Some doctors charge patients for missed appointments because the service value existed only at that point and disappeared when the patient did not show up, which is an example of Perishability.Perishability “ Characteristics of ServicesPerishability means that services cannot be stored for later sale or use.In other words, services cannot be inventoried.This is one of the most significant characteristics of services, since it may have a major impact on financial results.Doctors or dentists often charge patients for missed appointments because the service value has foregone. The value existed only at that particular point and disappeared when the patient did not come.When demand is steady, the perishability of services is not a problem.However, in the case of fluctuating demand, service firms can have difficult problems.For this reason, transport companies own much more equipment than they would if demand were even throughout the day: the demand during rush-hours needs to be served at that specific time, it cannot be served later or earlier. 1. Inseparability “ Characteristics of ServicesCharacteristics of services include inseparability, which means that services are produced and consumed at the same time.This also entails that services cannot be separated from their providers.Contrary to services, physical goods are produced, then stored, later sold, and even later consumed.Services are first sold, then produced and consumed at exactly the same time. 2. Intangibility “ Characteristics of ServicesWhen thinking about the characteristics of services, intangibility may come to your mind first.Service intangibility means that services cannot be seen, tasted, felt, heard, or smelled before they are bought.You cannot try them out.For instance, airline passengers have nothing but a ticket and a promise that they will arrive at a certain time at a certain destination. But there is nothing that can be touched.3. Variability “ Characteristics of ServicesVariability does also belongs to the important characteristics of services.It refers to the fact that the quality of services can vary greatly, depending on who provides them and when, where, and how. Because of the labor-intensive nature of services, there is a great deal of difference in the quality of service provided by various providers, or even by the same providers at different times.
