Task Success Metrics

Learn to define and measure what success means for your AI agents

How to Measure Success

Defining metrics is the first stepβ€”actually measuring them is where the work happens. You need systematic ways to collect data, calculate scores, and track trends over time. Different measurement methods work better for different metrics and contexts.

Automated Test Suites

Run predefined test cases and measure pass/fail rates

Best For:
Regression detectionContinuous validationScale testingConsistency checks
Example:

Run 1,000 test cases daily, track success rate over time

Human Evaluation

Have experts or users manually rate agent outputs

Best For:
Quality assessmentSubjective metricsEdge casesUser satisfaction
Example:

Sample 100 outputs weekly, rate on 1-5 scale for accuracy and clarity

User Feedback Collection

Gather ratings and feedback from real users

Best For:
Satisfaction trackingUX validationProblem identificationFeature requests
Example:

Thumbs up/down after each interaction, optional comment field

Production Monitoring

Track real-world metrics in live production

Best For:
Real performanceDrift detectionAnomaly identificationA/B testing
Example:

Dashboard showing success rate, latency, error rate in real-time

Interactive: Success Rate Calculator

Calculate key metrics from test results to understand agent performance:

Track Trends, Not Just Snapshots

A single success rate measurement tells you current performance. Tracking success rate over time reveals trends: are you improving? Regressing? Maintaining stability? Set up dashboards that show metrics over time, not just current values. Trends guide iteration better than snapshots.
