Final answer:
Customers are more likely to change how they define desired levels of service compared to how adequate levels of service are defined.
Step-by-step explanation:
The statement is true. How a customer defines desired levels of service is more likely to change than how adequate levels of service are defined.
When it comes to desired levels of service, customers' expectations and needs may vary over time. For example, as technology advances, customers may expect faster delivery times or more personalized interactions. These changing preferences can result in a shift in how customers define their desired levels of service.
On the other hand, adequate levels of service are generally defined by industry standards and customer feedback. These standards and feedback provide a baseline for businesses to meet customer expectations.
While the specific metrics for measuring adequate levels of service may be adjusted based on customer feedback, the general definition of adequacy tends to remain more stable compared to desired levels of service.
