Purpose – The ISO norms, related to the world of project management, such as: ISO 21500 “Guidance on Project Management”; ISO 10006 “Project and Knowledge Management, a shared approach, to Improve the enterprise innovation” and ISO 31000 “Risk management – Principles and guidelines”, will guide project managers in defining and managing projects. These standards define the guidelines to manage projects efficiently and effectively but not always in an explicit mode, the important principles of General Management. Some of these elements are important in the management of the Historical Information, Lessons Learned and Continuous Improvement. The standards defined by ISO are not limited to suggest the mode of project management in particular contexts as can be risk management or quality but, reading between the lines, give us important lessons for the management of organizations in a project management context. Through a detailed analysis of these norms are to highlight the principles through which organizations and managers can manage more effectively and efficiently departments or companies. Another result is to define the principles through which organizations manage information and put them to our disposal by the organization in order to improve organizational processes. Design/methodology/approach – I propose an approach for improving the profitability of the projects through the management of an integrated system of knowledge management in the enterprise organization. The approach involves the analysis of the most important ISO norms related to the project management context to define the General Management principles to improve the shared knowledge. Originality/value – The main objective is the identification of the main concepts of general management inherent to the most important ISO norms in the context of project management. This methodology highlights the need to manage all the knowledge generated within at Project That Is, from the organizational point of view (historical information, best practices, knowledge of the processes, lessons learned …), in order to Improve organizational processes, reduce the time of project management and reduce the cost of the project. One of the main Objectives to Achieve is the continuous improvement in project management. Practical implications – The outcomes of the application, through a correct application of the main concepts of general management is the diffusion of the project management culture, the definition of the main rules by which the company is able to govern the business processes, the definition of a proper process for the management of knowledge generated by the same organization through project management and through it the ability to reach what is the ultimate result to which an organization may tend: the continuous improvement.
