The document presents a systemic lessons learned knowledge (Syllk) model for organizational learning through projects. It discusses barriers and facilitators to effective lessons learned practices across five elements: people (culture, social, learning), systems (technology, infrastructure), knowledge management processes, and research methodology (action research). The Syllk model is presented as a conceptual framework to enhance organizational learning by addressing barriers across these different elements. Contact information is provided for the authors to obtain further details on the Syllk model and its application in project organizations.
