Tear Down This Wall! - Overcoming Collaboration Obstacles On Your DevOps Journey

Talk given by Thomas Uebel (@thomasuebel) and Sebastian Schreck (@stegschreck) at DevOpsCon 2018 in Berlin.

The discussion about DevOps is often focussing solely on the tooling aspect: automation, continuous integration & delivery; and monitoring. But automation and monitoring will only get you so far on your DevOps journey. The first and arguably hardest thing to master in DevOps is getting your work from inception into the hands of the customer fast. It requires your engineers to work hand in hand to ensure the stability of the software as well as the systems it runs on. In this talk, we will focus on the organizational aspects of DevOps: How to measure and improve your team’s effectiveness by reducing silos and silo thinking and how to get your engineers to share responsibility - a basis for every successful DevOps transformation. Thomas and Sebastian share some of the learnings made adopting DevOps at Mister Spex.
