資訊系統整合業經營策略之個案研究

賴志明 Unknown Date (has links)
國内資訊系統整合服務業之廠商大大小小數百家,由於高度競爭的結果,資訊業的購併與因經營不善而退出市場的狀況不斷發生,其競爭之激烈與無情可見一般。面對今日的產業環境,如何擬定策略、永續經營,是資訊系統整合服務廠商所面臨的一大課題。本論文以個案公司為例,對於資訊系統整合服務廠商面對目前日趨複雜的市場環境與競爭壓力,試圖找出該產業的關鍵成功因素,並思考該如何建立本身企業的核心能力,於眾多競爭廠商中脫頴而出。 經由對國內產業環境變化相關資料之分析,與系統整合相關廠商現狀的了解,選擇以個案公司為例,以訪談方式收集個案公司相關資料分析、研究,探討個案公司面對產業環境變化之因應策略與具體作法,並提出研究結論與建議,以供個案公司對於未來經營規劃與運作之參考。 本研究之架構,採用Aaker的理論架構來進行內外在分析;分析在於外在環境中的機會與威脅,以及該產業關鍵成功因素,並了解個案公司所具備之優劣勢。接著做策略制定與評估;擬定個案公司未來的可行策略方向,發展根本策略,再於根本策略之下發展營運策略。最後是策略執行與行動計畫;根據選擇的營運策略方案,擬定出個案公司功能性政策,由相關單位落實執行。 透過Porter五項競爭力的分析,瞭解產業環境中的競爭態勢,認清楚企業目前所身處的競爭環境,並找出產業中競爭的關鍵因素。透過司徒達賢之策略架構,說明個案公司之經營策略。配合從關鍵成功因素與外在環境分析得出的後向推論,將有助於我們修正目前的策略,制訂出適合個案公司在面對未來變化可因應的較佳策略。 本研究除了對個案公司的經營策略,提出相關的建議以外,並且詳細闡述策略的型態以及對應之功能性政策。對於個案公司與其他同業,以及對本產業有研究興趣的學者,希望有所助益。

以XML框架發展開放性財務報表之系統模型

劉展嘉 Unknown Date (has links)
網際網路的快速成長不僅改變了企業的經營、管理模式,也改變了企業間的溝通方式。早期的EDI由於高成本與封閉性,構築起極高的進入障礙。1998年2月,美國W3C組織正式公佈XML的Recommendation 1.0版語法標準。XML搭配起網際網路的開放性,提供各專業機構、不同產業界、學術界和特定應用領域發展各自標準的文件和訊息,以利資訊的交換、處理和相關衍生性資料加值服務。   因此,本研究期望能根據財務報告的格式制定出一個以XML為基礎的文件結構(Schema),並提出一個中介(Middleware)系統模型,以轉換企業資訊系統內之財務資訊為XML-Based的財務報告。

