This article concerns the newly developed construct—EDC (Employees’ Dynamic Capabilities)—and the mechanism of its influence on the job performance of contemporary employees aiming to contribute to the sustainable development of organizations. EDC seems to be especially important in a modern, dynamically changing work environment, in which obtaining sustainability is not possible without dynamic capabilities, and EDC should be included as the element of organizational dynamic capabilities. The paper aims to define and characterize EDC and then develop a mediation model of EDC influence on job performance, introducing the person–job fit, work motivation, job satisfaction, work engagement and organizational commitment as potential mediators related to sustainable development. The model is empirically verified based on the sample of 550 employees from Poland and USA (research carried out in December 2018) using factors analysis for verification of EDC as a new construct and then regression analysis with mediators for the verification of the proposed model. The results confirmed the role of person–job fit, work motivation, job satisfaction and work engagement as mediators of the analyzed relation, underlining the mechanism of the EDC influence on job performance. The empirical research confirms that EDC influences job performance in a way that is crucial for achieving sustainable development of organizations.

The COVID-19 crisis forced many changes to occur within organizations, which were necessary to keep the continuance of the organization’s operations. Job performance seems to be an important factor determining such continuance, through its influence on the performance of entire organization. Shaping and keeping job performance in times of COVID-19 pandemic was a challenge for organizations, due to its negative impact on employees, causing their stress or lack of sense of security. There is a growing role of HRM specialists in appropriately shaping HRM strategies that can positively shape job-related attitudes, resulting in enhanced job performance during such difficult times. Therefore, this study aims to explain the role of COVID-19 oriented HRM strategies in shaping job performance through job-related attitudes such as work motivation, job satisfaction, and organizational commitment in a time of crisis occurring in the organization due to the COVID-19 pandemic. The study was conducted among 378 organizations operating in Poland during 2^nd wave of COVID-19 pandemic. To verify the hypotheses, descriptive statistics were calculated using IBM SPSS and path analysis was performed using IBM AMOS. The result shows that combined set of "hard" HRM strategies related to the financial aspects and "soft" HRM strategies related to keeping employees’ wellbeing during the crisis gives the best results in shaping job performance through job-related attitudes and consequently strengthening organizational performance. This study contributes to the knowledge concerning the development of COVID-19 oriented HRM strategies, which may also have practical application.

The article concerns the potential influence of employees’ dynamic capabilities on the performance of entire organization, which operates in crisis caused by Black Swan event. It is the expansion of job performance model based on employees’ dynamic capabilities, proposing the possibility of translating the positive influence of those capabilities onto entire organization and underlining the importance of employees’ dynamic capabilities during crisis within organization. Based on literature analysis, the shape of the amended model is proposed, in which employees’ dynamic capabilities influence organizational performance through elements of the original model (person-job fit, work motivation, job satisfaction, work engagement and job performance), and additional ones: person-organization fit, person-supervisor fit. The proposed model is empirically verified based on the sample of 1600 organization operating in Poland, Italy and USA during an active wave of COVID-19 pandemic (which is an example of Black Swan event). The results obtained using path analysis confirmed that employees’ dynamic capabilities indeed influence organizational performance of organizations operating in crisis caused by Black Swan event through elements proposed in the model.

The paper aims to verify the Job Performance Model based on Employees’ Dynamic Capabilities (EDC) and explain the mechanisms shaping job performance based on EDC in an initial phase of the crisis in an organisation due to the Black Swan phenomena, on the example of the COVID-19 pandemic of 2020. Empirical research on Italian organisations affected by the crisis shows that the Model is significantly distorted under such conditions. To verify the internal structure of the Job Performance Model based on EDC under critical conditions, the statistical correlation analysis, linear regression analysis and path analysis were executed using SPSS and SPSS AMOS. The research result of the statistical analysis confirmed that the new version of the Model for organisations under the Black Swan phenomenon was statistically significant without work motivation and job satisfaction. It was also proven that P–J fit still linked EDC and job performance through strengthening work engagement. The research confirmed that the Job Performance Model based on EDC, which has so far been verified under normal working conditions, radically changed its structure during the COVID-19 crisis. This means that factors previously considered important in the Job Performance Model based on EDC have become insignificant in shaping job performance. Therefore, this is an inspiration for further research to verify the Job Performance Model based on EDC in different phases of the crisis.

The notion of information systems (IS) reliability in organization is discussed in this article. It contains critical review of the literature, definition of IS reliability and brief overview of the theoretical model of IS reliability in organization developed by the author (including system reliability, information reliability, service reliability and usage reliability). The potential use of the model of IS reliability is demonstrated as a part of empirical research devoted to the analysis and evaluation of IS by the information technology (IT) specialists from inside and outside of the banking sector. The analysis is based on survey conducted among more than 200 IT specialists from and outside of the banking sector in Wroclaw, Lower Silesia, Poland. Banking sector is given as an example due to its uniqueness—extreme sensitivity to IS reliability and accuracy. The analysis of IS reliability in organization is supplemented by the comparison of the way of understanding the notion by the two groups of specialists in order to verify whether the IS reliability is understood in the same way by industry sectors differing in terms of their sensitivity to IS support.
