can be predicted?
Analyzing Drivers of Demand Understand why customers from specific
market segments select this service Keep good records of transactions to analyze demand patterns Sophisticated software can help to track
customer consumption patterns Record weather conditions and other
special factors that might influence demand
Overall Usage Levels Comprise Demand from Different Segments Not all demand is desirable
Keep peak demand levels within service capacity of
organization Marketing cannot smooth out random fluctuations in demand Fluctuations caused by factors beyond organizations
control (for example: weather) Detailed market analysis may reveal that one segments demand cycle is concealed within a broader, random pattern
Analyzing Demand by Market Segment Different customers have different demand
patterns by day or by season (e.g., business travelers vs. tourists) Some users have little choice in timing of demand, others are flexible (e.g. commuters vs. shoppers) Some demand is undesirable and should be discouraged (e.g., inappropriate calls to emergency services)

Demand Levels Can Be Managed
Alternative Demand-Management Strategies Take no action
Let customers sort it out Reduce demand
Higher prices Communication promoting
alternative times
Increase demand
Lower prices Communication, including
promotional incentives Vary product features to increase desirability More convenient delivery times and places
Inventory demand by reservation
system Inventory demand by formalized queuing
Marketing Strategies Can Reshape Some Demand Patterns
Use price and other costs to manage demand Change product elements
Modify place and time of delivery No change Vary times when service is available Offer service to customers at a new location

Inventory Demand through Waiting Lines and Reservations
Waiting Is a Universal Phenomenon! An average person may spend up to 30 minutes/day
waiting in lineequivalent to over a week per year! Almost nobody likes to wait It's boring, time-wasting, and sometimes physically uncomfortable
Why Do Waiting Lines Occur? Because the 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
Saving Customers from Burdensome Waits Add extra capacity so that demand can be met at most
times (problem: may increase costs too much) Rethink design of queuing system to give priority to
certain customers or transactions Redesign processes to shorten transaction time Manage customer behaviour and perceptions of wait Install a reservations system
Alternative Queue ConfigurationsSingle line, single server, single stage
Single line, single servers, sequential stages
Parallel lines to multiple servers Designated lines to designated servers Single line to multiple servers (snake)28 29 25 26 27 32 23 21 20 24

Criteria for Allocating Different Market Segments to Designated Lines Urgency of job Emergencies versus non-
emergencies Duration of service transaction Number of items to transact Complexity of task
Payment of premium price First class versus economy
Importance of customer Frequent users/high volume
purchasers versus others
Minimize Perceptions of Waiting Time
Ten Propositions on Psychology of Waiting Lines1.Unoccupied time feels longer than occupied time 2. Pre- and post-process waits feel longer than in-process waits 3. Anxiety makes waits seem longer 4. Uncertain waits are longer than known, finite waits 5. Unexplained waits are longer than explained waits
Ten Propositions on Psychology of Waiting Lines6. Unfair waits are longer than equitable waiting 7. People will wait longer for more valuable services 8. Waiting alone feels longer than waiting in groups 9. Physically uncomfortable waits feel longer 10. Waits seem longer to new or occasional users
Create an Effective Reservation System
Benefits of Reservations Controls and smoothes demand Pre-sells service Informs and educates customers in advance of arrival Saves customers from having to wait in line for service
(if reservation times are honored) Data captured helps organizations Prepare financial projections Plan operations and staffing levels
Characteristics of Well-Designed Reservations System Fast and user-friendly for customers and staff Answers customer questions Offers options for self service (e.g., the Web) Accommodates preferences (e.g., room with view) Deflects demand from unavailable first choices to
alternative times and locations Includes strategies for no-shows and overbooking Requiring deposits to discourage no-shows Canceling unpaid bookings after designated time Compensating victims of over-booking
