Abstract: A method (200) for integrating systems engineering (102) and project management tools (104), the method (200) including the steps of: obtaining component parts and life cycle activities of a system (202); creating a system information model by selectively and individually linking parts and activities with tasks, resources, time and costs (204); updating the system information model by selectively and individually adding or modifying parts, activities, tasks, resources, time, costs and links therebetween (206); storing versions of the system information model (208); processing versions of the systems information model into end-user information to enable life cycle analysis of the system (210).
