Alert & Notification System
SHIPPEDA tiered alert system that separates informational updates from actionable warnings and critical failures, with configurable thresholds per sensor per zone.
The problem
The existing alert mechanism sent every sensor deviation as an identical email notification. Alert fatigue was severe — operators had stopped opening notifications entirely, missing genuine failures.
When everything is urgent, nothing is. Alert fatigue is a design problem, not a user problem.
The solution
A three-tier alert model (info / warning / critical) with visual and audio differentiation in-app. Critical alerts are persistent and require manual acknowledgment. Warning alerts are batched hourly. Info updates are passively logged.
Key decisions
Push notifications were requested early. We held them for v2 because configuring per-device thresholds for push required backend infrastructure not yet built. The in-app system shipped first and validated the tier model before investing in push delivery.
