    Data flow diagrams are one of the three essential perspectives of SSADM. The sponsor of a project and the end users will need to be briefed and consulted throughout all stages of a systems evolution. With a dataflow diagram users are able to visualise in a physical visual form how the system will operate, what the system will accomplish and how the system will be implemented. Old system dataflow diagrams can be drawn up and compared with the new systems dataflow diagrams to draw comparisons to implement a more efficient system. Dataflow diagrams can be used to provide the end user with a physical idea of where the data they input, ultimately has an effect upon the structure of the whole system from order to dispatch to restock how any system is developed can be determined through a dataflow diagram.
