Lahendusaja

Lahendusaja, Estonian for “solution time” or “time to resolution,” is a metric used in IT service management and customer-support contexts to measure the duration between when a problem is reported or detected and when it is resolved or closed. It is used to assess service performance, guide process improvements, and monitor SLA compliance.

The metric can be calculated in several ways. It is commonly reported as the mean time to resolution (MTTR) across incidents, but medians or percentiles are often preferred to minimize the impact of unusually long outages. Lahendusaja can be analyzed for all incidents or broken down by category, such as service, team, or severity. Clear definitions of what constitutes “resolution” and “closure” are important, as some contexts distinguish between a temporary workaround and a permanent fix.

Factors influencing lahendusaja include problem complexity, the number of active incidents, availability of skilled personnel, the quality of the knowledge base, automation levels, and escalation policies. Data quality and incident classification also affect the reliability of the metric, and there is a risk that a focus on speed could undermine solution quality if not balanced with robust testing and verification.

Applications and improvements: organizations use lahendusaja to gauge service quality, manage capacity, and ensure SLA compliance. Strategies to reduce it include root-cause analysis, better incident triage, enhanced knowledge sharing, automation of repetitive tasks, proactive monitoring, and standardized incident response playbooks. Care should be taken to interpret the metric alongside other indicators of service health, such as customer satisfaction and first-time resolution rates.
