What is Agile Software Development?
Agile software development is an approach to creating software that emphasizes flexibility, collaboration, and customer satisfaction.
In Agile, development teams work in short iterations or cycles, typically two to four weeks long, called sprints. During each sprint, the group focuses on building and delivering a small, functional piece of the software.
Let us dive in to understand agile software development.
What is Agile Software Development?
Agile software development is a methodology for software development that emphasizes flexibility and collaboration. It prioritizes delivering minor, incremental improvements to a software product over a short period rather than trying to deliver a complete product all at once.
The Agile approach values customer collaboration, responding to change, and providing working software frequently. It is based on the Agile Manifesto, which outlines 12 principles for software development that prioritize collaboration, customer satisfaction, and flexibility over processes and tools.
The most popular Agile methodologies include Scrum, Kanban, and Lean.
Key Features of Agile Software Development

Next let us read about Agile Software Development Cycle.
What Is Agile Software Development Life Cycle?
The Agile software development process, also known as an iteration or sprint, typically follows these steps:
Planning: The team determines what features or components of the software they want to build during the upcoming iteration.
Design and development: The team designs and builds the software, following Agile principles such as customer collaboration and working software as the primary measure of progress.
Testing: The team tests the software to ensure it meets the agreed-upon requirements and specifications.
Review and demo: The team demonstrates the newly built software to stakeholders and receives feedback.
Retrospective: The team reflects on the iteration, identifying what worked well and what can be improved for the next iteration.
Repeat: The cycle then repeats, with the team using the feedback from the review and demo to plan and build the next iteration of the software.
This cycle is repeated until the software is fully functional and meets customer or end-user needs. Focusing on frequent, small deliveries allows the team to quickly respond to changes in requirements or direction and to ensure that the built software is high quality and meets the customer’s needs.
What Are The Values And Principles Of The Agile Manifesto?
The Agile Manifesto outlines four values and twelve principles for software development:
Values:
- Individuals and interactions over processes and tools
- Working software over comprehensive documentation
- Customer collaboration over contract negotiation
- Responding to change by following a plan
Principles:
- Our highest priority is to satisfy the customer through the early and continuous delivery of valuable software.
- Welcome change, even late in development. Agile processes harness change for the customer’s competitive advantage.
- Deliver working software frequently, with a preference for shorter timescales.
- Business people and developers must work together daily throughout the project.
- Build projects around motivated individuals.
- The most efficient and effective method of conveying information to and within a development team is by face-to-face conversation.
- Working software is the primary measure of progress.
- Agile processes promote sustainable development. The sponsors, developers, and users should be able to maintain a constant pace indefinitely.
- Continuous attention to technical excellence and good design enhances agility.
- Simplicity–the art of maximizing the amount of work not done–is essential.
- The best architectures, requirements, and designs emerge from self-organizing teams.
- The team regularly reflects on how to become more effective, then tunes and adjusts its behavior accordingly.
