Chapter 8 Controlling
Chapter 4 decided what the firm would achieve. Chapters 5, 6 and 7 built the
structure, filled it with people and set them working. Controlling asks the one question nobody
has yet asked: did any of it actually happen? — and then feeds the answer straight back
into the next plan.
Where we were
From Chapter 7 — Directing
Chapter 7 set the organisation in motion. Supervision, motivation, leadership and
communication turn a chart on paper
into people doing work today. Controlling asks the one question left:
is it going where Chapter 4's plan said it would?
The shape of Part A
Plan → organise → staff → direct → control. Four chapters have pushed work
outwards from the manager's desk. This one is the only chapter that brings information
back — and it is the reason the five functions are a cycle and not a queue.
Chapter 8 is the last chapter of Part A. When we close it, the whole
management process closes with it.
Where we are going
Meaning of controllingNeither "checking" nor "restricting"FeaturesImportance — six pointsLimitations — four pointsPlanning ⇄ controllingThe five-step processPerformance standardsMeasurementDeviationCritical point controlManagement by exceptionCorrective actionThe management cycle closes
Three ideas carry almost every mark in this unit: the
six importances, the planning–controlling relationship, and the five steps.
Everything else on this slide hangs off one of those three.
Two wrong readings of the word
Students routinely write…
"Controlling means checking the work of employees." · "Controlling means
restricting employees so that they do not do anything wrong."
Why "only checking" is wrong
Checking is step 2 and step 3 of a five-step process. A manager who measures and
compares but never analyses the deviation or takes corrective action has not
controlled anything — he has only collected numbers.
Why "restricting" is wrong
Control is not aimed at the employee; it is aimed at the deviation. Standards are
told to employees in advance, which is exactly why controlling
improves motivation rather than
crushing it.
Say it this way instead
Controlling is ensuring that activities conform to the plans. Every word of the
definition points backwards at Chapter 4 — not sideways at the employee.
Controlling — the definition
Definition
Controlling means ensuring that the activities in an
organisation are performed as per the plans. It also ensures that the organisation's
resources are being used effectively and efficiently for the achievement of
predetermined goals.
The quotable definition — Koontz and O'Donnell
"Managerial control implies the measurement of accomplishment against the standard
and the correction of deviations to assure attainment of objectives according to
plans."
Three words to bank
standard · deviation · corrective
action. Any definition of controlling that omits all three is incomplete, and any answer
that carries all three earns the mark even if the sentence is clumsy.
Four features of controlling
1 · Goal-oriented
It exists only to see that predetermined organisational goals are achieved. Remove
the goal and there is nothing to control against.
2 · Pervasive
Performed at all levels
and in every kind of organisation — a school, an army unit, a hospital, a club, a
steel shop.
3 · Continuous
Not an annual audit. It runs alongside performance — gas levels in a plant are
monitored every minute, not once a year.
4 · Both backward- and forward-looking
Backward, because it examines what has already happened; forward, because the corrective
action it produces shapes the next plan.
Not the last function
Controlling is not the last function of management. It completes one cycle of
the management process and brings the cycle back to planning.
Why is controlling not simply "the last function of management"?
It is listed fifth, so calling it "last" feels harmless — and that is exactly why students
lose the mark. "Last" implies the process stops there. It does not. The deviations that
controlling discovers, and the causes it identifies, become the premises of the next
plan. That is why the NCERT text says controlling "brings the management cycle back to the
planning function".
Write it as: "Controlling is the last step of one cycle of the management process,
but not the last function — it feeds back into planning and begins the next cycle."
That sentence earns the mark that "it is the last function" throws away.
A useful test: if controlling were genuinely last, a firm would plan once and
control forever. No firm does. Chapter 4's plan for next year is written out of Chapter 8's
deviation report for this year.
Controlling on a shop floor
Case 1 · Chhattisgarh Fab Works, Bhilai
Rakesh Verma fabricates structural steel for a Bhilai plant. His
order book says 1,200 tonnes a month at a reject rate of 2%. Every Saturday he pulls the
weighbridge slips and the inspection register. In the third week of June the
register showed 268 tonnes despatched against a weekly target of 300, and rejects at 4.6%
against the permitted 2%. He walked to the welding bay the same afternoon, found two
machines running on a worn electrode grade, and had them changed by Monday.
Question 1 3 marks
Identify the function of management Rakesh is performing, and state the three elements of
it visible in the case.
Are you ready for the answer? 🤔
Answer
A 3-mark question wants 3 points. Points ≈ marks — this is the rule for
every answer in this subject, and it starts here.
ControllingRakesh is ensuring that activities conform to the plan —
the standard of 300 tonnes a week at 2% rejects.
Measurement and comparisonThe weighbridge slips and the inspection
register are the measurement of actual performance, compared week by week against the
standard.
Corrective actionChanging the electrode grade is the
corrective action that removes the cause of the deviation.
"In the third week of June the register showed 268 tonnes despatched
against a weekly target of 300, and rejects at 4.6% against the permitted 2%."
Write the definition for marks
Question 2 1 mark
State the meaning of controlling.
Are you ready for the answer? 🤔
Answer
Controlling means ensuring that the activities in an organisation are performed as per
the plans — it is the measurement of actual performance against the
standard and the correction of deviations.
