The document introduces the Speed of Change audit model, which guides audit processes based on the velocity of change in the organization. It describes four levels of the model - transactional, operational, functional, and strategic - that assume different degrees of correctness in outputs and objectives and require different types and depths of risk assessment and audit procedures. The document also discusses how the required auditor skills, preparation steps, outputs, and quality of the audit program vary depending on the level within the Speed of Change Model.
