Responsibility accounting is a system that measures the plans, actions, and results of each responsibility center. A responsibility center is a segment of an organization whose manager is accountable for specific activities.
Types of Responsibility Centers
There are typically four types of responsibility centers, each defined by the degree of control a manager has over inputs and outputs:
- Cost Center: A manager is responsible for controlling costs. Outputs are not usually measured in monetary terms. Examples include manufacturing departments, research and development, and administrative departments. Performance is often evaluated based on cost variances.
- Revenue Center: A manager is responsible for generating revenue. Costs are not usually the primary focus. Examples include sales departments or individual sales territories. Performance is often evaluated based on sales volume, market share, and customer satisfaction.
- Profit Center: A manager is responsible for both generating revenue and controlling costs, effectively responsible for achieving a target profit. Examples include individual stores in a retail chain or divisions within a company that both manufacture and sell products. Performance is evaluated based on profitability metrics like net profit, contribution margin, and return on sales.
- Investment Center: A manager is responsible for revenue, costs, and the efficient use of assets. They have control over investment decisions. Examples include large divisions or subsidiaries of a company. Performance is evaluated using metrics like return on investment (ROI), residual income, and economic value added (EVA).
Financial Measurement and Reporting
Each responsibility center receives a tailored financial report that focuses on the items the manager can control. This report compares actual results to budgeted or planned amounts, highlighting variances that require attention. The key is controllability: a manager should only be held accountable for items they can influence.
For example, a cost center report would detail controllable costs like direct materials, direct labor, and controllable overhead, comparing actual costs to budgeted amounts and calculating variances. A profit center report would show revenues, controllable costs, and resulting profit, allowing for analysis of both revenue generation and cost management. An investment center report would include profit information as well as details on invested capital, enabling the calculation of ROI or residual income.
Benefits of Responsibility Accounting
- Improved Decision Making: By delegating responsibility, managers closer to the operations can make more informed and timely decisions.
- Enhanced Performance Evaluation: Responsibility accounting provides a framework for evaluating managers based on controllable factors, fostering accountability and motivation.
- Better Resource Allocation: Identifying areas of strength and weakness allows for more efficient allocation of resources.
- Increased Efficiency: By focusing on controllable costs and revenues, responsibility accounting can lead to greater efficiency and profitability.
- Improved Communication: The process encourages communication between different levels of management and fosters a greater understanding of the organization’s overall goals.
Challenges
Implementing responsibility accounting requires a clear understanding of the organization’s structure and the relationships between different departments. Determining which costs are controllable by a specific manager can be challenging, particularly regarding allocated overhead costs. Furthermore, focusing solely on financial metrics can sometimes lead to short-term decision-making at the expense of long-term goals or ethical considerations.
