DevOps is one of my greatest passions. Guiding teams in the DevOps way of working, helping and facilitating them in achieving the ultimate goal of becoming a high performing team. What I often see at companies, that they’re trying to adopt the DevOps way of working with a technical approach. They often start with automation. While automation is a huge aspect of DevOps, it isn’t the key to success. Mindset and behavior is in my opinion the key to success. Getting the right culture and a facilitating governance with its processes within the company. Only then you can be successful in adopting the DevOps way of working.
