Culture is the first element of the CALMR approach to DevOps in SAFe. It refers to the shared mindset and values that support successful DevOps adoption. Culture in SAFe is influenced by the Lean-Agile principles and practices that guide the entire framework. Culture in DevOps requires customer-centricity, collaboration, trust, empowerment, learning, and feedback among all the stakeholders involved in the value stream. Culture also fosters a shift-left mentality, where operational and quality concerns are addressed early and often in the development process. Culture is the foundation for the other elements of CALMR: automation, lean flow, measurement, and recovery1. One of the aspects of culture is to establish a work environment of shared responsibility, where everyone in the value stream is accountable for the quality and security of the solution, and for the outcomes delivered to the customer2. This means breaking down the silos and barriers between development, operations, security, and other teams, and creating a culture of mutual trust and respect3. Shared responsibility also means that everyone in the value stream has the authority and autonomy to make decisions and take actions that support the delivery of value, while following the guardrails and policies established by the enterprise4.
