Show Me the Green: Three Essays on Information Systems Value and Environmental Performance in Global Organizations.
Businesses utilize information systems (IS) to increase revenues, reduce costs, and spur innovation. IS automate tasks, generate and deliver information, and can transform core value creation processes. As climate change and its associated challenges become increasingly relevant to business enterprises worldwide, IS are a key tool in enabling their response. Prior research shows that IS can either aid or inhibit organizational efforts, yet we do not fully understand their influence in this important context. This dissertation presents three essays examining how IS affects financial market value and greenhouse gas emissions performance in large businesses.
The first essay (Chapter 2) introduces a method utilized in chapter 3. After finding a surprising dearth of international event studies in the IS discipline, a multiple-factor method is selected from related management literature to estimate international financial market reaction. Its performance relative to the commonly-used single-factor model is evaluated with a Monte Carlo analysis. Error correction improvement of the multiple factor model is calculated to be 44%-99% over the single-factor model for conditions observed in world markets 2000-2012.
The second essay (Chapter 3) utilizes the multiple-factor model from chapter 2 to investigate international financial market reaction to Carbon Management Systems (CMS) adoption. CMS, a class of IS, enable the capture and management of carbon footprints. Three main results emerge. First, shareholders do not react positively to CMS announcements, as wealth effects are either not significant or negative, depending on the specification. Second, markets appear to penalize firms in more carbon regulated countries versus others, consistent with theory. Lastly, negative reactions to CMS appear to be dampening over time.
The third essay (Chapter 4) examines the impact of IS on firm GHG emissions for large corporations with a presence in North America. This first-of-its-kind analysis finds interaction effects between GHG reduction plans and the physical deployment scope of ERP modules for Enterprise Support (e.g. HR, Finance, Accounting). Corporations with reduction plans in place and the highest 18% of ES physical scope are associated with reduced CO2 emissions. A one-standard-deviation increase in the ES physical scope deployment measure reduces GHG emissions by 46.63% for these companies.PhDBusiness AdministrationUniversity of Michigan, Horace H.

Exploring The Antecedents Of Successful E-business Implementations Through ERP : A Longitudinal Study of SAP-based Organisations 1999-2003
This research was carried out between 1999 and 2003 on the use of e-business applications in ERP-based organisations. A composite research method based on structured case studies was developed for this study. It combined the application of case methods by Carroll et al. (1998], Klein and Myer (1998), and Eisenhardt (1989). This was used to provide a focused, yet flexible structure, as a dynamic approach to case study interpretive research. The research method used three distinct models at three progressive stages of the study, to provide a multi-faceted view of each case. This composite case-based method was developed to maintain the balance between research rigour and relevance. A pilot case study of nine Australian SAP sites helped ground the theory of the study. This was followed by three stages of study of eleven international cases within a diverse industry context. The method revealed the antecedents of e-business success using the findings from case analyses against three separate research models B2B interaction, e-business change, and virtual organising. A final conceptual framework was developed as new theory of e-business transformation. The theory views e-business transformation as realising the benefits from virtual organising within complex B2B interactions by utilising the facilitators of successful e-business change. The research demonstrates that successful e-business transformation with ERP occurs when value propositions are realised through integration and differentiation of technologies used to support new business models to deliver products and services online. The associated management practice evolves through efficiency from self-service, effectiveness through empowerment towards customer care, and value enhancement from extensive relationship building with multiple alliances. The new theory of e-business transformation identifies the stages of e-business growth and development as a comprehensive plan that should assist managers of ERP-based organisations in migrating their company towards a successful e-business organisation. The detailed analysis of the findings offers a foundational per11pectlve of strategies, tactics and performance objectives for e-ERP implementations. The strength of the theory lies in the synthesis of multiple case analyses using three different lenses over three separate time periods. The triangulation of the three research frameworks provides a method for study at appropriate levels of complexity. It is evolutionary in nature and is content driven. Other researchers are urged to apply similar multi-viewed analysis
An Updated ERP Systems Annotated Bibliography: 2001-2005
The goal of this study is to provide an updated annotated bibliography of ERP publications published in the main IS conferences and journals during the period 2001-2005, categorizing them through an ERP lifecycle based framework that is structured in phases. The first version of this bibliography was published in 2001 (Esteves and Pastor, 2001c). However, so far, we have extended the bibliography with a significant number of new publications in all the categories used in this paper. We also reviewed the categories and some incongruities were eliminated. Furthermore, we present topics for further research in each phase
Enterprise Information Systems Capability and GHG Pollution Emissions Reductions
This paper adds to IT sustainability literature by empirically examining the degree to which enterprise information systems capability impacts organizational greenhouse gas emissions (GHG). We accomplish this by analyzing a unique data set combining surveys of corporate IT, GHG emissions and environmental practices with other secondary sources that contain financial and environmental metrics. We find that high levels of Enterprise Support IS Capability combined with the adoption of firm GHG pollution reduction targets help to reduce firm GHG emissions. On the other hand, the adoption of reduction targets in less IS-capable firms is associated with higher emissions. Our research highlights the role of information technology in firm sustainability programs and the value of information to pollution reduction
Changing Spaces For Social Learning In The Implementation Biography Of An ERP System: A Longitudinal Case Study
This paper describes the dynamics of IT related expertises as social learning distributed in space. The case of an Italian local government organization using an ERP software designed for the public sector has been analyzed. Data on distinctive locational patterns of organizational resources concerning post-implementation enhancements of the system were gathered through interviews and observations of the system in use. Four different locational patterns of IT related expertise have been identified in the case across different time periods: the âimplementation teamâ period (1998-2001), the âera of personalizationâ (2002-2005), the move from the in-house software enhancement to external consultancy (2005-2008) and the more recent appointment of a different consortium of multiple consultants to implement additional software modules

Adaptation to the Needs of Subsidiaries
This study used institutional theory as a lens to understand how far institutional factors affect Accounting Information Systems adoption (integrated in an Enterprise Resource Planning system) and use in a subsidiary. For this purpose and after an extensive review of the literature on the topic an empirical study is done. The research approach is qualitative and a case study research method has been used. The relevant information is collected via semi-structured interviews.
