Definition
Management by Exception (MBE) is a principle of management in which decisions that cannot be made at one level are escalated to the next level for resolution. It involves focusing attention on significant deviations from the norm and taking corrective actions when necessary. The principle can also be applied in budgetary control, where items of income or expenditure with minor variances are ignored while significant adverse variances are addressed.
Historical Context
The concept of Management by Exception dates back to the early 20th century, influenced by Frederick W. Taylor’s principles of scientific management. It became more structured in the 1950s with the advent of management theories that emphasized efficiency and productivity.
Types/Categories
- Strategic MBE: Applied at the top management level for significant deviations impacting the organization’s strategic goals.
- Operational MBE: Used by mid-level managers to handle day-to-day operational issues.
- Financial MBE: Focuses on budgetary and financial variances.
- Project-Based MBE: Applied within project management frameworks to ensure timely intervention for project variances.
Key Events
- Early 20th Century: Introduction of scientific management principles by Frederick W. Taylor.
- 1950s: Formalization of MBE as a management principle.
- 1970s-1980s: Integration of MBE into strategic management and project management disciplines.
Detailed Explanations
Management by Exception operates on the premise that managers should focus their time and effort on significant issues that deviate from the norm rather than routine operations. This approach helps in efficient allocation of managerial resources, as only exceptional cases are escalated.
Example 1: Budgetary Control
In budgetary control, MBE would mean monitoring expenditure and income against the budget. If variances are within acceptable limits, no action is required. However, significant adverse variances trigger a detailed review and corrective action.

Importance and Applicability
MBE allows organizations to focus on critical issues, thereby improving efficiency and effectiveness. It is applicable across various sectors including manufacturing, finance, healthcare, and project management.
Examples
- Manufacturing: A production manager monitors key performance indicators and only intervenes if there is a significant drop in productivity.
- Finance: A financial manager reviews quarterly financial statements and investigates only major variances from the budget.
Considerations
- Setting Tolerances: Define acceptable variance limits to differentiate between minor and significant issues.
- Timely Reporting: Ensure that significant variances are reported promptly for timely intervention.
- Training: Equip managers with the skills to identify and address exceptions effectively.
Related Terms
- Delegation: Assigning decision-making authority to lower levels.
- Variance Analysis: Identifying differences between planned and actual performance.
- KPI (Key Performance Indicator): A measurable value that demonstrates how effectively a company is achieving key business objectives.
Comparisons
MBE vs. Delegation
While MBE focuses on exceptional cases, delegation involves passing routine tasks and decisions to lower levels.
Interesting Facts
- Historical Usage: MBE was heavily used in wartime manufacturing during World War II to streamline decision-making and improve efficiency.
- Technological Integration: Modern ERP systems incorporate MBE principles for automated alerts and reporting.
Inspirational Stories
Consider the story of Toyota, which applies MBE in its production system to achieve continuous improvement and operational excellence by empowering front-line workers to halt production for significant quality issues.
Famous Quotes
