自動化系統評估Evaluation of Automation Systems 張裕幸 F.W. Lancaster and Beth Sandore, Technology and Management in Library and Information serverices:Chapter14 Evaluation of automated Systems,1997,196-225. Evaluation of the performance of an automated system can provide several useful types of management information on (1) whether new or updated systems meet contract requirements; (2) whether the system is living up to the performance and output standards of its user community; (3) the point at which a new system or system refinements are needed; (4) possible future resource consumption. 評估自動化系統的效益可以由下列幾種有用的管理資訊予以獲得：(1)新系統或更新系統是否符合合約需求; (2)系統產出或效益是否有達到使用者(群)的要求標準; (3) 明確指出新系統或系統強化的需求; (4) 未來可能的資源消耗。1 -------------------------------------- 1.第四項資訊即考慮到未來潛藏性的成本支出，與TCO的觀念相符。 It is obvious that a computer system can be evaluated according to different types of criteria – ease of use, cost, reliability , integratibility , and so on. 電腦系統的評估可以依據不同的標準，如「容易使用」、「成本」、「穩定性」以及「整合性」等等。 In her survey of 54 major research libraries in North America, Johnson (1991) discovered that ease of use by patrons was a major consideration in the selection of a new system. – above cost and, perhaps surprisingly, ease of use by staff. Her found that these same libraries considered improvement of user services as the major objective of automation and improvement service to users as the major accomplishment of automation. 經過評估北美54個主要的圖書館，Johnson(1991)發現使用者感覺「容易使用」是選擇系統的主要考量。2而她亦發現改善使用者服務是自動化系統的主要目標，亦是自動化的使命。 Peters(1988) identifies three types of systems evaluation: (1)functional – to determine whether a system’s features meet the library’s needs; (2)economic – to determine the affordability of a system; and (3) performance – to reveal whether the system capacity can meet present or anticipated future demands. Peters定義系統評估三個型式：功能性—決定系統特性是否符合圖書館需求；經濟—決定系統的支出(時間與金錢等)；效益—系統是否能夠符合現今或未來的需求。 There are obviously many possible ways in which approaches to the evaluation of automated systems can be categorized.
