Importance-performance analysis (IPA) for testing – and calibration – laboratories in India

Abstract

Purpose The purpose of this paper is to formulate the strategy for improving the laboratory practices to enhance customer satisfaction by analyzing the performance of critical factors of IS/ISO/IEC 17025 (2005) laboratory accreditation and the importance attached by the quality/technical managers in the accredited Indian testing/calibration laboratories. Design/methodology/approach The perceptions of the critical factors of laboratory accreditation and the importance attached by the quality/technical managers in their organizations have been collected and analyzed to develop an importance-performance analysis (IPA) model to enhance the customer satisfaction. Findings Findings report that the performance of the critical factors and the importance assigned to them are not the same. There exist gaps between the performance and importance which need to be measured and analyzed by the management to strive toward continual improvement to enhance the customer satisfaction through the accredited testing and calibration services. Research limitations/implications This study is restricted to 54 responses out of 150 which were sent (i.e. about 36 percent response rate) to capture the perspectives of the quality/technical managers. Practical implications This study would enable the accredited laboratories to analyze the gap in performance and the importance assigned to critical factors through the feedback from the quality/technical managers. By analyzing the strengths and weaknesses in the accredited testing/calibration laboratories, managerial decisions and strategic plans can be proposed to gain greater insights into benchmarking improvement of the laboratory quality management system with the existing resources to strive toward customer satisfaction. Originality/value This paper proposes IPA as a tool to assess the gap between the importance and performance of critical factors of accredited testing and calibration laboratories in India.
