3  Functions of Management — Planning, Organising, Staffing, Directing, Controlling

3.1 The Five Functions

If the previous topic answered what management is, this one answers what managers do. Henri Fayol’s original five — plan, organise, command, coordinate, control (1916) — were re-grouped into the modern textbook sequence used by Koontz & Weihrich and Robbins & Coulter: Planning, Organising, Staffing, Directing (Leading), Controlling. Coordination is no longer counted as a separate function — it is treated as the essence that runs through all the others. Luther Gulick and Lyndall Urwick’s expanded mnemonic POSDCORB (1937) — Planning, Organising, Staffing, Directing, Co-ordinating, Reporting, Budgeting — is still examined.

TipFunction listings — three to memorise

NotePYQ cue — Fayol vs Koontz

Command” appears only in Fayol’s original list. The modern textbook substitutes “Directing” or “Leading”. If the stem cites commanding, expect Fayol; if it cites leading, expect Koontz or Robbins.

3.2 Planning

Planning is deciding in advance what to do, how to do it, when to do it and who is to do it (Koontz & Weihrich). It is the primary function — every other function works on what planning has set down. Planning bridges the gap between where the organisation is and where it wants to be.

3.2.1 Nature of Planning

TipSix features of planning
  • Goal-oriented — every plan exists to achieve a stated objective.
  • Forward-looking — concerned with the future, never the past.
  • Pervasive — applied at all levels and in every department.
  • Intellectual — requires thinking, judgement and foresight.
  • Continuous — once a plan ends, the next one begins.
  • Integrated — strategic, tactical and operational plans must align vertically.

3.2.2 Steps in Planning — Koontz & Weihrich (8 steps)

TipEight Steps in the Planning Process
# Step What happens
1 Being aware of opportunities Scanning the environment — external (PESTEL) and internal (SWOT)
2 Establishing objectives Setting targets — what, where, by when, how much
3 Developing premises Forecast assumptions about the planning environment
4 Identifying alternatives Listing possible courses of action
5 Comparing alternatives Evaluating against objectives and premises
6 Choosing an alternative The point of decision
7 Formulating derivative plans Sub-plans to support the master plan
8 Numberising plans by budgeting Converting plans into measurable resource allocations
NotePlanning Premises

Premises are the forecast assumptions against which plans are made. They are classified by:

  • Origin — internal vs external.
  • Nature — tangible vs intangible.
  • Controllability — controllable (advertising spend), semi-controllable (employee productivity), uncontrollable (inflation, war).
  • A common PYQ stem: “Forecast assumptions about the environment in which a plan is to be implemented are called _____ .” → Planning premises.

3.2.3 Types of Plans — The Hierarchy

TipA Hierarchy of Plans (Koontz)
Plan type Time horizon Used for Example
Mission / Purpose Indefinite Why the organisation exists “To organise the world’s information” (Google)
Objectives / Goals Long to short Targets Achieve 15 % ROI
Strategies Long-term (3–5 years +) Direction in face of competition Cost-leadership, differentiation
Policies Continuing Boundaries for repeated decisions “Promotion is from within”
Procedures Continuing Required sequence of steps Steps to process a refund
Rules Continuing Specific dos and don’ts “No smoking on shop floor”
Programmes Project-bound Coordinated bundle of activities New-product launch programme
Budgets Typically one year Plans expressed in numbers Annual revenue and capex budget
NoteStanding plans vs Single-use plans
  • Standing plans are used repeatedly: policies, procedures, rules. They guide recurring decisions.
  • Single-use plans are made for one specific situation: programmes, projects, budgets. They retire after the situation passes.

