Perishability
Services cannot be stored; once an airplane takes off or a movie starts, any unsold
seats cannot be held for future sale. Perishability is not a problem when demand for
a service is steady, but fluctuating demand can cause problems. For example, public-
transportation companies have to own much more equipment because of higher
rush-hour demand, just as Charles Schwab must have sufficient server capacity to han-
dle its brokerage customers’ on-line trading during peak stock market periods.
Service providers can deal with perishability challenges in a number of ways.
Table 4.3 shows some strategies proposed by Sasser for better matching demand and
supply in a service business.^9
MARKETING STRATEGIES FOR SERVICE FIRMS
In addition to the traditional four Ps of marketing, service providers must pay atten-
tion to three more Ps suggested by Booms and Bitner for services marketing: people,
physical evidence, and process.^10 Because most services are provided by people,the
selection, training, and motivation of employees can make a huge difference in cus-
tomer satisfaction. Ideally, service employees should exhibit competence, a caring atti-
tude, responsiveness, initiative, problem-solving ability, and goodwill.
Companies should also try to demonstrate their service quality through physical
evidenceand presentation. Thus, a hotel such as the Four Seasons will develop a look
Table 4.3 Strategies for Improving the Match between Demand and Supply
Demand-Side Strategies Supply-Side Strategies
Usedifferential pricingto shift demand from
peak to off-peak periods; movie theaters and
car rental firms do this by lowering prices
during off-peak periods.
Cultivate nonpeak demandto build sales during
off-peak periods; hotels do this with their
weekend minivacation packages.
Develop complementary servicesto provide
alternatives for customers during peak periods;
many banks do this by providing drop-off
boxes for deposits and payments.
Install reservation systemsto better manage
demand levels; airlines, hotels, and physicians
employ such systems extensively.
Hire part-time employeesto meet peak demand;
restaurants, stores, and Web-based businesses
often bring in temporary staffers to help out
during holidays and other peak periods.
Introduce peak-time efficiency routinesto keep
productivity high during periods of high
demand; paramedics often assist physicians
during busy periods.
Increase consumer participationto speed
transactions; this is one reason why
supermarkets are experimenting with self-
service checkouts where shoppers scan and
bag their own groceries.
Plan facilities for future expansionto increase
supply; an amusement park can buy
surrounding land for later development as
demand increases.
Share serviceswith other providers to help
manage demand; hospitals can do this by sharing
medical-equipment purchases and scheduling.
