SERVQUAL or Gaps Model

There are seven major gaps in the service quality concept, which are shown in Figure 1. The model is an extention of Parasuraman et al. (1985). According to the following explanation the three important gaps, which are more associated with the external customers are Gap1, Gap5 and Gap6; since they have a direct relationship with customers.

· Gap1: Customers’ expectations versus management perceptions: as a result of the lack of a marketing research orientation, inadequate upward communication and too many layers of management.

· Gap2: Management perceptions versus service specifications: as a result of inadequate commitment to service quality, a perception of unfeasibility, inadequate task standardisation and an absence of goal setting.

· Gap3: Service specifications versus service delivery: as a result of role ambiguity and conflict, poor employee-job fit and poor technology-job fit, inappropriate supervisory control systems, lack of perceived control and lack of teamwork.


· Gap4: Service delivery versus external communication: as a result of inadequate horizontal communications and propensity to over-promise.


· Gap5: The discrepancy between customer expectations and their perceptions of the service delivered: as a result of the influences exerted from the customer side and the shortfalls (gaps) on the part of the service provider. In this case, customer expectations are influenced by the extent of personal needs, word of mouth recommendation and past service experiences.


· Gap6: The discrepancy between customer expectations and employees’ perceptions: as a result of the differences in the understanding of customer expectations by front-line service providers.

· Gap7: The discrepancy between employee’s perceptions and management perceptions: as a result of the differences in the understanding of customer expectations between managers and service providers.

The SERVQUAL instrument has been the predominant method used to
measure consumers’ perceptions of service quality. It has five generic dimensions or factors and are stated as follows (van Iwaarden et al., 2003):

(1) Tangibles. Physical facilities, equipment and appearance of personnel.

(2) Reliability. Ability to perform the promised service dependably and accurately.

(3) Responsiveness. Willingness to help customers and provide prompt service.

(4) Assurance (including competence, courtesy, credibility and security). Knowledge and courtesy of employees and their ability to inspire trust and confidence.

(5) Empathy (including access, communication, understanding the customer). Caring and individualized attention that the firm provides to its customers.

Services Marketing

A service is the action of doing something for someone or something. It is largely intangible (i.e. not material). A product is tangible (i.e. material) since you can touch it and own it. A service tends to be an experience that is consumed at the point where it is purchased, and cannot be owned since is quickly perishes. A person could go to a café one day and have excellent service, and then return the next day and have a poor experience. So often marketers talk about the nature of a service as:

Inseparable - from the point where it is consumed, and from the provider of the service. For example, you cannot take a live theatre performance home to consume it (a DVD of the same performance would be a product, not a service).

Intangible - and cannot have a real, physical presence as does a product. For example, motor insurance may have a certificate, but the financial service itself cannot be touched i.e. it is intangible.

Perishable - in that once it has occurred it cannot be repeated in exactly the same way. For example, once a 100 metres Olympic final has been run, there will be not other for 4 more years, and even then it will be staged in a different place with many different finalists.

Variability- since the human involvement of service provision means that no two services will be completely identical. For example, returning to the same garage time and time again for a service on your car might see different levels of customer satisfaction, or speediness of work.

Right of ownership - is not taken to the service, since you merely experience it. For example, an engineer may service your air-conditioning, but you do not own the service, the engineer or his equipment. You cannot sell it on once it has been consumed, and do not take ownership of it.

Western economies have seen deterioration in their traditional manufacturing industries, and a growth in their service economies. Therefore the marketing mix has seen an extension and adaptation into the extended marketing mix for services, also known as the 7P's - physical evidence, process and people.

Lets now look at the remaining 3 p’s:

People

An essential ingredient to any service provision is the use of appropriate staff and people. Recruiting the right staff and training them appropriately in the delivery of their service is essential if the organisation wants to obtain a form of competitive advantage. Consumers make judgements and deliver perceptions of the service based on the employees they interact with. Staff should have the appropriate interpersonal skills, aptititude, and service knowledge to provide the service that consumers are paying for. Many British organisations aim to apply for the Investors In People accreditation, which tells consumers that staff are taken care off by the company and they are trained to certain standards.

Process

Refers to the systems used to assist the organisation in delivering the service. Imagine you walk into Burger King and you order a Whopper Meal and you get it delivered within 2 minutes. What was the process that allowed you to obtain an efficient service delivery? Banks that send out Credit Cards automatically when their customers old one has expired again require an efficient process to identify expiry dates and renewal. An efficient service that replaces old credit cards will foster consumer loyalty and confidence in the company.

Physical Evidence

Where is the service being delivered? Physical Evidence is the element of the service mix which allows the consumer again to make judgements on the organisation. If you walk into a restaurant your expectations are of a clean, friendly environment. On an aircraft if you travel first class you expect enough room to be able to lay down!
Physical evidence is an essential ingredient of the service mix, consumers will make perceptions based on their sight of the service provision which will have an impact on the organisations perceptual plan of the service.
