Functional decomposition template.
A functional decomposition template breaks one broad capability into its major functions and the smaller activities beneath them. This functional decomposition template maps customer support from the top-level service through request handling, resolution, and continuous improvement. It uses a top-down hierarchy, so it is useful for understanding scope without implying that every branch happens in sequence.

Scenario
This functional decomposition shows how a support operations manager can break one service capability into three major functions and their detailed activities. It uses a top-down flowchart because that type presents a clean parent-to-child hierarchy without sequence, people, or IDEF0 annotations.
Key decisions
- The top function is a broad business capability rather than a single task.
- Three sub-functions separate request intake, resolution, and ongoing service improvement.
- Two leaf functions beneath each sub-function keep the first-level breakdown readable at card size.
- The arrows show decomposition relationships, not a time sequence or approval workflow.
When to reuse this
Use this hierarchy to define scope, assign ownership, or decide which function needs deeper analysis. Use a process flowchart when the order of steps, decisions, and handoffs is the main question.
