You'll want to mention several different KPIs and explain how you have used them. Make sure to provide examples from various categories, including business, product development, product quality, and product usage metrics.

"KPIs are key to tracking and measuring product positioning, growth, and success, and there are so many that can be utilized. To monitor customer movement, I like to use retention, churn, attrition, and customer lifetime value. To calculate cost basis and profitability, I look at gross margins, cost of goods sold (COGS), and operational cost of goods sold (OCOGS). Then there are other metrics to monitor, such as on-time delivery, resource availability, team velocity, testing, and even support tickets. To see how the product is selling, I review revenues, customer counts, and the sales funnel. KPIs are vital to monitoring product success, and I rely on them in making many of my decisions."
