    Modeling is an essential aspect of information systems (IS) development. A modeling method defines the constructs and syntax that modelers can use to develop information models. Despite the proliferation of modeling methods, only a few have been widely accepted by the IS development community. IS developers are ultimately the ones who use these modeling methods and evaluate their acceptability. Therefore, the long-term viability of a modeling method and its eventual success depend on its extensive and continued use by IS developers. This study examines IS developers’ modeling method acceptance by identifying factors that influence their intention to continue using a modeling method. The theory of planned behavior (TPB) is used as the primary theoretical foundation for this research. Based on a comprehensive literature review, a research model to explain IS developers’ modeling method continuance was developed. A cross-sectional survey study was conducted to test the research model

    The software industry is playing a significant role in development of economies all over the world. It is mainly made up of small and medium software enterprises (SMEs). These companies aim to benefit from Software Process Improvements (SPI) to increase product quality and productivity in a competitive environment. Several SPI models and frameworks have been developed to improve software quality in SMEs. As SPI require organizational change and adaptation to new tools, techniques and work practices; organizations have to handle with several challenges emerged from the change. In this study, we present the factors that influence the success and adoption of the SPI models and/or standards used in SMEs. We also present the preliminary findings of the SPI acceptance model that we developed based on an established behavioral theory for SMEs. A pilot survey study was conducted to analyze the model with 20 participants who work in a CMMI Level 3 company.Yazılım endüstrisi tüm dünya ekonomilerinin gelişiminde önemli bir rol oynamaktadır. Bu firmaların çoğunluğu küçük ve orta ölçekli şirketlerden (KOBİ) oluşmaktadır. Bu şirketler, rekabetçi bir ortamda ürün kalitesini ve verimliliğini artırmak için Yazılım Süreç İyileştirmelerinden (YSİ) faydalanmayı amaçlamaktadır. YSİ uygulamaları beraberinde kurumsal değişim ve yeni araçlara, tekniklere ve iş uygulamalarına adapte olmayı gerektirdiğinden; kurumlar değişimden kaynaklanan çeşitli zorluklarla başa çıkmak zorundadır.

    The management and reduction of risk is a central part of product development processes. This paper analyses the extent to which four common product development approaches address risks (waterfall model, stage gate model, design for six sigma, and lean product development). They are analyzed along the four principles of risk-driven design: 1. Identifying and quantifying risks; 2. Making risk-based decisions; 3. Reducing risks; and 4. Creating resilient PD systems. The analysis shows that the existing PD processes only partially address the four principles of risk-driven design and that they have their specific strengths and weaknesses. The paper concludes with a discussion of preliminary empirical findings through interviews and case studies on how to better integrate risk management principles into product development.Massachusetts Institute of Technology.

    Resistant Use of Project Management Methodologies – Using Psychology to Rethink the Influence of Methodology Attributes

    Even though practitioners and researchers generally agree that project management methodologies are very useful in managing IT-related projects, organizations are rarely able to motivate their staff to use them. Even when employees use these methodologies, the question of how they are being used still remains. To better understand the way in which employees use project management methodologies, we develop the construct “resistant use.” Applying a diffusion of innovations perspective, we develop a conceptual model to examine how methodology attributes interact with users psychological needs to influence a user’s resistant use behavior. Based on a sample size of 2645 participants, and using the structural equation modeling technique, we find that a user’s need for achievement and need for cognition moderate the impact of project management methodologies\u27 attributes (relative advantage, complexity, and compatibility) on their resistant usage behavior

    How do Cost-Benefit Evaluations Determine Committed Use of IT Project Management Methodologies –Enriching Our Understanding through Psychology

    Get PDF
    Despite the overwhelming advantages of using an IT management methodology, organizations are rarely able to motivate their staff to use them in a dedicated manner. While empirical research states that the usefulness of a methodology is the single most important determinant of its acceptance and use by actual users, studies have not examined which methodology use outcomes are more important for which type of people in which situations. Our study is a step toward filling the gap in methodology evaluation, development, and adoption literature, which to date has not developed a theoretically and practically complete as well as relevant typology of the costs and benefits of using a methodology and has also not studied the effect of personal traits such as needs. We develop and test a conceptual model, using a pre-test sample of 65 participants, that holds that individual needs determine costs-benefits have a bigger effect on individuals’ committed use of a methodology

    An Integrated Framework of Individual Acceptance of Agile Methodologies

    Get PDF
    Although systems development methodologies (SDM) are believed to help improve the software development process, the deployment of SDMs often encounters developers’ resistance. Agile methodologies, the latest batch of SDMs that are better in dealing with volatile business requirements, are likely to face the same problems since they require developers to drastically change their work habits and acquire new skills. Therefore, it is essential to identify the factors that could potentially influence individual developer’s acceptance of agile methodologies. This paper reviews the literature on the acceptance of SDMs and agile methodologies, which serves to assess current understanding in the acceptance of SDMs and agile methodologies. From this review, we identify a set of potential factors and develop a framework to guide future research in individual acceptance of agile methodologies

    Ubiquitous Healthcare Information System: Toward Crossing the Security Chasm

    Get PDF
    Ubiquitous healthcare information system is increasingly seen as a viable option for reducing the inherent time lag and inaccuracies in the traditional model of healthcare and promoting the delivery and practice of evidence-based healthcare―as and when needed―without any location and time constraints. Although promising, the realization of ubiquitous healthcare information system brings several threats and risks rooted in real-time collection, analysis, storage, transmission, and access of critical medical data. In this research, we address information security concerns pertaining to the paradigm of ubiquitous healthcare information system. To accomplish this we use National Institute for Standards and Technology’s (NIST’s) system development lifecycle model (SDLC) as the underlying framework to explore the current state of ubiquitous healthcare from the perspective of security. We then leverage the model to propose future research directions in this area. By implementing the NIST’s SDLC model in such a manner, we offer a different dynamic of healthcare security that has not been addressed in literature before

    THE INFLUENCE OF USEFULNESS OF AN IT PROJECT MANAGEMENT METHODOLOGY ON ITS ACCEPTANCE AND APPLICATION BY INDIVIDUALS – MODERATING EFFECTS OF NEEDS, GENDER, AND AGE: A NEEDS EXPECTANCY

    Despite the overwhelming advantages of using an IT project management methodology, organizations are rarely able to motivate their staff to use them. While empirical research states that the usefulness of a methodology is the single most important determinant of its acceptance and use by actual users, studies have not examined which aspects of usefulness are more important for which type of people in which situations. Our study is a step toward filling the gap in methodology evaluation, development, and adoption literature, which to date has not developed a theoretically and practically complete as well as relevant typology of the usefulness of a methodology and has also not studied the effect of personal traits such as needs. Based on needs and expectancy theories, we develop a conceptual model that holds that individual needs and contextual factors such as gender and age determine which aspect of the usefulness of a methodology has a bigger effect on individuals’ intentions to actually use the methodology
