The “C” in the CALMR approach to DevOps stands for culture, which is the foundation of successful DevOps adoption. Culture refers to the values, beliefs, and behaviors that guide the collaboration and alignment of everyone in the value stream. By creating a culture of shared responsibility, teams can manage the tensions caused by differing needs, such as speed, quality, security, and stability. A culture of shared responsibility means that everyone is accountable for the outcomes of their work, and that they work together to deliver value to the customers. It also means that teams respect each other’s roles and expertise, and seek feedback and learning opportunities. A culture of shared responsibility fosters trust, transparency, and continuous improvement, which are essential for DevOps.
