Answer:
consistency.
Step-by-step explanation:
A service can be defined as an intangible (immaterial), non-physical activities, satisfactions or benefits that are offered for sale by a business service or provided to accompany the sales of a product. Thus, it's an action that involves offering something to a service taker or customer in return for an amount of money as payment.
Basically, a service is expected to have certain characteristics and these includes;
I. Intangibility.
II. Heterogeneity.
III. Perishability.
IV. Lack of ownership.
V. Inseparability.
VI. Variability.
VIII. Quality management.
In this scenario, one of the ways Andrea Arenas tries to ensure consistency of services for her regular customers is to ensure that the same well-trained person (employee) is always assigned to work for them.
This ultimately implies that, she ensures her regular customers get the same level of quality service at all times by assigning a well-trained person (employee) to work for them.
