To build a strong DevSecOps culture, it's essential to make developers part of the decision-making process, ensuring they're not just adopting new processes or tools but also buying into them. This collaboration is critical for success, and it's crucial to communicate the benefits of these changes to developers. Additionally, simplifying the onboarding process and learning from past experiences can help ensure that all voices are heard and that new ideas and feedback are incorporated. By formalizing a collaboration process, teams can mine collective knowledge and experience to inform tooling and processes decisions. Ultimately, cooperation between security and developer teams is at the core of any successful DevSecOps culture.
