The "4 Es" of auditing, particularly in the context of operational and performance auditing (often used in government and internal auditing), are Economy, Efficiency, Effectiveness, and Equity. They are used to evaluate the performance of an organization beyond just its financial compliance.
Operations audit is a separate evaluation of the outcome, output, process and input to determine whether government operations, programs and projects are effective, efficient, ethical and economical (4Es).
The concepts of economy, efficiency and effectiveness, commonly referred to as the three E's, form the basis of any performance audit.
A successful internal audit function relies on four fundamental pillars, often referred to as the “4 C's”: Competence, Confidentiality, Communication, and Collaboration. These principles guide auditors in delivering meaningful and impactful results.
2.1 The Environment as the fourth 'E'
An environmental performance audit focus would augment the traditional facets included in the existing 'three Es', through the assessment of whether appropriate consideration and due regard has been afforded to the effects resource utilisation may exert on the environment.
Although every audit is unique, the audit process usually consists of four stages: Planning, Field work, Reporting and (for some audits) Follow-up. Engagement of the client, or the area being audited, is critical at every stage of the audit process.
The SMETA 4 pillar audit is a comprehensive assessment framework designed to assess and improve a company's ethical performance and evaluate its compliance with ethical trade practices across all four key areas discussed above.
The Big 4 are the largest accounting and auditing firms in the world: Deloitte LLP (Deloitte), PricewaterhouseCoopers (PwC), Ernst & Young (EY) and Klynveld Peat Marwick Goerdeler (KPMG). They're so big that their joint revenue in 2024 was—you guessed it—$212 billion.

Pillar 4 refers to the SMETA (Sedex Members Ethical Trade Audit) 4-Pillar Audit, which expands upon the core 2-pillar audit by including environmental performance and business ethics—two critical areas for comprehensive corporate social responsibility (CSR).
4 levels of audit opinions
The 7 Es are effectiveness, efficiency, economy, excellence, ethics, equity, and ecology. They address important short-term and long-term dynamics like organizational structure, stakeholder treatment, and environmental stewardship.
1) Selecting a topic. 2) Agreeing standards of best practice (audit criteria). 3) Collecting data.
Audit Process Although every audit process is unique, the audit process is similar for most engagements and normally consists of four stages: Planning (sometimes called Survey or Preliminary Review), Fieldwork, Audit Report and Follow-up Review. Client involvement is critical at each stage of the audit process.
One of the FRC's concerns is that firms' do not maintain a consistently high standard of auditing. Whilst excellent work is performed by many, some in the same firm fall short of expectations. The engagement quality control (“EQC”) review process should ensure consistently high quality.
The Experience Economy offers four realms of experiential value to add to a business. Pine and Gilmore (1999) termed these realms, the 4Es. The 4Es consist of adding Educational, Esthetic, Escapist, and Entertainment experiences to the business.
The four common types of auditors are Internal Auditors (evaluate company operations for management), External Auditors (independent review of financial statements for outside parties), Government Auditors (ensure compliance with laws for public agencies like the IRS), and Forensic Auditors (investigate financial fraud for legal proceedings). These roles focus on different areas, from internal controls and risk management to financial reporting accuracy and fraud detection.
The 7 steps in the audit process generally cover Planning, Risk Assessment, Internal Control Testing, Fieldwork/Evidence Collection, Reporting, and Follow-Up, focusing on a systematic review from initial engagement to ensuring corrective actions are taken for operational improvement. This framework ensures comprehensive evaluation, from understanding the client's business to delivering actionable insights and ensuring accountability for identified issues.
1st, 2nd, and 3rd party audits classify audits by who performs them, differing in objectivity and purpose: a 1st Party Audit is internal self-assessment for improvement; a 2nd Party Audit is by a customer or partner on a supplier for relationship management; and a 3rd Party Audit is by an independent body for certification and public credibility.