A 1-mark answer is one sentence, not a list. But it must still contain
the examiner's words: as per the plans, standards, deviations.
★ Challenge — is this controlling at all?
★ Challenge 4 marks
A Mysuru soap factory installs CCTV cameras over every packing line. The owner watches the
footage each evening but has never written down a packing target, and has never told the
packers what output is expected of them. A student writes: "This is controlling, because the
owner is checking the work." Is the student right? Justify.
Are you ready for the answer? 🤔
Answer
The student is wrongWatching is not controlling. Controlling is a
five-step process, and the owner has skipped the first step.
No standard, therefore nothing to controlControlling
is blind without planning — if no packing target was ever set, there is no benchmark
against which the footage can be judged.
No deviation can be computedA deviation is the difference
between actual performance and the standard. With no standard, the difference is undefined.
What it is insteadIt is mere observation — and, because the
packers were never told what is expected of them, it will be read by them as
restriction, producing exactly the resistance that is one of controlling's
limitations.
A 4-mark question wants 4 points. Notice that each point is a bolded
heading plus one line — never a paragraph.
Importance of controlling — the six
This is the most-asked 5- or 6-mark question in the unit. Learn the six
headings first; the explanations follow easily.
It measures progress towards the goal, brings deviations to light and indicates
corrective action — keeping the organisation on the right track.
2 · Judging accuracy of standards
A good control system lets management verify whether the standards themselves are
accurate and objective, and revise them as the environment changes.
3 · Making efficient use of resources
Every activity is performed in accordance with predetermined norms, which reduces
wastage and spoilage.
4 · Improving employee motivation
Employees know in advance what is expected of them and on what basis they will be
appraised — which motivates
better performance.
5 · Ensuring order and discipline
A close check on activities minimises dishonest behaviour and creates an atmosphere
of order and discipline.
6 · Facilitating coordination in action
Every department and employee is governed by predetermined standards that are
coordinated with one another, so
all effort pulls one way.
Why is "judging accuracy of standards" a benefit of controlling, when the standard came from planning?
This is the subtlest of the six, and the one most often left out. The other five are about
the performance; this one is about the plan. Controlling is the only function
that puts the plan in contact with reality, so it is the only function that can report back
that the plan was wrong.
If a Tiruppur unit misses a 300-piece daily target for eleven weeks running, and the workers,
the machines and the fabric are all sound, the honest conclusion is not "the workers are
underperforming" — it is "300 was never achievable". That finding is manufactured by
the control system and consumed by the next plan. It is the cleanest single proof that
controlling is forward-looking.
In the paper this point is worded: "An efficient control system keeps a
careful check on the changes taking place in the organisation and in the environment, and helps
to review and revise the standards in the light of such changes."
The six, seen in one firm
Case 2 · Kongu Knitwear, Tiruppur
Lakshmi Sundaram exports knitted T-shirts to a European buyer. Since
installing a daily line-wise output board and a fortnightly fabric-wastage report, three things
have changed. Cutting waste fell from 9% to 5.5%, worth about ₹14 lakh a year.
Each of the four lines now knows its daily target before the shift begins, and
the two lines that beat it are named on the board. And the dyeing, cutting and packing
sections, which used to blame one another for delays, now work to targets that are set from the
same shipping date.
Question 3 4 marks
Identify and explain the four points of importance of controlling illustrated in the
case above.
Are you ready for the answer? 🤔
Answer
Making efficient use of resourcesFabric wastage falling from 9% to
5.5% is a direct reduction of wastage and spoilage.
Improving employee motivationThe lines know their target
in advance and are recognised for beating it — the standard is a motivator, not a
threat.
Facilitating coordination in actionDyeing, cutting and packing now
work to standards derived from one shipping date, so the departments' efforts are
coordinated.
Accomplishing organisational goalsThe export delivery date is the
organisational goal, and every one of these standards is set backwards from it.
"Each of the four lines now knows its daily target before the shift
begins, and the two lines that beat it are named on the board."
Two of these four could be argued in either order. What cannot be argued is
the form: heading, one line, quoted proof.
The 6-mark version
Question 4 6 marks
"Without control, the best of plans can go awry." Explain the importance of controlling in
an organisation.
Are you ready for the answer? 🤔
Answer
A 6-mark question wants 5 or 6 points — and this one has exactly six
available, which is why it is set so often. Six short headed points beat four long ones every
time: the examiner is counting headings, not lines.
Accomplishing organisational goalsIt measures progress, reveals
deviations and indicates corrective action, keeping the organisation on track.
Judging accuracy of standardsIt verifies whether the standards set
are accurate and objective, and helps revise them as conditions change.
Making efficient use of resourcesWork performed to predetermined
norms reduces wastage and spoilage.
Improving employee motivationEmployees know in advance what is
expected and how they will be appraised, which improves performance.
Ensuring order and disciplineA close check minimises
dishonest behaviour and creates an atmosphere of order.
Facilitating coordination in actionPredetermined, mutually
consistent standards make every department pull towards the same objective.
★ Challenge — control that destroyed motivation
★ Challenge 4 marks
Two Delhi logistics firms fit the same GPS trackers to their trucks. In Firm A, drivers were
told the acceptable idling limit in advance and are paid a monthly bonus for staying inside it;
idling fell 30%. In Firm B, drivers were told nothing, and six of thirty resigned within two
months. The control technology is identical. Explain, using the importance and the
limitations of controlling, why the outcomes differ.
