An Empirical Study of Electronic Commerce Intrapreneurship Within the IT Units of Large Organizations

The rapid growth of the electronic commerce (EC) sector saw the traditional business models of many large organizations being challenged by internet technology-based dot.com start-ups. One reason that can be identified for this is the inability of the information technology (IT) units of these large organizations to respond in a timely manner to the technological innovation and entrepreneurial challenge of electronic commerce. There is therefore a need for chief information officers (CIOs) and information systems managers in large organizations to pay greater attention to nurturing electronic commerce ìintrapreneurshipî (also known as corporate entrepreneurship) within their IT units. This study develops and empirically validates a theoretical model for electronic commerce intrapreneurship within the IT units of large organizations through an empirical survey of chief information officers. The survey focuses on measuring the level of EC intrapreneurship within the IT unit as represented by its four theoretical components: new business venturing, innovativeness, self- renewal and proactiveness. The study also investigates other constructs representing the environmental and organizational antecedents of IT unit intrapreneurship, as well as its effects on both electronic commerce assimilation and organizational performance. The results clarify the role that the IT units of large corporations have played in the organizational response to the business and technical innovation challenge of electronic commerce

IS Human Capital: Assessing Gaps to Strengthen Skill and Competency Sourcing

Past research has mainly focused on defining information systems (IS) skills and competencies at the industry or global level; it has offered little guidance on best practices for managing IS at the organization level. And yet, a resource-based view indicates that failure to properly manage skills and competencies could lead to suboptimal outcomes such as a loss of IS process knowledge and innovation, an inability to adequately evaluate vendor performance, and a lack of critical skills and competencies needed to meet future demands. In this paper, we examine how one government agency managed its systems for testing personnel. We describe the need for a process to assess IS skills and competencies in order to analyze the gaps and ensure they are filled. A concrete understanding of existing gaps guides sourcing of skills and competencies through hiring, training, internal transfers, and work allocation. This paper presents an effective methodology for this purpose

EMOTIONAL AND RATIONAL COMPONENTS OF IS SERVICE SATISFACTION AND THEIR IMPACT ON IS SERVICE CONTINUANCE

IS service satisfaction involves assessing both rational and emotional components of the service encounter. Given the extensive prior literature on the rational components of service satisfaction this study explores the mediating role of modal emotions - as the basis for the emotional component of service satisfaction - on IS service continuance. The paper provides a measurement instrument for this purpose and uses it to show the impact of modal emotions on IS service satisfaction measurement. The study tests the emotional and rational components of service satisfaction by way of a survey in a large utilities organization and finds that modal emotions do mediate the influence of the rational component of service satisfaction on an individual’s intention to continue using an IS service

A SOFTWARE TESTING ASSESSMENT TO MANAGE PROJECT TESTABILITY

The demand for testing services is, to a large extend a ?derived demand? influenced directly by the manner in which prior developed activities are undertaken. The early stages of a structured software development life cycle (SDLC) project can often run behind schedule, shrinking the time available for performing adequate testing especially when software release deadlines have to be met. This situation fosters the need to influence pre-testing activities and manage the testing effort efficiently. Our research examines how to measure testability of a SDLC project before testing begins. It builds on the ?design for testability? perspective by introducing a ?manage for testability? perspective. Software testability focuses on whether the activities of the SDLC process are progressing in ways that enable the testing team to find software product defects if they exist. To address this challenge, we develop a software testing assessment. This assessment is designed to provide testing managers with information needed to: (1) influence pre-testing activities in ways that ultimately increase testing efficiency and effectiveness, and (2) plan testing resources to optimize efficient and effective testing. We developed specific software testing assessment measures through interviews with key informants. We present data collected for the measures for large-scale structured software development projects to illustrate the assessment?s usefulness and application

TESTQUAL: Conceptualizing Software Testing as a Service

Software testing has emerged as a distinct responsibility in software development. This paper argues that software testing should be conceptualized as a service rather than being viewed as a sequential line of responsibility in software development. Testing as a service has two key aspects: (1) a service to developers, and (2) a service to end users. This paper draws from the SERVQUAL and software quality literature in information systems to propose a structured measurement tool for testing as a service and to briefly discuss its relationship with software quality. The TESTQUAL framework is described, and its components are defined and exemplified. The practical implications of TESTQUAL are also discussed

An Exploratory Case Study of the Benefits of Business Rules Management Systems

Business rules engines and business rule management systems (BRMS) are gaining popularity especially in large, complex, and real-time business environments. In essence, the business rules approach represents a new paradigm for compartmentalizing the formalization of business policies and rules as a separate component from application code. Given that this phenomenon has not yet been empirically investigated from a research perspective, we report on an exploratory case study undertaken to better understand the impacts of the business rules approach on activities throughout the software development lifecycle at a large Fortune 500 corporation. Our study integrates theoretical notions from the literature on knowledge reuse and systems theory with four constructs – centralization, standardization, externalization and structuration – to categorize the benefits arising from BRMS. Our results suggest that the application of the business rules approach has the potential to facilitate information systems development activities at all stages of the software development lifecycle

Facilitators and Inhibitors for Deploying Business-to-Business E-Commerce Applications: A Multi-Method, Cross-Cultural Study

Firms are increasingly using the Web to conduct inter-organizational business transactions. This type of effort, popularly known as ìbusiness-to-businessî (B2B) electronic commerce (e-commerce) has caught the attention of researchers and practitioners. Although there is a widespread adoption of B2B applications, there is very little empirical research that has attempted to investigate this phenomenon. There is no clear idea on how firms are managing the B2B initiatives and what problems they face in deploying B2B e-commerce systems. This paper describes an on-going research project that examines the facilitators and inhibitors for deploying B2B applications. The project employs both qualitative and quantitative approaches and is being conducted in the United States, Singapore, and Norway. The project is being conducted in two phases. In the first phase, an extensive literature review and iterative interviews with senior IT executives yielded a list of 46 facilitators/inhibitors. In the second phase, a survey instrument was developed based on the initial list. This survey form was pilot tested and sent to senior IT executives in the three countries. The preliminary analysis of data reveals nine categories of factors as affecting the deployment of B2B e-commerce applications in organizations. The current status of the project, preliminary findings from a partial data set, and the studyís potential contributions are discussed

Incidence of Inflammatory Bowel Disease in South Asian and Chinese People: A Population-Based Cohort Study from Ontario, Canada.