By scope and level:

TipStrategic vs Tactical vs Operational
Plan level Made by Time Concern
Strategic Top management 3–5 years + Direction, competitive position
Tactical Middle management 1–3 years Translation of strategy into department targets
Operational Lower management Days–months Day-to-day execution

3.2.4 MBO — Management by Objectives

Peter Drucker introduced Management by Objectives in The Practice of Management (1954) and George Odiorne extended it in Management by Objectives (1965). MBO is a planning + performance system in which superior and subordinate jointly set specific, measurable objectives, periodically review progress, and reward on the basis of objective achievement.

TipMBO process
Step Activity
1 Set organisational objectives (top)
2 Cascade them down — department and individual
3 Joint goal-setting between superior and subordinate
4 Implement with autonomy
5 Periodic progress review
6 Appraisal and reward
7 Recycle — feed lessons into the next round

SMARTSpecific, Measurable, Achievable, Relevant, Time-bound — is the modern test of a usable objective (George Doran, Management Review, 1981).

NoteDrucker’s eight key result areas

Drucker listed eight areas where objectives must be set: market standing · innovation · productivity · physical and financial resources · profitability · manager performance and development · worker performance and attitude · public responsibility.

3.3 Organising

Organising arranges resources and activities into a structure that lets the plan be executed. Koontz defines it as “the process of identifying and grouping the work, defining and delegating responsibility and authority, and establishing relationships for the purpose of enabling people to work together effectively”.

3.3.1 Steps in Organising

TipFive steps in organising
  1. Identify activities required to reach the objectives.
  2. Group activities into manageable units (departments).
  3. Assign authority and responsibility to each position.
  4. Establish reporting relationships and communication channels.
  5. Provide for coordination across departments.

3.3.2 Building Blocks of Organising

TipKey concepts in organising
Concept Meaning Why it matters
Authority Right to act and command Flows down the scalar chain
Responsibility Obligation to perform Flows up; cannot be delegated
Accountability Liability for results Flows up; cannot be passed on
Power Ability to influence (formal + informal) Wider than authority — see French & Raven’s five bases
Delegation Transfer of authority for specific tasks Frees the manager, develops the subordinate
Span of management / control Number of subordinates one manager can supervise Narrow span → tall structure; wide span → flat structure
Centralisation / Decentralisation Where decisions are taken Trades control vs responsiveness
Departmentation Basis for grouping activities Function, product, region, customer, process, matrix
NoteTagline

The principle “authority can be delegated, responsibility cannot” recurs in NTA stems. It is often paraphrased: “a manager is accountable to the superior for whatever the subordinate does”.

3.3.3 Span of Control — Graicunas’s Formula

V.A. Graicunas (1933) proposed a mathematical formula for the relationships a manager must monitor as the span grows. If a manager has n subordinates, the total relationships are:

\[R = n \left( \frac{2^n}{2} + n - 1 \right)\]

TipGraicunas table — relationships grow combinatorially
n (subordinates) Relationships R
2 6
3 18
4 44
5 100
6 222
7 490

The lesson: span of control should be kept narrow because the relationships a manager must monitor explode with each additional subordinate. Modern textbook ranges: narrow span 4–8 subordinates; wide span 10–20+ in flat, knowledge-work organisations.

3.3.4 Authority Relationships — Line, Staff, Functional

TipThree types of authority
Type Meaning Example
Line Direct authority to command and direct activities along the chain Production manager over shift supervisor
Staff Advisory authority — assists line HR adviser, legal counsel
Functional Limited authority granted to a specialist in a defined area HR head’s authority over leave policies firm-wide

Line and staff conflict is a perennial topic — staff complain that line ignores their advice; line complains that staff usurp authority and lack accountability.

3.3.5 Departmentation — Six Bases

TipBases of departmentation
Basis Example
Functional Production, marketing, HR, finance
Product / Division Lighting, healthcare, transportation (GE-style)
Geographic / Territory North, South, East, West zones
Customer Retail, corporate, government clients
Process / Equipment Forging, machining, painting, assembly
Matrix Functional × Product (two-boss system)

The detailed treatment of organisation structure — Mintzberg’s five parts, mechanistic vs organic, contingency factors — appears in Topic 5 of this chapter.

