A transaction-oriented architecture for structuring unstructured information in enterprise applications

As 80-85% of all corporate information remains unstructured, outside of the processing scope of enterprise systems, many enterprises rely on Information Systems that cause them to risk transactions that are based on lack of information (errors of omission) or misleading information (errors of commission). To address this concern, the fundamental business concept of monetary transactions is extended to include qualitative business concepts. A Transaction Concept (TC) is accordingly identified that provides a structure for these unstructured but vital aspects of business transactions. Based on REA (Resources, Events, Agents) and modelled using Conceptual Graphs (CGs) and Formal Concept Analysis (FCA), the TC provides businesses with a more balanced view of the transactions they engage in and a means of discovering new transactions that they might have otherwise missed. A simple example is provided that illustrates this integration and reveals a key missing element. This example is supported by reference to a wide range of case studies and application areas that demonstrate the added value of the TC. The TC is then advanced into a Transaction-Oriented Architecture (TOA). The TOA provides the framework by which an enterprise’s business processes are orchestrated according to the TC. TOA thus brings Service-Oriented Architecture (SOA) and the productivity of enterprise applications to the height of the real, transactional world that enterprises actually operate in.</jats:p

The moderating influence of device characteristics and usage on user acceptance of smart mobile devices

This study seeks to develop a comprehensive model of consumer acceptance in the context of Smart Mobile Device (SMDs). This paper proposes an adaptation of the Technology Acceptance Model (TAM) and the Unified Theory of Acceptance and Use of Technology (UTAUT2) model that can be employed to explain and predict the acceptance of SMDs. Also included in the model are a number of external and new moderating variables that can be used to explain user intentions and subsequent usage behaviour. The model holds that Activity-based Usage and Device Characteristics are posited to moderate the impact of the constructs empirically validated in the UTAUT2 model. Through an important cluster of antecedents the proposed model aims to enhance our understanding of consumer motivations for using SMDs and aid efforts to promote the adoption and diffusion of these devices

ERP implementation methodologies and frameworks: a literature review

Enterprise Resource Planning (ERP) implementation is a complex and vibrant process, one that involves a combination of technological and organizational interactions. Often an ERP implementation project is the single largest IT project that an organization has ever launched and requires a mutual fit of system and organization. Also the concept of an ERP implementation supporting business processes across many different departments is not a generic, rigid and uniform concept and depends on variety of factors. As a result, the issues addressing the ERP implementation process have been one of the major concerns in industry. Therefore ERP implementation receives attention from practitioners and scholars and both, business as well as academic literature is abundant and not always very conclusive or coherent. However, research on ERP systems so far has been mainly focused on diffusion, use and impact issues. Less attention has been given to the methods used during the configuration and the implementation of ERP systems, even though they are commonly used in practice, they still remain largely unexplored and undocumented in Information Systems research. So, the academic relevance of this research is the contribution to the existing body of scientific knowledge. An annotated brief literature review is done in order to evaluate the current state of the existing academic literature. The purpose is to present a systematic overview of relevant ERP implementation methodologies and frameworks as a desire for achieving a better taxonomy of ERP implementation methodologies. This paper is useful to researchers who are interested in ERP implementation methodologies and frameworks. Results will serve as an input for a classification of the existing ERP implementation methodologies and frameworks. Also, this paper aims also at the professional ERP community involved in the process of ERP implementation by promoting a better understanding of ERP implementation methodologies and frameworks, its variety and history

Investigating the IT Silo problem: From Strict to Adaptive mirroring between IT Architecture and Organisational Health Services

A crucial problem reducing efficient information flow within healthcare is the presence of siloed IT architectures. Siloed IT Architectures causes disruptive and disconnected information flow within and between health institutions, and complicates the establishment of qualitative health services to practitioners and citizens. In this paper, we analyze this challenge using a mirroring lens. Our research question is, how can we establish a supportive IT architecture that reduces the IT silo problem? Our empirical evidence comes from a case in Norway, where we analyzed a transformation initiative on the national, regional, and local levels. Our investigation into the IT silo problem contributes to the literature on information flow and IT architecture within healthcare in two ways. First, we find that strict mirroring that leads to sub-optimization and silofication, is a major cause for the presence of IT silos. Second, we demonstrate how adaptive mirroring – a modular strategy for combining global and local requirements in IT architecture – improves the changeability and manageability of IT architectures

Semantic discovery and reuse of business process patterns

Patterns currently play an important role in modern information systems (IS) development and their use has mainly been restricted to the design and implementation phases of the development lifecycle. Given the increasing significance of business modelling in IS development, patterns have the potential of providing a viable solution for promoting reusability of recurrent generalized models in the very early stages of development. As a statement of research-in-progress this paper focuses on business process patterns and proposes an initial methodological framework for the discovery and reuse of business process patterns within the IS development lifecycle. The framework borrows ideas from the domain engineering literature and proposes the use of semantics to drive both the discovery of patterns as well as their reuse

INTEGRATING MOBILE IT/CLOUD INTO ENTERPRISE ARCHITECTURE: A COMPARATIVE ANALYSIS

Since the year 2000, Enterprise Architecture has been the object of focus as a method for promoting an IT architecture that establishes consistency between corporate business and IT strategies, and it has been applied mostly in global corporations. On the other hand, with the recent progress in Mobile IT technology and Cloud computing, in the IT systems of global corporations, the shift from conventional on premise server-based IT systems to Cloud computing, such as Software as a Service (SaaS), Hybrid Cloud, and connected Mobile IT systems, has become more pronounced. In promoting Enterprise Architecture, EA based upon an approach compatible to the cutting-edge IT technologies of Mobile IT/Cloud computing will be required by global corporations. This paper elucidates key points for EA methods to respond to the cutting-edge IT technology that will be required in the future by conducting a comparative analysis of the support environments of Mobile IT elements and related Cloud computing technology in each EA framework currently used widely in many global corporations
