#### Editor’s note
|
| |
|
[Creating a dedicated speed team](https://calibreapp.com/blog/site-speed-improvement-framework) might be one of the first steps in a web performance journey. Your newly established team can identify areas for improvement and deliver measurable results. There’s a catch, though.
If we silo web performance work to a limited group of people, their positive impact will be short-lived. Without prioritising speed at an organisational level—setting transparent goals and spreading awareness, someone in a completely different department can undo any gains with one decision. Why? They might not know speed is a consideration.
Just like employees rally behind a company mission or values, we all need to rally behind web performance.

Lighthouse has a new API that allows testing multiple scenarios that were difficult to measure before. Now, you can test speed during interactions with the page (not only during load) with a warm cache and over time, highlighting issues that might not have shown up in lab testing before. Give it a go!
