CFR (Change Failure Rate) Metric

Definition. The CFR (Change Failure Rate) Metric measures the number of incidents worked on within a specified time window. These incidents can include: Issues from the project management (PM) provid…

Change Failure Rate (CFR): Definition and Calculation

Learn how LinearB defines and calculates Change Failure Rate, including how incidents are mapped to deployments and what data is required for accurate CFR reporting.

How LinearB Detects Releases for DORA Metrics

Understand how LinearB identifies and models releases across repositories and services. This article explains how release data is used to calculate Deployment Frequency and other DORA metrics.

Incident API – Configure Incident Detection for DORA Metrics

Configure the LinearB Incident API to ingest incidents from your incident management tools. This article explains setup, supported workflows, and best practices for ensuring incidents are accurately reflected in DORA metrics such as Change Failure Rate and MTTR.

MTTR (Mean Time to Recovery) Metric

Definition. The MTTR (Mean Time to Recovery) Metric measures the time an issue spends in the "In Progress" state. The calculation of this time depends on the issue start time strategy configured (e.g…

Mean Time to Restore (MTTR): Definition and Calculation

Understand how LinearB measures Mean Time to Restore, how recovery windows are calculated, and which incident signals are used to reflect real recovery time.

Reducing Change Failure Rate Through Smaller Deployments

Learn practical strategies for reducing Change Failure Rate by improving deployment practices, breaking work into smaller changes, and aligning coding workflows with DORA measurement principles.

Reliability & DORA Metrics

Purpose. Reliability & DORA Metrics measure production stability and recovery performance. They provide visibility into deployment frequency, change risk, and how quickly incidents are resolved. Thes…
