The Agile Manifesto is an overview of the values and principles at the heart of an Agile mindset and environment, not a guide for how to complete a project. While the manifesto does not address how to create a project plan or what that plan should entail, it does emphasize the importance of planning. The fourth value outlined in the manifesto is: “Responding to change over following a plan.”
While Agile values the importance of having and maintaining a plan, it places greater value on a team’s ability to respond to change. The project plan should be viewed as a living, breathing document that can be modified as the project requires.
