Prerequisite Knowledge

Familiarity with real user measurement and some JavaScript expertise.


You’ve seen it before: The blank stares, crossed arms, and furtive glances at cell phones. The creative who doesn’t understand why their 3MB banner image is driving away mobile users. The product manager who doesn’t think four different versions of JQuery on the site is all that bad. The VP who can’t be bothered about page load times because of unclear ROI.

Why won’t these people listen? Because they don’t speak our language and, too often, we don’t speak theirs either. In this talk, we will explore ways to analyze and present performance data in ways that people outside of the Velocity tribe can understand and act on. We will look at specific approaches such as:

  • Combining speed measurements with behavioral measurements to see how delays impact human behavior.
  • Estimating the return on investment of a given performance improvement.
  • Leveraging an organization’s natural competitive nature to motivate them to act.

At the end of this talk you will have several new ideas of ways to persuade your colleagues to make changes to their site’s performance, with case studies to back up your argument.
