The number of levels to which the decomposition is performed will depend on. FDD turn complicated steps into a simpler version. A functional decomposition diagram is a picture that engineers draw to help them understand how all of the general tasks and subtasks in a design fit together.

### An analyst first must understand an organization's business functions before he or she can begin developing information systems.

Functional decomposition is about partitioning the functionality of a big complicated system, into smaller, preferably simpler For example, if you have an FDD diagram describing a blogging system.

The Functional Decomposition AntiPattern is fine when an object-oriented solution is not required. I was wondering if in general the Functional Decomposition Diagram I came up with makes sense. Functional Dependency plays a vital role to find the difference between goo.
