Adwell advertising campaign sequence diagram orchestrates five phases from proposal through completion, involving customers, administrative staff, technical teams, newspaper companies, and website providers. The workflow progresses through campaign proposal registration, technical assessment with conditional approval gates, revision and commissioning, active advertisement production across multiple channels, and final campaign completion or termination. Each phase uses synchronous calls for immediate coordination and asynchronous returns for status updates, ensuring clear handoffs between business and technical stakeholders.
