For what tasks do you use Sequence Diagrams in projects and who is the consumer?

Sequence Diagram is used to visualize interactions between objects or components of a system over time. In projects, it is used for:

• Understanding and documenting business processes and use cases.
• Designing interactions between modules or services.
• Explaining the logic of complex functions or algorithms.

The typical users of such diagrams are system analysts, developers, testers, and sometimes clients who need to understand how message exchanges and calls occur between parts of the system.
