Managing Risk And Uncertainty In Supply Chains In The Face Of The Current Global Realities, Gurkan Ibrahim Akalin
Managing Risk And Uncertainty In Supply Chains In The Face Of The Current Global Realities, Gurkan Ibrahim Akalin
Information Systems & Operations Management Dissertations
For the last two decades, there has been an increasing academic and practitioner interest in understanding uncertainty and risks, identifying their sources, and managing, reducing and mitigating them in supply chains (SCs). Many sources of risk are already identified and grouped, and some good methods to reduce or cope with them have been described as well. However, literature has not been profound yet. Indeed, certain types of risk sources lack practical definitions and/or effective management techniques (Prater, 2005; Simangunsong et al., 2012). The financial crises of national economies in the late 2000s followed by a global recession (2008-2012) have escalated …
Data Visualization In Exploratory Data Analysis: An Overview Of Methods And Technologies, Yingsen Mao
Data Visualization In Exploratory Data Analysis: An Overview Of Methods And Technologies, Yingsen Mao
Information Systems & Operations Management Theses
Exploratory data analysis (EDA) refers to an iterative process through which analysts constantly ‘ask questions’ and extract knowledge from data. EDA is becoming more and more important for modern data analysis, such as business analytics and business intelligence, as it greatly relaxes the statistical assumption required by its counterpart—confirmation data analysis (CDA), and involves analysts directly in the data mining process. However, exploratory visual analysis, as the central part of EDA, requires heavy data manipulations and tedious visual specifications, which might impede the EDA process if the analyst has no guidelines to follow. In this paper, we present a framework …
Disruption Of Information Technology Projects: The Reactive Decoupling Of Project Management Methodologies, Kurt W. Schmitz
Disruption Of Information Technology Projects: The Reactive Decoupling Of Project Management Methodologies, Kurt W. Schmitz
Information Systems & Operations Management Dissertations
Information Technology projects have migrated toward two dominant Project Management (PM) methodologies. Plan-driven practices provide organizational control through highly structured plans, schedules, and specifications that facilitate oversight by hierarchical bureaucracies. In contrast, agile practices emphasize empowered teams using flexible methods aligned to organizational values reinforced by cultural controls and rituals. While project teams mix and combine practices from both traditions, a stylistic bias remains in the initial project management practices established at the onset of IT projects. A review of existing literature on IT project management serve as a filter on the stylistic biases of these dominant PM paradigms that …
Matching Inventory Replenishment Heuristics To Demand Patterns: A Cost/Benefit Approach, Randall A. Napier
Matching Inventory Replenishment Heuristics To Demand Patterns: A Cost/Benefit Approach, Randall A. Napier
Information Systems & Operations Management Dissertations
Behavioral research indicates that bounded rationality and resource constraints support the use of "fast and frugal heuristics" that intentionally exclude some available information from decision models. Inventory replenishment decisions must be made quickly and efficiently, and as such are a promising realm for the use of fast and frugal heuristics. This research includes a simulation study to identify significant relationships among heuristics and demand patterns, yielding inferences regarding the advantages of selecting replenishment models to match demand patterns. Findings from the simulation are validated against three years of actual usage data for 278 independent demand items from a single industrial …

An Assessment Of User Response To Phishing Attacks: The Effects Of Fear And Self-Confidence, Deanna House
Information Systems & Operations Management Dissertations
Phishing attacks have threatened the security of both home users and organizations in recent years. Individuals of varying levels of computer proficiency are potential targets for a phishing attack; all that is needed is an email address and Internet access. Phishing uses social engineering to fraudulently obtain information that is confidential or sensitive. Individuals are targeted to take action by clicking on a link or providing information. At present, phishing research is lacking in both theory and actual behavioral data. This research aims to fill that gap by introducing a new model and collecting data from multiple sources (including an …
The Competitive Dynamics Of A Firm's Capacity Position And Inventory Leanness Activities: Evidence From Us Manufacturing Industries, Rajat Mishra
Information Systems & Operations Management Dissertations
The notion of `perennial gale of creative destruction' by Schumpeter and Austrian economics has been researched in the field of strategic management to study the competitive dynamics among firms' rivalrous activities. However, its application is sparse in operations management. With the advancement of the field and the increasing pressure on the firms, the strategies regarding operations planning and control are argued to be not just internal according to the conventional norms of operations management, but these strategic moves will be impacted by the moves of their immediate rivals. This competitive imitation is studied in the areas of inventory management and …

