企業在面對外界法規或準則改變時，必須慎重面對並改變內部流程以求法遵，而參照過去的經驗，企業可藉由資訊系統以提升員工對於企業推動變革的調適。本研究以資訊系統成功模型作為主要研究架構，並以一例一休為例，探討人力資源系統在因應外部法令而調整的過程中，其輔助企業施行相關法令之有效因素。並以製造業公司為個案，對員工進行問卷調查，而後透過PLS分析並探討系統品質、資訊品質、政令宣導、組織變革認知、使用者滿意度及實施成效各變項間的影響。結果發現系統品質、資訊品質及政令宣導對組織變革認知有正向顯著影響，系統品質及政令宣導對使用者滿意度有正向顯著影響，組織變革認知對使用者滿意度有正向顯著影響，資訊品質對使用者滿意度的反應則無顯著影響。統計結果顯示為了增進實施成效，應考慮改善政令宣導及系統品質和相關資訊品質，其中加強政令宣導及系統品質的效果更為顯著。最後，針對研究結果提出管理意涵及後續研究建議。
