The main Idea of this paper is to shed some light and discuss the interesting proposal of using DFD (Data flow diagram) to prove dependability. So far DFD has been widely used to track data movement from input to output and thus making it easy to organize processes and have an overall understanding of the system. However, there hasn't been any approach to prove dependability using Data Flow Diagrams. After producing several GSN (Goal structure Notation) using DFD it was clear that it is easier to support the main goal (proving top process is dependable) with evidence simply because DFD covers and keeps track of every process, input, output and data store. This paper will explain deriving GSN from DFD and the extent and aspects of this method in detail, it will also explain how the views of DFD and GSN can be interrelated to represent a dependable system.
