The CEO is primarily responsible for decision making and relies on the Board of Directors and subordinates for information. Auditors will question the CEO about accounting and financial reporting decisions. The COO oversees day-to-day operations and may face similar questions from auditors as the CEO. The CFO manages finances and accounting and will monitor the audit process, though most auditor questions will go to the CFO's subordinates. The controller oversees accounting, controls, and financial reporting and possesses the most timely data, developing the financial plan and monitoring progress. The controller and its staff will be most involved with the audit process.
