In 2017 we set out to become 'the best and coolest DevOps team in Switzerland'. Our ambition for the next three year was, and still is, to: * reduce the number of critical incidents by 50 % every year * reduce the cost for centralised quality assurance by 60 % * reduce the amount of central leadership positions to 5 % 'We' means a team of approx 1.400 people working in software development in a large complex organisation, a leading telecommunications provider in Switzerland. This is an experience report of our continuous transformation.
