Building Your Measurement Strategy

Start with basic metrics and gradually build a comprehensive measurement program that demonstrates clear value.

Define Success Metrics

Choose 3-5 key metrics that align with your organization's goals and are easy to track.

Set Up Tracking

Implement measurement tools and establish baselines before making changes.

Create Regular Reports

Establish reporting cadence and formats that work for different stakeholder groups.

Act on Insights

Use data to make informed decisions about priorities, resources, and improvements.

Measurement Pitfalls

Vanity metrics: Focus on metrics that drive decisions, not just impressive numbers.

Over-measurement: Too many metrics can overwhelm and distract from what matters.

Ignoring context: Always consider external factors that might influence your metrics.

Signs of Measurement Success

You'll know your measurement strategy is working when: Stakeholders regularly reference your metrics, decisions are data-driven, you can predict and prevent problems, and you have clear evidence of your design system's value.
