The Path to Performance

The Path to Performance

Performance is a rising requirement for building successful websites, but successful performance begins far earlier than development. So how do you get your entire team excited by it, specifically aesthetic-heavy designers?

I discuss:
* Why entire teams should care
* Everyone's role in creating and maintaining a performance budget
* How to get designers excited by performance budgets
* How to begin incorporating performance budgets into projects
