Purpose Nowadays, the phenomenon of increased competition between firms and their need to respond effectively to rapidly changing operational conditions, as well as to personnel requirements, has escalated the necessity to identify those factors that affect employee performance (EP). The purpose of this paper is to examine the interrelations between firm/environment-related factors (training culture, management support, environmental dynamism and organizational climate), job-related factors (job environment, job autonomy, job communication) and employee-related factors (intrinsic motivation, skill flexibility, skill level, proactivity, adaptability, commitment) and their impact on EP. Design/methodology/approach A new research model that examines the relationships between these factors and EP is proposed utilizing the structural equation modeling approach. Findings The results indicate that job environment and management support have the strongest impacts (direct and indirect) on job performance, while adaptability and intrinsic motivation directly affect job performance. Research limitations/implications A potential limitation of this research is that it is not focused only on one business sector (i.e. the sample is heterogeneous). Originality/value In this study, firm/environmental-related factors, job-related factors, employee-related factors and EP are incorporated in a single model using data from small- and medium-sized enterprises. Overall, the final model can explain 27 percent of EP variance (first-level analysis) and 42 percent of EP variance (second-level analysis).

Purpose -This paper aims to develop an understanding of the factors that influence knowledge-sharing behaviour within an organisational framework, using widely accepted social psychology theories. Design/methodology/approach -Knowledge-sharing behaviour of bank employees in Greece is examined using an aggregate model, which is based on the theory of planned behaviour. The suggested research model was tested using structural equation modelling. Findings -The results indicate that intention to share knowledge is mainly influenced by employees' attitude toward knowledge sharing, followed by subjective norms. Research limitations/implications -Knowledge-sharing behaviour was examined solely focusing on salient beliefs. Findings should be confirmed using a larger sample, as well as through cross-sectional studies. Practical implications -The results highlight the necessity of creating a climate that would help individuals develop a more favourable attitude toward knowledge sharing as well as the important role of the perceived social pressure by organisational members (peers, supervisors, senior management) on the intention of individuals to share knowledge. Originality/value -The main contributions of this study are the following: examination of the knowledge sharing in the banking sector; testing of a specific well-known research model in the South-Eastern European environment; examination of the actual knowledge-sharing behaviour and not only of the behavioural intention to share knowledge and, finally, examination of the direct effect of the perceived behavioural control on knowledge-sharing behaviour, which, although suggested by theory, has been neglected by previous studies.

Purpose Nowadays, innovation appears as one of the main driving forces of organisational success. Despite the above fact, its impact on the propensity of an organisation to develop and sustain a competitive advantage has not yet received sufficient empirical investigation. The purpose of this paper is to enhance the existing empirical literature by focusing on the antecedents of innovation and its impact on competitive advantage. It proposes a newly developed conceptual framework that adopts a three-step approach, highlighting areas that have rarely been simultaneously examined before. Design/methodology/approach The examination of the proposed conceptual framework was performed with the use of a newly developed structured questionnaire that was distributed to a group of Greek manufacturing companies. The questionnaire has been successfully completed by chief executive officers (CEOs) from 189 different companies. CEOs were used as key respondents due to their knowledge and experience. The reliability and the validity of the questionnaire were thoroughly examined. Empirical data were analysed using the structural equation modelling technique. The study is empirical (based on primary data), explanatory (examines cause and effect relationships), deductive (tests research hypotheses) and quantitative (includes the analysis of quantitative data collected with the use of a structured questionnaire). Findings Results indicate that knowledge management, intellectual capital, organisational capabilities and organisational culture have significant direct and indirect effects on innovation, underlining the importance of their simultaneous enhancement. Finally, the positive effect of innovation on the creation of competitive advantages is empirically validated, bridging the gap in the relevant literature and offering avenues for additional future research. Originality/value The causal relationship between innovation and competitive advantage, despite its significant theoretical support, has not been empirically validated. The present paper aspires to bridge this gap, investigating the impact of innovation on the development of competitive advantages. Moreover, the present study adopts a multidimensional approach that has never been explored in the existing innovation literature, making the examination of the proposed conceptual framework an interesting research topic.

