Time to Resolution

5 min read

Also known as: TTR, Mean Time to Resolution, MTTR, Resolution Time

Time to Resolution (TTR) is the total elapsed time from when a support ticket opens until the customer's issue is fully resolved and closed.

Definition

Time to Resolution measures how long it takes your support team to fully solve a customer's problem, from the moment a ticket is created to the moment it's marked resolved. It includes investigation, escalation, back-and-forth with the customer, and the final fix — not just the first response.

Support teams track TTR per ticket and then roll it up into averages, medians, and percentiles (p50, p90, p95) segmented by issue type, priority, channel, or agent. It's typically reported in business hours rather than wall-clock hours so weekends and off-hours don't distort the number.

TTR is distinct from First Response Time (how fast you reply) and Time to First Action (how fast someone touches the ticket). A team can have a fast first response but a slow TTR if tickets stall during investigation or hand-offs between tiers.

Why It Matters

Resolution speed is one of the strongest predictors of customer satisfaction and renewal. Every additional day a ticket sits open compounds churn risk, especially for revenue-blocking issues like billing errors, login failures, or broken integrations. Faster TTR also lowers cost-per-ticket because agents spend less time context-switching back into stale threads.

When teams ignore TTR and only optimize for first response, they end up with fast acknowledgments and slow fixes — which customers see right through. Tickets pile up in 'pending' status, escalations get lost between tiers, and the same root-cause issues resurface because no one has time to document fixes. CSAT drops, NPS detractors grow, and your support team burns out chasing a backlog they can never clear.

Examples in Practice

A B2B SaaS support team segments TTR by ticket type and discovers integration tickets average 38 hours while password resets close in under 20 minutes. They route integration tickets directly to a specialist queue instead of starting at Tier 1, cutting that category's TTR in half within a quarter.

A 50-person ecommerce brand notices p90 TTR on shipping disputes is 6 days because agents wait on carrier responses. They build a templated carrier-escalation workflow and pre-authorize refunds under a threshold, dropping p90 to 36 hours and lifting post-resolution CSAT by 22 points.

An agency's client-services team uses TTR as a contractual SLA metric. By tagging tickets with priority on intake and surfacing aging tickets in a daily standup view, they hit their 24-hour P1 resolution SLA on 97% of tickets and use the data in QBRs to justify retainer renewals.

Frequently Asked Questions

What is Time to Resolution and why does it matter?

Time to Resolution is the elapsed time from ticket creation to full resolution of the customer's issue. It matters because it directly correlates with CSAT, retention, and support cost — customers judge your team less by how fast you reply and more by how fast you actually fix things. Tracking TTR also exposes bottlenecks in escalation, tooling, and staffing that other metrics hide.

How is Time to Resolution different from First Response Time?

First Response Time measures how quickly an agent replies to a new ticket, often within minutes. Time to Resolution measures the full lifecycle — from open to closed — which can span hours or days. A team can excel at FRT and still have a poor TTR if tickets stall in investigation, await customer replies, or get bounced between tiers without ownership.

When should I prioritize Time to Resolution over other support metrics?

Prioritize TTR when customer feedback shows people feel ignored after the initial reply, when churn analysis ties cancellations to unresolved tickets, or when your SLAs are contractual. It's especially critical for revenue-blocking issues — billing, access, outages — where every hour of delay creates direct business impact for the customer.

What metrics measure Time to Resolution effectively?

Track median TTR (less skewed than averages), p90 and p95 to surface worst-case experiences, and segment by ticket type, priority, channel, and agent. Pair TTR with reopen rate — fast resolutions that get reopened aren't real resolutions. Also measure TTR in business hours rather than wall-clock to avoid weekend distortion.

What's the typical cost of improving Time to Resolution?

Cost varies by lever. Knowledge base improvements and macro libraries are low-cost and high-leverage. Adding tier-2 specialists or extending coverage hours is the biggest line item, often $60K–$120K per additional FTE fully loaded. AI-assisted triage and suggested replies sit in the middle — meaningful platform investment but typically pays back within two to three quarters via deflection and faster handle time.

What tools handle Time to Resolution tracking?

Modern help-desk and CRM platforms with built-in ticketing track TTR natively, usually with SLA timers, business-hours configuration, and segmentation dashboards. AI-assisted support platforms layer on automated triage, suggested resolutions, and aging-ticket alerts. The right category depends on volume — under 500 tickets a month, a lightweight help desk suffices; above that, you want a platform with workflow automation and analytics.

How do I implement Time to Resolution tracking for a small team?

Start by defining what 'resolved' means — typically when the customer confirms or the ticket is closed without reopening in 7 days. Configure your help desk to log open and close timestamps in business hours. Build one dashboard with median TTR by priority and ticket type, review it weekly, and pick one category to improve per quarter rather than chasing every number at once.

What's the biggest mistake teams make with Time to Resolution?

The biggest mistake is gaming the metric by closing tickets prematurely — marking issues resolved before the customer confirms, then reopening or creating a new ticket when they reply. This produces a flattering TTR number but destroys trust and corrupts the data. Always pair TTR with reopen rate and customer-confirmed resolution to keep the metric honest.

What's a good Time to Resolution benchmark?

Benchmarks vary by industry and complexity, but common targets are under 4 business hours for P1, under 24 hours for P2, and under 3 business days for P3. SaaS support teams often see overall medians of 8–16 business hours. Rather than chase external benchmarks, set internal targets tied to customer expectations and improve quarter over quarter.

Can AI reduce Time to Resolution?

Yes, meaningfully. An AI agent can triage and route tickets the moment they arrive, surface relevant knowledge base articles or past resolutions for the agent, draft replies, and auto-resolve common issues like password resets or status checks. Teams using AI-assisted support typically see 20–40% reductions in median TTR within two quarters, with the biggest gains on high-volume, low-complexity categories.
