What are the common software development methodologies?

Common software development methodologies include agile, waterfall, Scrum, Kanban, and DevOps. Agile is an iterative approach that emphasizes flexibility and customer feedback, while waterfall is a linear, sequential process. Scrum is a framework within agile that focuses on time-boxed iterations called sprints, with specific roles and ceremonies to manage progress.

Kanban is a visual workflow management method that helps teams visualize work, limit work in progress, and optimize flow. DevOps is a methodology that integrates software development and IT operations to improve collaboration, accelerate delivery, and ensure continuous integration and deployment. Each methodology has its strengths and is chosen based on the project's specific needs, goals, and team dynamics.
