Here is what appears to be a doorway to a veranda. The crack makes it appear as if there was no reinforcing mesh applied, in an area where there should be mesh diagonally along all corners. In actuality, if it is a transition between a house on the one side (right) and a veranda/porch on the other (left), there should be a control joint running directly vertical from the edge of the door to allow for movement.
Control joints should be located between levels of a house as well, such as between the first and second floor. The purpose of control joints is to control where (as opposed to if) a building will crack. For that reason, the groove that is cut into the insulation is filled with caulking, which is flexible and will not allow water in.
Most manufacturers will have a certain square footage limitations, around the 400 square foot area. That means that on a standard 10′ height floor, the wall can not be longer than 40′ without adding a vertical control joint.
