現今商業競爭環境中，資訊科技之策略性應用已是企業獲得競爭優勢、滿足客戶需求之首要課題，而企業因所處環境及本身特性而有不同之資訊應用層面，資訊主管被賦與之職責與管理者角色亦不相同，因此資訊主管成功演繹其管理者角色並進而參與企業決策及商業策略，以協助企業獲取並維持競爭優勢實為重要。
本研究主要就Henry Mintzberg 提出管理者角色：人際角色、資訊角色與決策角色，採用問卷調查方式，探討臺灣金融業資訊主管管理者角色演繹現況、及與非金融業資訊主管管理者角色差異。研究發現臺灣金融業與其他非金融業比較，金融業資訊主管於人際角色中的聯絡者角色、資訊角色中的發言人角色等與對於職權延伸至資訊部門外明顯相對較弱；但對於滿意現有職權、工作重心偏重於資訊工作、企業決策核心成員及對公司營運影響力、挑工作團隊等較不具顯著性；臺灣金融業應設立資訊長職位以利企業進行組織策略、資訊科技應用、金融創新整合工作；另多數金融業資訊主管雖有選修企業管理課程，但受限於公司組織架構可發展的空間有限；臺灣金融業因法規限制及承受太多保護，以致於整體競爭力較為薄弱。最後將統計分析結果結合理論，提供臺灣金融業因應全球化競爭、整合策略與資訊科技取得競爭優勢、資訊長職位設立與任用參考。

Under commercial competitive environment, the strategic application of information technology has become the first issue for an enterprise to obtain competitive superiority and to meet the customer’s need; therefore, how the IT manager deduces his/her manager’s roles and further participates in enterprise’s decision making and commercial strategy making so as to help the enterprise to acquire and maintain competitive superiority is thus very important.
This study mainly focuses on the manager’s roles proposed by Henry Mintzberg: that is, interpersonal role, informational role and decisional role. Questionnaire survey method is adopted to investigate the current deduction status of the manager’s roles of IT manager of financial industry in Taiwan and the difference between this role and that in the non-financial industry. It is found in the research that, for a comparison of financial industry and non-financial industry in Taiwan, the IT manager in the liaison of the interpersonal role, the spokesman of the informational role, the job scope is extended to the outside of information technology department is weaker as compared to that in non-financial industry; but when the current job scope he/she owns, or with the job focus more on information related, or the enterprise’s core decision making personnel and the influence on the business of the company, or the picking of work group, less significance can be seen; we suggest that more chief information officer (CIO) positions should be assigned in financial industry in Taiwan so as to facilitate the enterprise’s organizational strategy, information technology application and financial innovation; moreover, since the financial industry in Taiwan is limited by the regulation and over-protected, its total competitiveness is thus weak.
Finally, the statistical analysis result is combined with theory, and it is hoped that the result can be used as reference by financial industry in Taiwan so as to cope with globalization trend, to integrate their strategies and information technologies to acquire competitive superiority, to set up the CIO position and to assign a right person to it.
