Concept of controlling
Controlling means making sure that work is done as planned. The manager sets a standard (the target), checks the actual result, finds the gap (called a deviation) and takes steps to fix it.
Features
- It is goal-oriented: it keeps the firm on track to its goals.
- It is a continuous process: checking never stops.
- It is a pervasive function: every manager at every level does it, in every type of firm.
- It is both backward-looking (checks past work) and forward-looking (improves future work).
Importance of controlling
- Helps reach goals: it keeps work on the right path and warns early if things go wrong.
- Judges the accuracy of standards: if everyone misses the target, maybe the target itself is wrong.
- Makes good use of resources: it cuts waste of money, material and time.
- Improves employee motivation: people know what is expected and on what basis they will be judged.
- Ensures order and discipline: close checking reduces dishonest and careless behaviour.
- Helps coordination: all departments work to the same standards.
Relationship between planning and controlling
Planning and controlling are closely linked.
- Planning comes first. It sets the goals and standards. Without a plan, there is nothing to check against.
- Controlling follows. It checks whether the plan is working. Without control, a plan is only a hope.
- Planning is looking ahead (prescriptive). Controlling looks back (evaluates past work) and ahead (its lessons improve the next plan).
- So we say: planning without controlling is meaningless, and controlling without planning is blind.
Think of a loop: plan โ do โ check โ correct โ better plan.
Steps in the controlling process
- Setting performance standards: clear targets. Quantitative (in numbers: cost per unit, units per day, sales in rupees) or qualitative (in words: good image, polite service). Numbers are easier to check.
- Measuring actual performance: through counting, sample checks, personal observation and reports. Measure in the same units as the standard.
- Comparing actual with standard: this shows the deviation. Deviation = actual โ standard.
- Analysing deviations: not every gap needs action. Two useful ideas:
- Critical point control: watch only the key result areas (KRAs) that affect the whole firm, e.g. a 5% rise in labour cost matters more than a 20% rise in stationery cost.
- Management by exception: act only on big deviations beyond a set limit; small ones inside the limit are left alone. This saves the manager's time.
- Taking corrective action: fix the cause. Examples: train workers, repair or replace machines, improve materials, change the method, or revise the standard if it was unrealistic.
Key formulas and definitions
- Deviation = Actual performance โ Standard performance.
- Deviation % = (Actual โ Standard) รท Standard ร 100.
- Steps: set standards โ measure โ compare โ analyse deviations โ corrective action.
- Critical point control: watch key result areas only.
- Management by exception: act only on deviations beyond the set limit.
- Planning sets standards; controlling checks them.
Worked examples
1. Standard output is 500 units a day. Actual output is 450. Find the deviation and deviation %.
Deviation = 450 โ 500 = โ50 units. Deviation % = โ50 รท 500 ร 100 = โ10%.
2. Standard cost is โน20 per unit. Actual cost is โน23 per unit. Is this positive or negative for the firm? Find the %.
Deviation = 23 โ 20 = โน3 more per unit, which is bad for the firm (cost is higher). % = 3 รท 20 ร 100 = 15% above standard.
3. A firm allows ยฑ5% deviation. Sales target โน10,00,000; actual โน9,60,000. Should the manager act?
Deviation = โ40,000, which is โ4%. It is inside the ยฑ5% limit, so under management by exception the manager does not need to act.
4. In a car factory, the cost of cleaning supplies rose 20% and the cost of steel rose 4%. Which needs more attention?
Steel. It is a key result area and a large part of total cost. This is critical point control.
5. Actual output is below standard because a machine is old and breaks often. Name the step and the action.
Step 4 found the cause (faulty machine). Step 5, corrective action: repair or replace the machine.
6. Every worker in a unit misses the target of 200 pieces a day, even the best ones. What should the manager suspect?
The standard itself may be unrealistic. Controlling helps judge the accuracy of standards, so the target may need to be revised.
Common mistakes
- Thinking controlling means strict punishment. It means checking and correcting, not blaming.
- Thinking every deviation needs action. Management by exception says act only on big ones.
- Saying controlling only looks back. It also looks forward by improving future plans.
- Forgetting that planning must come first. Without standards there is nothing to control.