網路服務環境用戶端理財代理人系統之研究

黃文杰 Unknown Date (has links)
摘要 財政部於民國90年11月通過金融控股公司法,此法鼓勵了金融相關產業(證券、銀行、保險、基金等業務)朝向業務整合,擴張金融版圖方向努力。如此大規模的金融經營型態調整,不僅是金融體機構的整併,尚得藉由資訊系統的整合以發揮其最大效用。隨著網路人口的增加,Charles Schwab由網路下單服務所獲得的利益,日漸吸引金融業者的網路金融投資。在經濟衰退、失業率漸增、微利率的時代,民眾在理財上也就逐漸投注更多心力。 有鑒於以上的發展,本研究乃著手收集相關文獻,整理分析相關知識作為研究基礎,利用具跨平台特性Java為開發工具且以銀行公會制定之交易訊息格式標準做為溝通的基礎,選擇以Web Service SOA作為系統模型,提出本研究的雛型架構,並實作雛型系統以驗證此架構的可行性。 綜合本研究最大成果在於:(1)參考實際金融理財服務需求,建構鬆散性結構的金融服務。(2)透過具延展性、獨立性及可移植性平台做異質性的資訊系統整合。(3)提供用戶自行設定或是組合客製化服務,協助用戶輕鬆理財。 為求本研究能發揮最大的貢獻,期望以下議題能有合適解決方案:(1)線上網路交易的付款機制能獲得網路大眾最大的信任。(2)金融產業結盟,以提供使用者最多選擇及理財整合。(3)政府長久規劃以整合現有金融資源,提升整體產業競爭力,邁向國際化。 關鍵字:XML、Web Service、SOA、資訊系統整合、金融控股、理財 / Abstract The Ministry of finance enacted the Financial Holding Company Act in November 2001. The law encourages relevant financial industries, such as securities, banks, insurance, funds, and so on, in order to integrate business and expand financial territories. Such large-scale adjustment of financial management patterns indicates the incorporation of financial institutions, and it effectively develops itself to the most through the integration of information systems. With the increase of Internet population, Charles Schwab gradually attracts the financial investment on the Internet as a result of the benefits gained from the Internet service. In the era of economic recession, high unemployment rates and low interest rates, the public gradually put in more efforts in managing finances. As a result of the above-mentioned development, this research aims to collect relevant literature, and to analyze relevant background knowledge as the research foundation. The trans-platform Java will be adopted as the development tool, and the Message Format Specification of the business transactions established by the Association of Banks will be regarded as the foundation of communication. Moreover, Web Service SOA will be chosen as the system model, and the miniature structure of this research will be proposed. Finally, the miniature system will be practically established in order to test and verify the feasibility of this structure. The largest outcome of this research lies in: (1) the consultation of the service requirement in practical financial management in order to construct the financial service with loose structures, (2) the establishment of heterogeneity in the integration of information systems though the expanded, independent, and transplantable platform, and (3) the supply of the service on subscribers’ self-setup or the combination with customization in order to assist them in managing finances easily. In order to make the most contribution out of this research, it is hoped that the following issues can have appropriate solutions: (1) the payment mechanism in on-line business transactions can gain the public’s trust and confidence, (2) financial industries can form an alliance to provide users with the most choices and integration of financial management, and (3) the government plans to integrate the available financial resources for a long time to promote the competitiveness of the overall industries toward internationalization.

透過ODS進行企業資訊系統整合之研究-以某企業為例 / Using ODS to integrate enterprise systems: A case study

黃琬婷, Huang,wan ting Unknown Date (has links)
由於科技快速進步,企業經營也隨著科技的進步而產生重大變化,不但需求變化快速,企業還要即時快速反應外在環境,於是企業對於資訊系統整合的議題越來越重視,希望將功能導向的系統轉變為流程導向的系統,將資訊有效的整合及標準化,讓企業能快速地與外在環境連結,進而提升整體營運績效。 整合的方法非常的多,大致上可分為四類。目前對於哪一種整合方法是最有效率、效益也無一定論。最主要的原因是不同的整合個案會有不同的整合需求,若只從理論方面來探討資訊系統整合所帶來的效用並無法具體地呈現其價值。 有鑑於此,本研究之目的是希望透過個案單位的作業模型,分析、建構出整合的資料模型。因此,本研究以階段性的方法設計資料整合模型及其運作方法。在第一、二階段當中,先針對個案單位的流程進行系統資料流程塑模及業務流程塑模,再從業務面及系統面找出資訊中斷的地方及因素,並將問題具體地描述出來。在第三階段中,本研究挑選了最適合此個案單位的整合方法,也就是使用資料層級(Data-Level)整合的方法,設計整合的資料模型將資訊流完整的串接起來以支援企業的決策需求。最後一階段則要利用ETL說明整合的系統運作模式,並說明此個案單位使用ETL時,可能會遇到的問題及初步的解決方法。 / Owing to rapid advances in technology, enterprises have a major change of the progress of science and technology. The enterprises not only change rapidly in demand, but also have to response to the external environment rapidly. Hence, enterprise information system integration issues get more attentions. Enterprises hope to improve their systems from function-oriented to process-oriented because the effective integration of information and standardization allows enterprises to quickly link with the external environment and to enhance the overall operating performance. However, there are many kinds of integrated approaches. At present, there is no substantive conclusion in approaches to integrate efficiently all systems in business. The main reason is that the integration of different cases has different integration requirements. Therefore, it cannot concretely show the value of system integration through the discussion of the theoretical aspects. In this thesis, this study aims to enhance the operation of a case to model, analyze, and construct an integrated data model. This research has 4 phases to construct integrated data model. In phase 1 and 2, this study builds the case data flow modeling and business process modeling and discovers information gap. In phase 3, the study selects the most suitable method for this case, that is, to use the data level integrated approach to design integrated data model. Finally, using ETL illustrates system operation mode and describes the case which may encounter problems and initial solutions follow in phase 4.
