以服務導向架構建構電子化政府之研究－以公司登記與管理資訊系統為例

我國政府自86 年開始推動「電子化/網路化政府中程計畫」以來，一直朝向改進政府行政效率及效能，與提昇民眾的服務品質邁進，最終目的在提供單一整合服務。行政院為整合政府資訊服務資源，推動跨機關創新 e 化服務之目的，開始推動「e 化政府計畫」，並規劃以網路服務 (Web Services) 為基本運作架構之「服務導向架構」 (Service–Oriented Architecture；簡稱SOA)，做為各級電子化政府之建構規範。本論文之研究目的即為以程序理論探討以服務導向架構建構電子政府之過程，並透過情境模擬方式探討服務導向架構在跨機關創新整合服務之應用，經過文獻探討後，選擇適當之程序理論對「公司登記與管理資訊系統」做個案研究，研究結果從「基礎建設面」、「功能面」、「資訊面」及「工作面」四個構面分析發現，導入服務導向架構對個案具有下列優勢：1.分散式運算提高系統效率；2.開放性架構具高度擴展性；3.分層式設計強化資訊安全；4. 設備集中專責管理，確保服務不中斷；5.資源共享、減少資源浪費；6.標準化業務流程；7.系統維運易於管理；8.中央政策配合度高；9.提供更多元化之服務；10.主動式服務，加速資訊流通。而在實務導入過程中發現下列導入服務導向架構之關鍵：1.流程整合之溝通協調能力；2.開發及維運團隊之合作；3.CIO 之權責授權；4.年度預算之編列；5.系統建置與上線之規劃。

Since our government began the movement of Mid-term scheme of e- and network government in year 1997, it was driven to improve government’ efficiency and to enhance the quality of its services with one objective in mind, that was to unify all of services into a single solution. As an effort of unifying government resources and transforming to e-Services in all level of government agencies, the government’s executive branch began to implement “e-Government Proposal” which offering web services as the basic framework Server Oriented Architecture (SOA). as the base service model for all level of agencies in e-Government. The objective of this article is to exercise process theory to discuss the process of reaching SOA e-Government, and to utilize scenario simulation method to discuss how government agencies adapted to this new unify services. After the discussion through varies documentation and articles, and analysis of choosing appropriate process theory for Company Registration and Administration Information System, the results can be divided into four perspectives, they are infra-construction, functional, information perspective and work perspective. After our thorough analysis, we discovered that SOA offered the following advantages in this particular case: 1. Improved efficiency by using client/server computing. 2. High expendability by adopting open source projects. 3. Layered design to strengthen security of data. 4. Centralized hardware management to ensure high reliability of the services. 5. Resources sharing to reduce waste of resources. 6. Standardize the production flow. 7. Easy system maintenance. 8. Better cooperation with centralized decision. 9. Offering more diversify services. 10. Volunteered services to improve the flow the information. In the process of reaching SOA e-Government, we have discovered following key points: 1. Communicating and negotiating to unify process flow. 2. Developing and managing team work. 3. CIO authorization. 4. Managing yearly budget. 5. Developing system and online regulation.