Are you ready for the answer? 🤔
Answer
The standard must be communicated in advanceControlling
improves employee motivation only when employees know beforehand what is expected and
on what basis they will be judged. Firm A did this; Firm B did not.
Firm B triggered resistance from employeesAn unannounced watch is
read as a restriction on freedom — one of the four recognised
limitations of controlling.
Firm A linked the standard to an incentiveA financial
incentive attached to the
standard turns the control system into a motivator, which is Chapter 7 doing Chapter 8's
work.
The lessonA control system is not a device; it is a
process. Fitting the instrument is step 2. Without step 1 — the communicated
standard — the instrument only produces resentment.
Limitations of controlling — the four
1 · Difficulty in setting quantitative standards
The system loses effectiveness where standards cannot be stated in numbers —
employee morale, job satisfaction, human behaviour. Comparison then becomes a matter
of opinion.
2 · Little control over external factors
An enterprise cannot control government policy, technological change or
competition — Chapter 3's
environment is a given, not a variable.
3 · Resistance from employees
Control is often resisted as a restriction on freedom — employees object to being
kept under strict watch, for example by CCTV.
4 · Costly affair
It involves expenditure, time and effort. The cost of the control system must not
exceed the benefit derived from it — which is why a small firm cannot justify an
elaborate one.
HookDifficult standards · Little external control ·
Resistance · Costly — "Difficult Limits Raise Costs"
A phrasing worth memorising
For limitation 4 the examiner wants the trade-off stated, not just the word "costly":
"Managers must ensure that the cost of installing and operating a control system does not
exceed the benefits derived from it."
A limitation is not a verdict
Students write "controlling has limitations, therefore it is not important." Both lists are
examinable and both are true at once — and the board often asks them in the same
question: "Explain the importance of controlling. What problems are faced in
implementing an effective control system?" That is a 6-mark question with two
halves, not one.
When the standard cannot be a number
Case 3 · Chamundi Soaps, Mysuru
Vasanthi Rao makes sandalwood soap for a heritage retail chain. Her
production standards are exact — 4,000 cakes a shift, moisture below 12%. Her problem is the
quality room. The plan says the perfumers must "maintain the traditional
fragrance profile", and last month two batches were passed by one perfumer and rejected by
another with no way of saying which was right. She has also just been told that the
imported fixative she uses now attracts a higher customs duty, which will push her cost per
cake ₹1.40 above the standard she set in April.
Question 5 3 marks
Identify the two limitations of controlling Vasanthi is facing, and state which of the two
she can do something about.
Are you ready for the answer? 🤔
Answer
Difficulty in setting quantitative standards"Maintain the
traditional fragrance profile" cannot be measured, so two perfumers reach opposite verdicts
on the same batch.
Little control over external factorsA change in customs
duty is a decision of government — part of the firm's environment, which no control
system can correct.
Which one she can act onOnly the first. She can define the
qualitative standard in measurable proxies — a fixed fixative percentage, a panel score out
of ten, a maximum permitted variation against a retained reference cake. The duty she can
only revise the standard for.
"The plan says the perfumers must 'maintain the traditional fragrance
profile', and last month two batches were passed by one perfumer and rejected by another with
no way of saying which was right."
★ Challenge — a limitation, or bad practice?
★ Challenge 4 marks
A Bhilai fabricator abandons his weekly inspection register, saying: "Controlling is a
costly affair and my unit is small — the limitation applies to me." His register costs one
clerk four hours a week; the rejects it catches are worth ₹3 lakh a year. Is he correctly
applying the limitation? Answer in four points.
Are you ready for the answer? 🤔
Answer
He has misread the limitationThe limitation is not "control is
expensive"; it is that the cost must not exceed the benefit. Here the cost is four
clerk-hours and the benefit ₹3 lakh.
The test is a comparison, not a sizeSmall firms are named in the
textbook only because an elaborate system cannot be justified on a small turnover — not
because a small firm should not control at all.
What he losesWithout the register he loses step 2 —
measurement of actual performance — and therefore the whole process; every later step
depends on it.
The right decisionKeep the register; simplify it. Apply
critical point control — inspect the two operations that generate
most of the rejects, rather than every operation.
The keyword in the last point is taught three slides from now. If the class
cannot supply it yet, that is the point of putting it here.
The inseparable twins
The sentence the paper wants
Planning and controlling are the
inseparable twins of management. Planning without controlling is
meaningless, because a plan nobody checks is only an intention.
Controlling without planning is blind, because without a standard set in advance the
manager has nothing to control against.
Two arrows, not one. The lower one is the whole of Chapter 8's claim on
Chapter 4.
Two ways they differ, and one way they don't
Prescriptive vs evaluative
Planning is an intellectual exercise — thinking, articulating, analysing, to
prescribe a course of action. Controlling checks whether decisions were translated
into action, so it is evaluative.
Looking ahead vs looking back
Plans are made for the future, so planning looks ahead. Controlling is a
post-mortem of past activity, so it looks back — but only half of the statement
is true.
