Adoption of a New Online Travel Management System for FED-AK

JOURNAL OF CASES ON INFORMATION TECHNOLOGY 2010年第1期12卷 1-16页

作者： Kell, Aundrea Pierre, Shari Hoanca, Bogdan Univ Alaska Anchorage Anchorage AK 99701 USA Univ Alaska Anchorage Management Informat Syst Anchorage AK 99701 USA

This case describes the implementation of an online travel management system at FED-AK, the Alaska office of a U.S. government agency. The previous system was intended to accomplish the same functionality, but due to employee resistance, it was used only as a forms generator in conjunction with a paper- and mail-based process. The new system is integrated, which compels employees to use all the functionality provided. It also incorporates many lessons learned from the old system-in particular, extensive training and online help functions. The system is expected to significantly reduce the cost of travel by minimizing errors, enforcing policies, and reducing transaction costs. The system will also lead to faster reimbursement of employee travel expenses.

Using Analytical Hierarchy process (AHP) to Identify the Relative Importance of the Features Needed for Web-Based systems development

INFORMATION RESOURCES MANAGEMENT JOURNAL 2008年第3期21卷 88-100页

Most of new information systems development is now being undertaken with Web-based architectures. The objective of this study is to identify and assess the relative importance of the required features for methodologies used to develop Web-based information systems. Critical success factors (CSFs) for the development of Web-based applications were identified from the literature and organized into a hierarchy consisting of their dimensions and sub-dimensions. The relative importance of the dimensions was assessed through an analytical hierarchy process (AHP) method based on data obtained in Korea from IT professionals. Information properties and risk control were found to be the two main dimensions. Within information properties dimension, integrity of information was found to be the most important sub-dimension. The relative importance of the features was also found to vary for the three industry sectors investigated. less

Towards Structured Flexibility in Information systems development: Devising a Method for Method Configuration

JOURNAL OF DATABASE MANAGEMENT 2009年第3期20卷 51-75页

Method configuration is a specific type of Method Engineering (ME) that takes an existing organization-wide Information systems development Method (ISDM) as its point of departure. Existing assembly-based ME approaches are not well suited to this task. As an alternative, this article suggests a metamethod approach to tailoring organization-wide ISDMs. We refer to this approach as the Method for Method Configuration (MMC). MMC takes into account the need to combine structure, which is one reason for choosing an organization-wide ISDM in the first place, with flexibility, which is essential for making the chosen ISDM fit actual projects. The metamethod is built using a three-layered reuse model comprising method components, configuration packages, and configuration templates. These concepts are combined efficiently to produce a situational method and thereby to facilitate the work of method engineers. [Article copies are available for purchase from ***]

Information Technology in the Practice of Law Enforcement

JOURNAL OF CASES ON INFORMATION TECHNOLOGY 2005年第1期7卷 71-91页

作者： Williams, Susan Rebstock Aasheim, Cheryl Georgia Southern Univ Coll Informat Technol Dept Informat Syst Statesboro GA 30458 USA Georgia Southern Univ Coll Informat Technol IT Statesboro GA 30458 USA

In February 2001, the Charlotte-Mecklenburg Police Department began the rollout of a "mobile" information system that will eventually enable all information relating to incident reports, arrests, and investigations to be collected, distributed, and managed in a paperless, wireless environment. The system, dubbed Knowledge-Based Community Oriented Policing System (KBCOPS), began as a "grass roots" project within the police department to reduce paperwork, increase data accuracy, share knowledge and information, and promote a problem solving analytical framework. The system has been under development for seven years, from concept to implementation. The strategies and approaches used to develop this system, the technologies employed, and, most importantly, the challenges faced in merging wireless, wired, database, and applications technologies while satisfying the user requirements of the police department are detailed in this report.

User behaving badly: Phenomena and paradoxes from an investigation into information systems misfit

引用

Journal of Organizational and End User Computing 2005年第2期17卷 64-91页

作者： Kanellis, Panagiotis Paul, Ray J. Anthens Univ. of Econ. and Business Greece Brunel University United Kingdom

In its formative years and during the 1990s, 1 Global Energy PLC (GE) went through a series of structural changes precipitated by the deregulation of the electricity industry in the UK. The severity of these changes had a disruptive effect on its enterprise information systems, which were found unable to adapt to the new and constantly emerging organizational realities. GE's experiences illustrate the vulnerability of information systems in turbulent environments, provide for a rich description of the causes of misfit due to contextual change, and establish the ability of a system to flex and adapt as a dependent success variable. In addition, the idiographic details of this interpretive field study raise interesting questions about a number of assumptions we hold regarding the development of information systems and the means by which flexibility can be attained.

Transforming information systems development through computer-aided systems engineering (CASE): lessons from practice

引用

INFORMATION systems JOURNAL 2000年第3期10卷 167-+页

作者： Butler, T Natl Univ Ireland Univ Coll Cork Cork Ireland

In dealing with the challenges posed by the ongoing problem of developing and integrating an evermore complex and diverse range of information systems in a timely manner, practitioners continue to grapple with important issues such as increasing developer productivity and bringing quality improvements to the process and product of systems development. Many organizations have adopted computer-aided systems engineering (CASE) tools with such outcomes in mind. With few exceptions, previous research into the phenomenon of CASE adoption and use has been survey based in the main, and has resulted in some confusion over the benefits to be derived from the use of CASE tools within the systems development process. This paper extends previous work as part of an interpretive, case-based research strategy to examine the adoption and use of integrated CASE (I-CASE) in a single organization. Such an approach facilitates a deeper understanding of the impact that CASE exerts on the process and product of systems development. Based on the experience of practitioners in the organization studied, a set of recommendations is presented. The findings of this study also lend support to the view that an I-CASE development platform does indeed have the potential to exert a positive impact on the development process and its product.

AN INFORMATION-processING FRAMEWORK FOR UNDERSTANDING SUCCESS AND FAILURE OF MIS development METHODOLOGIES

引用

INFORMATION & MANAGEMENT 1988年第5期15卷 263-271页

Various project methodologies have been implemented by organizations seeking to improve systems development performance. These efforts have had mixed success. While some organizations have found that implementation of a systems development methodology leads to on-time, within-budget project completions with improved productivity, others have experienced reduced productivity. To explain this paradox, both systems development and the methodology development are viewed in terms of the 2 key information processes -- uncertainty reduction and equivocality resolution. Project methodologies that are implemented with the procedures, definitions, and policies necessary to reduce the uncertainty and resolve the equivocality associated with the systems development process can be successful if the management of the process allows those mechanisms to be fully utilized. Implementation experiences with a particular methodology in different environments are discussed to demonstrate that equivocality resolution during the implementation process is critical to realizing improved productivity.
