The Agile Manifesto is a foundational document for agile software development, created in 2001 by a group of 17 software developers. It outlines four core values and twelve principles that guide the Agile methodology, focusing on flexible, collaborative, and iterative approaches to software development. Here’s a brief overview:
The Four Core Values
- Individuals and interactions over processes and tools: Emphasizes the importance of people and communication over rigid processes.
- Working software over comprehensive documentation: Prioritizes delivering functional software rather than extensive documentation.
- Customer collaboration over contract negotiation: Encourages ongoing collaboration with customers to meet their needs, rather than sticking to contract terms.
- Responding to change over following a plan: Advocates for flexibility and adaptability in the face of changing requirements.
The Twelve Principles of Agile
- Customer satisfaction through early and continuous delivery of valuable software.
- Welcome changing requirements, even late in development.
- 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. Give them the environment and support they need.
- Face-to-face conversation is the most efficient and effective method of conveying information.
- Working software is the primary measure of progress.
- Sustainable development, 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.
- Regularly reflect on how to become more effective, then tune and adjust behavior accordingly.
The Agile Manifesto transformed software development by promoting a more adaptive and customer-focused approach.

Agile methodology is a project management approach that emphasizes iterative development, where requirements and solutions evolve through collaboration between self-organizing cross-functional teams.
The four core values of agile methodology are:
- Individuals and interactions over processes and tools. Agile teams value the people involved in the project over the processes and tools used to complete it. They believe that strong communication and collaboration between team members are essential for success.
- Working software over comprehensive documentation. Agile teams prefer to deliver working software to users as soon as possible, even if it means that some documentation is incomplete. They believe that users can provide valuable feedback on working software, which can help to improve the product.
- Customer collaboration over contract negotiation. Agile teams work closely with customers throughout the development process to ensure that the product meets their needs. They believe that it is better to change the product based on customer feedback than to adhere to a rigid contract.
- Responding to change over following a plan. Agile teams are comfortable with change and view it as an opportunity to improve the product. They believe that it is more important to be able to adapt to change than to stick to a rigid plan.
There are many different agile methodologies, but some of the most popular include:
- Scrum: Scrum is a lightweight framework for managing agile projects. It consists of a set of roles, events, and artifacts that help teams to deliver working software on a regular basis.
- Kanban: Kanban is a visual system for managing work. It uses a kanban board to track work items as they move through a process.
- Extreme Programming (XP): XP is an agile methodology that emphasizes simplicity, automation, and testing. It is known for its use of short development cycles, pair programming, and continuous integration.
- Crystal: Crystal is a family of agile methodologies that are tailored to the specific needs of a project. There are five different types of Crystal, each with its own set of values and principles.
- Dynamic Systems Development Method (DSDM): DSDM is an agile methodology that is designed for projects that require rapid development. It emphasizes early delivery of working software, continuous user involvement, and iterative development.
Agile methodology can be a valuable approach for projects that need to be flexible and adaptable to change. It can also help to improve communication and collaboration between team members, and to deliver working software to users more quickly.
If you are considering using agile methodology for your next project, there are a few things you should keep in mind:
- Make sure your team is committed to agile principles. Agile methodology requires a lot of collaboration and communication, so it is important that your team is willing to work in this way.
- Choose the right agile methodology for your project. There are many different agile methodologies, so it is important to choose one that is appropriate for the size and complexity of your project.
- Be prepared to adapt to change. Agile methodology is all about responding to change, so be prepared to adjust your plans as needed.
- Measure your progress. It is important to track your progress and make sure that you are meeting your goals.
If you are willing to put in the effort, agile methodology can be a very rewarding approach to project management.
