Fix Rate
Definition
Fix Rate
Fix rate is the share of reported problems, defects, or faults that a team actually resolves within a defined period, measured against everything raised. It is the difference between logging problems and solving them, and the two diverge more than most reports admit.
Closure is not the same as a fix. Tickets closed as duplicate, unreproducible, or working-as-intended tidy the queue without changing anything for the person who reported the issue.
Ageing is the companion measure. A healthy fix rate alongside a growing backlog of old items means the easy work is being cleared first.
Key takeaways
- Fix rate divides problems resolved by problems raised in the same period.
- Administrative closures must be excluded, or the rate measures queue hygiene.
- Report ageing beside the rate to expose a hidden backlog of hard problems.
- Recurrence indicates symptom treatment rather than a genuine fix.
How it works
Fix rate is calculated by dividing the number of reported problems genuinely resolved during a period by the total number raised in that period, then multiplying by 100 to express the result as a percentage.
The formula is: (problems fixed ÷ problems raised) × 100.
Not every closure is a fix, and separating the categories is what makes the number trustworthy.
| Closure type | Counts as a fix? | Why |
|---|---|---|
| Root cause removed | Yes | Problem will not recur |
| Workaround applied | Partly | Track separately, revisit |
| Duplicate or invalid | No | Nothing was solved |
| Closed by ageing policy | No | Queue hygiene only |
The workaround row deserves its own column in reporting. Workarounds are legitimate short-term responses — but counting them as fixes hides a growing pile of deferred work.
Recurrence is the honest test. A defect that returns within 90 days was never fixed, whatever the closure code said.
Structured diagnosis is what separates a fix from a patch. The American Society for Quality defines root cause analysis as a collective term describing a wide range of approaches, tools, and techniques used to uncover causes of problems.
Management frameworks put improvement results on the same footing as financial ones. The U.S. National Institute of Standards and Technology publishes the Baldrige Excellence Framework, whose 2026 revision is now available after nearly 40 years of use.
Track fix rate against inflow — resolving 80 of 100 items looks strong until you notice inflow rose to 140 the following month.
The measure belongs beside the general error rate and inside the wider quality assurance reporting set rather than standing alone.
Never reward closure volume. The moment closures carry incentives, the invalid and duplicate categories start growing on their own.
Examples
Fix rates behave differently depending on who raises the problem, how reproducible it is, and whether a workaround is acceptable. Five cases show how the measure is applied.
Software teams report fix rate per release. Defects fixed against defects raised gives a release-readiness signal that a raw open count never provides.
IT service desks report fix rate with ageing bands — a 90% rate alongside items older than 60 days points straight at a deferred-complexity problem.
Manufacturers report fix rate on non-conformances. Because each item carries a root-cause record, workarounds are visible rather than buried.
Facilities teams report fix rate per building. Repeat faults at the same site usually mean an asset needs replacing rather than repairing again.
Outsourced support teams contract on fix rate with a recurrence clause. Buyers should insist that a repeat within 90 days reopens the original item rather than creating a new one.

Fix rate connects problem reporting to genuine resolution and sits inside the wider quality reporting set. The terms below cover the defect measures, the tooling, and the improvement disciplines around it.
- Error Rate: the share of work items containing a defect in the first place.
- Quality Assurance: the function that verifies whether a fix actually worked.
- Six Sigma: the methodology that targets root causes rather than symptoms.
- Business Process Improvement: the discipline that removes recurring problems permanently.
- Support Ticket: the record each reported problem is tracked against.
- Ticketing System: the tool that supplies the raised and resolved counts.
- First Contact Resolution: the front-line equivalent of resolving something properly first time.
FAQ
How is fix rate calculated?
Divide the number of problems genuinely resolved in a period by the number raised in that period, then multiply by 100.
Do workarounds count as fixes?
Partly. Track them in their own category so deferred work stays visible rather than disappearing into the headline rate.
What is a good fix rate?
It depends on inflow and complexity. Read the rate beside ageing bands and recurrence rather than against a published benchmark.
Why exclude duplicates and invalid tickets?
Because nothing was solved, and including them turns the metric into a measure of queue hygiene.
How does recurrence affect the number?
A defect returning within 90 days was never fixed, so it should reopen the original record.
Should teams be incentivised on fix rate?
Not on closure volume, because that inflates the invalid and duplicate categories immediately.
