Tell me about software development methodologies.

Software development methodologies are systematic approaches to organizing the process of creating software, aimed at improving quality, manageability, and predictability of the outcome.

Main methodologies:

• Waterfall: sequential execution of phases — requirements analysis, design, implementation, testing, deployment. Suitable for projects with clearly defined requirements.

• Agile: flexible approach focused on iterative development and rapid adaptation to changes. Includes methodologies like Scrum, Kanban, etc. Allows for regular delivery of working products and quick response to feedback.

• Scrum: an Agile framework with fixed sprints (usually 2-4 weeks), daily stand-ups, roles (Product Owner, Scrum Master, team). Helps organize teamwork and task prioritization.

• Kanban: visualization of the workflow using a board, limiting work-in-progress, continuous improvement. Suitable for support and projects with unpredictable task flow.

• DevOps: integration of development and operations, automation of build, testing, and deployment. Increases the speed and quality of software releases.

The choice of methodology depends on the specifics of the project, team, and customer requirements.
