Dynamic enterprise

Abstract: Nowadays, enterprises can gain and sustain a competitive advantage in hypercompetitive environments for only a limited period of time. In order to be able to do that, enterprises must be dynamic. Even though – several authors suggest a positive association between organisational culture and the enterprise’s dynamic – we are still lacking the empirical support for such assertion. Therefore, we empirically tested the association between the type and strength of culture and the level of enterprises’ dynamics. Since organisational culture and the enterprises’ dynamics are both a complex phenomenon, we applied a case study approach combined with quantitative methods. The research indicates that the adhocracy culture type positively influences the level of enterprises’ dynamics. Regarding the strength of culture, our research results show that positive effects of strong culture exceed the eventual negative effects of such culture and positively influence the level of enterprises’ dynamics.

Abstract: The notion of enterprise architecture (EA) and EA-based capabilities in IS literature has emerged as an important research domain. However, the conceptualizations of EA-based capabilities remain ambiguous, largely not validated and still lack a firm base in theory. This study, therefore, aims to rigorously conceptualize EA-based capabilities grounded in theory and puts forward the notion of dynamic enterprise architecture capabilities. These capabilities highlight the core areas in which organizations should infuse EA. The purpose of this study is to develop a reliable and valid measurement scale. This scale is validated using item-sorting analyses, expert reviews and an empirical study of 299 CIOs and enterprise architects. The outcomes support the validity and reliability of the scale. The dynamic enterprise architecture capabilities scale developed in this research contributes to theory development and the EA knowledge base. The scale may be used as an assessment or benchmarking tool in practice.

Abstract: With a bandwidth reservation mechanism, we propose that LTE can assist existing WiFi networks to improve the Quality of Experience (QoE) of wireless communication in enterprise and meanwhile increase the available spectrum. To address the associated network selection problem between WiFi and LTE, in this paper based on the 3GPP standard Access Network Discovery and Selection Function (ANDSF) framework, a context-aware solution named Extended Dynamic Enterprise ANDSF (EDE-ANDSF) is presented. It can select interfaces according to real time network conditions and cater for specific enterprise requirements.

Abstract: Dynamic enterprise risk management (ERM) entails holistic decision-making for critical corporate functions such as capital budgeting and risk management. The interplay across business divisions, however, is complicated due to their natural interactions through the shared and dependent risk exposures within an intricate corporate structure. This paper develops an integrated optimization framework via a copula-based decision tree interface to facilitate ERM decision making to meet the specified enterprise goal in a multi-period setting. We illustrate our model and provide managerial insights with a case study for a financial services company engaged in both banking and insurance businesses.
