This contribution takes the idea further and sets out by discussing production in general and the underlying mental flow models associated with this understanding. It then suggests a new model for the understanding of the nature of project production with a focus on all the flows feeding this complex process. It continues by discussing the nature of the flows and at the same time looks at the impact of their variability at the project level. And finally it looks at the present tools for project management and their suitability in a process understanding of the project where particularly the nature of Last Planner is discussed. }, author_keywords={Construction physics, flow, project management, mental models }, address={East Lansing, Michigan, USA }, issn={ }, publisher={ }, language={English}, document_type={Conference Paper}, source={IGLC}, }