Over the past decade, hospitals in Greece have made significant investments in adopting and implementing new hospital information systems (HISs). Whether these investments will prove beneficial for these organizations depends on the support that will be provided to ensure the effective use of the information systems implemented and also on the satisfaction of its users, which is one of the most important determinants of the success of these systems. Measuring end-user computing satisfaction has a long history within the IS discipline. A number of attempts have been made to evaluate the overall post hoc impact of HIS, focusing on the end-users and more specifically on their satisfaction and the parameters that determine it. The purpose of this paper is to build further upon the existing body of the relevant knowledge by testing past models and suggesting new conceptual perspectives on how end-user computing satisfaction (EUCS) is formed among hospital information system users. All models are empirically tested using data from hospital information system (HIS) users (283). Correlation, explanatory and confirmation factor analysis was performed to test the reliability and validity of the measurement models. The structural equation modeling technique was also used to evaluate the causal models. The empirical results of the study provide support for the EUCS model (incorporating new factors) and enhance the generalizability of the EUCS instrument and its robustness as a valid measure of computing satisfaction and a surrogate for system success in a variety of cultural and linguistic settings. Although the psychometric properties of EUCS appear to be robust across studies and user groups, it should not be considered as the final chapter in the validation and refinement of these scales. Continuing efforts should be made to validate and extend the instrument.

Purpose – The purpose of this paper is to explore the relationship between the acquisition of an ISO 9000 certification and the overall financial performance of the certified firms. More specifically, the study proposes a multidimensional conceptual framework, including “customers’ demand”, “ISO adoption”, “operation efficiency”, “market efficiency” and “overall financial performance”. Such a multidimensional approach has randomly been explored in the existing literature, making the examination of the proposed conceptual framework an interesting research topic. Design/methodology/approach – The proposed conceptual framework was tested on a sample of Greek ISO 9000-certified companies of various economic sectors. Quality managers were used as key respondents. The final sample consisted of 168 companies. The reliability and the validity of the questionnaire were thoroughly examined. Empirical data were analyzed using the structural equation modelling technique. The findings are based on the 2000 version of the ISO series, which is generally accepted and has widespread use, as it has eliminated most of the disadvantages of the 1994 version. The present study is empirical (it is based on primary data), explanatory (examines cause and effect relationships), deductive (tests research hypotheses) and quantitative (includes the analysis of quantitative data collected with the use of a structured questionnaire). Findings – The findings of the study provide strong evidence that ISO 9000 implementation is highly associated with improvements in overall financial performance. Moreover, it was found that ISO implementation is directly associated with significant improvements in quality awareness, operations execution, market share, customer satisfaction and sales revenue. Finally, customers’ demand was not found to be the most important motivation for implementing an ISO certification. Rather, it seems that companies seek for quality improvement due to internal motives. Research limitations/implications – A limitation stemming from the implemented methodology is the use of self-report scales to measure the constructs of the proposed model. Moreover, the present paper lacks a longitudinal approach, since it is cross-sectional and provides a static picture of ISO implementation. Practical implications – The paper makes an analytical effort in order to point out areas that companies should emphasize in order to successfully implement ISO 9000 and, therefore, harvest its potential benefits. Certain practical implications are offered in the final part of the paper. Originality/value – The paper proposes an enhanced conceptual framework that examines vital issues concerning the successful implementation of ISO 9000, thus, providing valuable outcomes for decision makers and academics. Moreover, the results of the study may be generalized in other developed countries whose economy faces similar significant challenges as Greece.

Purpose – Nowadays, small and medium enterprises (SMEs) are incrementally using e-business tools in order to compete in an extremely hostile market and gain global access. The importance of e-business adoption for the economic success and survival of SMEs creates a very interesting field of research. The purpose of this paper is to develop and empirically test a conceptual framework that investigates the factors affecting the e-business adoption decision in SMEs. Design/methodology/approach – The examination of the proposed conceptual framework was made with the use of a newly developed structured questionnaire that was distributed to a group of Greek SMEs. The questionnaire was distributed to 600 companies, while 161 usable questionnaires were finally returned. exploratory factor analysis, confirmatory factor analysis, linear regression methods and the structural equation modelling (SEM) technique were used to test the research hypotheses. Findings – The proposed model explains 71 per cent of the variance of e-business adoption, with firm size, firm scope, IT infrastructure and internet skills being the most important e-business adoption drivers (with firm size being the most significant). On the other hand, CEOs knowledge, adoption cost, and competitive pressure do not seem to play an important role in the e-business adoption decision. Research limitations/implications – A limitation stemming from the implemented methodology is the use of self report scales to measure the constructs of the proposed model. Moreover, the present paper lacks a longitudinal approach, since it is cross-sectional and provides a static picture of e-business adoption. Practical implications – The paper makes an effort in order to point out areas that companies should emphasise in order to successfully adopt e-business and, therefore, harvest its potential benefits. Certain practical implications are offered in the final part of the paper. Originality/value – First, the present study places SMEs in the centre of its attention, while the contemporary research mostly examines the implementation of e-business practices in large organisations. Second, the present study proposes a three-dimensional conceptual framework, including technological, organisational and environmental context. Such a multidimensional approach has randomly been explored in the existing literature. Third, the results of the study may be generalised in other developed countries with similar economic realities and yield interesting outcomes for practitioners in these countries.
