Background
Ericsson is moving from Waterfall towards Agile way of working. Why?
Products need to be delivered faster to the market
We want to improve quality
Cost reduction important
What does it mean for testing?
New ways of working
High demand for Test Automation
Quick iterations create new requirements on tools
Will TTCN-3 work in Agile testing?
