Engineering & Reliability KPIs

Engineering and reliability metrics measure the performance of software delivery teams and the operational health of the systems they build. The DORA metrics (Deployment Frequency, Lead Time for Changes, Change Failure Rate, MTTR) provide a research-validated framework for measuring both throughput and stability, while infrastructure cost, error rate, and uptime metrics reflect the platform quality that customers experience directly.

All Engineering & Reliability Metrics Definitions (10 KPIs)

Each entry includes formula, platforms, causal drivers, benchmarks, and Q&A.

System Uptime / Availability
SLA%
System Uptime (or Availability) measures the percentage of time a service is operational and accessible to users, typically expressed as a percentage of total time in a given period.
CTO VP Engineering Director Engineering COO
API Latency / Response Time
P95
API Latency measures the time elapsed between a client sending a request to an API and receiving a complete response.
CTO VP Engineering Director Engineering
Deployment Frequency
Deployment Frequency measures how often an organization successfully deploys code to production.
CTO VP Engineering Director Engineering
Mean Time to Recovery
MTTR
Mean Time to Recovery (MTTR) measures the average time required to restore a service or system to normal operation after a failure or incident.
CTO VP Engineering Director Engineering COO
Change Failure Rate
CFR
Change Failure Rate (CFR) measures the percentage of deployments or changes to production that result in a service degradation, incident, or rollback.
CTO VP Engineering Director Engineering
Code Coverage
Code Coverage measures the percentage of application code executed by automated tests in the test suite.
VP Engineering Director Engineering CTO
Technical Debt Ratio
Technical Debt Ratio measures the estimated remediation cost of code quality issues relative to the total cost of developing the codebase, expressed as a percentage.
CTO VP Engineering Director Engineering
Infrastructure Cost Per User
Infrastructure Cost Per User measures the average monthly cloud infrastructure spend required to serve each active user, enabling teams to track whether infrastructure costs are scaling efficiently as the user base grows.
CTO VP Engineering CFO
Error Rate
Error Rate measures the percentage of API requests, user sessions, or transactions that result in an error (typically HTTP 5xx server errors or application-level exceptions).
VP Engineering Director Engineering CTO
Lead Time for Changes
LTFC
Lead Time for Changes measures the elapsed time from when a code commit is made to when that change is running in production.
