本研究主要目的,在於探究技術變革下人機協作的任務、職能與角色轉變。在文獻階段,首先闡明工作分析的意義與重要性,接著探討適合本研究分析的任務與職能架構,並整理技術變革相關研究和人機協作關係與任務技能的可能轉變。研究設計以質性訪談方法對個案公司之印刷機車長進行工作分析,萃取蒐集之質性資料以獲取其中意義與脈絡。本研究發現印刷機車長具有共通的任務與職能構面,歸納績優車長採取的自主性任務、高嫻熟度技能與能力特質,對照過去的差異及轉變,並發現車長未能主動察覺管理職能的重要性。研究結果顯示,自動化技術進步對個案公司印刷機車長的影響不僅實現部分任務的替代與互補,同時使車長整體工作任務朝趨向複雜化、工作自主性與深化工作技能。本研究依研究結果於文末提出管理意涵,作為個案公司實務建議參考與後續研究方向。;The main purpose of this study is to explore the Transformation of tasks, individual competences and roles in a human machine collaboration under technological change. In the literature stage, first clarify the significance and importance of job analysis, and then discuss the tasks and competences framework suitable for the analysis of this study, and sort out the research related to technological change and the possible transformation of human-machine collaboration and task skills. The research design used a qualitative interview method to analyze the work of the printing company′s captain in the case company, and extracted the collected qualitative data to obtain its meaning and context. This study found that printing supervisors have common tasks and functional aspects. They summarized the autonomous tasks, highskilled skills and ability traits adopted by the excellent printing supervisors, compared with the past differences and changes, and found that the printing supervisors failed to actively detect the management functions. Importance. The research results show that the impact of automation technology advancement on the printing supervisors of the case company not only realizes the replacement and complementation of some tasks, but also makes the printing supervisor′s overall work tasks tend to be more complicated, work autonomy and deeper work skills. This study proposes management implications at the end of the article based on the results of the study, and serves as a reference for practical recommendations of case companies and followup research directions.
