Principles of Management Class 12 Notes: Taylor’s Science and Fayol’s 14 Principles

These are the revision notes for Principles of Management, Chapter 2 of the Class 12 Business Studies textbook. The page compresses the whole chapter into what you actually need: the meaning, nature and significance of management principles, Taylor’s scientific management, Fayol’s 14 principles, the Fayol–Taylor comparison, and how to structure answers to the chapter’s own exercise types.

Everything here follows the 2026-27 session and NCERT’s rationalised Class 12 Business Studies textbook (Part I).

The chapter builds in three blocks — concept first, then Taylor’s shop-floor approach, then Fayol’s organisation-wide approach. Work through the page in that order. Every explanation block follows the same teaching pattern: Name → Define → Example → Link, which is also the pattern of a complete written answer.

The tables carry most of the definitions, so they double as a fast revision grid before a class test.

Chapter Roadmap: Three Blocks of Management Theory

The chapter opens with Toyota’s guiding principles (NCERT, p. 30) to show what a principle-driven company looks like, then sets three learning objectives: state the meaning, nature and significance of principles of management; explain Taylor’s principles and techniques of scientific management; and explain Fayol’s principles (p. 30). Everything in the chapter belongs to one of the blocks below.

Keep this map in mind: “explain the nature/significance” asks come from Block 1, “scientific management” from Block 2, “Fayol’s principles” from Block 3, and “distinguish Taylor and Fayol” from the comparison. All the Class 12 Business Studies notes follow the same book, and you can reach every other subject from the Class 12 notes hub or the wider CBSE notes library.

Key Terms and Definitions: Principles, Techniques and Values

Three terms from page 33 are constantly confused, so fix them first: principles are guidelines for decisions and behaviour, techniques are step-by-step procedures used to reach goals, and values are socially desirable rules with moral overtones that society forms through common practice.

You practise a principle through techniques, and you cannot ignore values while practising principles, because businesses carry social and ethical responsibilities (NCERT, p. 33).

One more distinction from pages 32–33: management principles are not as rigid as the principles of pure science, because they deal with human behaviour, which is never static, and technology keeps changing too — so the principles themselves must keep pace. That single idea explains most of the seven characteristics that follow.

Nature of Management Principles: Seven Characteristics

When a question asks “explain the nature of management principles,” it wants the seven characteristics below. Each row gives the meaning and a textbook example (NCERT, pp. 34–36). The derivation of these principles is a matter of science; their creative application is an art — which is why management is a learnable, teachable discipline (p. 33).

One follow-up question that always comes up: if principles are flexible, how are they still useful? Because universality and contingency work together. Universality says the principle applies everywhere; contingency says how much and in what form depends on the situation. The principle tells you what matters; the manager decides the application.

Principles also support the five functions of management — planning, organising, staffing, directing and controlling — because they guide the decisions taken while performing these functions (p. 34), a connection first introduced in the Chapter 1 notes on Nature and Significance of Management.

Why Principles Matter: From Better Decisions to Social Responsibility

The significance of principles is the “why study this?” section — six ways principles make management better (NCERT, pp. 37–39):

• Useful insights into reality: principles add to a manager’s knowledge, help learn from past mistakes, and solve recurring problems quickly — for example, delegating routine decisions and handling only exceptional ones (p. 37).
• Optimum utilisation of resources and effective administration: resources are limited, so they must give maximum benefit at minimum cost; principles let managers foresee cause and effect, avoid trial-and-error wastage, and bound managerial discretion so decisions stay free of personal bias (pp. 37–38).
• Scientific decisions: decisions rest on facts, logic and objective assessment — timely, realistic and measurable — instead of blind faith or prejudice (p. 38).
• Meeting changing environment requirements: flexible principles adapt to a dynamic environment; division of work has stretched into companies specialising in core competencies and outsourcing non-core activities — the world of BPO and KPO (p. 38).
• Fulfilling social responsibility: public awareness pushes businesses to meet social duties; today “equity” covers value to the customer, care for the environment and fair dealings with associates, not just wages (p. 39).
• Management training, education and research: principles are the core of management theory — the base for MBA/BBA curricula and management aptitude tests, and the seed of techniques like Operations Research, cost accounting, Just-in-Time, Kanban and Kaizen (p. 39).

The chapter’s example cases map onto these points like this:

Why not just manage by trial and error? Because resources are limited. Trial and error consumes time, material and money before you find what works; principles let a manager foresee the cause-effect relationship in advance, so the wastage associated with trial and error is avoided (pp. 37–38).