3.4 Staffing

Staffing fills and keeps filled the positions in the organisation structure. Koontz lists eight elements — manpower planning, recruitment, selection, placement, training and development, performance appraisal, compensation, and separation.

TipThe Staffing Cycle
Stage Activity Output
Manpower planning Forecast people needs Number and kind of people required
Recruitment Attract a pool of candidates Application list
Selection Choose from the pool Offer letter
Placement & induction Put on the job, orient Employee at workstation
Training & development Improve skills and knowledge Capable employee
Performance appraisal Measure on the job Feedback, ratings
Compensation Reward for performance Pay, benefits
Separation Retirement, resignation, dismissal Position to be re-filled
NoteIndependent function or sub-function?

Staffing is treated as an independent function in modern texts (Koontz, Robbins, Stoner). Older Indian texts and Fayol’s listing fold it into organising or directing. The HR-specific aspects are taken up in detail in Chapters 2 and 3 of this book.

3.5 Directing (Leading)

Directing is the executory function — it sets people in motion. Its four sub-functions are supervision, motivation, leadership and communication.

TipFour pillars of directing
Pillar What it does Theory anchor
Supervision Overseeing the work of subordinates Span of control; Likert’s four systems
Motivation Inspiring willingness to work Maslow, Herzberg, McClelland, Vroom, Adams
Leadership Influencing people toward goals Trait, behavioural, contingency, transformational
Communication Exchanging meaning Shannon-Weaver, Berlo SMCR (Topic 3)

3.5.1 Motivation theories — quick anchors

TipMotivation theories — at a glance
Theory Author Year Core idea
Hierarchy of needs Abraham Maslow 1943 Five levels — physiological → safety → social → esteem → self-actualisation
Two-factor theory Frederick Herzberg 1959 Hygiene factors prevent dissatisfaction; motivators produce satisfaction
Theory X / Theory Y Douglas McGregor 1960 Two opposing assumptions about workers
ERG theory Clayton Alderfer 1969 Existence, Relatedness, Growth — collapses Maslow
Three needs theory David McClelland 1961 Need for Achievement, Affiliation, Power
Expectancy theory Victor Vroom 1964 Motivation = Expectancy × Instrumentality × Valence
Equity theory J. Stacy Adams 1963 People compare input/output ratios with referents
Goal-setting theory Locke & Latham 1968 onward Specific, difficult goals lift performance

3.5.2 Leadership styles — quick anchors

TipLeadership styles — at a glance
Style / model Author Key idea
Autocratic / Democratic / Laissez-faire Kurt Lewin (1939) Three styles based on decision authority
Managerial Grid Blake & Mouton (1964) Concern for People (1–9) × Concern for Production (1–9); 9,9 is “team management”
Contingency model Fred Fiedler (1967) Leader–member relations + task structure + position power determine fit
Path-Goal Robert House (1971) Leader clears the path to subordinate goals
Situational Hersey & Blanchard (1969) Style varies with follower readiness — telling, selling, participating, delegating
Transactional vs Transformational Bass (1985), Burns (1978) Exchange-based vs vision-and-charisma-based

Detailed treatment of motivation and leadership belongs to the OB chapter (Topics 15–18).

3.6 Controlling

Controlling is the function that closes the loop: it measures actual performance against planned standards, identifies deviations, and triggers corrective action. Koontz defines it as “the measurement and correction of performance to make sure that enterprise objectives and the plans devised to attain them are accomplished”.

3.6.1 The Control Process

flowchart LR
  S[1. Establish<br/>standards] --> M[2. Measure<br/>actual performance]
  M --> C[3. Compare with<br/>standards]
  C --> A{4. Deviation?}
  A -- Yes --> CR[5. Take<br/>corrective action]
  A -- No --> OK[Continue]
  CR -. feedback .-> S
    classDef default fill:#003366,color:#ffffff,stroke:#ffcc00,stroke-width:3px,rx:10px,ry:10px;

The four standard steps are Standards → Measurement → Comparison → Corrective action. The feedback loop makes management a closed-loop activity — the output of control feeds the next round of planning.

