Compared with the scholarly and practical attention paid to identify the consequences of implementing TQM practices, little is known about how those practices enhance organizational image and employee satisfaction. This paper aims to address that research gap and is designed to empirically prove the relationship between TQM practices, organizational image and employee satisfaction. Design/methodology/approach A questionnaire-based survey of 285 employees including administrators, managers and heads of departments of 21 National Accreditation Board for Hospital and Healthcare providers-accredited hospitals in India was conducted. The proposed research model was tested using partial least squares based structural equation modelling. Findings The results revealed that TQM practices have positive direct and indirect effects on employee satisfaction, confirming the partial mediation role played by organizational image in the relationship between TQM practices and employee satisfaction. Research limitations/implications From the findings, leaders can understand that by implementing TQM practices, organizations can enhance image of the organization and bring high level of employee satisfaction. Originality/value The study tries to answer questions largely ignored in the TQM literature: the effect of TQM practices on organizational image and employee satisfaction, and the mediating role of organizational image on TQM practices and employee satisfaction.","PeriodicalId":14403,"journal":{"name":"International Journal of Quality and Service Sciences","volume":"13 1","pages":"157-174"},"PeriodicalIF":2.6,"publicationDate":"2021-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43457966","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A case-study approach was used in this research to understand the effects of the Kaizen–Kata methodology in solving problems in their operational service process. Different Kaizen–Kata techniques and tools (histograms, Pareto chart and Ishikawa diagram) using the Plan, Do, Check, Act improvement cycle framework were used.,Successful implementation of the proposed methodology reduced the main impact of the problem’s effects (customer’s complaints, process reworking, extra-cost, delays, among others). The effects of the problem were reduced on average by 70%. Some Kaizen–Kata routines were identified in a service process environment.,The main limitation of the research is that this work is a just one-case study.

The authors define “methodological structure” to be comprising six categorical components: publication category, degree of methodological disclosure, research strategies and data collection instruments (DCIs), type of data collected and analysed and type of research informants. Design/methodology/approach This study is a systematic bibliometric analysis of the lean literature. It has a two-stage research design. The first stage involves the identification of the top 50 most highly cited publications on “Lean”, with the resultant reference details being entered into a focal population set (FPS) spread sheet. The second stage involves coding and adding the six component fields of the methodological structure for each of the FPS entries. Both citation analysis (CA) and publication counting are then used to analyse patterns in these six components of methodological structure. Findings The top 50 publications in the FPS represent over 52,700 citations. All are either journal papers or books, but books are the most influential. Based upon this FPS sample, the lean literature is found to be both largely atheoretical in nature and also methodologically weak. Over half of the FPS publications are viewpoint-type publications and 46% have no methodological disclosure. The lean literature is predominantly qualitative in nature. Where disclosed, the most common research strategy is the case study and the most common DCI is the interview. High- and mid-level managers are the most frequently encountered research informants, while shop floor workers are infrequently used. Originality/value This paper starts with the most extensive known systematic review of systematic reviews of the lean literature; the result of which is the characterisation of a number of gaps in this body of knowledge. One of these gaps is the lack of any previous CA. The paper then proceeds to address this gap by providing the first CA within the lean literature. This is also the most comprehensive known CA within the field of operations and supply chain management more generally. As a consequence of this analysis, previously unknown patterns and insights into the methodological structure of the lean literature are revealed.","PeriodicalId":14403,"journal":{"name":"International Journal of Quality and Service Sciences","volume":"1 1","pages":""},"PeriodicalIF":2.6,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"62013787","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Khan","doi":"10.1108/ijqss-06-2019-0090","DOIUrl":"https://doi.org/10.1108/ijqss-06-2019-0090","url":null,"abstract":"\u0000Purpose\u0000This paper aims to examine the effects of high-performance work practices (HPWPs) (participation, training and compensation) on nurses’ job performance (task and contextual) through the mediating role of job satisfaction. As nurses form the bulk of health-care professionals, their performance at work is crucial in determining patient satisfaction regarding care quality. HPWPs have been recognized as having the ability to affect employees’ work attitudes and behaviours positively. Specifically, these practices foster job performance.\u0000\u0000\u0000Design/methodology/approach\u0000Self-administered questionnaires were used to collect the survey data on 639 staff nurses working in large private hospitals in Malaysia. Data were subsequently analysed using the partial least squares method.\u0000\u0000\u0000Findings\u0000The findings indicate that job satisfaction serves to mediate the relationships between the three HPWPs (participation, training and compensation) and the two dimensions of job performance (task performance and contextual performance).\u0000\u0000\u0000Research limitations/implications\u0000First, as all variables were measured using self-reports, a common-method bias could exist (Podsakoff et al., 2003). Hence, future researchers may want to combine self-assessments and supervisory or peer assessment to improve the validity of the outcomes. Second, the cross-sectional nature of this study limits our ability to make causal inferences. Bias could happen because the study examined both exogenous and endogenous variables at the same time. Thus, a longitudinal approach taken in the future could cross-validate the current findings and provide additional support regarding the causality of the HPWPs-job performance relationship. Third, the data were collected from staff nurses working in large private hospitals in Peninsular Malaysia. Thus, one should be careful to generalize the findings to different health-care professional groups and organizations.\u0000\u0000\u0000Practical implications\u0000From the practical perspective, it is evident from the findings that as job satisfaction is able to enhance job performance and given the need for nurses to provide quality health-care services, private hospital authorities concerned with encouraging greater job performance among their nursing workforce need to provide adequate support to their employees. This could be achieved through the implementation of HPWPs. Perceptions of the extent of a hospital’s HPWPs in terms of participation, training and compensation, have significant and positive effects on nurses’ level of job satisfaction. Therefore, it would be worthwhile for private hospitals to encourage more opportunities for nurses to participate in decision-making regarding their work. In addition, frequent training activities will be able to enhance nurses’ knowledge, skills and abilities, resulting in greater satisfaction\u0000\u0000\u0000Originality/value\u0000To the best of the authors’ knowledge, this is the first attempt to investigate the effects of HPWPs on nurses’ job perfo","PeriodicalId":14403,"journal":{"name":"International Journal of Quality and Service Sciences","volume":"12 1","pages":"521-540"},"PeriodicalIF":2.6,"publicationDate":"2020-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1108/ijqss-06-2019-0090","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49604299","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
