This paper proposes a model and a knowledge audit methodology, which have been developed by focusing on the core processes approach. Organizational and knowledge management criteria are considered to select the core processes to be audited. The model proposes an organizational knowledge auditing, which additionally allows reusing the audit outcomes when a technological solution is needed to improve knowledge management in organizations. The proposed knowledge audit methodology contains ten stages. The application of this strategy cyclically will be an efficient tactic to audit the key knowledge within an organization and detect some opportunities to make immediate improvements. After implementing this methodology in its entirety, it will be possible to know if the organization has valuable assets, knowledge flow and adequate organizational atmosphere to carry out knowledge management initiatives. 1.
