Towards a methodology for the development of integrated IT infrastructures

In this paper, the authors propose and validate a methodology for the development of integrated Information Technology (IT) infrastructures. The motivation for putting forward a new methodology is grounded on the limitations of the various software engineering methodologies (traditional) that exist today. Despite that the traditional methodologies result in the development of Information Systems (IS) from scratch, Enterprise Application Integration (EAI) builds integrated IT infrastructures using existing applications. This significant difference is associated with many issues needed to be realised and addressed like: (a) the changes that such an infrastructure brings to organisations, (b) the resistance to change and (c) the extension of IS lifecycle’s. The proposed methodology consist of eight stages and aims at supporting software engineers, organisations and researchers to build integrated IT infrastructures. As a result the methodology seeks to contribute to the body of knowledge

A Case Study Of E-Supply Chain & Business Process Reengineering Of A Semiconductor Company In Malaysia

Penglibatan e-perniagaan dalam rantaian bekalan telah mewujudkan e-rantaian bekalan yang baru (e-SC) di firma-firma tempatan dan global. Due to globalization and advancement in information technology (IT), companies adopt best practices in e-business and supply chain management to be globally competitive as both are realities and prospects in 21st century

Towards an ontology for process monitoring and mining

Business Process Analysis (BPA) aims at monitoring, diagnosing, simulating and mining enacted processes in order to support the analysis and enhancement of process models. An effective BPA solution must provide the means for analysing existing e-businesses at three levels of abstraction: the Business Level, the Process Level and the IT Level. BPA requires semantic information that spans these layers of abstraction and which should be easily retrieved from audit trails. To cater for this, we describe the Process Mining Ontology and the Events Ontology which aim to support the analysis of enacted processes at different levels of abstraction spanning from fine grain technical details to coarse grain aspects at the Business Level

Reengineering Nonprofit Financial Accountability: Toward a More Reliable Foundation for Regulation

Today, the annual IRS Form 990 tax filing is the principal annual disclosure mechanism of nonprofit organizations. Over time, considerable thought has been put into finding ways to improve access and use of the 990 Form, with only scant attention focused on whether the 990 is the right data source on which to build a system of nonprofit accountability. This paper takes a broader perspective, assessing not only the quality of the financial data and its availability, but also the entire financial reporting model. The paper begins with a framework for thinking about organizational accountability. It then examines the current structure of nonprofit financial reporting and contrasts it with alternative systems developed for publicly traded firms and credit unions. The paper concludes with recommendations for improving nonprofit accountability by reengineering the reporting and oversight systems in the sector.This publication is Hauser Center Working Paper No. 4. The Hauser Center Working Paper Series was launched during the summer of 2000. The Series enables the Hauser Center to share with a broad audience important works-in-progress written by Hauser Center scholars and researchers

Critical Management Issues for Implementing RFID in Supply Chain Management

The benefits of radio frequency identification (RFID) technology in the supply chain are fairly compelling. It has the potential to revolutionise the efficiency, accuracy and security of the supply chain with significant impact on overall profitability. A number of companies are actively involved in testing and adopting this technology. It is estimated that the market for RFID products and services will increase significantly in the next few years. Despite this trend, there are major impediments to RFID adoption in supply chain. While RFID systems have been around for several decades, the technology for supply chain management is still emerging. We describe many of the challenges, setbacks and barriers facing RFID implementations in supply chains, discuss the critical issues for management and offer some suggestions. In the process, we take an in-depth look at cost, technology, standards, privacy and security and business process reengineering related issues surrounding RFID technology in supply chains

A Model-Driven Architecture Approach to the Efficient Identification of Services on Service-oriented Enterprise Architecture

Service-Oriented Enterprise Architecture requires the efficient development of loosely-coupled and interoperable sets of services. Existing design approaches do not always take full advantage of the value and importance of the engineering invested in existing legacy systems. This paper proposes an approach to define the key services from such legacy systems effectively. The approach focuses on identifying these services based on a Model-Driven Architecture approach supported by guidelines over a wide range of possible service types

A nomological network of e-government evaluation

An emergent epistemology has been developing in the field of e-government evaluation as disparate attempts are made in the literature to evaluate and measure different aspects of e-government. To formalize it, this paper proposes a nomological network as an organizing concept for plotting e-government evaluation research. It proposes different forms of evaluation, pre-evaluation, ex-ante, in-itenere, and ex-post as fulfilling different and complementary roles in e-government evaluation. E-Government concepts such as agenda, strategy, processes, and performance are plotted within the nomological network with matching modes of evaluation

Information integration – an essential pillar in e-government development

The purpose of this paper is to explain and promote the need for ERP implementation in the public sector, to support the growing request for effective information systems, from the e-government viewpoint and under its influence. The paper also debates the major challenges in ERP implementation issued from research of published case studies. The challenges analysis turns out four major issues to address in order to overcome the integration obstacles and create a solid infrastructure for e-government.integration, Enterprise Resource Planning (ERP), e-government, public sector, business process reengineering (BPR)

Simulation for business processes and information systems design

Business Process (BP) literature promotes the value of business processes as essential gearwheels that help organizations to reach their goals. Similarly, many process design approaches claim that Information Technology (IT) is a major enabler of business process, a view also shared by the Information Systems (IS) community. Despite this, BP and IS approaches do not provide clear guidance on how to assess the benefits that a given IS design may bring to the BP prior the IS implementation. Nor is clear indication of which modeling techniques could be used to assess such relationship. This paper uses the insights gained during a UK funded research project, namely ASSESS-IT, that aimed to depict the dynamic relationships between BP and IT to propose an alternative framework to develop BP simulation models that depict the dynamic behavior of the relationships between BP and IS
