You mentioned using diagrams. What exactly did you describe with their help?

Diagrams in system analysis are used to visualize various aspects of a system to better understand and describe its structure and behavior. For example:

• Use Case diagrams — describe user interactions with the system and main functions.
• Class diagrams — show data structure and relationships between objects.
• Sequence diagrams — depict the order of interactions between components over time.
• Data Flow diagrams — describe how data moves and transforms within the system.

Using diagrams, I described business processes, system architecture, interactions between modules, and functional requirements, which facilitated communication with the team and the customer.
