Process 1.0 has multiple inputs and outputs, which makes it a good candidate for decomposition into smaller steps. Processes 2.0 and 3.0 both have only one input and one output, so there is less need to decompose them. Additional data stores may or may not be needed in the next level of data flow diagrams, depending on how the processes are decomposed. The data flows "financial statements" and "account balances" are distinct and should not be combined.
