* No centralized notification history; * Users complain about duplicates and delays; * No unified SLA, metrics, or control center. Goal Design a new Notification Platform that: * Aggregates events from various sources (CRM, Support, Security); * Routes them by type and channel (email, SMS, Telegram, push); * Ensures uniform templates, logging, and observability; * Supports SLA (p95 ≤ 3 seconds for delivery); * Allows for future scaling and channel expansion. Candidate task 1. Define the functional requirements of the system. 2. Describe the non-functional requirements (reliability, performance, error handling). 3. Create a context diagram (C4 Level 2). 4. Add a sequence diagram, for example, sending a message from a source.
