Women in the Australian IT Industry: where are we now? - Graeme Byrne; Lorraine Staehr
The purpose of this paper is to assess the status of women in the IT industry in 2001 relative to their position in 1996 and in comparison to their status in other industry sectors. To achieve this a special tabulation of 2001 and 1996 Australian census data relating to women’s position within the Australian IT industry is analysed. The issues of participation, pay equity and representation at senior management levels are examined. This reveals a fairly negative picture and indicates the need for an intensified effort to rectify the situation. It is shown that women participate in the IT industry...

Rule Mining for Dynamic Databases - A Das; D Bhattacharyya
Association rules identify associations among data items and were introduced in 1993 by Agarwal et al.. Most of the algorithms to find association rules deal with the static databases. There are very few algorithms that deal with dynamic databases. The most classical algorithm to find association rules in dynamic database is Borders algorithm. This paper presents two modified version of the Borders algorithm called Modified Borders. Experimental results show that the modified version performs better than the Borders algorithm in terms of execution time. To address the scalability issue, the paper also proposes a distributed version of the Borders algorithm,...

Don't Leave Patch Management to Chance - Ralph DeFrangesco
Patch management is a costly but necessary part of server management. Should more time be spent on patch evaluation and analysis or testing and implementation? This paper attempts to introduce conditional probability into the patch management process giving the reader a tool to evaluate where best to spend their time, analysis or testing. Bayes’ theorem will be used to help predict the outcome of a patch management example.

A Research Strategy for Investigating Business Process Management Approaches - James Gibson
We are witnessing a revolution in industry which, if successful, will change forever how business systems are developed and the type of staff required. This paradigm shift has only recently become possible as business process conceptual understanding evolved, technologies have matured and higher abstraction levels have become possible. Industry leads Business Processing Systems research as it has the strategic imperative and resources to be effective. Academic research is faced with three challenges: firstly, how to do effective research in an area of such broad scope, secondly, how to make research relevant to practice, thirdly how to spend limited resources effectively....

A Longitudinal Study of ISP Reactions to Australian Internet Content Regulation Laws - Sigi Goode
This paper discusses a longitudinal study which surveys a targeted selection of Australian ISPs to determine both initial and subsequent effects of and attitudes towards the legislation. The paper observes that, initially, ISPs were generally opposed to the legislation, offering stiff opposition to its introduction. The initial results suggested dissatisfaction with the legislation on the part of ISPs, and foreshadowed adverse effects on the online industry. Concerns were also raised that the legislation would not be effective. Two years later, however, ISPs had generally observed little change in operations, arguing that the legislation had had little overall effect. The study...

Executive Information Systems and the Top-Officers' Roles: an exploratory study of user-behaviour model and lessons learnt - Emmanuel Ikart
In recent years a number of organisations have implemented executive information systems (EIS) in order to improve the performance of their executives’ jobs. Although the use of EIS is important in executives’ work, the majority of executives are unwilling to use EIS applications because of their design flaws. By using social factors, habits and facilitation condition variables from Triandis’ framework, this paper extends the Technology Acceptance Model (TAM) to derive useful variables to address the problem of the low usage of EIS by executives. This paper reports on research in progress in Australia on the adoption and usage of EIS...

The Management of Computer Systems in Small Business: a preliminary analysis of the issues of importance to managers - Evan Patullock
Research investigating the relative importance of issues facing organisations in their management of Information Systems (IS) has grown rapidly since the early 1980s. However, this research has largely focused on large businesses, with little comparable data collected in the context of small businesses. This paper reports preliminary results from a pilot project investigating the relative importance of various IS concerns from the perspective of small business managers in the Albury-Wodonga region. Initial results confirm the operational focus of small business managers despite evidence of some concern with more strategic issues. In light of the preliminary nature of these findings, the...

