| 中文摘要 | 由於軟硬體技術及相關系統開發工具與理論的快速發展,主從式架構已成為企業資訊系統共通的建構方式,且因快進應用系統開發工具之採用,大幅提升並改善資訊系統的開發效率。相較於傳統的開發方式,利用快速應用系統開發工具有整個開發週期中各階段所需投入之人力一感間並不相同,因此以程式行數評估軟體系統規模及估算成本的方式已有不足之處。本研究以國立中山大學軟體研發中心實際進行的三個系統開發個案為例探討討快速應用系統開發工具於資訊系統統開發過程中,每個階段實際發生的活動及所佔之時間比例等相關議題。研究結果發現快速應用系統開發工具於雛型開發與測試階段之時間成植,約佔總時間成本的50%至65%之間。此多個案之分析結果將有助於專案經理與資訊系統開發人員,深入瞭解並確實掌控軟體開發專案在系統開發各階段可能發生之活動及其所佔之時間比例,以做為估算系統開發成本侑資源配置的重要依據。 |
| 英文摘要 | In the Internet age, the state-of-the-art information and communication technology (ICT) and software system development techniques are evolving at a rapid rate; the client/server architecture becomes a common way of the enterprise information system. The information system development efficiency has been largely improved by the rapid application development tools (RADTs). The resources, such as costs, man powers and time invested in various systems development stages among the entire system development life cycle, also have rudimentary changes. The traditional method, counting numbers of lines in programs, to evaluate software system scale appraisal and cost assessment apparently has its deficiency. Based on exploratory case analyses of three firms in the Software Research Center of National Sun-Yat Sen University, this study investigated issues of software development project management. The activities and time in each stage that actually occur and account for the proportion in relation to the application of RADTs were studied. The findings show that the cost invested in the stages of prototyping systems development and testing by RADTs technique were approximately accounted for 52% to 65% of the total development cost. Possibly, each activity and its development operation in various system phases of exploitation should accounts for the proportion, the accurate estimate systems development cost and the resources distribution. The results are useful for project managers and the information system development to thorough understand and well control a software development project. |
