Good goals are a composition of four specific kinds of numbers: A target states where you want to reach. A baseline identifies where you are today. A trend describes the current velocity. A time frame sets bounds for the change. Put these all together, and a well-structured goal takes the form of: “In Q3, we will reduce time to render our frontpage from 600ms (p95) to 300ms (p95). In Q2, render time increased from 500ms to 600ms.”
