#### Editor’s note
 
Any work requires focus and prioritisation. It’s challenging to be productive and feel like we’re making an impact when we’re overwhelmed by competing tasks that all *seem* important.
 
This is also true when improving speed. Our success in building inclusive and fast experiences relies on many factors, including identifying what’s both feasible and impactful.
 
We need a strategy. What are our goals? What’s possible to achieve? How hard is it going to be? The more intentional we are, the more likely we are to see results.
