I recently attended the 2017 Click Summit conference produced by Brooks Bell. It was a fantastic event where testing and optimization experts came together to learn, share and connect. I was able to participate in four different panel discussions to engage and hear from the testing community. Two themes grabbed my attention: Single Page Apps and the Build vs Buy paradox. In this two-part series, I will explore both of these topics and discuss how they impact the customer experience through testing and optimization. Let's start with Single Page Apps or SPAs.
