Evaluating the elements of just in time (JIT) for implementation in maintenance by exploratory and confirmatory factor analysis

摘要

Purpose The purpose of this paper is to propose a model (structural equation modeling (SEM)) from the16 identified just in time (JIT) elements useful for implementation of JIT in maintenance.Design/methodology/approach - Data were collected using questionnaires posted to 421 manufacturingindustries and automotive service industries in India from which 133 usable responses were obtained. First,exploratory factor analysis (EFA) is carried out to identify the factor structure after that confirmatory factoranalysis (CFA) is carried out to verify the factor structure of a set of identified JIT elements. CFA is concededby an SEM statistical technique. In this paper, EFA is applied to extract the factors in JIT implementation bythe statistical package for social sciences (SPSS 24) software and confirming these factors by CFA throughanalysis of moment structures (AMOS 18) software.Findings - Out of 18 identified JIT elements through literature and expert opinion only 16 JIT elements areselected for the study, two JIT elements removed due to the low value of correlation item-total correlation(CITC). Three factors extracted through EFA, which affects the benefits of JIT implementation inmaintenance in quality improvement, production improvement and process control. SEM using AMOS 18.0was used to perform the first-order three-factor structure (quality improvement, production improvement andprocess control) of the JIT implementation in maintenance.Originality/value - The results will be useful for maintenance managers and maintenance professionals tounderstand the process of implementation of JIT in maintenance and to gain benefits after the implementationof JIT in maintenance in their respective organization.
