Research Objectives and Thematic Focus

The primary objective of this research is to empirically investigate whether the two prominent service quality measurement instruments, SERVQUAL and SERVPERF, yield concurrent results or differ significantly when applied to the higher education sector, specifically an engineering institute.

• Comparative analysis of SERVQUAL (perception-minus-expectation) and SERVPERF (perception-only) metrics.
• Assessment of service quality dimensions: Reliability, Assurance, Tangibility, Empathy, and Responsiveness.
• Statistical validation of measurement instruments through reliability testing, factor analysis, t-tests, and ANOVA.
• Identification of service quality gaps and formulation of improvement strategies for educational institutions.

Frequently Asked Questions

What is the core focus of this research?

The research focuses on conducting a comparative empirical study of the two most widely used service quality metrics, SERVQUAL and SERVPERF, to determine if they produce consistent results.

Which service sector is used for this empirical study?

The study is conducted within the higher education sector, specifically analyzing service quality in a private engineering college.

What is the primary difference in philosophy between the two metrics?

SERVQUAL defines service quality as the gap between customer perception and expectation (P-E), whereas SERVPERF measures service quality solely based on customer perception.

Which statistical methods are employed to analyze the data?

The study utilizes descriptive statistics, Cronbach’s Alpha for reliability, factor analysis, rank order correlation, paired sample t-tests, and Analysis of Variance (ANOVA).

What is the main finding regarding the concurrence of these metrics?

The research concludes that there is a significant difference in the outcomes of SERVQUAL and SERVPERF; they do not concur, implying they measure service quality differently.

What are the identified key dimensions of service quality?

The five key dimensions analyzed are Reliability, Assurance, Tangibility, Empathy, and Responsiveness.

Why were the standard metrics modified for this research?

The original instruments were designed for general service sectors; therefore, modifications were necessary to tailor the items to the specific educational context of an engineering institute.

What are the practical implications for engineering institutes?

The study suggests that institutions should prioritize enhancing 'Human Factors', specifically focusing on Empathy (individualized student attention) and Assurance (faculty training), which were identified as weaker dimensions.
