Each element is represented by a lifeline that shows its active duration. Messages between these lifelines illustrate the specific actions taken, such as placing an order or confirming payment, providing a chronological view of the process.

Why should developers use a sequence diagram for food ordering systems?

Developers use these diagrams to identify logic flaws or communication gaps between different software modules. By visualizing the step-by-step interaction, teams can ensure that orders are processed correctly and that payment data is handled securely. It also serves as a valuable blueprint for coding the backend logic and integrating third-party restaurant APIs effectively.
