Accident versus Essence: Investigating the Relationship Among Information Systems Development and Requirements Capabilities and Perceptions of Enterprise Architecture

Description: Information systems (IS) are indelibly linked to the global economy and are indispensable to society and organizations. Despite the decisive function of IS in organizations today, IS development problems continue to plague organizations. The failure to get the system requirements right is considered to be one of the primary, if not the most significant, reasons for this high IS failure rate. Getting requirements right is most notably identified with Frederick Brooks' contention that requirements are the essence of what IT professionals do, all the rest being accidents or risk management. However, enterprise architecture (EA) may also provide the discipline to bridge the gap between effective requirements, organizational objectives, and the actual IS implementations. The intent of this research is to examine the relationship between IS development capabilities and requirements analysis and design capabilities within the context of enterprise architecture. To accomplish this, a survey of IT professionals within the Society for Information Management (SIM) was conducted. Results indicate support for the hypothesized relationship between IS development and requirements capabilities. The hypothesized relationships with the organizational demographics were not supported nor was the hypothesized positive relationship between requirements capabilities and EA perceptions. However, the nature of the relationship of requirements and EA provided important insight into the relationship leading to several explanations as to its meaning and contributions to research and practice. This research contributes to IS development knowledge by providing evidence of the essential role of requirements in IS development capabilities and in IS development maturity. Furthermore, contributions to the nascent field of EA research and practice include key insight into EA maturity, EA implementation success, and the role of IT professionals in EA teams. Moreover, these results provide a template and research plan of action to pursue further EA research in exploring EA maturity models and critical success factors, ...

Organizational factors contributing to an effective information technology intelligence system.

Description: The purpose of this dissertation is to investigate the organizational factors that contribute to effective emerging information technology intelligence processes and products. Emerging information technology is defined as a technology which is little commercialized and is currently adopted by not more than twenty percent of the companies within a given industry. By definition, information technology intelligence is a subdivision of competitive intelligence and business intelligence. I discovered evidence that the information technology intelligence process includes assessment of information technology intelligence needs of consumers, collection of data from internal and external sources, analysis of the collected data and distribution of the analyzed data to the consumers. Exploratory factor analysis confirmed the existence of all the variables in the proposed research model. I found empirical evidence that the final technology intelligence product contributes to better decisions made by consumers, their better environmental scanning, and more funding to information technology departments in organizations from different industries and of different sizes.

Understanding knowledge management and organizational adaptation and the influencing effects of trust and industrial cluster.

Description: Due to rapid environmental change, today's business requires a more collaborative management to ensure positive performance. One of the important means that can help firms adapt successfully to a changing environment is knowledge management. The management of information and knowledge as key to retaining competitive advantage and has recently evolved into a more strategically focused research topic for both business and academic study. Managing knowledge, however, is deemed difficult because many companies recognize the importance of their proprietary knowledge and are not willing to share it freely. Recognizing this weakness, many countries have promoted the development of regional clusters where firms can co-develop their competences and competitive advantage against the world's best competitors by sharing knowledge, resources, and innovative capabilities. Other than industrial clusters, trust is also considered an important factor in knowledge management study. Trust reduces the need to monitor others' behaviors, formalize procedures, and it lowers transaction costs. At the macro level, trust can enhance organizations' core competencies and sustain their competitive advantages through co-evolution. This may occur through the development of group collaborations, cooperative relationships, and networks. The study adopted a field survey research method and used multiple regressions as the data analysis technique. The dependent variable in the study was organizational adaptation, while the independent variables were knowledge management, trust and industrial cluster. Data were collected using survey of key informants from 943 companies. The results of the analysis suggested that knowledge management does have significant influence on organizational adaptation and both industrial cluster and trust impact on organizational learning activities. The major contribution of this study is that it offers a more holistic approach in studying knowledge management by adding a new element: knowledge applying. Moreover, this study offers an initial attempt to test industrial cluster in hopes of advancing the research in management related ...

