Investopedia explains 'Functional Decomposition'

Basically, functional decomposition takes something complicated and simplifies it. The individual elements of the process and their hierarchical relationship to each other are commonly displayed in a diagram called a functional decomposition diagram. Other common business methods for simplifying complex problems and processes include decision trees, which allow users to consider multiple possible solutions to a problem, and flow charts, which show the sequence of a process.
