Quality Assurance industry keeps changing very fast. Sometimes back it was a standard to use Waterfall, gate keepers of the quality were large QA departments and it took months to deliver software to customers.

It worked well for some companies but it failed badly for others. The talk is about the way how we overcame some of the challenges in Mobile software development and quality - testing on right level, risk-based testing, mobile test automation and QE processes.
