Understanding how organizational cultures interfere with a company s performance, and what are the important cultural characteristics to leverage this performance, is extremely relevant in increasingly competitive and dynamic markets. Therefore, the objective of this work is to analyze the relationship between Culture and Organizational Performance. From the literature review, a case study was conducted in a private insurance company, which stands out in the market in which it operates, being among the largest independent insurers in Brazil in Life, Private Pension and Savings Bonds and over the years, received awards and participated in the most important national financial rankings, gathering certifications that reinforce the credibility, the performance and the excellence in its management. The survey collected data on the results of organizational performance, more specifically the result of the financial indicators - Return on Sales (ROS), Return on Asset (ROA) and Return on Equity (ROE) and, by applying the Denison Organizational Culture Model - DOCS questionnaire to managers, it was possible to evaluate the key characteristics of the organizational culture, under the dimensions of Mission, Consistency, Involvement and Adaptability. The qualitative analysis of the data collected showed that there is a relationship between the results of the cultural dimensions and the indicators of profitability and suggests the importance of future research on this subject in other organizations.
