Educating the team on the many topics of website performance is one of the best investments you can do. We highly recommend to involve all individuals who work on your online presence. Only when the whole team understand the topic to it’s full extend, it will lead to your optimal, desired results.
We believe it starts with creating a general awareness on the ROI it can make, but beyond that it is important that every discipline is educated on the specific stuff related to his or her responsibility. Our Start guide on Performance can help here.
Beyond this website, there is not much published about Web Performance Optimization (WPO) in a structured, unbiased way. There are a few books (available on amazon), of which mainly the books from Steve Soulders are highly recommended.
