This study aimed to explore the cross-section of digitalization and sustainability in banking and its effect on bank performance. The sample consisted of all of the banks (n = 25) operating in the Republic of Serbia from 2011 to 2020. The research results show that the banks focusing on digitalization and sustainability are profitable, even in the face of coronavirus disease 2019 (COVID-19). Furthermore, using the Pearson’s correlation, the study shows that the level of investment in digital transformation has a strong relationship with the net result. We advocate that digitainability in banking is an important factor in uncertain times and should be fostered and included in bank strategies in the post-COVID 19 world. To the best of our knowledge, this is the first study that provides insight into digitainability and bank performance.

Purpose This study aims to explore the factors moderating possibly indirect relationships between gender diversity and its effect on bank performance. The causality of this relationship remains unclear. Design/methodology/approach The sample consists of all banks (n = 27) operating in Serbia. Findings The gender diversity-performance relationship is indirect. The gender diversity of executive boards positively impacts bank performance, over a threshold level. This is observed only in banks where gender diversity is extended to more than one level of executive authority. Research limitations/implications Gender diversity should be fostered, particularly in small and competitive markets. The gender diversity-performance link is based on gender-related social interactions, which are interdependent and should not be taken into account as isolated factors. Originality/value To the knowledge, this is the first study to provide insight into indirect, gender related, moderatory interactions effecting gender diversity – performance link, in banking.

This study determines the effectiveness of business objectives and key performance indicators (KPIs) of the identified business objectives for different types of enterprise. The evaluations of the relative importance of KPIs are called a fuzzy group‐decision‐making problem. The KPI weights are determined using the fuzzy analytic hierarchical process. The effectiveness of business objectives and KPIs is determined using the adopted Balanced Scorecard Designer Pro. Determination of the KPI rank with respect to each enterprise type is on the basis of Pareto analysis. The priority of management initiatives of the improvement strategy corresponds to the calculated rank, and it has a critical effect on the competitive advantage of any enterprise. The results discuss manufacturing, public and service enterprises, which exist in central Serbia. The proposed approach can also be adapted to different businesses.

The difference between the production cost and selling price of the products may be viewed as a criterion that determines an organization's competitiveness and market success. In such circumstances, it is necessary to impact these criteria in order to maximize this difference. The selling products' price, in modern market conditions, is a category which may not be significantly affected. So organizations have one option, which is the production cost reduction. This is the motive for business organizations and the imperative of each organization. The key parameters that influence the costs of production and therefore influence the competitiveness of organizations are the parameters of production machines and processes used to create products. To define optimal parameter values for production machines and processes that will reduce production costs and increase competitiveness of production organizations, the authors have developed a new mathematical model. The model is based on application of the ABC classification method to classify production line processes based on their costs and an application of a genetic algorithm to find the optimal values of production machine parameters used in these processes. It has been applied in three different modern production line processes; the costs obtained by the model application have been compared with the real production costs.

Digital transformation is the permanent improvement of business processes within a bank by available digital tools and technologies in order to survive in the market. It is driven primarily by the clients' needs, new competitors, regulations, and strategy based on the existing tradition. The aim of the paper is to determine whether there is a link between the money invested in digitalization and the achieved result of the bank through the relevant financial indicators. The results of the research show that the banking offer of alternative distribution channels' products in the Republic of Serbia (RS) follows world trends and it can be considered developed. Furthermore, the level of investment in digitalization has a direct impact on the achieved result of the banking sector. Moreover, the banking sector generates more revenue than traditional products offered, and investments in digitalization, innovation and IT technology are inevitable if they want to survive on the market, which is, due to global trends, the need of clients and requirement of the regulator. It is certainly an imperative for all banks in RS to continue investing in education of employees and clients, improvement of business processes, and new tools in order to survive on the market and be competitive.