3.6.2 Types of Control

TipThree control types by timing
Type Timing Example
Feedforward (preventive) Before the activity Inspecting raw material before production
Concurrent (real-time) During the activity Supervisor on the shop floor; SCADA dashboard
Feedback (post-action) After the activity Variance analysis at month-end

By focus — strategic / tactical / operational (mirroring planning levels); by what is being controlled — financial, quality, inventory, behavioural.

3.6.3 Techniques of Control

TipCommon control techniques
Technique What it controls Where it lives
Budgetary control Costs, revenues, capex Finance
Standard costing & variance analysis Cost performance Finance / production
Statistical Quality Control (SQC) Process quality Production
Break-even analysis Sales–cost–profit relationship Finance / marketing
Ratio analysis Financial performance Finance
Internal audit Compliance and process integrity Audit
Management Information System (MIS) Information for decisions IT / management
Balanced Scorecard (Kaplan & Norton, 1992) Multi-dimensional performance Strategy
PERT / CPM Project schedules Operations
Six Sigma — DMAIC Process variation Quality
NoteManagement by Exception (MBE)

A control discipline credited to F.W. Taylor and codified by Lester R. Bittel (1964): managers should focus only on significant deviations from standard and let routine variances be handled by subordinates. The principle prevents managerial overload.

Robert N. Anthony’s distinction between strategic planning, management control and operational control (1965) is a useful frame at the postgraduate level.

3.7 Coordination — the Essence

Mary Parker Follett described coordination as “the orderly arrangement of group effort to provide unity of action in the pursuit of a common purpose” (Dynamic Administration, 1941). Coordination is not a sixth function — it is the thread that runs through all five.

TipFollett’s four principles of coordination
Principle Meaning
Direct contact People at all levels meet face-to-face, not only through paper
Early stage Coordination must begin during planning, not after execution
Reciprocal relationship Every part affects and is affected by every other part
Continuity Coordination is a continuous, never-ending process
NoteCoordination vs Cooperation
  • Coordination is a managerial function — it is deliberate, orderly, and aimed at unity of action. It can be enforced.
  • Cooperation is voluntary — willing collaboration among individuals. It cannot be enforced.
  • Coordination is broader; cooperation is one of its inputs.

3.8 Practice Questions

Q 01 Five Functions Easy

Which of the following is not a managerial function in the Koontz–Weihrich classification?

  • APlanning
  • BOrganising
  • CMarketing
  • DControlling
View solution
Correct Option: C
Koontz–Weihrich's five functions are Planning, Organising, Staffing, Directing/Leading, Controlling. Marketing is a business function, not a management function.
Q 02 POSDCORB Medium

The "B" in POSDCORB stands for:

  • ABranding
  • BBudgeting
  • CBargaining
  • DBriefing
View solution
Correct Option: B
POSDCORB = Planning, Organising, Staffing, Directing, CO-ordinating, Reporting, Budgeting (Gulick & Urwick, 1937).
Q 03 Function Matching Medium

Match the function with its description:

(i) Planning (a) Filling positions in the organisation
(ii) Organising (b) Measuring and correcting performance
(iii) Staffing (c) Deciding in advance what to do
(iv) Controlling (d) Grouping activities and assigning authority
  • A(i)-(c), (ii)-(d), (iii)-(a), (iv)-(b)
  • B(i)-(a), (ii)-(b), (iii)-(c), (iv)-(d)
  • C(i)-(d), (ii)-(c), (iii)-(b), (iv)-(a)
  • D(i)-(b), (ii)-(a), (iii)-(d), (iv)-(c)
View solution
Correct Option: A
Planning → deciding in advance; Organising → grouping activities; Staffing → filling positions; Controlling → measuring and correcting.
Q 04 Primary function Easy

Which is rightly called the "primary function" of management — the one on which the others depend?

