Technical Metrics Directory
A centralized repository of software engineering and IT operational benchmarks. We define the high-signal tech metrics that move infrastructure from reactive maintenance to predictive stability.
Software Delivery
Performance
These metrics focus on the velocity and stability of the software delivery pipeline. Based on industry-leading research, they identify the throughput and quality levels of modern DevOps teams.
"High-performing teams optimize for both speed and stability simultaneously."
Deployment Frequency (DF)
ThroughputMeasures how often a team successfully releases to production. This tracks the ability to deliver value in small, manageable increments.
Lead Time for Changes (LTTC)
VelocityThe duration between a code commit and its successful deployment in production. Essential for understanding cycle time efficiency.
Change Failure Rate (CFR)
StabilityThe percentage of deployments causing a failure in production that requires immediate remediation (e.g., rollback or emergency patch).
Service Reliability & Resilience
Operational health is defined by more than uptime. These data points provide a window into the user experience during system stress.
MTTR
Mean Time to Recovery. The average time it takes for the organization to recover from a product or system failure in production.
Error Budgets
The maximum amount of time a technical service is allowed to be down or perform poorly without contractual consequences.
Latency (p99)
The 99th percentile of response times. This shows the worst-case scenario experienced by the most significant users.
Codebase Health & Maintainability
Cyclomatic Complexity
A quantitative measure of the number of linearly independent paths through a program's source code. Higher complexity scores correlate with higher defect rates and increased effort for unit testing.
Technical Debt Ratio (TDR)
The ratio between the cost to fix software issues and the cost to develop them. A TDR under 5% is considered exceptional, while over 20% indicates significant systemic risk.
Documentation Coverage
The percentage of public API endpoints and critical logic paths accompanied by updated, machine-readable specifications.
Infrastructure Efficiency
Resource Utilization (RU)
Percentage of provisioned CPU/RAM actually used during peak cycles.
Cost per Transaction (CpT)
Total cloud infrastructure spend divided by total business transactions.
Waste Ratio
Aggregated cost of unattached storage, idle instances, and unused licenses.
