我國壽險產業在產品、獲利、通路、法令及未來發展方向等各方面的改變，造成各壽險公司必須在經營策略上有所改變。而基於資訊系統對企業影響演進的歷程與策略協同模式的觀點，當代企業，資訊技術已扮演著舉足輕重的角色，從降低成本與提升效率到企業再造與典範移轉。雖然資訊系統是協助組織面對環境改變與企業經營的基礎，也是在知識經濟下以知識為基礎的新產品與服務的基石，但是若企業的策略無法與IT的策略緊密的結合，資訊技術就無法發揮其應有的功效。 老舊系統在面對包括驟變的產業模式、驟變的商業模式、新興的資訊技術與新的資訊技術架構等多面向的衝擊，實在無法協助企業，達到敏捷性企業的境界，因此必需要考慮資訊系統的轉換。然而，老舊系統的轉換卻又是費時、耗錢且冗長的工作，同時，很多企業的系統轉換，並不是一次完成，而是靠一連串的系統改善或再造專案來完成，就更容易造成前後不一致的狀況，而無法達成預期的目標，因此，在進行資訊系統轉換之時，必須要擬定老舊系統轉換策略，才能夠整合各自獨立的專案，朝向一致的目標邁進。 / Life insurance industry of our country is in the changes of various fields such as products, profits, distribution channels, regulations and future thrusts. Lots of insurance companies have to change their strategy. As we knew information technology has been playing very important roles, for example, IT can provide critical revenue opportunities and cost savings during tough times and IT has become both an enabling element and driving force within this rapidly shifting industry, but base on the theory of business IT alignment, if IT strategy could not align with business strategy then it could not work as efficiency as we expected. The need for agility is commonplace across every industry. Could the legacy systems support this kind of change? Unfortunately, most legacy systems prevent businesses from being more adaptable to change. The only way is transforming legacy architectures into reliable, adaptable assets that contribute to ability of an enterprise to respond to continuous, fast-paces change. But transforming the legacy system is time-consuming, expensive and tediously long work, we have to set up legacy systems transformation strategy to ensue successful.
