What term is used for a collaborative approach to software delivery involving various teams?

The term that is used for a collaborative approach to software delivery involving various teams is DevOps. DevOps is a cultural and technical movement that emphasizes collaboration between software development (Dev) and IT operations (Ops) teams. Its primary goal is to shorten the development lifecycle while delivering features, fixes, and updates frequently in close alignment with business objectives.

In a DevOps environment, practices such as continuous integration, continuous delivery, and automation of the deployment process become integral. This facilitates not only more robust software development but also enhances the communication and collaboration among cross-functional teams, leading to improved efficiency and faster delivery times.

While Agile, Scrum, and Waterfall are related to software development methodologies, they do not specifically encapsulate the collaborative approach across diverse teams that DevOps promotes. Agile focuses on iterative development and responsiveness to change, Scrum is a framework for managing Agile projects, and Waterfall represents a more traditional linear approach to software development. Each of these methodologies may incorporate elements of collaboration, but they do not embody the full cultural shift towards integrated operations that DevOps does.
