Project Documentation refers to the collection of documents that outline the details, processes, and outcomes of a project. It serves as a guide for project teams, ensuring everyone understands their roles, responsibilities, and the project's goals. This documentation can include plans, reports, meeting notes, and other relevant materials. Effective Project Documentation helps in tracking progress, managing risks, and facilitating communication among stakeholders. It also provides a historical record that can be useful for future projects, allowing teams to learn from past experiences and improve their processes over time.
