A functional decomposition diagram lays out the steps of a system from start to finish in chronological fashion. Illustrating any basic function and its sub-functions in a top-to-bottom fashion, these diagrams show the functional breakdown of how systems unfold and how every step connects to the next. By capturing the moving parts of a complex system in one simplified visualization, functional decomposition diagrams can provide teams with a more holistic understanding of their multi-faceted project or software build.

Functional decomposition diagrams are useful because they help address and anticipate any hangups. You might use a diagram to locate the source of a problem at a microscopic level or catch a snafu before it begins. When you help your team understand every step of the process, you’ll see creativity and efficiency bloom.

To start, reallocate your valuable time from creating a homemade diagram and tap into FigJam’s customizable functional decomposition diagram example. Work with your team to deconstruct functions and their sub-functions, then plug them into your template’s descending rectangular boxes. Next, trace the impact of every element by connecting each box vertically. Columns differentiate between areas of the project, but ultimately, the diagram reveals how each moving part relates to the whole.

Simple visuals and directions from FigJam will make drawing a breeze. Use the task of filling in our template as a team-wide activity, and get to the root of even the most tangled systems.
