Measuring Service Quality Using SERVQUAL

Introduction Measuring the quality of a service can be a very difficult exercise. Unlike product where there are specific specifications such as length, depth, width, weight, colour etc. a service can have numerous intangible or qualitative specifications. In addition there is there expectation of the customer with regards the service, which can vary considerably based on a range of factors such as prior experience, personal needs and what other people may have told them.

SERVQUAL – a methodology for measuring service quality As a way of trying to measure service quality, researchers have developed a methodology known as SERVQUAL – a perceived service quality questionnaire survey methodology. SERVQUAL examines five dimensions of service quality:
• Reliability
• Responsiveness
• Assurance;
• Empathy, and
• Tangible (e.g. appearance of physical facilities, equipment, etc.)
For each dimension of service quality above, SERVQUAL measures both the expectation and perception of the service on a scale of 1 to 7, 22 questions in total. Then, each of the five dimensions are weighted according to customer importance, and the score for each dimension multiplied by the weighting. Following this, the Gap Score for each dimension is calculated by subtracting the Expectation score from the Perception score. A negative Gap score indicates that the actual service (the Perceived score) was less than what was expected (the Expectation score).
The Gap score is a reliable indication of each of the five dimensions of service quality. Using SERVQUAL, service providers can obtain an indication of the level of quality of their service provision, and highlight areas requiring improvement.

The Methodology Outlined below are the instructions for carrying out a SERVQUAL survey, and a sample of the questions used in the questionnaire. In this sample, a bank is surveyed however, any service organisation can be surveyed using this
