Service quality is determined by whether a customer's expectations are met or exceeded based on their experience. Expectations are shaped by marketing, past experiences, and word of mouth. Experience is built through a series of interactions, or "moments of truth." If experience meets or exceeds expectations, quality is good or great. But if expectations are not met, quality is poor. Both the process and outcome of service delivery impact experience. Managing expectations and consistently meeting them over time builds strong customer relationships and service quality.
