KPI
A KPI (Key Performance Indicator) is a measurable metric that demonstrates how effectively a business, team, or individual is achieving key objectives and goals.
KPIs are the vital signs of a business. Just as a doctor monitors heart rate, blood pressure, and temperature, businesses monitor KPIs to understand their health and performance. The key word is 'key', not every metric is a KPI.
This is often summarized as the SMART framework. Different business functions track different KPIs. Marketing tracks cost per lead, conversion rate, and organic traffic growth.
In practice
- A SaaS company made Monthly Recurring Revenue their north star KPI, aligning marketing (leads), sales (close rate), product (retention), and support (CSAT) teams around this single metric
- A marketing team tracked 50 metrics but couldn't explain what was working, they narrowed to 5 KPIs (traffic, leads, CAC, conversion rate, revenue from marketing) and immediately identified their blog as the highest-performing channel
- An e-commerce company added 'Customer Lifetime Value' as a KPI and shifted strategy from acquiring cheap one-time buyers to investing in repeat customer programs, doubling profitability
- A startup's board required 3 KPIs per quarterly update: growth rate, retention rate, and burn rate, these three numbers told the complete story of the business's health