  • AOrganising
  • BPlanning
  • CControlling
  • DStaffing
View solution
Correct Option: B
Planning sets the objectives and the course; every subsequent function works on what planning has set down.
Q 05 Planning Premises Medium

Forecast assumptions about the environment in which a plan is to be implemented are called:

  • AObjectives
  • BStandards
  • CPlanning premises
  • DStrategies
View solution
Correct Option: C
Planning premises are the assumptions under which plans operate — economic, political, technological, social. Koontz lists them as Step 3 of the planning process.
Q 06 Types of Plans Medium

"Promotion is from within" is best classified as a:

  • ARule
  • BPolicy
  • CProcedure
  • DProgramme
View solution
Correct Option: B
A policy is a continuing guide to repeated decisions — it leaves room for managerial discretion. A rule is rigid (no discretion); a procedure is a sequence of steps.
Q 07 Standing vs Single-use Medium

Which of the following is a "single-use" plan?

  • APolicy
  • BProcedure
  • CRule
  • DProgramme
View solution
Correct Option: D
Single-use plans (programmes, projects, budgets) retire after the situation passes. Standing plans (policies, procedures, rules) guide recurring decisions.
Q 08 MBO Easy

Management by Objectives (MBO) was popularised by:

  • AF.W. Taylor
  • BHenri Fayol
  • CPeter Drucker
  • DHenry Mintzberg
View solution
Correct Option: C
Peter Drucker introduced MBO in The Practice of Management (1954). The standard test of objectives is SMART.
Q 09 SMART Easy

In the SMART criterion for objectives, "A" stands for:

  • AAggressive
  • BAchievable
  • CAudited
  • DAccountable
View solution
Correct Option: B
SMART = Specific, Measurable, Achievable, Relevant, Time-bound (George Doran, 1981).
Q 10 Delegation Easy

"Authority can be delegated, but ____ cannot." Fill in the blank.

  • APower
  • BResponsibility
  • CWorkload
  • DDecision-making
View solution
Correct Option: B
A bedrock principle of organising: responsibility cannot be delegated. A manager remains accountable to the superior for whatever the subordinate does.
Q 11 Span of Control Easy

A "wide span of management" tends to produce a structure that is:

  • ATall
  • BFlat
  • CMatrix
  • DCentralised
View solution
Correct Option: B
Wide span → fewer levels → flat. Narrow span → more levels → tall.
Q 12 Graicunas Hard

V.A. Graicunas's formula for the relationships a manager must monitor predicts that with 5 subordinates there are:

  • A25 relationships
  • B50 relationships
  • C100 relationships
  • D222 relationships
View solution
Correct Option: C
Graicunas (1933): R = n(2^n/2 + n − 1). For n=5: 5(16 + 4) = 100. For n=6 it jumps to 222 — the lesson is to keep span narrow.
Q 13 Authority Types Medium

A legal counsel who advises but does not command line departments exercises which type of authority?

  • ALine authority
  • BStaff authority
  • CFunctional authority
  • DCharismatic authority
View solution
Correct Option: B
Staff authority is advisory. Line authority commands the chain; functional authority is a limited grant of command in a specialist area.
Q 14 Coordination Easy

Coordination is best described as:

  • AThe sixth function of management
  • BA separate department in the organisation
  • CThe essence of management running through all functions
  • DSynonymous with cooperation
View solution
Correct Option: C
Coordination is the essence, not a separate function. Mary Parker Follett described it as the orderly arrangement of group effort for unity of action.
Q 15 Coordination vs Cooperation Medium

Which of the following statements is correct?