The one way they do not differ
Both are backward-looking and forward-looking. Planning is guided by past
experience; the corrective action taken by controlling aims to improve future
performance. Say this sentence and the 3-mark "comment" question is finished.
Why is "planning is looking ahead, controlling is looking back" only partly correct?
Because it is true of each function's starting point and false of its output.
Planning does look ahead — but it is not written in a vacuum. A firm plans next year's sales
from last year's figures, its past failures and its past cost overruns. In that sense
planning is also backward-looking.
Controlling does look back — a deviation report is a post-mortem of work already done. But
the last step of the process is corrective action, and corrective action can only affect
future performance. Nothing a manager does in July changes June's output. In that sense
controlling is also forward-looking.
Model closing line: "The statement is only partially correct, because planning
is guided by past experience and the corrective action initiated by controlling aims to improve
future performance. Both functions are therefore backward-looking as well as
forward-looking."
The confusable pair — planning vs controlling
Students routinely write…
"Controlling comes after planning and is therefore the last function of
management." · "Planning is done by top management, controlling is done by supervisors." ·
"Planning is looking ahead, controlling is looking back — full stop."
The first misses that controlling feeds straight back into planning. The second is
simply false: both are pervasive and are performed at every level. The third is half an
answer and scores like half an answer.
Four bases is the right length for a 3–4 mark "distinguish between" question.
Basis
Planning
Controlling
Meaning
Deciding in advance what is to be done, how, when and by whom — it
sets the standard.
Ensuring that activities are performed as per the plans — it
measures against the standard.
Nature
Prescriptive — an intellectual process of thinking and analysis that
prescribes a course of action.
Evaluative — it checks whether decisions have been translated into the
desired action.
Timing
The first function; it initiates the management process, before any
activity begins.
Performed during and after the activity; it completes one cycle of the
process.
Focus
Chiefly forward-looking, though guided by past experience.
Backward-looking in measurement, forward-looking in corrective action.
The case that can only go one way
Case 4 · Yamuna Freightways, Delhi
Arvind Bhalla runs 40 trucks on the Delhi–Jaipur and Delhi–Kanpur
routes. In April he set a standard of a 9-hour Delhi–Jaipur run and pressed his drivers
hard when they missed it. In September, after the expressway diversion, not one of 260 runs was
completed in 9 hours; the fastest was 10 hours 20 minutes. Arvind checked the
fuel logs and the driver rosters, found no fault with either, and reset the standard to 10
hours 30 minutes — then rebuilt the delivery promise he gives customers around the new
figure.
Question 6 4 marks
Arvind corrected the standard, not the performance. Was that controlling at
all? Identify the point of importance and the step of the process involved, and explain what
the case proves about the planning–controlling relationship.
Are you ready for the answer? 🤔
Answer
Yes — it is controllingHe measured, compared, analysed the cause,
and acted. Only the form of the action is unusual.
Judging accuracy of standardsThis is the point of importance
involved: a good control system verifies whether the standards themselves are accurate
and helps revise them as the environment changes.
Taking corrective action — step 5Where a deviation cannot be
corrected by managerial action, the standard itself may have to be revised. The
expressway diversion is an external factor outside his control.
What it provesThe output of controlling became the input of the
next plan — he rebuilt the customer delivery promise. Controlling improves
future planning, which is why the two are inseparable twins and controlling is not the
last function.
"Arvind checked the fuel logs and the driver rosters, found no fault with
either, and reset the standard to 10 hours 30 minutes — then rebuilt the delivery promise he
gives customers around the new figure."
★ Challenge — which twin failed?
★ Challenge 6 marks
Two firms miss the same target. Firm P set a detailed monthly production budget but
nobody compared actual output to it until the year ended. Firm Q weighed, counted and
reported output every single day, but had never written a target down. Both ended the year 22%
short. In each case, say which function failed and why, and state the general principle each
firm illustrates.
Are you ready for the answer? 🤔
Answer
Firm P — controlling failedA budget
existed, so planning was done. Nothing measured actual performance against it during the
year.
Firm P's principlePlanning without controlling is
meaningless — an unchecked plan is only an intention, and by December no corrective
action was possible.
Firm Q — planning failedMeasurement was excellent, but with no
standard there was nothing to compare the numbers with.
Firm Q's principleControlling is blind without
planning — with no predetermined standard, no deviation can be computed and step
3 of the process cannot even begin.
The common lessonNeither function is a complete management system
on its own; each supplies what the other lacks.
Which is worseFirm Q's failure is more fundamental. P at least
knows what it wanted; Q has a year of data that cannot be interpreted, so it cannot even
plan next year sensibly.
The controlling process — five steps and a loop
Five steps, two return arrows. Drop either arrow and controlling becomes a
one-off inspection.
Step 1 · Setting performance standards
Definition
Standards are the criteria against which actual performance is
measured. They serve as benchmarks towards which the organisation strives to
work.
Quantitative standards
Cost to be incurred, revenue to be earned, units to be produced and sold, time to be
spent. Prefer these — comparison in step 3 becomes mechanical.
Qualitative standards
Improving goodwill, raising the motivation level of employees. Where they are unavoidable,
define them so they can be measured — a fast-food chain measures "customer
satisfaction" as waiting time for a table, time to place the order, time to collect it.
