系統使用者與資訊人員在資訊系統發展過程中的知覺研究-以台電公司為例

Abstract

使用者與資訊人員在發展資訊系統時會有相當多的互動行為，包括需求的訪談、分析和訂定。使用者與資訊人員在開發團隊中是否能有良性的交互作用，包含了多種因素，簡要的歸納：就是有效的溝通。較複雜的因素中有一個潛在的因素就是使用者與資訊人員的知覺是否存有差距。 若開發團隊中使用者與資訊人員對系統分析師執行職務所需之技能與角色的的知覺存在差異，則會影響到行為；同樣，當開發團隊中使用者與資訊人員對使用者投入的程度知覺一致，有助減少系統開發的阻力。 本研究以台電公司的使用者與資訊人員為研究對象，採問卷調查方法探討系統開發過程中這二類人員的知覺，回收樣本共146份，利用多變量變異數分析、剖面分析等方法檢定後發現二群人員對於「系統分析師執行專案應具有的技能」知覺有顯著差異，對於「系統分析師執行專案應展現的角色」，知覺亦存在顯著差異，對於「系統分析師執行專案所應得到的非物質獎勵誘因」，知覺則無顯著差異。另外對於「使用者投入或參與的程度」，在系統的分析設計階段，知覺無顯著差異；但在系統的測試階段，則有顯著差異。至於「使用者投入或參與的程度」，與所認知到的MIS系統開發品質之間，資訊人員知覺是彼此並無相關，使用者知覺則是有關。

System development efforts involve large degree interaction between IS users and IS staff, such as interviewing, requirement analyzing and definition. The relationship could translate directly to success or failure depends upon how well they work together. Problem that result from this interaction between these two diverse groups has been recognized. In its simplest formulation, the problem involves effective communication. In its more complex form, there were perceptual differences existed in these two groups. Perceptual difference among IS users and IS staff about how system analysts perform their jobs, include job skills and job roles within a project team, if they were existed, could affect behavior. When the extents upon perceived User Involvement of these two groups are the same, less obstacles occur during system development will be recognized. In a survey of perceptual difference about IS users and IS staff in the information system development life cycle from Taiwan Power Company, by using MANOVA and Profile Analysis methods are implemented. Results from 146 questionnaires show that IS staff and IS users differ significantly in their perception of skills and roles for system analyst, but not significant for non-salary incentives. In system testing stage, the two groups significantly show different views regarding User Involvement. At system analyzing and designing stage, these two groups show the same perception. Results also show that perceived User Involvement are correlated with information system quality, true for IS users but not for IS staff.
