Which of the following is the BEST report to provide to senior management?

A daily progress report contains too much detail for senior management, who are interested in strategic overview rather than granular day-to-day activities.

A milestone report provides a concise summary of significant project accomplishments and key checkpoints reached, which is ideal for senior management. Senior management typically requires high-level information that focuses on major progress and whether the project is on track to meet its strategic objectives, without getting bogged down in daily operational details.

A quality audit is a detailed examination of quality processes and standards, primarily for the project team and quality assurance stakeholders, not typically a primary report for senior management.

A work performance report aggregates various performance data, but a milestone report specifically highlights progress against key project stages, which is often more pertinent to senior management's strategic focus than a general work performance report.