A Credit Union Case Study of the Business Value of IS/IT - Graham Pervan; Hilangwa Maimbo
This paper investigates the business value of IS/IT investments in the Financial Services Sectors (FSS) in Australia using a case study methodology to develop and refine a conceptual model of the relationship between IS/IT investment and organisational performance. The conceptual model has four main components, IS/IT investment, organisational performance, considerations for strategic information systems planning and managerial effectiveness. A case study of a credit union indicates support for components of the conceptual model. Further, the analysis reveals the existence of intermediary factors, operations, product delivery, customer service and staff. It is concluded that directing IS/IT investments to these areas, particularly...

A Model for an Electronic Information Marketplace - Wei Ge; Marcus Rothenberger; Edward Chen
As the information content on the Internet increases, the task of locating desired information and assessing its quality becomes increasingly difficult. This development causes users to be more willing to pay for information that is focused on specific issues, verifiable, and available upon request. Thus, the nature of the Internet opens up the opportunity for information trading. In this context, the Internet cannot only be used to close the transaction, but also to deliver the product - desired information - to the user. Early attempts to implement such business models have fallen short of expectations. In this paper, we discuss...

Securing XML Query Processing Storage - Charles Shoniregun; Oleksandr Logvynovskiy; Kevin Lu
The effective processing of semi-structured data queries is a preliminary part of data mining stage. XML queries employ regular path expressions to find structural patterns within XML documents. The operation of structural join is a crucial part of XML query processing. Existing approaches reduce complex join expressions to several binary structural joins. In this paper, we are proposing a new structural join algorithm called sequence join algorithm, for sequential regular path expressions in securing XML query processing storage. It exploits information about position of the elements in a product to skip generation of the redundant intermediate lists. This paper further...

Creativity, Requirements and Perspectives - Oliver Hoffmann; David Cropley; Arthur Cropley; Lemai Nguyen; Paul Swatman
Is there room for more creativity in information systems? This article grew out of an AWRE’04 panel discussion on creativity in requirements engineering, and the impact of requirements engineering on creativity in systems engineering and systems use. Both panel and article were motivated by the goal of identifying a framework for understanding creativity in a larger context and thus establishing a potential structure for future research. The authors’ research backgrounds differ widely and, at times, our views conflict – occasionally, quite sharply. We make underlying world views - our own and those of relevant disciplines – explicit; identify the paradox...

Issues in IT Service-Oriented Requirements Engineering - Sharman Lichtenstein; Lemai Nguyen; Alexia Hunter
Corporate information technology (IT) management is increasingly service-oriented, offering continuous evaluation and improvement of application, communication, delivery and support services to internal and external customers. Service-oriented requirements engineering (SoRE) plays a significant role in identifying and specifying service requirements, formally defined through service-level agreements (SLAs). However, the new frameworks and approaches emerging to guide these developments have not yet addressed how requirements for such services can be effectively developed, nor identified the diverse issues involved. We report a case study of a web services team development of requirements for an internal Service Desk service. The study revealed five main issues...

Requirements Engineering: a close look at industry needs and a model curricula - Oliver Minor; Jocelyn Armarego
Research endeavours in software development have found that failures and deficiencies of software systems are often rooted in the requirements activities undertaken. One possible cause for poor requirements activities is the appropriateness of the education of those engaged with the requirements component of software development. This education is largely based on model curricula used as guidelines. This paper examines the requirements component of model curricula in the disciplines of computer science, information systems and software engineering. These are compared to the opinions of a small but representative group of practitioners, assembled through personal interviews. The results reveal that the model...

Consensus Making in Requirements Negotiation: the communication perspective - Jenny Price; Jacob Cybulski
When developing an Information System (IS), organizational goals of various stakeholders are commonly in direct conflict. Furthermore, individuals often rank their private objectives well over their management's directions. Recognising and reconciling all these diverse goals, and reaching agreement among the stakeholders, are prerequisite to establishing project cooperation and collaboration. This paper focuses, in particular, on the negotiation and consensus making during requirements elicitation - the earliest stages of the IS development process. As requirements elicitation involves rich communication between project stakeholders, we therefore explore negotiation and consensus making from the communication perspective. The resulting model assists our understanding of the...

