Peter Woolley

Taught by Peter Woolley · AI tutor support included

In this video, you'll learn why internal controls matter in P3 and explore the Coso framework that underpins them. Internal controls account for 25% of the P3 syllabus, and while the board holds ultimate responsibility, the framework cascades through your organisation.

About this lesson

You'll discover how the five components of Coso—control environment, risk assessment, control activities, information and communication, and monitoring—work together to manage risk at every level. You'll also see how ethics ties directly into internal controls through Cima's ethical framework and the threats to independence (advocacy, self-review, familiarity, and self-interest). Understanding these principles helps you spot ethical risks in exam scenarios and real business situations. Beyond Coso, this video introduces the accounting and management techniques that strengthen internal controls: from traditional tools like budgeting and variance analysis to modern approaches like lifecycle costing, target costing, and lean techniques. You'll understand why focusing solely on profit isn't enough—and how frameworks like the balanced scorecard and value for money help organisations measure what actually drives performance. Finally, you'll recognise the real-world limitations of internal controls. They cost money, can only anticipate known risks, and depend on people who can make mistakes or even override them. This part sets you up for part two, where you'll dig deeper into specific control activities and how to apply them strategically.
