Service Variability is an important characteristic of services: their quality can vary greatly depending on who provides them and when, where, and how. This makes standardization of services difficult.
The reason for variability is that services depend on the people who provide them (inseparability). Marketers combat this variability by 1) Investing in training and selecting staff; 2) Standardizing the delivery process (service blueprinting); and 3) Actively collecting customer feedback.