Requirements Engineering and Software Project Success: an industrial survey in Australia and the U.S - June Verner; Karl Cox; Steven Bleistein; Narciso Cerpa
Because requirements engineering is recognized as critical to successful software projects we surveyed a number of software practitioners regarding their software development practices during recent software projects. Relationships between requirements practices and software project outcomes enable us to better understand requirements issues and their relationship with project success. We asked three sets of questions directly related to requirements issues: 1) requirements practices, 2) the sponsor and customers/users, and 3) project management. Our respondents were from business organizations in the U.S. and Australia, and were almost exclusively involved in in-house software development. The most significant factors from each question set were:...

The Virtual Shopping Experience: using virtual presence to motivate online shopping - Carolyn Chin; Paula Swatman; Paula Swatman
Online shopping has thus far tended to be a niche business – highly successful in selling digital products such as shares, software and, increasingly, music and films, it has been less successful in persuading the purchasers of ‘traditional’ goods such as cars, clothes, toiletries, or household appliances to forsake their physical retailers and move into cyberspace. In this wide-ranging review paper we investigate the issue of the virtual experience – endeavouring to understand what is needed for a successful ‘shopping experience’ online and what the possible obstacles or pitfalls along the way might be. We initially introduce the concepts of...

The Relevance of Value Net Integrator and Shared Infrastructure Business Models in Managing Chronic Conditions - Susan Lambert
There is widespread support for chronic condition management (CCM) programs that require a multi-disciplinary, care-team approach. Implementation of such programs represents a paradigm shift in primary care service delivery and has significant resource implications for the general practice. Integral to the widespread uptake of care-team based CCM is information collection, storage and dissemination amongst the care-team members. This paper looks to ebusiness models for assistance in understanding the requirements of general practitioners (GPs) in providing multi-disciplinary team care to patients with chronic conditions. The role required of GPs in chronic condition management is compared to that of a value net...

A PDA based Point of Care E-Health Solution for Ambulatory Care - Daniel Walsh; Carole Alcock; Lois Burgess; Joan Cooper
The adoption of PDAs and mobile communication is expected to provide a solution to the use of computer technology by healthcare workers at the point-of-care. The Australian National Health Information Strategy, Health Online, is providing national leadership for approaches to address the quality and availability of information to assist in the planning and delivery of care. One area for potential growth is the availability and capture of information at the point of care by healthcare providers. A key factor in the lack of adoption of systems, is that traditionally health care information systems have been designed for desktop computing whereas...

A Capabilities Analysis of E-Fulfilment Businesses: transformation in the logistics industry - Janice Burn; Paul Alexander
This paper reports on the evaluation of practices of 48 leading e-fulfillment suppliers in the UK. Initial findings suggest that while a comprehensive model of e-fulfilment is validated these organisations are also providing services not previously recognised as e-fulfilment capabilities by the literature. This leads to the development of a staged model of transformation, which implies that the industry will embrace radical change in some sectors and lead to a new definition of e-fulfillment businesses. More in depth investigation leads to a proposed definition, and a methodology to measure the degree of transformation.

Diffusion of Innovation - The Adoption of Electronic Commerce by Small and Medium Enterprises (SMES)- A Comparative Analysis - Wayne Pease; Michelle Rowe
This paper explores the issues that influence the diffusion of innovation as it relates to the adoption of e-commerce by Small and Medium Enterprises (SMEs). It seeks to identify factors facilitating and inhibiting such adoption across contexts – regional, small city and large city. This analysis is cross cultural so the impact of differing economic and cultural issues also will be identified in this research. Whilst it is generally accepted that the strategic use of information technology (IT) is vital in the marketplace, the rate of such uptake between small and large businesses varies. This research seeks to identify the...