The result indicates that the large majority of daily basis tasks of the company studied depends on AIS (integrated in an Enterprise Resource Planning system) to function. And the fact that it is the Headquarters that chooses AIS/ERP to be used does not have a negative impact on the subsidiary company because the key factors are taken in considerations when selecting and implementing the system
Risk Management for Enterprise Resource Planning System Implementations in Project-Based Firms
Enterprise Resource Planning (ERP) systems have been regarded as one of the most important information technology developments in the past decades. While ERP systems provide the potential to bring substantial benefits, their implementations are characterized with large capital outlay, long duration, and high risks of failure including implementation process failure and system usage failure. As a result, the adoption of ERP systems in project-based firms has been lagged behind lots of companies in many other industries. In order to ensure the success of ERP system implementations in project-based firms, sound risk management is the key.
The overall objective of this research is to identify the risks in ERP system implementations within project-based firms and develop a new approach to analyze these risks and quantitatively assess their impacts on ERP system implementation failure. At first, the research describes ERP systems in conjunction with the nature and working practices of project-based firms and current status and issues related to ERP adoption in such firms, and thus analyzes the causes for their relatively low ERP adoption and states the research problems and objectives. Accordingly, a conceptual research framework is presented, and the procedures and research methods are outlined. Secondly, based on the risk factors regarding generic ERP projects in extant literature, the research comprehensively identifies the risk factors of ERP system implementation within project-based firms. These risk factors are classified into different categories, qualitatively described and analyzed, and used to establish a risk taxonomy. Thirdly, an approach is developed based on fault tree analysis to decompose ERP systems failure and assess the relationships between ERP component failures and system usage failure, both qualitatively and quantitatively. The principles and processes of this approach and related fault tree analysis methods and techniques are presented in the context of ERP projects. Fourthly, certain practical strategies are proposed to manage the risks of ERP system implementations.
The proposed risk assessment approach and management strategies together with the comprehensive list of identified risk factors not only contribute to the body of knowledge of information system risk management, but also can be used as an effective tool by practitioners to actively analyze, assess, and manage the risks of ERP system implementations within project-based firms
Enterprise resource planning systems implementation and upgrade (a Kenyan study)
In recent years there has been an increase in using Enterprise Resource Planning (ERP) systems in large companies and government corporations mainly in developed countries. While there is wide adoption of ERP systems in Western economies, developing countries lag far behind. However, due to recent economic growth, developing countries such as Kenya are increasingly becoming major targets of ERP vendors. There is an urgent need for under- standing ERP implementation issues in developing countries, as ERP systems are still in their early stages in these countries. They face additional challenges related to economic, cultural and basic infrastructure issues. This research investigates the organisational and national context within which ERP is adopted and used in Kenya, and how the context and ERP influence each other. In general, this research is based on the need to study organisations in their societal contexts and information systems in their organisational settings.
The research contributes to the controversial debate on the conflict between standardisation imposed by ERP systems and localisation of business practices. This study provides some key insights into the implementation and use of ERP systems in the public and the private sectors in Kenya. Case study findings suggest that the company sector plays an important role in ERP implementations in several key dimensions. ERP systems with in-built business practices express the tendency toward standardisation. In addition, the study investigates the challenges faced by organisations implementing ERP systems in Kenya and factors influencing ERP upgrade decisions. Findings of this research suggest that ERP implementation and upgrade is influenced by, but not necessarily bound by, existing contextual factors - national and organisational. Two models, namely, the Empirical ERP Implementation Model (EEIM) and the Upgrade Decision Model (UDM), are developed to represent ERP implementation and upgrade practices. The EEIM helps to identify why there will be particularly high variance in potential outcomes and further validates which organisational contexts and ERP implementation configurations create options during ERP implementation and usage. The UDM makes a novel contribution by showing how different forces interact to bring an aggregate of influences to a threshold level where an ERP system upgrade becomes necessary.
The findings of this study also aid the management of organisations that are implementing
ERP systems to gain a better understanding of the likely challenges they may face and to enable them to put in place appropriate measures to mitigate the risk of implementation
failures. This study also proposes an IT strategy framework which can be used by organisations planning to implement ERP to align their business and IT strategy. Finally, the study provides practical guidelines to practitioners on ERP implementation and upgrade based on the experience of the case study organisations and the ERP consultants interviewed
