Alarm Sensitivity vs. Alarm Overload
Deploy correlation and dynamic thresholding to suppress non-actionable alarms, preserving operator attention for events with genuine service impact.

Business Context
Highly sensitive alarm systems can detect small deviations before they develop into serious service problems. Increasing sensitivity, however, also generates more notifications from transient events, correlated failures, duplicate symptoms, and conditions that do not require intervention. Excessive alarm volume can overwhelm operators and make genuinely important events harder to identify.
Telecommunications TRIZ Resolution
Alarm systems should distinguish between raw technical events and conditions requiring operational attention. Correlation, suppression, dependency analysis, dynamic thresholds, service-impact information, and event aggregation can reduce noise without reducing underlying detection capability. Sensitivity can also vary according to equipment condition, service criticality, and network state.
Applicable TRIZ Principles
Principle 2 – Taking Out removes duplicate, consequential, and non-actionable alarms from operator workflows.
Principle 15 – Dynamics adjusts alarm thresholds according to network conditions.
Principle 23 – Feedback improves alarm rules using information about actual incidents and operator responses.
Expected Outcome
Earlier detection of significant conditions
Lower operational alarm volume
Improved operator attention
Faster identification of actionable events
Decision Indicators
Early indicators include:
Operators routinely ignore or suppress large numbers of alarms.
Major incidents generate hundreds of related notifications.
Alarm counts increase without corresponding growth in actionable events.
Static thresholds generate frequent transient alarms.
Important alarms are discovered late because they are hidden among low-value notifications.
