Evaluating Information Strategic Planning: An Evaluation System and Its Application

Information technology (IT) plays an obviously important role in gaining opportunities and taking the competitiveness advantages, and information strategy planning (ISP) becomes the major concern for the effective implementation of information system (IS) among researchers and practitioners. Most companies have difficulties in developing ISP due to its complexity and diversity. Thus, numerous studies have been done on ISP and the methodology for its effective devising process. However, traditional methodologies do not reflect the rapid change of IT markets and business environments. We identify the critical factor for ISP methodology, and develop the new methodology, so-called information strategy planning methodology (ISPM). Also, based on ISPM an evaluation system of ISP is proposed to enhance the quality and practicality of ISP. The evaluation system is composed of two domains, evaluation of ISP procedure and evaluation of ISP supporting systems. The evaluation system is applied to seventeen major Korean companies' ISPs to reveal its value.

An OWL-based semantic business process monitoring framework

Process monitoring phase is one of the service-oriented business process (SOBP) lifecycle phases. Traditional process monitoring approaches have been only achieved at the syntactic level of the process monitoring contexts, which causes the communication problems such as ambiguous understandings and divergent interpretations. To solve the problems, the process monitoring should be achieved at the semantic level as well as at the syntax level of the process monitoring context. In order to support semantic monitoring operations, an ontology-based monitoring framework for the SOBP execution is suggested in this paper. The suggested framework combines a BPEL4WS process model with the semantic monitoring context which is expressed with OWL.     

A process-oriented methodology for evaluating the impact of IT: A proposal and an application in healthcare

In order to improve the performance of business processes often Information Technologies (ITs) are introduced. However, business processes are known to be complex and distributed among multiple business entities. As a result, the impact of new IT on an entire business process is typically hard to assess as quantitative methods for evaluation are missing. Therefore, in this paper, we propose a process-oriented methodology for evaluating the impact of IT on a business process ahead of its implementation. In our method, process mining and discrete event simulation are key ingredients. Based on automatically stored data, process mining allows for obtaining detailed knowledge on a business process, e.g., it can be discovered how a business process is actually executed. Using discrete event simulation, a model can be built which accurately mimicks the discovered process and which can subsequently be used for exploring and evaluating various redesign of the same process.     

Effects of strategic alignment on IS success: the mediation role of IS investment in Korea

The purpose of this research is to develop a comprehensive information system (IS) evaluation model for IS success linked to organizational performance. The primary focus of this research is to investigate the role of IT investment in business values by means of a group survey of about 300 business executives in Korea. We used the contingency theory to discover the mediation effect of IS investment on strategic alignment and IS success. In contrast to previous research, this study expanded the test scope to IS architecture and organizational structure at the operational level. The results from 273 business executives in Korea indicated that strategy integration with IT is positively related to IT investment, and IT investment is a critical antecedent of IS success. Thus, the implications of the findings are that right-directional IT investment has played an important role in the success of IT companies in Korea.

An iterative mathematical decision model for cloud migration: A cost and security risk approach

This paper presents an iterative mathematical decision model for organizations to evaluate whether to invest in establishing information technology (IT) infrastructure on‐premises or outsourcing IT services on a multicloud environment. This is because a single cloud cannot cover all types of users’ functional/nonfunctional requirements, in addition to several drawbacks such as resource limitation, vendor lock‐in, and prone to failure. On the other hand, multicloud brings several merits such as vendor lock‐in avoidance, system fault tolerance, cost reduction, and better quality of service. The biggest challenge is in selecting an optimal web service composition in the ever increasing multicloud market in which each provider has its own pricing schemes and delivers variation in the service security level. In this regard, we embed a module in the cloud broker to log service downtime and different attacks to measure the security risk. If security tenets, namely, security service level agreement, such as availability, integrity, and confidentiality for mission‐critical applications, are targeted by cybersecurity attacks, it causes disruption in business continuity, leading to financial losses or even business failure. To address this issue, our decision model extends the cost model by using the cost present value concept and the risk model by using the advanced mean failure cost concept, which are derived from the embedded module to quantify cloud competencies. Then, the cloud economic problem is transformed into a bioptimization problem, which minimizes cost and security risks simultaneously. To deal with the combinatorial problem, we extended a genetic algorithm to find a Pareto set of optimal solutions. To reach a concrete result and to illustrate the effectiveness of the decision model, we conducted different scenarios and a small‐to‐medium business IT development for a 5‐year investment as a case study. The result of different implementation shows that multicloud is a promising and reliable solution against IT on‐premises deployment.
