What is Agile software development?

1. Prioritize customer satisfaction through early and continuous delivery of valuable software
2. Acceptance of changes in requirements, even at a late stage of development
3. Frequent delivery of working software (from several weeks to several months)
4. Close, day-to-day cooperation between business and developers
5. Building projects around motivated individuals and providing them with the right environment
6. Direct face-to-face communication as the best form of conveying information
7. Working software as the primary measure of progress
8. Promoting sustainability and pace of work
9. Continuous focus on technical excellence and good design
10. Simplicity – the art of maximizing the amount of work not done
11. Self-organized teams
12. Regular adaptation to changing circumstances

1. Planning: Identify goals and priorities for a given iteration
2. Design: Create solutions for planned functionality
3. Development: Implementation of planned features
4. Testing: Verification of quality and compliance with requirements
5. Overview: Presentation of results to stakeholders and collection of feedback
6. Retrospective: analyze the process and identify areas for improvement

This process is repeated in each iteration, allowing for continuous product and process improvement.

• It is self-organized and multidisciplinary
• Takes responsibility for delivering product increments
• Works directly with the customer and other stakeholders
• Actively participates in planning and estimating tasks
• Regularly deliver working software
• Adapts to changing requirements

1. Increased flexibility and adaptability to change
2. Deliver business value faster
3. Better product quality through continuous testing and improvement
4. Increased customer satisfaction through frequent delivery and collection of feedback
5. Better communication and cooperation in the team
6. Increased design transparency
7. Reducing project risks

1. Change in organizational culture and team mentality
2. Difficulties in estimation and long-term planning
3. Need for ongoing customer engagement
4. Managing stakeholder expectations
5. Integration with existing processes and systems
6. Ensure proper documentation in a dynamic environment
7. Scaling Agile in large organizations

1. Project management systems: JIRA, Trello, Asana
2. Version control tools: Git, SVN
3. Continuous integration and delivery tools: Jenkins, GitLab CI
4. Test automation tools: Selenium, JUnit
5. Team communication tools: Slack, Microsoft Teams
6. Work visualization tools: Kanban boards, burndown charts

• Flexibility vs rigid planning
• Iterative delivery vs. delivery at the end of the project
• Continuous customer interaction vs limited interaction
• Adaptation to change vs resistance to change
• Self-organized teams vs hierarchical structures

1. Programming in pairs
2. Test-Driven Development (TDD)
3. Continuous Integration/Continuous Delivery (CI/CD).
4. Code refactoring
5. User Stories as a form of requirements definition
6. Daily Stand-ups
7. Sprint Reviews and Retrospectives

1. Velocity – the amount of work done in a sprint
2. Burn-down and burn-up charts
3. Cumulative Flow Diagram
4. Lead Time and Cycle Time
5. Customer satisfaction index
6. Code quality and number of defects

• Regularly provides feedback
• Participates in sprint planning and reviews
• Prioritizes functionality
• Is available to the team to clarify requirements
• Accepts product increments

• Automation of CI/CD processes
• Implementing Infrastructure as Code practices
• Monitor and respond quickly to problems in the production environment
• Fostering a culture of collaboration between development and operations teams

In summary, Agile software development is an approach that allows for flexible and efficient software development in a dynamic business environment. With its focus on collaboration, adaptation to change and continuous value delivery, Agile has become the dominant paradigm in modern software development.
