Exam PK0-004 topic 1 question 839 discussion

The best document to reference in this scenario would be the project charter. The project charter is a document that outlines the high-level details of the project, including the project's purpose, objectives, stakeholders, deliverables, and resources. It is typically created at the beginning of the project and is used to formally authorize the project. The project charter would be the best document to reference because it would outline the initially agreed-upon deliverables that were promised to the customer. It would provide a clear reference point for the project manager to understand what was initially agreed upon and compare it to the final deliverables that were produced.
