What KPIs do you typically use to track performance and success?

"I rely on KPIs to track and measure product growth, position, progress, and success, and I use a ton of them. A few of my favorites include retention, churn, attrition, and customer lifetime value, which help me monitor customer movement. I also regularly look at metrics like margins, gross margins, cost of goods sold (COGS), and operational cost of goods sold (OCOGS) so I can calculate cost basis and profitability. In addition, I monitor metrics like resource availability, on-time delivery, and team velocity, as well as support tickets and testing. Finally, I always watch revenues/bookings, the sales funnel, and customer counts to see how the product is selling. There are so many KPIs, and they are invaluable when it comes to monitoring the success of a product. I rely on them heavily and make many of my decisions based on them."
