Question of 26

Q. A toy factory establishes 5% defect as permissible range and it needs not be reported to the management. However, if the defects are 6% or more than it needs to be reported to the management. Which principle of controlling is applied in the above case ? Why does the organization apply this principle ?

Concept understanding — Management By Exception

Management By Exception: The Intuition First

Imagine you are the captain of a large ship. The ship has dozens of crew members, each with their own duties. If you had to personally approve every single rope adjustment, every meal menu change, and every minor course correction, you would never have time to navigate through storms or watch for icebergs. You would drown in small decisions.

So what do good captains do? They set clear rules and boundaries. "Keep the ship within this lane. Maintain this speed range. Report to me only if something goes outside these limits." The crew handles everything that falls within the normal range. You, as captain, only step in when something deviates — when the engine temperature spikes, when the ship drifts off course, when a crew member reports a problem they cannot solve.

That is the core idea of Management By Exception.

The Precise Statement

Management By Exception (MBE) is a management practice where only significant deviations from the expected standard or plan are brought to the attention of a manager for decision-making. Routine matters and normal operations are handled by subordinates without managerial intervention.

The word "exception" here does not mean "rare" or "unusual" in the everyday sense. It means "a deviation from the norm" — something that falls outside the pre-defined acceptable range.

How It Works in Practice

Set standards first. You define what "normal" looks like. For a factory: "Produce 100 units per hour, with less than 2% defects." For a sales team: "Each salesperson should close at least 10 deals per month."
Measure actual performance. Collect data on what is actually happening.
Compare actual to standard. Find the gap.
Decide: Is this gap significant? If the gap is small (e.g., 98 units instead of 100), it falls within the acceptable range. The subordinate handles it. If the gap is large (e.g., 50 units instead of 100), it is an exception — it gets escalated to the manager.
Manager acts only on exceptions. The manager investigates the cause and takes corrective action.

Why This Matters for Exams

Important

MBE is not about ignoring problems. It is about filtering problems so that managers focus their limited time and attention on the issues that truly need their expertise.

Key points to remember:

It is a control technique — part of the controlling function of management.
It relies on pre-set standards and clear thresholds.
It delegates routine decisions downward, empowering subordinates.
It saves managerial time and prevents information overload. …

Setting a defect tolerance (5% ignored, 6%+ reported) is an application of the Critical Point Control principle, also called Management by Exception, under which only significant deviations are brought to management's attention.

Principle applied: This is the principle of Critical Point Control / Management by Exception. Under this principle, a manager does not try to control every single activity or minor deviation; instead, attention is concentrated only on Key Result Areas (KRAs) and deviations that exceed a defined acceptable range or tolerance limit — i.e., only the 'exceptions' that matter are reported upward.

Why the organisation applies this principle:

It is practically impossible and inefficient for management to monitor every small variation in every activity — doing so would be a poor use of managerial time.
By ignoring minor, tolerable deviations (here, up to 5% defects) and reporting only significant ones (6% or more), management can focus its limited time and attention on problems that genuinely require corrective action. …

$Q. Read the following statements carefully : Statement - I : Control should focus on key result areas which are critical to the success of an organization. Statement - II : Only significant deviations which go beyond the permissible limit should be brought to the notice of management. With reference to the given statements, choose the correct alternative from the following : (A) Both the statements are true. (B) Both the statements are false. (C) Statement I is true and Statement II is false. (D) Statement I is false and Statement II is true.$

Effective control systems focus on critical areas and report only significant deviations, making both statements true.

In management, the concept of control is not about micromanaging every single activity, but rather about ensuring that organizational goals are met efficiently and effectively. This requires a strategic approach to monitoring and corrective action, which is underpinned by two key principles: Critical Point Control and Management by Exception. These principles are essential because managers have limited time and resources, and they need to delegate responsibilities while maintaining accountability.

Let's break down each statement:

Analyzing Statement I: "Control should focus on key result areas which are critical to the success of an organization."

This statement describes the principle of Critical Point Control. It recognizes that not all activities or areas within an organization are equally important. Some areas, known as Key Result Areas (KRAs), have a disproportionately large impact on the organization's overall success, profitability, or strategic objectives. For example, in a manufacturing company, the quality of raw materials, production efficiency, or customer satisfaction might be KRAs.

Focusing control efforts on these critical points allows managers to allocate their attention and resources where they will have the greatest impact. Trying to control every single aspect of an operation would be inefficient, costly, and often counterproductive, leading to information overload and a loss of focus on what truly matters. Therefore, Statement I is a fundamental truth in effective management control.

Analyzing Statement II: "Only significant deviations which go beyond the permissible limit should be brought to the notice of management."

This statement articulates the principle of Management by Exception. This principle suggests that managers should only be concerned with significant deviations from planned performance or established standards. Minor variations that fall within an acceptable or "permissible limit" should be handled by subordinates at lower levels of management. …

$Q. An organization notices a continuous downward trend in product quality over the last three months but continues to produce as usual. What step in controlling is being missed?$
(a) Setting standards
(b) Measuring actual performance
(c) Taking corrective actions
(d) comparing actual performance with standards
›Reveal solutionSolution
The missing step is 'taking corrective action' — the deviation has been noticed but nothing is being done about it.

The controlling process generally involves these steps:

Setting performance standards.

Measurement of actual performance.

Comparing actual performance with standards (identifying deviations).

Analysing causes of deviation.

Taking corrective action. …
