2. Objective
(1) Describe the develpoment of a multiple-item scale for measuring service quality (called SERVQUAL,)
(2) Discuss the scale’s properties and potential applications.

3. Previous Work
Gronroos (1982); Lehtinen and Lehtinen(1982); Lewis and Booms (1983); Parasuraman, Zeithaml, and Berry (1985); Sasser, Olsen and Wyckoff(1978)
Service Quality stems from a comparison of what customers feel a company should offer (i.e., their expectations) with the company’s actual service performance.
Garvin (1983); Dodds and Monroe (1984); Holbrook and Corfman (1985); Jacoby and Olson (1985); Zeithaml (1987)
Emphasized the difference between objective and percieved quality.

4. Previous Work Holbrook and Corfman (1985) Garvin (1983)
Consumers do not use the term quality in the same way as researchers and merketers, who define it conceptually.
The conceptual meaning distinguishes between mechanistic and humanistic quality: “mechanistic (quality) involves an objective aspect or feature of a thing or event; humanistic (quality) involves an objective aspect or feature of a thing or event; humanistic (quality) involves the subjective response of people to objects and is therefore a highly relativistic phenomenon that differs between judges
Garvin (1983)
Five approaches to defining quality, including two (2) (product-based and manufacturing-based) that refer to objective quality and one (user- based) that parallels perceived quality.

5. Previous Work Parasuraman, Zeithaml, and Berry (1985)
Criteria used by customers in assessing service quality fit ten (10) dimensions:
Tangibles
Reliability
Responsiveness
Communication
Credibility
Security
Competence
Courtesy
Understanding / knowing the Customer
Access

6. Methodology Data Collection First Stage
200 Adult Respondents (25 years of age or older) recruited by a marketing research firm in a shopping mall in a large metropolitan area in the southwest.
Sample respondents were equally divided between males and females
Respondents were spread across five different service categories; appliance repair and maintenance, retail banking, long-distance telephone, securities brokerage, and credit cards.
To qualify for the study respondents had to have used the service in question during the past three months.
Screened and qualified respondents self administered a two part questionnaire consisting of a 97-statement expectations part followed by a 97-statement perceptions part.
The 97 item instrument eventually refined by analyzing pooled data. Coefficient alpha was computed separately for the 10 dimensions.

7. Methodology Scale Purification: First Stage Cont’d
Final pool of reduced down to 34 items representing seven distinct dimensions.
Five of the original 10 dimensions: Tangibles, reliability, responsiveness, understanding/knowing customers, and access remained distinct.
The remaining five dimensions: communication, credibility, security, competence and courtesy – collapsed into tow distinct dimensions.

8. Methodology Data Collection Second Stage
34- item scale and it’s psychometric properties data were collected pertaining to the service quality of four nationally known firms: A Bank, A credit-card company, a firm offering appliance repair and maintenance services, and a long-distance telephone company. 8 8

9. Methodology Scale Purification Second Stage
Content of the final items making up each of SERVQUAL’s five dimensions (three original and tow combined dimensions) suggested the following labels and concise definitions for the dimensions: 9 9

10. Methodology
Tangibles: Physical facilities, equipment, and appearance of personnel
Reliability: Ability to perform the promised service dependably and accurately
Responsiveness: Willingness to help customers and provide prompt service
Assurance*: Knowledge and courtesy of employees and their ability to inspire trust and confidence
Empathy*: Caring, individualized attention the firm provides it’s customers
*The last two dimensions (assurance and empathy) contain items representing seven original dimensions- Communication, Credibility, Security, Competence, Courtesy, Understanding/Knowing Customers, and Access

12. Results
SERVQUAL
Helps service & retailing organizations in assessing consumer expectations about and perceptions of service quality.
Helps pinpoint areas requiring managerial attention and action to improve service quality.