BACKGROUND: Inflammatory bowel disease (IBD) is now a global disease with incidence increasing throughout Asia. AIM: To determine the incidence of IBD among South Asians and Chinese people residing in Ontario, Canada's most populous province. METHODS: All incident cases of IBD in children (1994-2015) and adults (1999-2015) were identified from population-based health administrative data. We classified South Asian and Chinese ethnicity using immigration records and surnames. We determined standardized incidence of IBD and adjusted incidence rate ratio (aIRR) in South Asians and Chinese compared to the general population. RESULTS: Among 16,230,638 people living in Ontario, standardized incidence of IBD per 100,000 person-years was 24.7 (95% CI 24.4-25.0), compared with 14.6 (95% CI 13.7-15.5) in 982,472 South Asians and with 5.4 (95% CI 4.8-5.9) in 764,397 Chinese. The risk of IBD in South Asians was comparable to the general population after adjusting for immigrant status and confounders (aIRR 1.03, 95% CI 0.96-1.10). South Asians had a lower risk of Crohn's disease (CD) (aIRR 0.66, 95% CI 0.60-0.77), but a higher risk of ulcerative colitis (UC) (aIRR 1.47, 95% CI 1.34-1.61). Chinese people had much lower rates of IBD (aIRR 0.24, 95% CI 0.20-0.28), CD (aIRR 0.21, 95% CI 0.17-0.26), and UC (aIRR 0.28, 95% CI 0.23-0.25). CONCLUSION: Canadians of South Asian ethnicity had a similarly high risk of developing IBD compared to other Canadians, and a higher risk of developing UC, a finding distinct from the Chinese population. Our findings indicate the importance of genetic and environmental risk factors in people of Asian origin who live in the Western world

An experimental investigation of the use of explanations provided by knowledge-based systems

Ever since MYCIN introduced the idea of computer-based explanations to the artificial intelligence community, it has come to be taken for granted that all knowledge-based systems (KBS) need to provide explanations. While this widely-held belief has led to much research on the generation and implementation of various kinds of explanations, there has however been no theoretical or empirical evidence to suggest that 1) explanations are used by users of KBS, and 2) the use of explanations benefits KBS users in some way. In view of this situation, this study investigates the use of explanations that are provided by a knowledge-based system, from the perspective of understanding both the specific factors that influence it, as well as its effects. The first part of this dissertation proposes a cognitive learning theory based model that both clarifies the reasons as to why KBS need to provide explanations and serves as the basis for conceptualizing the provision of KBS explanations. Using the concepts of the feed forward and feedback operators of cognitive learning it develops strategies for providing KBS explanations and uses them to classify the various types of explanations found in current KBS applications. The roles of feedforward and feedback explanations within the context of the theory of cognitive skill acquisition and a model of expert judgment are also analyzed. These, together with past studies of KBS explanations, suggest that user expertise, the types of explanations provided, and the level of user agreement are significant factors that influence the explanation seeking behavior of users. The dissertation also explores the effects of the use of KBS explanations in judgmental decision making situations supported by a KBS. It identifies and considers four distinct categories of potential effects of the use of explanations --- learning effects, perceived effects, behavioral effects, and effects on judgmental decision making. The second part of the dissertation empirically evaluates the explanation provision strategies in a laboratory experiment in which 80 novice and expert subjects used a KBS for financial analysis to make judgments under conditions of uncertainty. The experiment was designed specifically to investigate the following fundamental research questions: 1) To what extent are the various kinds of explanations used? 2)How does user expertise, the feedforward and feedback provision of explanations, and the level of user agreement influence the amount and the types of explanations that are used? and 3) Does the use of explanations affect the accuracy of judgmental decision-making and user perceptions of usefulness? Some of the major results relating to the determinants of the use of KBS explanations include:1) user expertise is not a determinant of the proportion of explanations used but influences the types of explanations that are used, 2) explanation provision strategy is a critical determinant of the use of KBS explanations with feedback explanations being used significantly more than feedforward explanations, and 3)the three types of explanations are used in different proportions with the Why and How explanations being used significantly more than the Strategic explanations. It was also found that the level of user agreement with the KBS had an "inverted-U" shaped relationship with the use of explanations. The least number of explanations are used when the level of user agreement is either very high or very low. The major results relating to the effects of the use of explanations include the following: 1) the increased use of feedback explanations improves the accuracy of judgmental decision-making but has no effect on user perceptions of usefulness, 2) the increased use of feedforward explanations while having no impact on the accuracy of judgments is positively correlated with user perceptions of usefulness, 3) the use of the Why explanation as feedback improves the accuracy of judgmental decision-making. As well, there was also evidence that the use of the KBS benefited both experts and novices. Considering that an understanding of the determinants and effects of the use of KBS explanations is a critical prerequisite for the design of KBS explanations, these and other findings of the study contribute both towards the development of a theoretical basis for the provision of KBS explanations, as well as the practical design of such explanation facilities.Business, Sauder School ofManagement Information Systems, Division ofGraduat
