“…For measuring the service quality, a 22-item questionnaire instrument called SERVQUAL was proposed by Parasuraman et al [1]. Since then, the SERVQUAL questionnaire has been used to analyze service quality within diverse organizations, such as retailing organizations [2], airline industry [3], restaurants [31], hotel [4,23,33], higher education [5,26], urban transportation [6,7], public or private health care [8,9,10,11,27,35], information system [12], e-learning [14], hot spring industry [13,37], condominium management [28,32], Internet service [14,24,29,36], supply chain [15], banking [16]; [21], logistics industry [17], alcohol treatment [34], enterprise resource planning (ERP) systems [18], library [30], telecommunication sector [5], tourism industry [19], online travel agencies [22], after-sale Service in Manufacturing [25], public service [20], crisis and emergency management [38], and so on. But SERVQUAL has not been applied to certification & inspection industry so far.…”
