    摘要: 長久以來,系統發展就被視為一件高難度的工作,所以,也就一直是藝術成分多於科學。電腦輔助軟體工程(CASE)是對軟體工程領域予以自動化。本研究試圖瞭解CASE在台灣使用情況。首先,經由文獻探討,發展出一份問卷。分為一般廠商及教師與CASE廠商二種版本。經先導測試後,以抽樣調查法對下列團體寄發問卷:國內前一百大企業、政府機關、金融業、資訊經理人協會會員、資訊管理學會會員、大專資管科系中專長為系統分析與設計或軟體工程的教師、CASE廠商及其使用者群。問卷共寄出786份,經二次催收,有效回收問卷數為226份。 我們以因素分析分別將系統發展中的嚴重問題、知覺CASE使用上會有的問題、對CASE的態度、以及CASE成功因素予以濃縮成幾個因素。而後嘗試地探討包含答卷者個人、組織、資訊部門、及系統發展等方面的眾多外部變數對上述問題與態度的影響。接著,本研究嘗試在加上「對系統發展中問題的嚴重性」這變數後,測試Davis(1986)之資訊科技引進態度模型。結果發現,「知覺CASE使用上會有的問題」不會對「認為CASE可改進系統發展問題的程度」,或「對CASE的態度」產生統計顯著影響。而在探討成功使用CASE的決定因子模型上,我們發現「方法論的使用」(含引入CASE之前的使用及與CASE提供的方法論的一致)是唯一顯著的成功因素。而單以「方法論的使用」來區別使用CASE較成功與較不成功者,其區別正確率也已達75%。
    System development has been recognized as a task with a high level of complexity and remains more of an art rather than a science. Computer-Aided Software Engineering (CASE) is the automation of the software engineering discipline. The aim of this research is to understand the CASE usage in Taiwan. First, through literature review, we developed a questionnaire including two versions---one for general respondents, the other for teachers and CASE agents. After pre-testing, the questionnaires were sent to the following: Top 100 business, government agencies, financing industry, members of Information Manager Association, members of Society of Information Management, teachers with specialty of system analysis/design or software engineering in MIS departments of universities, CASE agencies and their user groups. 786 questionnaires were sent. 226 effective samples were obtained after we sent two follow-up letters. Factor analyses were used to condense several factors from serious problems in system development, perceived problems in CASE usage, attitude toward CASE and success factors for CASE implementation, respectively. ANOVA were used to explore the possible influence of many external variables (including respondent`s personal, organizational, information department and system development) on those problems and attitude. Then, after including the variable "the critical problems in system development", we tested the attitude model about information technology adoption proposed by Davis (1986). We have found that "the perceived problems in CASE usage" has statistically significant influence on neither "perceived CASE improvement for system development critical problems" nor "attitude toward CASE". About the determinants of CASE successful implementation, we have found that the "methodology usage" (including the usage before CASE adoption and the consistency with methodology supported by CASE) is the only statistically significant variable. In addition, using only "methodology usage" variable can discern relatively successful adopter from relatively unsuccessful adopter with 75% correct classification rate.