An Empirical Examination of Service Dominant Logic: The Theory of the Network

Description: Marketing scholars question the ability of the 4Ps to explain higher order phenomena in modern marketing. Scholars contend that marketing's historical framework, based in product centric economic theory, constrains the 4Ps ability to form a foundation for a general theory of marketing. The focus on value embedded in product fails to explain knowledge-based intangible sources of competitive advantage. In response to this concern a new dominant logic for marketing called service-dominant logic (S-D Logic) has been proposed. However, not all scholars are supportive of S-D Logic. Still nescient, S-D Logic lacks a theoretic model, operationalized constructs, and relationships between those constructs. This study addresses those deficiencies by: (1) generation of a grounded theory of a performance-oriented network; (2) empirical assessment of the S-D Logic literature; and (3) development of an inductively generated theory of S-D Logic to include constructs, relationships, outcomes, and hypothesis. This investigation provides an important set of research findings. The resultant service-oriented network theory suggests a theoretic structure for S-D Logic. Use of grounded theory provides a strong empirical foundation based in a leading edge multi-national market segment composed corporations and programs worth hundreds of billions of dollars. The analysis drew upon 44 field interviews and follow-up exchanges. Multiple member checking sessions generated practitioner confirmation of the research conclusions. The work provides actionable theoretical and practical implications. This investigation provides a link between S-D Logic as a foundation for a general theory of marketing and initial model of suggestive of such theory. For the practitioner the service-oriented network model provides actionable constructs. The antecedents identified are largely influencable by inter-firm leadership and provides them a mechanism to tailor the specific service-oriented strategy to support the desired network value propositions.

An empirical investigation of how perceived devaluation and income effects influence consumers' intended utilization of savings from coupon redemption.

Description: Coupons are one of the most popular and attractive tools of promotion. Redeeming coupons makes shoppers feel that they are doing something good for their family's budget, because coupons offer 'savings.' On the other hand, a coupon might have several negative effects on purchase behavior as well, which might 'devalue' the promoted product in the consumer's perception. But a review of the literature shows a lack of attention afforded to the above-mentioned aspects of coupon redemption. In addition, the consumer's coupon redemption behavior is moderated by several factors drawn from research in the fields of market pricing, economics and psychology, each of which have contributed to the current study in their own way. Finally, there does not exist any substantive research as to why coupon redemption rates have been on the decline, despite an increase in distribution of coupons. Therefore, this research not only fills existing gaps in the literature but also enriches it by synthesizing views from different academic disciplines. This dissertation concentrates on grocery products. Data is collected from about 2500 adults, primarily residing in the Dallas-Fort Worth area. The conceptual framework is based on the theory of reasoned action, which suggests that an individual's beliefs influence his/her attitude towards the consequences of actions, and attitudes, in turn, influence the individual's actions. Toward this end, the model incorporates intention to redeem coupons, intention to keep or spend savings and intention of how to spend savings from coupon redemption as the dependent variables, and several other independent variables. Behavioral independent variables are measured using items borrowed from established scales, as well as those developed exclusively for the current study. Standard statistical tools such as factor analysis and accepted measures of reliability and validity (Cronbach's alpha) are applied and reported, while structural equation modeling has been used to re-validate certain ...

Supply Chain Network Evolution: Demand-based Drivers of Interfirm Governance Evolution

Description: Which form of exchange governance performs better in a dynamic environment? This remains an unanswered question in the transaction cost analysis (TCA) and relational exchange literatures. Some researchers purport that transactional governance provides superior performance by providing firms the flexibility to change suppliers. Others suggest that relational governance leads to superior performance because of the willingness of both parties to adapt. Reviews of TCA have turned up ambivalent empirical findings with regard to the effects of uncertainty despite a track record of strong empirical support for other predictions. Because most of TCA and relational exchange theories' predictions enjoy strong support, this research builds upon these theories to propose a theoretical modeling framework for a dynamic environment in a supply chain network (SCN) setting. This dissertation extends TCA and relational exchange to a dynamic, network environment. It uses the approach of building a simulation in order to study in detail the relationship between key exchange factors and the selection of transactional and relational exchange governance over time. This research effort extended TCA theory with a complex adaptive model of supply chain network governance evolution that attempts to link environmental, network, production, firm and exchange factors in a continuously evolving loop. The proposed framework expands transaction cost analysis' explanatory power. Results partially support past scholarly proposal that uncertainty functions as an antecedent of asset specificity rather than as an independent construct affecting governance outcome dependent upon which form of uncertainty is being considered. The successful simulation of supply chain networks as complex adaptive systems shift the focus from deterministic, confirmatory models of exchange to an exploratory, positive model. Instead of exchange governance as an outcome, it is the catalyst of the evolutionary process.

