Guide on Definition of Done

Definition of Done refers to the set of criteria that must be met before a task or feature is considered completed. These criteria usually include certain tests passing, code being reviewed and the feature being deployed to the development environment.

Importance: The Definition of Done is important because it ensures that everyone on the team has the same understanding about when a task is finished. Without it, some team members might consider a task done as soon as it's coded, while others might not consider it done until it's been tested and deployed.

How It Works: The Definition of Done is typically defined at the start of a project. It is then referenced whenever a task is being moved to 'done' on the task board. If it meets all the criteria, then it's checked off as done.
