The project manager should consult with the project management office (PMO) for guidance on project artifacts, as the PMO is responsible for establishing and maintaining the project management standards, policies, and procedures within the organization. The PMO can advise the project manager on the best practices and requirements for archiving the project artifacts, even for a cancelled project. Archiving the project artifacts is important for capturing the lessons learned, maintaining the organizational knowledge, and complying with the legal and ethical obligations. The other options are not as effective or appropriate as consulting with the PMO. Complying with the project sponsor's request to not archive the project artifacts may result in losing valuable information and violating the professional code of conduct. Documenting the project sponsor's instructions as the archived project artifacts may not be sufficient or accurate, and may create confusion and conflict in the future. Archiving the project artifacts on the project manager's local computer may not be secure or accessible, and may not follow the organizational standards and processes.
