Learning from experience is one of the most important areas where companies can build a strong project management process. The end of a project is a learning opportunity, but so few projects really seize this opportunity. It requirs the presence of the key stakeholders and there willingness to study the story of the project, comparing what actually happened with what was planned: in particular comparing the risks that were analyzed with the risks that occurred, the estimates with the costs. Furthermore, the organization and structure of the project can provide pointers for the future. The learning process needs to be well prepared and followed up so that the lessons learned can be recycled into future projects.
