Product Performance

Product performance is the measurement of how well a product, or any part of it, gets users to adopt it and keeps them coming back — not how fast its pages load.

The phrase carries three different meanings in three different places, which is where most confusion starts: in product analytics it means adoption, repeat use and retention of a capability; in e-commerce tools it means a sales report broken down by item; in engineering it means page speed and stability. The intended sense should be fixed before the conversation starts. Measuring the first sense means several complementary metrics side by side: the share of users who used the capability at least once, repeat use in the following period, and retention of that same group. The common error is compressing them into one composite score, because when a composite moves nobody can tell which behaviour changed.
