This paper presents the application of an Interactive Method for Modelling and Knowledge Management on Business Environment for an Organizational Unit of Road Infrastructure Operation, from the Brazilian National Ground Transport Agency. As part of an innovative project named MIKM for the Knowledge and Information Manage Model of this agency adopts Knowledge Management fundamental concepts, knowledge and competence, mobilized by professionals on their activities for building information goods. For the method's development and application were needed activities of identification, collection, mapping, representation and analysis of the knowledge and competences needed to the execution of the activities related to knowledge assets of the already mentioned Organizational Unit. Materials and documentation available were analyzed and techniques of meetings and interviews with managers and employees in the steps of identification and collection; for mapping a methodology developed by Rezende (2007) and a knowledge tree concept (Authier and Lévy, 1992) was applied. On knowledge management's analysis and improvement proposals the knowledge conversion modes (Nonaka and Takeuchi, 2009) about knowledge flow, from Road Infrastructure Cycle of Regulation.

This paper presents the main contributions of the Iterative Model for Knowledge Management proposed by Universidade Federal Fluminense (UFF) in cooperation with the Brazilian Agency for Land Transport Regulation (ANTT). The method's great innovation is to combine to the KM diagnosis and prognosis, the concepts of conversion and knowledge flow, with the application of the 5W1H method and Enterprise Architect (EA) software to integrate the models built, also allowing its graphical representation. The models and products obtained have allowed: to understand the culture of the Agency's current KM; view existing gaps and needs in their knowledge flow construction and in the process of converting knowledge; propose a set of KM practices and tools appropriate to their reality and predict future actions of improvement that impact on the efficiency of the regulatory process.
