In the competitive business environment, intangible assets represent a source of innovation and creation of new levels of value. In this context, Knowledge Management has received increasing attention from the organizations. They have tried to understand its meaning and to find management methods that ultimately ensure positive impacts on the company performance. Literature review demonstrates the importance of the relationship between Knowledge Management and firm strategy, competency and result management, for the consequent superior business performance. Thus, the main purpose of this study was to identify if Brazilian companies establish any relationship between Knowledge Management and firm strategy, competency and result management, and the impact produced by these relationships on business results. Therefore, a field survey was carried out about 100 Brazilian companies, with the intention of measuring, within a representative sample comprised of multiple industries, the relationships inherent to Knowledge Management, checking the existence of these relationships and assessing the impact on the results of these companies. Different analysis methods were employed to provide a broad basis to help understand and validate data. From the results of statistical analysis and qualitative constructs, important generalizations were suggested. The main conclusion of this study indicates that a significant percentage of Brazilian companies already establish a relationship between Knowledge Management and enterprise strategy, competency and result management, and that these organizations are excelling in terms of business performance.
