Business Process Flow, Integrity, and Vendor Dependencies

This chapter follows how business processes are executed within information systems. The exam focus is on understanding transaction flow well enough to identify control points, processing risks, and breakdowns that affect reliability.

In This Chapter

• Core Transaction Cycles and Supporting Modules reviews the major business cycles and the system components that support them.
• Flowcharting and Business Process Diagrams explains how process visualization helps identify controls and risks.
• Evaluating Processing Integrity Controls in Major Cycles covers the controls that support accuracy, completeness, and authorization.
• Common Control Deficiencies and Mitigation Techniques highlights recurring weaknesses and practical response options.
• Third‑Party and Vendor Risk Management addresses outsourced and external-process dependencies.

How to Use This Chapter

• Read this chapter when system-process questions feel abstract.
• Focus on where errors or unauthorized activity can enter the process and what control should stop them.
• Revisit it whenever a question asks you to connect transaction flow to control effectiveness.