Reconceptualizing Technology Use And Information System Success: Developing And Testing A Theoretically Integrated Model, Keng-Jung Yeh
Information Systems & Operations Management Dissertations
Technology Acceptance Model (TAM) research, which pertains to how an information system can be initially adopted by members of an organization, was born two decades ago and grows into one of the pivotal theoretical foundations of the information systems (IS) discipline. However, many IS scholars indicate that recent TAM research fail to break the 20-years-old confinement and provide little intellectual value.To respond to this call for more intellectual depth in TAM research, this dissertation suggests multiple ways to rejuvenate the research stream. First, Bhattacherjee's IS use continuance model (2001), which is based on the Expectation-Disconfirmation Theory, was adopted as the …

The Effect Of Leadership Style On Cio Effectiveness, Kishen Parthasarathy Iyengar
The Effect Of Leadership Style On Cio Effectiveness, Kishen Parthasarathy Iyengar
Information Systems & Operations Management Dissertations
While IS researchers have often opined that leadership is important, a theoretical examination of leadership in the CIO context is lacking. We examine Leadership style in the light of the transformational leadership theory and its impact on organizational level variables such as CIO Role Effectiveness and IT ambidexterity, and individual level variables such as Leader-Member Exchange Relationship and the subordinate's general job satisfaction. Results indicate that contingent rewarding style impacted CIO role effectiveness, which in turn predicted IT ambidexterity. Transformational leadership was the strongest predictor of Leader-Member Exchange relationship, which in turn impacted job satisfaction.

A Two-Order Effect Model Of It Business Value: Theoretical Development And Empirical Test, Vishnu Vinekar
A Two-Order Effect Model Of It Business Value: Theoretical Development And Empirical Test, Vishnu Vinekar
Information Systems & Operations Management Dissertations
A new model for IT Business Value is proposed and empirically validated from longitudinal panel data. We posit that IT has a first-order effect that includes automating, and a second-order effect that is more dependent on informating. Our empirical results demonstrate that IT's contribution to firm performance is mediated via its impacts on productivity, which corresponds to the first-order effect. We further developed and validated a complex but parsimonious moderated-mediation model to show that these paths to business value from IT vary depending on industry information intensity, environmental dynamism, and environmental munificence.

The objective of this research study was to examine factors that promote or discourage knowledge sharing behaviors of knowledge workers in the organizational context. Drawing from multiple streams of research including social psychology, organizational learning, knowledge management, information systems and so forth, this research developed an integrated theoretical model and unveiled three sets …
A Typology Of Cluster Concentrations Based On Factor Conditions Of Production And Evolution Of Supply Chain Infrastructures, Pamela J. Zelbst
A Typology Of Cluster Concentrations Based On Factor Conditions Of Production And Evolution Of Supply Chain Infrastructures, Pamela J. Zelbst
Information Systems & Operations Management Dissertations
If the reader would imagine a 500 piece picture puzzle of which only one single piece is available for research, then it is obvious that any conclusions concerning the puzzle as a whole would at the very best be limited to what the researcher could extrapolate from that single piece of the puzzle. This study contends that to comprehend the puzzle it must be viewed as a whole picture, admittedly comprised of different pieces, but nonetheless only accurately understandable in regard to interaction and interconnectivities when viewed from a macro perspective. Accordingly, concentrations should be viewed from a holistic, macro …
An Empirical Examination Of The Influence Of Information Technology And Trust On Supply Chain Dyad Relationships And Performance, Anil Singh
Information Systems & Operations Management Dissertations
Reacting to increased competition, companies are adopting inter-organizational information systems (IOS) that share information across the supply chain partners. This sharing requires trust. To better understand the phenomenon of trust between partners, we develop an integrated model of trust in supply chains with theoretical underpinnings of transaction cost economics and environmental factors like Information Technology and Power. The framework also takes into consideration; the association between trust and final outcome measures such as performance and satisfaction through supply chain relationship. By assessing the interconnectedness of trust in inter-organizational information systems, with environmental factors, our research model will help researchers as …

Towards A Systemic View Of Organizational Dynamic It Capability: An Empirical Assessment, Anurag Jain
Information Systems & Operations Management Dissertations
In an increasingly complex world characterized by hyper-competition and turbulence, an organization's ability to sustain its competitive advantages depends not only on how it acquires its capabilities, but also on how it orchestrates the relationships among them. While the resource based view of the firm and the literature on dynamic capabilities have provided strategic insights to the successful deployment and expeditious management of scarce resources, there is very little research on dynamic capabilities from an IT perspective. In particular, there is no common understanding of what the phrase "dynamic IT capability" means or how it can be achieved. This study …
