Guide: Living Documentation for PMI-ACP/BDD Exam

The core of Living Documentation lies within its name: it's a form of documentation that is continually updated, keeping it relevant and useful throughout the life cycle of the project. Unlike static documentation, living documentation evolves with the project, providing current, accurate information.

Importance:
Residing at the core of Behavior Driven Development (BDD), living documentation is crucial because it enhances communication, promotes shared understanding amongst project team members, and reduces time waste on obsolete information. It promotes clarity and prevents misinterpretation.

How it works:
Living documentation stems from acceptance tests linked to user stories or requirements. These acceptance tests are usually written in a language easily understood by all stakeholders, such as Gherkin. When acceptance tests pass, the related document is automatically updated, ensuring real-time accuracy.