Explaining Buyer Opportunism in Business-to-Business Relationships

Description: The interaction among firms in the supply chain is necessary for business process execution and relationship success. One phenomenon of great significance to buyer-supplier relationships is opportunism. Opportunism is defined as behavior that is self-interest seeking with guile. It is manifested in behaviors such as stealing, cheating, dishonesty, and withholding information. Opportunism negatively impacts relational exchange tenets such as trust, commitment, cooperation, and satisfaction. Furthermore, perceptions of opportunism negatively affect firm performance. In lieu of the known negative effects of opportunistic behavior on buyer-supplier relationships, why do agents continue to engage in opportunistic tactics with their exchange partners? A comprehensive examination is necessary in order to understand why sourcing professionals engage in acts of opportunism. Understanding why opportunism occurs will reveal how to deter it, and this remains a gap in the literature. Based on theories in economics, marketing channels, supply chain management, decision science, and psychology, a comprehensive model tested a set of factors hypothesized to drive the use of opportunistic tactics. Factors include buyer-supplier relationship-specific factors, environmental factors, individual personality-related factors, and situational factors. Data was collected via internet survey of sourcing professionals from private industry and government agencies. Common to many studies of ethics, respondents made choices based on two hypothetical vignettes. Two logistic regression models were used to test the hypotheses. Factors found to affect buyer opportunism included buyer power, corporate ethical values, pressure to perform, leadership opportunism, business sector, honesty/integrity, and subjective expected utility. This research contributes to theory by combining several disparate theories to best explain opportunism. A comprehensive evaluation should determine which theory explains the most variance in decision making. The study contributes to practice by identifying those important factors contributing to a sourcing professional's decision to use opportunistic tactics. The ability to manage these factors should improve the probability of relationship success. ...

Internal Capital Market and Capital Misallocation: Evidence from Corporate Spinoffs

Description: This study investigates the importance of reduced capital misallocation in explaining the gains in corporate spinoffs. The capital misallocation hypothesis asserts that the internal capital market of a diversified firm fails to meet the needs of the relatively low growth divisions for less investment and the needs of the relatively high growth divisions for more investment. Higher differences in growth opportunities imply that more capital is misallocated. This study finds that the higher the difference in growth opportunities of a diversified firm's businesses, the more likely the firm is to conduct a spinoff. This finding supports the argument that diversified firms conduct spinoffs to reduce capital misallocation. This study finds differences in managerial ownership of spinoff firms and of nonspinoff firms. This suggests that the misallocation of internal capital is an agency problem. A low management ownership stake, coupled with the existing differential in growth opportunities between parent and spunoff firms, leads to misallocation of internal capital, thus creating incentives for a spinoff. Spinoffs should result in a shift to the “right" investment policy and to better operating performance for both the parent and spunoff firms. This improvement in operating performance for the post-spinoff firms is expected to be higher when they are from highly different growth opportunity spinoffs. I find mixed evidence regarding market reaction, changes in investment policy, and changes in operating performance. The evidence that supports the capital misallocation hypothesis does not appear uniformly and consistently across the proxies for growth opportunities. However, there is evidence that both parent and spunoff firms benefit from a spinoff. The magnitude of the benefits is larger for spunoff firms than for parent firms. This is as expected because the capital misallocation problem may be reduced, but does not entirely disappear, in the parent firm.

The Home Mortgage Interest Deduction for Federal Income Tax: A Federalist Perspective

Description: The debate over federal income tax treatment of home mortgage interest (HMI) has largely overlooked an important, and possibly unintended political and economic consequence of our federal income tax system. The distribution of the for home mortgage interest deduction tax benefit across states is a possible missing consideration. Specifically, this study offers a federalist1 perspective on the federal income tax benefit from the deduction for HMI - one of the largest personal federal tax expenditures on the books. This dissertation analyzes current national political rhetoric from a federalist perspective. Discussion also includes background, current status, and proposed changes to the tax code for of the HMI deduction. First, a Tobit regression is used to analyze the distribution of the HMI tax benefit across states and to test for disproportionate distribution across states in benefit derived from the federal income tax deduction for home mortgage interest beyond that which is explained by income. This initial part of the study is also the precursor to a hierarchical analysis seeking to identify significant factors affecting the distribution of the benefit of the HMI deduction across states. The Ernst and Young/University of Michigan Individual Model File of 1992 tax returns is the primary data source for this initial part of the investigation. The second part of the analysis examines the effect of sets of factors in a causal hierarchy on the HMI deduction benefit. By first controlling for the effects of personal and identifiable state characteristics on HMI deduction benefit, the possible existence of a residual socio-political force is tested. The primary data sources for this part of the study are the 1990 Census of Population and Housing 5% Public Use Microsample as well as tax data extracted from the Statistics of Income, Individual Public Use Tax File, Level III Sample, as well as ...
