Big Five
The best audits have a diverse team making the best use of new team members alongside those with greater experience and a team which encourages a culture of internal challenge at the planning stage and throughout the audit. Many good audits will embrace coaching the team to develop further.
The auditor's objectives are to obtain reasonable assurance about whether the financial statements as a whole are free from material misstatement, whether due to fraud or error, and to issue an auditor's report that includes the auditor's opinion.

The objective of an audit is to form an independent opinion on the financial statements of the audited entity. The opinion includes whether the financial statements show a true and fair view, and have been properly prepared in accordance with accounting standards.
The five main stages of the audit process are Planning, Risk Assessment, Fieldwork (Execution/Testing), Reporting, and Follow-up, moving from initial engagement to ensuring corrective actions are taken to provide assurance on financial statements or processes. Auditors first plan the audit, then assess risks, perform tests (controls & substantive), report findings, and finally track implemented solutions for improvement.
The three main types of audits, focusing on who performs them, are Internal Audits (by employees for improvement), External Audits (by independent CPAs for stakeholders), and Government Audits/IRS Audits (by tax authorities). Alternatively, focusing on the purpose, they can be categorized as Financial Audits (financial statements), Compliance Audits (rules/regulations), and Operational Audits (efficiency/effectiveness).
