Many public or private organizations have developed information technology systems for collecting, sharing and maintaining lessons learned as a crucial element of their knowledge management policies. For efficient knowledge sharing and dissemination, the contents of the learned lessons are usually codified into explicit and structured knowledge in textual form like cases, reports, research studies, best practices or guidelines that are accessible to their staff for reference. While issues about data and information quality have been widely investigated, there is little research on the quality of the content of knowledge per se. Evaluation of lessons learned systems in terms of knowledge quality has not been conducted, implying a lack of detailed criteria for effective codification of knowledge, which is one of the key factors for successful knowledge management. This paper offers a brief overview of LL followed by discussion on the quality dimensions of knowledge with a view to answering the question: “What kinds of lessons are more effective in terms of learning and transferring knowledge?” This is related to the way of evaluating LL, together with suggestions on how to apply these quality dimensions in the perspectives of context and content. For example, many lessons learned programs focus on the'what' and 'how' aspects but do not adequately address the 'why' perspective. Knowing the reasons why past practices succeeded or failed is essential for project team members in order to avoid reinventing the wheel and to achieve continuous improvement. Project team members can reach informed decisions not just by blindly following rules and decisions but also by reflecting on the reasons why their predecessors have made the choices and taken the actions specified in the lessons learned. A quality lesson learned should state the rationales behind the decisions in the content. This study contributes to project management research by showing the importance of good contextual knowledge and content in lessons learned on decision-making. The “Failure Knowledge Database”, a knowledge database of failure cases, is used as an example for illustration.  \nKeywords: knowledge management, lessons learned, failure, quality, failure knowledge database  \n1. Introduction  \n1.1 Lessons learned in knowledge distillation  \nAs an important component in knowledge management, lessons learned (LL) are the knowledge gained from people’s successful or failed experience. From the perspective of knowledge processing, an LL program can be considered as a set of concepts and techniques of collecting, validating, analyzing, storing, transferring and using knowledge from the lessons. LL is particularly important for project-based organizations, such as those in the construction industry. However, it is difficult for project teams to learn, transfer and retain knowledge, because of the diverse expertise and different backgrounds of team members, frequent personnel changes and temporary nature of projects (Lo & Fong 2009) . Various kinds of knowledge bases, case retrieval systems and document repositories have been developed to capture, store and use LL. In the following section, this paper gives a brief overview of LL and discusses general quality dimensions of LL with a view to answering the question: “What kinds of lessons are more effective in terms of learning and transferring knowledge?”which is related to the way of evaluating LL.  \nTaking the constructivist ","cbCaidPareA6suwu","https://ap.wps.com/l/cbCaidPareA6suwu","pdf",734956,"English","# Abstract\n# Introduction\n## Lessons learned in knowledge distillation\n## Types and examples of lessons learned","[{\"question\":\"Why are lessons learned important in project-based organizations?\",\"answer\":\"Lessons learned provide knowledge gained from successful or failed experiences, supporting collection, validation, analysis, storage, transfer, and use of knowledge.
