This diagram demonstrates changes made to the Secretariat's Program Activity Architecture for the 2010–11 fiscal year. What was previously the Management Policy Development and Oversight program activity was split into two separate program activities: the Management Frameworks Program Activity and the People Management Program Activity.

Similarly, what was once the Expenditure Management and Financial Oversight program activity has become two separate programs: Expenditure Management and Financial Management. The two other program activities, Internal Services and Government-wide Funds and Public Service Employer Payments, remain unchanged.
