At my job @ TWT we are currently developing a new way of checking the performance of our customers website or web application.
This is not a purely technical perspective on the site, but more a 360 degree analysis.
I will be providing more details as we get the first impressions from customer projects. Maybe you want to have your own site checked?
Until then you can find out more in our article (german) at the TWT website:
TWT entwickelt das Web Experience Lab
Stay tuned 🙂
