Case Study: Reducing Temperature Breaches by 85% Through Intelligent System Design
The Challenge: When Monitoring Becomes Noise
A national pharmaceutical distributor was facing a familiar yet dangerous problem - constant temperature alarms that no longer meant anything.
Despite having monitoring hardware in place, their legacy system lacked the intelligence and context required to distinguish minor fluctuations from meaningful risks. As a result, operators were inundated with false positives. Escalations were sporadic. Root causes went unexplored. And most critically, the same types of breaches kept recurring.
This operational noise had real consequences:
- Audit readiness was under constant threat
- QA teams were firefighting symptoms without solving problems
- Staff had become desensitised to alerts
- There was no clear way to track what had been investigated, corrected, or resolved
In an industry where temperature integrity is critical, the system was failing its purpose. The client needed more than a monitoring upgrade - they needed a strategy shift.
The Sematics® Solution: Redesigning Compliance from the Ground Up
Sematics® replaced the client’s existing infrastructure with a fully reengineered system, not just in terms of hardware but in how monitoring, alerting, and response workflows were configured.
This wasn’t a plug-and-play install. It was a bespoke design matched to their operational risks, workflows, and audit requirements.
Key Improvements Included:
| Feature | Impact |
| Contextual Sensor Grouping | Sensors were grouped by risk profile, layout, and product type to reduce noise and improve relevance. |
| Time-Weighted Alert Logic | Alerts considered both magnitude and duration, filtering out brief fluctuations (e.g. door opens). |
| Dynamic Escalation Flows | Alerts escalated differently based on site, shift, and severity - using SMS, push notifications, and voice. |
| Integrated CAPA Logging | Root cause, corrective action, and sign-off were built into each incident for full traceability. |
| Performance Dashboards | Visual tools helped QA teams spot recurring issues - like slow recovery, poor airflow, or misuse of space. |
| Audit-Ready Compliance Records | Logs included user actions, time-stamped sign-offs, and full excursion trails for instant audit access. |
Results: From Alarm Fatigue to Continuous Improvement
Within 12 months, the transformation was measurable:
- 85% reduction in temperature breaches
- Zero compliance failures across two MHRA inspections
- Behaviour change observed in fridge loading and door use patterns
- Complete audit trails for every excursion and action taken
- Quality teams freed from fire-fighting to focus on training and prevention
“We used to react. Now we improve. Sematics® gave us more than monitoring - they gave us direction.”
Quality Lead, National Pharmaceutical Distributor
Why It Worked
Sematics® delivered results not by adding more sensors - but by adding intelligence.
The system knew:
- What to alert on
- When to escalate
- Who should respond
- And how to prove what happened
This combination of reliable infrastructure and intelligent configuration enabled a cultural shift - from passive compliance to active quality improvement.
