Much research regarding IT investment emphasizes the financial and operational of decision-making, there has been relatively little research concerning how contextual factors influence the IT investment decision-making process. In attempt to address this research gap, this study employs a contextualist approach to investigate how an educational institution does in practice when making IT investment decisions.esearch findings suggest that the nature of decision-making in an IT investment can be described as an interpretation by project teams. Furthermore, the study revealed the influence of an IT champion and the force of an IT culture during the IT decision-making process.he theoretical contribution arises from extending contextualist approach to the field of decision-making on IT investment. The practical contribution lies in illustrating the importance of IT champions and IT culture in the decision-making. Empirically, this study has significant value for MIS researchers by highlighting the contextual issues that affect the decision-making on IT investments.APPROVAL FOR SUCCESSFUL DEFENSE ICKNOWLEDGEMENT VBSTRACT VIIONTENTS XIIST OF TABLES XVIST OF FIGURES XVIIHAPTER ONE: INTRODUCTION 1.1 Motivation and Scope of the Study 3.2 Definition of IT Investment 6.3 The Significance of Decision-Making on IT Investment 8.4 Research of Decision-Making on IT Investment 12.5 Objective of the Study 15.6 Overview of the Research Design 16.7 Organization of the Study 18HAPTER TWO: LITERATURE REVIEW 20.1 Rational Perspective 21.1.1 Capital Investment Analysis Techniques (CIAT) Approach 21.1.2 Multi-Criteria Decision Analysis (MCDA) Approach 23.1.3 Balanced Scorecard (BSC) Approach 30.1.4 Real Options Analysis Approach 32.1.5 Instinct Approach 34.1.6 A Brief Summary of Rational Perspective 35.2 Non-Rational Perspective 36.2.1 Act of Faith Approach 37.2.2 Contextual Approach 38.2.3 A Brief Summary of the Non-Rational Perspective 42.3 Limitations of the Rational Perspective 43.3.1 Difficulty in Identifying Costs and Benefits 44.3.2 Neglect in Interpreting Context 45.4 Research Questions 46.5 Summary 49HAPTER THREE: THEORETICAL FRAMEWORK 51.1 Concept of a Contextualist Framework 52.1.1 Context 54.1.2 Content 55.1.3 Process 56.2 Applications of Contextualist Frameworks in MIS 57.2.1 Information Technology Strategy 58.2.2 Evaluation of Information Technology 59.2.3 Implementation of Information Technology 64.2.4 Security Policy of Information Technology 65.3 Synthesized Conceptual Framework 67.4 Summary 69HAPTER FOUR: RESEARCH METHODOLOGY 71.1 Positivist vs. Interpretive Research in Information Systems 72.1.1 The Positivist Approach 73.1.2 The Interpretive Approach 74.1.3 The Choice of Interpretive Approach 76.2 Research Strategy 79.2.1 Case Studies 81.2.2 Research Design 84.3 Summary 91HAPTER FIVE: CASE STUDY 93.1 Case Study Background 94.1.1 The Background of CAMELOT 94.1.2 A History of IT Investment at CAMELOT 98.1.3 Delivery of Integrated Service Systems (ISS) Project 102.2 Case Study: ISS Project 105.2.1 Subproject One: Learning Service Management System (LSMS) 106.2.2 Subproject Two: Membership Management System (MMS) 109.2.3 Subproject Three: Virtual Community Management Systems (VCMS) 114.2.4 Themes from the Case Study 116.3 Summary 121HAPTER SIX: DISCUSSION 123.1 The Nature of the IT Investment Decision-Making Process 124.1.1 A Response to the Nature of the Educational Sector 125.1.2 An Effect of Successful Experience in Development of IT Projects 126.1.3 An Advocacy of IT Champions 128.2 The Force of an IT Culture 132.3 Summary 137HAPTER SEVEN: CONCLUSION 139.1 Overview of the Dissertation 140.2 Research Contributions 143.2.1 Theoretical Contribution 144.2.2 Practical Contribution 145.3 Limitations of the Study 145.3.1 Research Approach Limitations 146.3.2 Research Method Limitations 147.4 Suggestions for Further Research 148.5 Summary 149IBLIOGRAPHY 151PPENDIX A: INTERVEW PROTOCOL 167application/pdf1335971 bytesapplication/pdfen-US資訊科技投資資訊科技決策決策過程情境架構詮釋性研究個案研究Information Technology InvestmentIT DecisionsDecision-making ProcessContextualist ApproachInterpretive Approach, Case Studyhttp://ntur.lib.ntu.edu.tw/bitstream/246246/180030/1/ntu-98-F86722053-1.pdf