One more property, often forgotten
Standards must be flexible. Because the internal and external environment changes, a
standard may have to be modified to stay realistic — which is where Case 4's Delhi expressway
came from.
Standards, by functional area
The textbook's own table — the HRM column carries only three. A 1-mark question is
regularly set straight off it: "Give any two standards a company could use to evaluate its
Finance and Accounting department."
Production
Marketing

Liquidity
Example · Chhattisgarh Fab Works, Bhilai
Rakesh's four standards, one from each column: 1,200 tonnes a month (production
quantity), rejects below 2% (production quality), absenteeism below 4% (HRM), and
a receivables cycle of 45 days (finance).
Step 2 · Measurement of actual performance
The rule
Performance must be measured in an objective and reliable manner, and — as far as
possible — in the same units in which the standard was set, so that step 3 is a
subtraction and not an argument.
The techniques
Personal observation, sample checking, performance reports, and
ratios such as gross profit ratio, net profit ratio and return on investment.
Measure during, not only after
Wherever possible, measure while the work is being done — every part checked before
assembly, gas particle levels monitored continuously in a plant.
Sample checking
In a small unit every piece can be checked. In a large one, certain pieces are checked
at random — that is sample checking, and it is a named technique.
Case 5 · Chamundi Soaps, Mysuru
Vasanthi's standard is moisture below 12%. She used to test the moisture of a finished
carton at the end of the shift. Since March she has tested one cake from every
tenth tray as it leaves the drying tunnel, and a bad tray is now pulled out four hours before
it would have reached the carton.
Question 7 3 marks
Name the technique of measurement Vasanthi is using, and state two reasons why the change
improved her control system.
Are you ready for the answer? 🤔
Answer
Sample checkingCertain units are checked at random rather
than every unit — the standard technique where checking everything is not feasible.
Measurement during performance, not after itMeasuring at the drying
tunnel rather than at the carton means the deviation is found while it can still be
corrected.
Same units as the standardMoisture percentage is measured in
exactly the units in which the standard was set, so comparison in step 3 needs no
interpretation.
"Since March she has tested one cake from every tenth tray as it leaves
the drying tunnel, and a bad tray is now pulled out four hours before it would have reached the
carton."
Step 3 · Comparison, and the word "deviation"
Definition
A deviation is the difference between actual performance and
the standard set. Comparison is easy where the standard is quantitative — a worker's weekly
output against the standard output for the week.
Example · the arithmetic is the whole of step 3
Standard: 300 tonnes a week. Actual: 268 tonnes. Deviation:
32 tonnes, or 10.7% adverse. Step 3 stops there. It does not ask why, and it does
not act — those are steps 4 and 5.
Where students lose the step
Answers routinely fuse steps 3, 4 and 5 into "he compared and took action". That is
one step's worth of marks for three steps' worth of content. Keep them separate:
compare → find the cause → act.
Question 8 1 mark
Which term is used to indicate the difference between standard performance and actual
performance?
Are you ready for the answer? 🤔
Answer
Deviation.
Step 4 · Analysing deviations — the filter
Definition
Critical point control — since it is neither economical nor
easy to keep a check on every activity, control should focus on the
key result areas (KRAs) that are critical to the organisation's success. These are set
as the critical points: if anything goes wrong there, the entire organisation
suffers.
A 15% rise in postal charges is noise. A 5% rise in labour cost is the
business.
Step 4 · Management by exception
Definition
Management by exception, often called control by exception,
rests on the belief that an attempt to control everything results in controlling
nothing. Therefore only significant deviations which go beyond the permissible limit
are brought to the notice of management.
Example · the textbook's own numbers
If the plan lays down a 2% increase in labour cost as the acceptable range of
deviation, only an increase beyond 2% goes to management. A 5% increase is a major
deviation and must receive immediate attention on a priority basis.
The four advantages — of critical point control and management by exception
Saves time and effortManagers deal only with significant
deviations.
Better utilisation of managerial talentAttention is focused on the
important areas of the business.
Facilitates delegationRoutine problems are left to
subordinates, which increases their morale — Chapter 5's delegation
doing Chapter 8's work.
Identifies critical problemsThe problems that need timely
action to keep the organisation on track are the ones that surface.
The pair inside step 4
Students routinely write…
"Critical point control and management by exception are the same thing." · "Management by
exception means the manager only manages the exceptional employees."
They are used together in step 4 and they are not the same. One chooses
which activities are watched. The other chooses how big a deviation in those
activities is worth reporting.
Both belong to step 4 — analysing deviations. Neither is a step in its own right.
Basis
Critical point control
Management by exception
Meaning
Control focuses on the key result areas critical to the organisation's
success.
Only deviations beyond the permissible limit are reported to management.
The question it answers
Which activities shall we watch at all?
How large must a deviation be before it reaches a manager?
Underlying belief
It is neither economical nor easy to check every activity.
An attempt to control everything results in controlling nothing.
In use
Fixes labour cost as a critical point; postal charges are not one.
Fixes 2% as the acceptable range; reports only the 5% rise.
The case the board keeps setting
Case 6 · Kongu Knitwear, Tiruppur
Lakshmi's cutting supervisor comes to her with a complaint. One operator, Bhanu, fell short
of his daily target by 10 pieces on each of two days against a daily standard of 480, and
the supervisor wants him dismissed. In the same fortnight the dyeing section
has run 6% over its permitted 2% chemical-cost variance, and the supervisor has not
mentioned it.
