The results obtained in this study are consistent with what was previously argued by De Long (1997), De Long and Seemann (2000), and Davenport and Prusak (2000), but had not previously been tested empirically, namely, that organizational learning culture is an important factor in the development of knowledge management practices. According to the results from testing hypotheses H1, H2, and H3, it is possible to say that companies in the sample that develop knowledge management processes and practices are companies that stimulate their employees to experiment and take an attitude of responsible risk, focus on people and on all stakeholders, learn from errors and communicate intensively and openly. In such companies, leaders are highly committed to creating, maintaining and disseminating these ideas and attitudes throughout the company.
