Control Accounts
Control Accounts are specific points within the Work Breakdown Structure (WBS) where management of scope, schedule, cost, and performance of a segment of the project is integrated and controlled. They serve as management control points where the comparison of actual performance to planned performance is made. In the context of developing the WBS, control accounts are established at selected points to accumulate and analyze work performance data. Each control account is associated with one or more work packages, and each work package belongs to only one control account. This hierarchical relationship allows for efficient tracking and management of project performance at different levels. Control accounts provide a clear framework for responsibility assignment. They are often linked to organizational elements (via the Organization Breakdown Structure) to indicate who is accountable for the work and its performance. This association helps in ensuring that accountability is established for each segment of the project. One of the key benefits of control accounts is their role in Earned Value Management (EVM). They are the points where actual costs are compared to budgeted costs and earned value is calculated. By measuring the value of work performed and comparing it to the actual costs and planned value, project managers can assess cost and schedule performance. This enables proactive management, as variances can be identified early, and corrective actions can be taken to mitigate risks. Control accounts also facilitate more accurate forecasting of project costs and completion dates. By analyzing performance data at these control points, project managers can update estimates and make informed decisions about resource allocation and scheduling. In summary, control accounts are essential components in the development of the WBS, providing structured oversight of project performance. They enable integration of scope, cost, and schedule at key points, support accountability, and enhance the ability to manage the project proactively through timely analysis of performance data.
Control Accounts in Project Management: A Comprehensive Guide
What are Control Accounts?
Control accounts represent management points where scope, budget, actual cost, and schedule are integrated and compared to earned value for performance measurement. They are key elements in the Work Breakdown Structure (WBS) that serve as critical control points for project monitoring and reporting.
Why are Control Accounts Important?
Control accounts are essential because they:
• Create a structured framework for cost and schedule management
• Enable effective performance measurement at defined points
• Facilitate earned value management (EVM) implementation
• Help identify variances quickly for corrective action
• Provide management visibility at appropriate levels
• Support accountability by assigning responsibility to Control Account Managers (CAMs)
How Control Accounts Work
Control accounts function as:
1. Integration Points: They integrate scope, schedule, and budget information
2. Measurement Points: They serve as points where earned value metrics are calculated
3. Management Points: They establish where responsibility for work is assigned
4. Reporting Points: They provide the basis for performance reporting
Control accounts are typically:
• Positioned at selected management points in the WBS
• Assigned to a responsible manager (CAM)
• Comprised of one or more work packages and planning packages
• Given specific scope, schedule, and budget parameters
• Used to calculate key performance metrics (CPI, SPI, etc.)
Establishing Effective Control Accounts
To create effective control accounts:
1. Place them at appropriate WBS levels based on management needs
2. Ensure they align with organizational structure when possible
3. Assign clear responsibility to Control Account Managers
4. Define specific deliverables and acceptance criteria
5. Allocate appropriate budgets (usually in labor hours or costs)
6. Establish realistic schedules with measurable milestones
7. Implement proper earned value measurement techniques
Exam Tips: Answering Questions on Control Accounts
• Know the Definition: Memorize that control accounts are management points where scope, budget, cost, and schedule integrate with earned value
• Understand Placement: Recognize that control accounts appear at selected management points in the WBS, not at every level
• Focus on Integration: Emphasize that control accounts integrate various project elements (scope, time, cost) for performance measurement
• Highlight Responsibility: Note that control accounts are assigned to specific managers (CAMs) who are accountable for performance
• Connect to EVM: Explain how control accounts enable earned value management by providing measurement points
• Differentiate Components: Be able to distinguish between control accounts, work packages, and planning packages
• Apply Context: Consider the project size when determining the appropriate number and level of control accounts
• Watch for Relationships: Pay attention to questions about how control accounts relate to the WBS, OBS, and the responsibility assignment matrix
• Identify Benefits: Be ready to select answers that correctly identify the benefits of proper control account implementation
When faced with exam questions, remember that control accounts are fundamental to project performance measurement and serve as the cornerstone of earned value management systems.