Question 9 4 marks
Name the principle of management control Lakshmi should apply, explain it, and say what she
should do about each of the two matters in the case.
Are you ready for the answer? 🤔
Answer
Management by exceptionAlso
called control by exception — an
attempt to control everything results in controlling nothing, so only deviations
beyond the permissible limit should reach management.
Bhanu's shortfall is not an exception10 pieces on 480 is a
2% deviation on two days. It is within any reasonable acceptable range and does not
warrant the top manager's attention, let alone dismissal.
The dyeing variance is the exception6% against a permitted 2% is a
major deviation in a key result area — cost — and demands
immediate attention on a priority basis.
What she should doSend Bhanu's case back to the supervisor as a
routine matter, and open the dyeing variance herself: analyse its cause, then take corrective
action.
"In the same fortnight the dyeing section has run 6% over its permitted 2%
chemical-cost variance, and the supervisor has not mentioned it."
Notice what the case is really testing: not whether you know MBE, but whether
you can see that the supervisor escalated the small deviation and buried the large
one.
Step 4 · Finding the cause
Identifying which deviations matter is only half of step 4. The other half is
finding why — because a corrective action aimed at the wrong cause is wasted.
The six recognised causes
Unrealistic standards · defective process · inadequacy of resources ·
structural drawbacks · organisational constraints · environmental factors
beyond the organisation's control.
Why the list matters in the paper
Application questions almost always plant the cause in the case. Naming it — "the deviation
arose from an unrealistic standard" — is what turns a 2-mark answer into a 4-mark
one.
Then, and only then
"The deviations and their causes are then reported, and corrective action taken
at the appropriate level." The reporting line matters: a shop-floor cause is corrected on
the shop floor, not in the boardroom.
Step 5 · Taking corrective action
Definition
No corrective action is required when deviations
are within acceptable limits. When
they go beyond the acceptable range, especially in important areas, they demand
immediate managerial attention so that the deviation does not recur and the standard is
accomplished.
The last row is the one students forget — and the one the best cases are built on.
Cause of the deviation
Corrective action
Workers lack the skill to meet the production target
Training of employees
An important project is running behind schedule
Assign additional workers and equipment; permit overtime
Defective machinery or process
Repair or replace the machine; redesign the process
The deviation cannot be corrected by managerial action at all
Revise the standard
Why step 5 makes controlling forward-looking
Every row of that table acts on the next batch, the next project, the
next quarter — never on the output already produced. That is why the last step, and not
the measurement, is what carries controlling's findings into Chapter 4's next plan.
Now write the case yourself
Now the other way round
Write a four-line case set in a Delhi logistics company that could only be
answered critical point control — not management by exception, and not
taking corrective action.
Three minutes. Then we read two out and try to break each one.

A model case, and the words that force the reading
Arvind Bhalla monitors eleven cost heads at Yamuna Freightways.
He decides that only two of them — fuel per kilometre and on-time delivery — will be reviewed
every week, because a slip in either would damage the firm's contracts, while the other nine are
reviewed once a year. No target has yet been crossed and no action has yet been taken.
The words that force the reading"only two of them… will be
reviewed", and the reason given: a slip in either would damage the firm's contracts.
That is the definition of a key result area.
The words that lock the others out"No target has yet been crossed"
excludes management by exception, which needs a deviation beyond a permissible limit. "No
action has yet been taken" excludes corrective action.
Why this is the transferable skillA good case does not merely
contain the right answer — it excludes the plausible wrong ones.
The whole process, as an answer
Question 10 5 marks
Explain the steps involved in the process of controlling.
Are you ready for the answer? 🤔
Answer
A 5-mark question wants 5 points — and this question has exactly five
steps, which is why it is the safest long answer in the unit.
Setting performance standardsStandards are the criteria against
which actual performance is measured; they may be quantitative or qualitative, and must be
flexible.
Measurement of actual performanceMeasured objectively and, as far
as possible, in the same units as the standard — by personal observation, sample
checking or performance reports.
Comparing actual performance with standardsThe comparison reveals
the deviation between actual and desired results.
Analysing deviationsFix an acceptable range, apply
critical point control
and management by exception,
and identify the exact cause of each significant deviation.
Taking corrective actionNone is needed within acceptable limits;
beyond them, act to remove the cause — or revise the standard if the deviation cannot
be corrected by managerial action.
★ Challenge — which step failed?
Case 7 · Chhattisgarh Fab Works, Bhilai
Rakesh's quality clerk records the reject rate of every batch, faithfully, in a register. The
register showed rejects at 4.6% against a standard of 2% for eleven straight weeks.
The clerk wrote "above standard" against each week and filed the register; no
one asked why, and the worn electrode grade that caused it was found only when a customer
returned a consignment.
★ Challenge 6 marks
Which steps of the controlling process were performed, which were not, and what did the
failure cost? Then answer the harder question: does this firm have a control system at
all?
Are you ready for the answer? 🤔
Answer
Step 1 was performedA standard of 2% rejects existed and was
written down.
Step 2 was performed, wellEvery batch was measured, in the units of
the standard.
Step 3 was performed"Above standard" against each week is the
comparison; the deviation was identified.
