過時管理(obsolescence management)一直是資訊科技領域中的一個關鍵因素。一 起處理不當的過時問題可能會迫使公司付出高昂的恢復成本或冗長的系統停機時間。 目前,廣為使用的過時管理模型由回應型、主動型和戰略型方法組成。然而,多數研 究通常只會使用其中一種方法來解決過時問題。本研究提出了一個同時使用回應型與 主動型的過時管理方法的模型,我們認為緩解措施應該兼顧過時問題發生的前與後, 並且這兩種方法都應該能更真實地反映實際應用情況。本模型認為前視(foresight)和 組織留神覺知(organizational mindfulness)能作為促進公司執行回應型與主動行的過時 管理方法的因素,並且兩種方法的使用能促進組織的資訊科技一致性。 本研究的模型包含六個假設,並從台灣前 1000 家製造公司抽樣進行測試。研究 結果表明,無論是回應型與主動型,企業前視的能力都與組織的過時管理能力無關。 相比之下,組織留神覺知對回應型與主動型的過時管理有正面的影響。除此之外,我 們的結果表明,回應型與主動型過時管理方法都對企業的資訊科技一致性產生了顯著 影響。最後,結論部分包含本研究的重要性、限制和未來的研究方向。;Obsolescence management has always been a critical factor in information technology. A badly handled obsolescence issue can endanger the firm with high recovery costs or system downtime. Most studies thus far have utilized a well-accepted model of obsolescence management, which consists of reactive, proactive, and strategic approaches. These studies usually use one of these approaches as a solution to the obsolescence problem. This paper proposes a model of the simultaneous use of proactive and reactive obsolescence management approaches as we believe mitigate measures should be taken both before and after the obsolescence, and considering both approaches should more faithfully reflect the reality in practice. The model introduces foresight and organizational mindfulness as the factors that facilitate the firm performing both approaches, leading to greater IT alignment of the firm. The research model contains six hypotheses and is tested with data from the top 1000 manufacturing firms in Taiwan. The findings show that foresight is not related to an organization’s obsolescence management either proactively or reactively. By contrast, , organizational mindfulness is positively associated with both proactive and reactive obsolescence management. Finally, our result indicates that IT alignment is positively influenced by both proactive and reactive obsolescence management approaches. Implications, limitations and future research directions of the study are provided.
