This paper examines mechanisms to use lessons learned on individual projects within an organisation. A Delphi study highlighted the organisation’s responsibility for incorporating knowledge from projects into a project management methodology. Knowledge from a project should be transferred through a centralised knowledge management function that should evaluate codified knowledge within the context in which it was generated, determine how the knowledge should be used, and maintain the explicit knowledge database and the knowledge flow process. Based on a literature review, structured interviews, archived data, and a Delphi survey, a framework for transferring knowledge to the organisation is proposed. The framework enables the organisation to motivate and guide knowledge transfer within a methodology that indicates where, when, and how knowledge transfer and use should take place.
