透過數位證據強化內部稽核可行性之研究-以鋁製造業公司為例

The Feasibility study of strengthening Internal Audit by Digital Evidence in Aluminum manufacturing companies

指導教授 : 曾信超

摘要


在這個微利時代,商場上的競爭日趨激烈,使得管理在企業的經營上不得不步步為營。近年來隨著IT的技術日新月益,企業經營者為了有效的整合企業整理資源,紛紛引進了資訊化系統(如EPR、APS、SCM、PDM等),主要在作業流程上進行相互勾稽及快速供資訊,供企業管理者進行決策,以提高企業競整體的爭力。   在過去人工處理的階段,常受限於時間及空間,因此在稽核的過程中,大都採取抽樣而無法進行全查。這樣的查核方式對防止企業員工有意的舞弊或無心的錯誤,效果實在有限;如今企業導入E化系統後,在平時運作系統即遵循著內部控制程序,期末稽核時更可對所有資料進行橫向與縱向的勾稽。   以往的資訊系統常被定義在企業的E化系統,本研究將資訊系統範圍擴大到數位證據。亦即對企業內部的E-Mail、圖片、影像等所有數位化資料均納入查核的範圍內。並以國內鋁業大廠為例,將過去人工作業與E化系統進行比較,來證實是否有效降低錯誤及舞弊的行為,以提高管理績效、降低企業營運風險進而增加企業獲利。

並列摘要


In this low-profit generation, the intense competition makes managers operate their businesses very carefully. In recent years, with the improvement of information technology, information systems were introduced for the effective enterprise resource integration. For instance, ERP, APS, SCM, PDM and so on. Information can be checked mutually with each other and be provided quickly by these systems. With these benefits, managers can make decisions to increase the whole enterprise competitiveness. Manual handling was limited by time and space. Thus most of the time sampling was used in an audit. It wasn’t a comprehensive investigation and couldn’t completely avoid employees’ deliberate frauds and honest mistakes. Nowadays, e-enterprises follow its internal control procedure. In a final audit, they can even check all the information both vertically and horizontally with each other. Information system was usually defined in e-system of enterprise, but in this study its definition will be expanded into digital evidence, namely E-Mails, pictures, videos and other digital information of an enterprise will be audited. This study takes a great domestic aluminum manufacturer as an example. By comparing manual handling and e-system, it attempts to prove that by using e-system whether mistakes and frauds can be reduced or not and whether it can improve management performances, reduce operational risk and increase corporate profits or not.
