There have been significant advances in the information systems (IS) literature about the business value that can be realized through information technology (IT) investments and the mechanisms through which IT creates different facets of business value. We identify three important gaps in understanding the literature on IT business value. First, it is unclear how risk arising from deficiencies in a firm’s information environment, along with internal and external contextual factors, affects a firm’s IT implementation choices. Second, it is unclear how IT resources in a focal domain need to be combined with knowledge resources in the same domain and IT resources in other domains to develop process capabilities and create process-level benefits. Third, it is unclear what risks IT-enabled process innovations create for different process stakeholders and what controls can be applied to mitigate these risks.
My dissertation addresses the above three gaps in three essays. The first essay examines the influence of a firm’s information risk on its prioritization of accounting enterprise systems (AES) relative to complementary enterprise systems and the moderation of this relationship by the weaknesses of internal controls and environmental uncertainty characteristics. The second essay focuses on the impact of AES implementation on a firm’s internal controls process, and the complementary roles of managerial competence and enterprise systems implemented in other domains related to the internal controls process of the firm. The final essay explores the risk factors that can arise for buyers and suppliers due to the use of reverse auctions, and the controls that can be applied to mitigate the key risk factors. In terms of research methods, the first two essays apply econometric analysis to panel datasets constructed from multiple sources and the third essay uses a combination of Delphi studies and semi-structured interviews.
Collectively, the essays advance our understanding of (1) the factors underlying a firm’s prioritization of IT investment choices; (2) the mechanisms through which IT resources, in combination with human expertise, create business value; and (3) the risks introduced for different stakeholders by the adoption of IT-enabled process innovations and the controls that can be used to effectively mitigate them.