Step 4 failedNobody analysed the deviation. The cause — the worn
electrode grade — was never identified, so no corrective action could be aimed at
anything.
Step 5 therefore never happenedEleven weeks of 2.6-point adverse
deviation went uncorrected until a customer returned the goods — a loss of orders on top of
the material loss.
Does the firm have a control system?No. It has a
measurement system. Controlling is a process, and a process that stops at step 3
produces information nobody uses — the failure mode that "controlling is only checking"
always produces.
"The clerk wrote 'above standard' against each week and filed the
register; no one asked why, and the worn electrode grade that caused it was found only when a
customer returned a consignment."
What the syllabus does not ask for
Verified against the CBSE curriculum document for 2026-27
Unit 8 lists exactly three things: controlling — concept and importance, the
relationship between planning and controlling, and the steps in the process of
control. That is all.
What older question banks still carry
The NCERT chapter's own summary and key-terms list still mention techniques of
managerial control — break-even analysis, budgetary control, ratio analysis, responsibility
accounting, return on investment, management audit, PERT and CPM, and Management Information
Systems. Guides printed before the rationalisation still set "Explain the techniques of
managerial control" as a long-answer question.
These are not in the current syllabus and will not be asked. Know the names so a stray
question in a sample paper does not frighten you; do not spend revision time on them.
What is examinable, and often
Two names inside step 4 — critical point control
and management by exception —
are examinable, because they are part of the process, not techniques of it. That
distinction is the whole reason this slide exists.
Back to Chapter 4 — the loop, stated in words
Chapter 8 → Chapter 4
Chapter 4 said planning is the primary function because it precedes all the others,
and that a plan is built on premises — assumptions about what the future will be like.
Chapter 8 has just shown where the honest premises come from: the deviations of the last
cycle, and the causes the control system identified for them.
The one sentence that ties Part A together
Planning sets the standard; controlling reports the deviation; the deviation becomes the
premise of the next plan. A firm that runs this loop learns. A firm that stops at step 3
only accumulates paper.
Example · one turn of the loop at Yamuna Freightways
April: plan says 9 hours Delhi–Jaipur. September: control reports 260 runs, none
inside 9 hours, cause external. October: the new plan says 10 hours 30 minutes, and the
customer delivery promise is rewritten around it. Chapter 4 and Chapter 8 are the same
conversation, six months apart.
Part A closes — the management cycle
Five functions, one ring. The amber arrow is the whole of Chapter 8's argument in
one stroke.

Question 12 3 marks
"An effort to control everything may end up in controlling nothing." Explain.
Are you ready for the answer? 🤔
Answer
The statement refers to management by exceptionAlso
called control by exception — a principle of management control applied
while analysing deviations, which is step 4 of the process.
Only significant deviations are reportedAn acceptable range of
deviation is fixed in advance; only deviations that go beyond the permissible limit are
brought to the notice of management.
Why the alternative failsA manager who investigates every small
variance has no time left for the deviations that matter — so managerial attention is spread
thin, routine problems are not delegated, and the critical problem is missed.

Question 13 4 marks
"Planning is looking ahead and controlling is looking back." Comment.
Are you ready for the answer? 🤔
Answer
The statement is only partially correctSay this in the first line.
An answer that simply agrees cannot score above half.
Where it is truePlans are prepared for the future and are based on
forecasts, so planning is a forward-looking function; controlling is a
post-mortem of past activities to find deviations, so it is
backward-looking.
Where it is false — planningPlanning is guided by past
experience: last year's results and last year's deviations are the premises of this year's
plan.
Where it is false — controllingThe corrective
action initiated by controlling aims to improve future performance. Both
functions are therefore backward-looking as well as forward-looking.
Exam practice · the relationship, in full
Question 14 4 marks
Discuss the relationship between planning
and controlling.
Are you ready for the answer? 🤔
Answer
They are the inseparable twins of managementA system of control
presupposes the existence of standards, and those standards of performance are
provided by planning. Planning initiates the process; controlling completes it.
Planning without controlling is meaninglessOnce a plan becomes
operational, control is needed to monitor progress, measure it, discover deviations and
initiate corrective measures. An unchecked plan is only an intention.
Controlling is blind without planningIf standards are not set in
advance, managers have nothing to control. Where there is no plan there is no basis of
controlling, and no deviation can even be computed.
They reinforce each other, in both directionsPlanning based on
facts makes controlling easier and more effective; and controlling
improves future planning by supplying information derived from past experience.
Point 4 is the one that separates a full-mark answer from a half one. Most
students stop at "planning comes first" — which describes a queue, when the examiner is
looking for a loop.

Question 15 6 marks
Explain the importance of controlling in an organisation. What problems are faced by an
organisation in implementing an effective control system?
Are you ready for the answer? 🤔
Answer — two halves, and the examiner marks them separately
Split the page: any four importances, then all four limitations.
A single undivided list of eight points loses the structure marks.
Importance — judging accuracy of standardsVerifies whether the
standards set were accurate and objective, and helps revise them.
Importance — efficient use of resources / employee motivationReduces
wastage and spoilage; employees know in advance what is expected of them.
Importance — order, discipline and coordinationMinimises dishonest
behaviour; mutually consistent standards pull departments one way.
