Several process improvement methodologies have emerged in recent decades, but a lack of studies continues on their applicability and effective results in organizations. This article analyzes the Lean Sigma methodology implementation results in the cost and time allocation process for a multinational oil company IT application in Brazil. The analytical criteria were based on the literature review: A) cost, b) time, c) quality, d) effectiveness, e) efficiency and f) internal customer satisfaction. The action research methodology was used and the findings showed Lean Sigma improved the IT application, however it revealed the methodology has low adherence to processes where the intangibles and people participation has greater influence.
