軟體行業因應政府機關服務導向趨勢採元件化發展方向之研究

軟體服務產業，由於內在條件與外部環境等因素長期以來經營不易，在此經濟前景不明，綠色環保意識抬頭及自由軟體呼聲日益高漲的時代，軟體服務業者是否能以元件化軟體服務，開拓出有別於以往的全新經營模式，是個值得深入研究之方向。 政府機關由於組織性質雷同，服務範圍廣大，應用系統繁多，各系統間常有資料共建共享之需求（如各系統須使用人事資訊系統），也有性質非常相近之服務系統(例如網站資訊服務系統、線上申辦服務系統、行政資訊服務系統或員工入口網)，但對於這些性質雷同之服務系統，是否能經由元件化軟體服務之導入與運用，在保證軟體可靠性、穩定性和系統效能的前提下，如何提高軟體開發效率、縮短開發週期、降低開發成本、提高軟體的可維護性、快速高效地適應需求變化、降低運轉維護成本等，是應用軟體服務廠商競爭力的主要表現，也是導入元件化軟體服務最大的目的。 本研究利用個案分析法，搜集個案內之相關資料進行分析與探討，分別從政府機關組織之特性與提供之服務需求面向，資訊軟體產業面臨之問題等面向進行研究，並運用策略形態分析法的思考程序，進而歸納出元件化軟體服務之解決方案，並就元件化軟體服務的優缺點進行剖析，分析出其整體之成本效益。 期望藉由本研究之結論拋磚引玉，激發起政府機關相關決策長官及資訊軟體服務業者的思維，如何從國家整體產業進步觀點去思考與規劃，快速穩健地導入真正符合民眾期望之資訊服務系統，又能樽節成本，避免不必要之資源重複投入，如此方能促進國家與資訊軟體服務產業之雙贏局面。 關鍵字：元件化軟體、SOA、Web service、軟體服務、經營模式The IT software services industry is facing difficult long-term operating conditions due to internal factors and an external environment beset by economic uncertainty and instability, greater awareness of environmental concerns, and a sharp rise in the growth of independently-developed software. Whether or not the software services industry can use service oriented architecture (SOA) software componentization to create an entirely new business model, is a valuable topic that merits in-depth research. Government institutions, like other organizations, are offering an increasing amount of services and use multiple software applications. These applications usually require shared database and common interface capabilities (e.g. various entities require access to a centralized personnel information system) and similar service structures such as web services, e-application services, online administrative information service systems, and employee portal access. Software componentization is a potential solution for applications requiring well-defined interfaces. With system reliability and stability as prerequisites, the main goals of application service providers and componentization software services developers are the same: to increase software efficiency, shorten development cycles & reduce costs, improve software maintainability, be highly responsive to changes, and flexible and lower maintenance turnaround costs. This research applies case study methodology to collect and group relevant information for analysis and discussion. Topics to be discussed include: software-specific needs of government institutions, issues faced by software developers, the application of strategic posture analysis to compose a set of componentization software services solutions, examination of its advantages and disadvantages, and an overall breakdown of its cost effectiveness. Research conclusions are expected to stimulate further research in future studies and encourage decision-makers in government and the software services industry to consider how the industry can progress to a point where it is stable enough to fulfill the expectations of the public, control costs, and avoid unnecessary resource overlaps, thus promoting a win-win situation for government and the IT software services industry.