Problems — quantitative standards and external factorsStandards
cannot always be set in numbers (morale, job satisfaction), and the firm cannot control
government policy, technology or competition.
Problems — resistance and costEmployees see control as a
restriction on freedom; and the cost of the control system must not
exceed the benefit derived from it.
Exam practice · case study 1
Case 8 · Chamundi Soaps, Mysuru
Vasanthi Rao planned 60,000 cakes and a wastage limit of 3%
for the festive quarter. At the end of the quarter, output was 51,000 cakes and wastage 7.4%.
She examined the daily logs, found that the two new packing operators hired in September had
never been shown the tray-loading method, and put them through a week's structured programme
before the next quarter began. She also noticed that the sandalwood oil supplier
had raised his price twice in the quarter following a change in forest-produce levy, which she
could do nothing about, so she rewrote the cost standard for the coming quarter around the new
price.
Question 16 6 marks
(a) Identify the steps of the controlling process visible in the case, in order.
(b) Identify the two causes of deviation and the corrective action taken for each.
(c) Which limitation of controlling does the second cause illustrate?
Are you ready for the answer? 🤔
Answer
Step 1 — setting performance standards60,000 cakes and 3% wastage,
both quantitative, set before the quarter began.
Steps 2 and 3 — measurement and comparisonOutput 51,000 against
60,000 and wastage 7.4% against 3%: a deviation of 9,000 cakes and 4.4 percentage
points.
Step 4 — analysing deviationsShe examined the daily logs and
identified two causes: untrained operators, and a supplier price rise.
Cause 1 — inadequacy of resources / untrained staffCorrective
action: training of the two new
operators before the next quarter — a classic step 5.
Cause 2 — environmental factors beyond the firm's controlCorrective
action: none is possible, so she revised the standard — the permitted
response when a deviation cannot be corrected by managerial action.
The limitationLittle control over external factors — a
change in a government levy is part of the firm's environment, not of its operations.
"She also noticed that the sandalwood oil supplier had raised his price
twice in the quarter following a change in forest-produce levy, which she could do nothing
about, so she rewrote the cost standard for the coming quarter around the new price."

Case 9 · Yamuna Freightways, Delhi
Yamuna Freightways has lost three contracts in a year. Its rates are competitive and its
trucks are new, but customers complain of missed delivery windows. The firm has a detailed
annual business plan with route-wise targets. Nobody in the firm has ever
compared a month's actual running times with that plan; last year's copy was found unopened in
a drawer in February. Arvind now wants to rebuild the system.
Question 17 6 marks
(a) Which function of management has failed, and which has not?
(b) State the benefits the firm will derive from a good control system.
(c) Set out the steps Arvind should follow to remove the problem.
Are you ready for the answer? 🤔
Answer
Planning has not failed; controlling hasA detailed plan with
route-wise targets exists — step 1 is done. Nothing was ever measured against it.
The governing principlePlanning without
controlling is meaningless — a plan nobody checks is only an intention, and the firm
discovered its failure through lost contracts rather than through its own reports.
Benefit — accomplishing organisational goalsControl would have
revealed the missed delivery windows month by month, in time to act.
Benefit — efficient use of resources and coordinationRoute-wise
comparison would show where trucks and driver hours are being wasted, and align the
dispatch, loading and delivery sections to the same targets.
Benefit — improving employee motivation and judging standardsDrivers
would know their targets in advance; and the firm would learn whether the route-wise
targets were realistic at all.
The steps to followSet route-wise time and on-time-delivery
standards; measure actual running times monthly from the GPS logs; compare and compute the
deviation; analyse it using critical point control
(on-time delivery is the key result
area) and management by exception
(act only beyond the permitted variance); then take
corrective action — or revise the standard where the cause is external.
"Nobody in the firm has ever compared a month's actual running times with
that plan; last year's copy was found unopened in a drawer in February."
One last drill, the other way round
Now the other way round
Write a four-line case set in a Bhilai steel fabrication unit that could only be
answered "controlling is blind without planning" — not "planning without controlling
is meaningless".
The two are mirror images, so the words you leave out matter more than the ones
you put in.
Are you ready for a model answer? 🤔
A model case, and the words that force the reading
Sunita Netam weighs every consignment leaving her Bhilai fabrication
shop and files a daily despatch report. No monthly tonnage target has ever been fixed for the
shop. At the year-end review her reports fill four files, but when the bank asks whether the
shop met its capacity, nobody can say — there is nothing the figures can be compared
with.
The words that force the reading"No monthly tonnage target has ever
been fixed" and "nothing the figures can be compared with". Measurement is present; the
standard is absent — so step 3 cannot begin and the control system is
blind.
The words that lock the mirror image outTo make it "planning
without controlling is meaningless" you would have to reverse them: a target exists, and
nobody measures. If your case has both a target and no measurement, you have written the
other question's answer.
End of Chapter 8 · End of Part A
Next: where the money comes from
Part A is complete — the management cycle closes here. Part B asks the two
questions that keep the firm alive: where the money comes from, and how the firm reaches
the person who will buy from it.
Chapter 9 will need one idea from this chapter by
name: the standard. A financial plan is a set of standards expressed in rupees — and the
three financial decisions are simply Chapter 4's planning and Chapter 8's controlling, applied to
money.
