Exam IIA-CIA-Part2 Topic 8 Question 133 Discussion

An The top-down approach to understanding business processes is conducted from a broad organizational perspective, beginning with the overall objectives and strategic goals of the organization and then drilling down into the specific processes that support these goals. While this approach ensures alignment with the organization's objectives, it has the greatest risk of overlooking critical processes at the lower levels, especially those that might be operationally significant but not directly linked to top-level objectives.
IIA Reference:
IIA Standard 2010: Planning suggests that internal auditors should understand the organization's business processes in relation to its objectives. The top-down approach aligns with this but can risk missing important operational details that might be captured through a more granular (e.g., bottom-up) approach.
