Learn the essentials of process flow diagrams pfd including the history benefits and helpful tips with this guide. Similarities between sequence and activity diagram.
Activity diagrams model the control flowing from one activity to another especially good at the logic of conditional structures loops concurrency. This kind of diagram shows the flow of chemical materials and the equipment involved in the process. The only difference between these words is that process mapping refers to the actual process of creating a diagram. A flowchart is a picture of the separate.
