Consistency in DFDs means that the same system is depicted the same way at every level of the DFD hierarchy. This ensures that there are no conflicting views of the system and that the analysis is accurate. Completeness refers to whether or not all necessary processes, data flows, and data stores have been included in the DFD. Balancing refers to the process of ensuring that inputs and outputs are equal at each level of the DFD hierarchy. Accuracy refers to how closely the DFD depicts the actual system being analyzed.
