Final answer:
Services are known to have a high degree of variability due to their tailored nature and differences that emerge with every individual service instance.
Step-by-step explanation:
Because a service is individually produced and is virtually unique, the service is said to have a high degree of variability. Services are characterized by their intangibility, inseparability, perishability, and variability. Unlike products which can be made uniform through manufacturing processes, services are often tailored to individual needs and can differ each time they are delivered. Consider services like healthcare, consulting, or education; each instance of service provided can vary based on different factors such as the provider, the customer, and the circumstances of delivery.
