| 摘要: | 公司治理在國內已是普遍熟悉的觀念與制度，且已為多數有制度的公司所接受與施行，公司內部的管理完善程度的評量, 愈完善透明管理愈為投資人喜歡, 因而有助於公司股價的提升。而IT治理在國內則是較新的觀念，由於科技投資對公司營運與競爭息息相關，且金額龐大，因此對如何創造優質的管理程序，已越來越成為企業主管所關注的重要議題。如何訂定對資訊科技的採購權與創造效益的責任分層負責結構，以鼓勵並引導企業對IT運用之互動與決策所期望的行為，是本研究所要探討的方向。 本研究將目前新興的IT治理概念的理論與架構作一概括性的整理與報告，說明公司治理與IT治理的關係、IT治理的定義、目標和範圍、IT治理的支援手段與架構模型、IT治理架構與決策模式之關係等，並針對個案銀行做研究分析，探討現今金融產業在資訊科技的運用與管理上所進行的狀況及面臨的議題，從公司治理到IT治理到IT管理各個層面，探討國際標準框架如何協助公司在業務目標達成、風險管理、資源的有效利用等方面落實與控管。 研究結果發現，公司治理乃至於IT治理的良善及透明與否，與公司的股價息息相關，個案銀行因管理制度的透明與效率，IT治理逐漸上軌道，且與國際化接軌，正與近年股價逐步上升與穩定的狀況呈現正向的相關關係。 Information technology is getting increasingly important and has been a key successful factor for most companies. IT governance is a new notion worldwide which originally derived from corporate governance. IT governance simultaneously empowers and controls just like corporate governance does. The motivation of this study is to enhance the understanding of this newly recognized management mechanism, as well as to explore IT governance related issues through a case study of a Taiwan bank. This paper summaries and reports the new IT governance core concepts, which including the definitions, goals, scope of IT governance, and the relationship between corporate and IT governance. The four IT governance supporting models: COBIT (Control Objectives for Information and Related Technology), ITIL (IT Infrastructure Library), ISO/IEC17799, PRINCE2 (Projects In Controlled Environments). The six decision models: Business Monarchy, IT Monarchy, Feudal, Federal, duopoly and Anarchy among five IT governance dimensions: IT Principle, IT Architecture, IT Infrastructure, Business Application Needs, IT Investment and Prioritization. To achieve the research purpose, a large Taiwan based bank was chosen as the case study target company. After implementing a detailed interview, an analysis of the implementation of IT governance in this bank is presented. Lastly, to apply the case study result, we also pinpoint the future directions for this case bank to further improving the performance of IT governance. The contribution of this paper is first to assist managers to recognize and understand IT governance and to provide a real implementation case study for reference. The result is particularly valuable because this case study might be the first of her kind in Taiwan with respect to IT governance. This paper indicates the fineness level and transparency of IT governance affect the confidence of investors. The case bank does benefit from the incorporation of IT governance. There exist a positive relationship between information transparency and management system efficiency. |
