It is obvious that a puter system can be evaluated according to different types of criteria – ease of use, cost, reliability , integratibility , and so on. ? 電腦系統(tǒng)的評估可以依據(jù)不同的標(biāo)準(zhǔn)，如「容易使用」、「成本」、「穩(wěn)定性」以及「整合性」等等。 (4) 未來可能的資源消耗。 (2)系統(tǒng)產(chǎn)出或效益是否有達(dá)到使用者 (群 )的要求標(biāo)準(zhǔn) 。 (3) the point at which a new system or system refinements are needed。自動化系統(tǒng)評估 Evaluation of Automation Systems 張?jiān)Ｐ? . Lancaster and Beth Sandore, Technology and Management in Library and Information serverices:Chapter14 Evaluation of automated Systems,1997,196225. ? 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 munity。 (4) possible future resource consumption. ? 評估自動化系統(tǒng)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(tǒng)或更新系統(tǒng)是否符合合約需求 。 (3) 明確指出新系統(tǒng)或系統(tǒng)強(qiáng)化的需求 。 1 ? ? ，與 TCO的觀念相符。 ? 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 acplishment of automation. ? 經(jīng)過評估北美 54個主要的圖書館， Johnson(1991)發(fā)現(xiàn)使用者感覺「容易使用」是選擇系統(tǒng)的主要考量。 ? Peters(1988) identifies three types of systems evaluation: (1)functional – to determine whether a system’s features meet the library’s needs。 and (3) performance – to reveal whether the system capacity can meet present or anticipated future demands. ? Peters定義系統(tǒng)評估三個型式：功能性 —決定系統(tǒng)特性是否符合圖書館需求；經(jīng)濟(jì) —決定系統(tǒng)的支出 (時間與金錢等 )；效益 —系統(tǒng)是否能夠符合現(xiàn)今或未來的需求。 3 ? ? Thinking—TAM模型屬於上述兩種評估方法中第 2種型式。這類評估可用於系統(tǒng)的選擇、系統(tǒng)的接受性評估以及系統(tǒng)強(qiáng)化或替換的決策評估。 ? A point value may be assigned to each feature, and a differential weighting scheme may be established to place emphasis on features that are considered more important than others. In other cases, features are assigned an equal rating of 1 or 0. system scores can be derived from the grids, with subtotals to indicate system strengths in particular areas, and total scores to indicate overall performance. ? 在 Checklist中 , 可針對不同的特色指定權(quán)值以強(qiáng)調(diào)重要的系統(tǒng)特性。 Questions A B C D E F G H I J K L D O B I S Geac NOTIS P A L S D R A H O M e H O M e there adequate logon instruction (. explain which terminal types are supported) ? ? ? ? the contents and coverage of the OPAC ckearkt exokaubed? ? ? ? ? ? ? ? ? ? ? the key equivalencies explained for remote user’s keyboard? ?
