利用軟體維護生命週期及管理活動探討資訊系統軟體維護特性
ANALYZING CHARACTERISTICS OF INFORMATION SYETEMS MAINTENANCE BASED ON SOFTWARE MAINTENANCE LIFECYCLE MODEL AND MAINTENANCE ACTIVES
摘要
企業投入大量資源且千辛萬苦完成了資訊系統，勢必寄予高度的厚望，更希望 能為組織帶來更高的效益。因此，如何有效延長資訊系統運作的生命期成為必 然的趨勢，也是軟體維護作業的一項重要課題(賴森堂, 2001)。而軟體維護過程 可視為軟體生命的另一個循環，軟體系統能否持續展延以增長其生命期，與維 護階段的相關作業有非常密切的關係。透過對國內企業進行問卷調查及問卷統 計分析，瞭解企業內各資訊系統在維護生命週期中，各個階段的系統維護活動 的特性，提出相關的建議，提供給管理者做為改善軟體維護工作的參考，相信 將有助於企業了解維護管理活動所帶來的特性，協助企業以維護活動產生的企 業效益重要性來安排維護工作、選擇適當的更新版本，以及最後降低系統的維 護成本。

The enterprises have invested a large number of resources and undergone all conceivable hardships to accomplish the information system that they undoubtedly place high expectation on and also hope for bring better benefits to their organizations, so it has inevitably become a tendency to study how to effectively prolong the lifetime of the information system’s running and one important subject for software maintenance operation as well ( Lai Sentang, 2001). The process of software maintenance could be regarded as another cycle of the software’s life. Whether the information system could be continually extended to increase its lifetime is very closely related to the maintenance phase. Through questionnaire survey and statistics analysis on domestic enterprises, we understand the characteristics of all the information systems in the enterprises in each phase of software maintenance operation within the maintenance lifetime and provide relevant suggestions as the reference for the administrators to improve the software maintenance. We believe that it will help the enterprises understand the characteristics, brought by the maintenance management ，and assist them to arrange the maintenance work in accordance with the importance level of arising enterprises’ benefits in the maintenance process、select appropriate latest version and finally reduce the maintenance cost of the system.
