Use Case Template for Online Shopping System Dark

Description

Use this editable UML-style use case diagram to map an Online Shopping System in PowerPoint & Google Slides. A highlighted “Online Shopping System” subsystem houses four color-coded ovals—View Items, Make Purchase, Complete Checkout, and Log In—each linked to actor icons for Customer, Authentication Service, Identity Provider, Credit Payment Service, and PayPal. Dashed “<<include>>” connectors demonstrate internal dependencies, while solid lines show external integrations. The clean container shape, subtle drop-shadows, and consistent iconography deliver a professional, easy-to-read design that clarifies functional requirements at a glance.

Built on vector-based slide masters, you can swap actor icons, relabel use cases, adjust color themes, or add additional services in seconds—ensuring your diagram stays on brand and up to date. Connector lines and labels remain fully editable, letting you illustrate complex interactions without losing alignment. Whether you’re defining system boundaries, capturing user requirements, or presenting architecture to stakeholders, this template provides a versatile, high-impact visual aid that scales seamlessly across virtual and in-person settings.
