User Focused Metrics

As developers for the Web, we need metrics that accurately describe the customer experience.

Up until not so long ago the Web industry looked to browser timing marks like onLoad or onContentLoaded (DOM ready), but unfortunately, these metrics only tell us how long it took to deliver assets to the browser.

We need metrics that describe what users are seeing and experiencing, without having to watch recordings of every single user session.