  • ACooperation is enforceable; coordination is voluntary
  • BCoordination is enforceable; cooperation is voluntary
  • CBoth are voluntary
  • DBoth are enforceable
View solution
Correct Option: B
Coordination is a *managerial function* — it can be enforced. Cooperation is *voluntary* willingness to work together and cannot be enforced.
Q 16 Control Timing Easy

A control system that operates before the activity begins is called:

  • AFeedback control
  • BConcurrent control
  • CFeedforward control
  • DPost-action control
View solution
Correct Option: C
Feedforward = before; concurrent = during; feedback = after. Inspecting raw material before production is a feedforward control.
Q 17 Control Process Medium

Which of the following is not a step in the standard control process?

  • AEstablishing standards
  • BMeasuring performance
  • CForecasting the future
  • DTaking corrective action
View solution
Correct Option: C
Standard control steps are Standards → Measure → Compare → Corrective action. Forecasting belongs to planning.
Q 18 MBE Medium

"Management by Exception" requires that managers focus only on:

  • ARoutine variances
  • BSignificant deviations from standard
  • CFuture opportunities only
  • DPast performance only
View solution
Correct Option: B
Management by Exception (Taylor; codified by Bittel 1964) directs managerial attention to significant deviations; routine ones are handled by subordinates.
Q 19 Balanced Scorecard Medium

The Balanced Scorecard (1992) was developed by:

  • ADrucker and Odiorne
  • BKaplan and Norton
  • CPorter and Lawler
  • DHamel and Prahalad
View solution
Correct Option: B
Robert Kaplan and David Norton introduced the Balanced Scorecard in their 1992 HBR article — four perspectives: financial, customer, internal process, learning & growth.
Q 20 Follett Hard

Mary Parker Follett's principle that *coordination must begin during planning, not after execution* is called the principle of:

  • ADirect contact
  • BEarly stage
  • CReciprocal relationship
  • DContinuity
View solution
Correct Option: B
Follett's four principles: Direct contact, Early stage, Reciprocal relationship, Continuity (*Dynamic Administration*, 1941).

3.9 Quick Recall

ImportantQuick recall
  • Five functions (Koontz, Robbins): Planning · Organising · Staffing · Directing · Controlling. POSDCORB adds CO-ordinating · Reporting · Budgeting (Gulick & Urwick 1937).
  • Fayol’s original five (1916): Plan, Organise, Command, Coordinate, Control — note “command” not “lead”.
  • Planning steps (Koontz, 8): opportunity → objectives → premises → alternatives → comparison → choice → derivative plans → budgeting.
  • Plan hierarchy: Mission → Objectives → Strategies → Policies → Procedures → Rules → Programmes → Budgets. Standing (policy/procedure/rule) vs Single-use (programme/project/budget).
  • MBO (Drucker 1954; Odiorne 1965) — joint goal-setting; SMART = Specific, Measurable, Achievable, Relevant, Time-bound (Doran 1981).
  • Organising tagline: authority delegated, responsibility never. Authority flows down, responsibility flows up.
  • Graicunas (1933): R = n(2ⁿ/2 + n − 1). n=4 → 44, n=5 → 100, n=6 → 222.
  • Authority types: Line (command), Staff (advisory), Functional (limited specialist command).
  • Departmentation bases: Functional, Product, Geographic, Customer, Process, Matrix.
  • Directing’s 4 pillars: Supervision · Motivation · Leadership · Communication.
  • Control process (4 steps): Standards → Measure → Compare → Corrective action. Three timings: Feedforward / Concurrent / Feedback.
  • Control techniques: Budgetary, Standard costing, SQC, BEP, Ratio, Audit, MIS, Balanced Scorecard (Kaplan & Norton 1992), PERT/CPM, Six Sigma.
  • MBE (Taylor; Bittel 1964) — focus only on significant deviations.
  • Coordination ≠ sixth function → it is the essence. Follett’s 4 principles: Direct contact · Early stage · Reciprocal relationship · Continuity. Coordination is enforceable; cooperation is voluntary.
