Explore Application Modularity

Use the Module scope to understand functional boundaries and measure coupling between modules.

Step 1: Open the Module scope

In the Investigation panel, select Module.

Step 2: Read the module diagram

Each node represents a module. Links between modules show dependencies (one module calls objects in another).

The thickness or number of links indicates the level of coupling.

Step 3: Drill into a module

Double-click a module node to see the objects inside it. From there you can investigate which objects create the dependencies.

Step 4: Measure coupling

Look at the number of links between modules. A high number of links means tight coupling. Tightly coupled modules are harder to change or migrate independently.

Step 5: Use the Module Assistant

The Module Assistant can help you reorganize objects into better-fitting modules.
