According to Tommelein et al.1, workflow can be characterized in several different ways. In manufacturing, it is defined by stationary machines with partially completed products being transported from one to the next. In construction, the products being built tend to be stationary, whereas crews of various trades move from location to location and complete work that is prerequisite to starting work by the following crew.

Lean games developed to teach the Lean principles of Pull & Flow have traditionally been focused on Lean manufacturing, where the semi-assembled parts move from one workstation to the next. In a Value Stream you can identify three kinds of flow: materials, information, and people. In construction, the different trades move from one site to the next, so we created an educational tool around this idea for people from construction industry to understand these principles. – See more at:
