A functional decomposition diagram is a graphical representation of workflows in a system development project. We are also able to clearly identify its use cases simply by just breaking down the name of this diagram. For instance, the word functional decomposition symbolizes the breakdown of various procedures within a process. A functional decomposition diagram looks nearly identical to that of a typical organizational chart. The catch, however, is that FDDs have nested tasks rather than an organizational chart’s chain of command supremacies. Furthermore, the nested procedures inside of each process would need to be organized in a very distinct way to show the hierarchical precedence of all of the tasks within that process. An excellent example of that is in an accounting system FDD; there may be an account payable and an account receivable processes. And typically, in an accounting receivable process, the recording of payments on the company’s permanent ledger almost always takes place after the payee’s financial institution clears that transaction from the payors. Due to FDD’s clear and concise graphical nature, a successful functional decomposition diagram will significantly improve the efficiencies of the development team as it will provide them with a broader scope of the business process. In doing so, it will be easier for the development team to get a grasp of the various business flows, hence greatly improving interdepartmental collaborations while also reducing the error rate that originates from ineffective communications and misunderstandings.
