Peter Nijenhuis
Peter Nijenhuis
S0L1D Heroes, Netherlands
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.