The environment that principles must adapt to is the subject of the notes on Business Environment, the chapter that follows this one.

Six Schools of Management Thought in Brief

Principles did not appear overnight. The chapter’s evolution box (pp. 31–32) groups management thought into six phases. Taylor and Fayol belong to phase 2, the Classical school — everything after them adds what the classical view left out.

Takeaway: the Classical school focused on technique and structure; the human side (phases 3–4) and the quantitative side (phase 5) came later, and modern management (phase 6) combines both with the idea that the right answer depends on the situation.

Taylor’s Scientific Management: Four Principles and One Mindset

Taylor worked in the era of mass production. He opposed the rule of thumb — managing by personal judgment in a trial-and-error way — and argued that a studied, standardised method should replace it everywhere (pp. 42, 44). His four principles are:

One honest edge case: the chapter summary (p. 64) also lists “Maximum, not restricted output” among Taylor’s principles, though the detailed discussion develops the four above.

The idea behind it is that workers and management should aim to enlarge output together rather than restrict it — exactly the mindset Taylor called mental revolution, the change of attitude from competition to cooperation on both sides, so that the surplus grows and is then shared (p. 51).

Techniques of Scientific Management: Eight Foremen, Four Studies, Two Standards

Principles are the “what”; techniques are the “how”. Taylor’s techniques put his principles to work on the shop floor (NCERT, pp. 47–54).

Functional foremanship

Taylor found that no single person had all the qualities of a good foreman — intelligence, education, tact, grit, judgment, special knowledge, manual dexterity, energy, honesty and good health. So he split the role into eight specialists under a planning incharge and a production incharge (p. 47):

Under this scheme each worker takes orders from all eight specialists in the related function of production. This is why Taylor did not value unity of command the way Fayol did — one of the sharpest differences between the two thinkers (p. 63).

Standardisation and simplification

Standardisation means setting standards for every business activity — process, raw material, time, product, machinery, methods or working conditions — which then act as benchmarks to be followed (p. 48). Its objectives include reducing a product line to fixed types and sizes, making parts interchangeable, and setting standards of excellence in materials and of performance by men and machines (p. 49).

Simplification means eliminating superfluous (unnecessary) varieties, sizes and dimensions of products. It saves the cost of labour, machines and tools, cuts inventories, gives fuller utilisation of equipment and raises turnover (p. 49). One line separates them: standardisation creates new standards; simplification removes unnecessary variety. Companies such as Nokia, Toyota and Microsoft have used both successfully (p. 49).

The four work studies

Taylor’s studies in modern life

Here is a modern translation of the four studies — the same logic runs inside everyday apps and routines:

The differential piece wage system completes the toolkit: workers who reach or exceed standard output are paid a higher rate per unit; those below standard get a lower rate. It is one of several calculations in the chapter, and it is worked out step by step in the next section.

Modern descendants of scientific management

The glossary on pages 53–54 connects Taylor’s ideas to today’s production vocabulary:

The One Calculation in This Chapter: Standard Time and Differential Wages

Method: Taylor’s Differential Piece Wage System, built on a Time Study. A time study fixes the standard time for a job; standard output follows; the differential wage rates then reward the efficient worker and pay the slow one less (pp. 50–51). The two formulas you need:

\[ \text{Standard output per day} = \frac{\text{available working minutes}}{\text{standard time per unit}} \]

\[ \text{Wages} = \text{units produced} \times \text{piece rate} \]

Original worked example — these numbers are new, not the textbook’s own 20-minute, ₹50/₹40 illustration (pp. 50–51):

Fayol’s 14 Principles of Management: The Complete List

Henri Fayol asked what a manager’s work consists of and what principles should guide it, while Taylor had concentrated on the worker’s task. His context first:

His 14 principles, with meanings and examples from NCERT, pp. 54–62:

Unity of Command vs Unity of Direction

The two principles most often swapped in answers. The textbook itself separates them on three bases (pp. 57–58):

Scalar chain and the gang plank

The scalar chain is the formal line of authority from the top to the bottom of an organisation. In the chapter’s example, head A has two lines below him: one runs B–C–D–E–F, the other L–M–N–O–P, and E and O sit at the same level.

If E must communicate with O, following the chain means climbing E–D–C–B–A and then descending A–L–M–N–O. But in an emergency, E can contact O directly through the gang plank — the direct E–O line that cuts the long route so communication is not delayed (p. 59).

The everyday version: a worker normally cannot walk straight to the CEO; the matter passes through the foreman, superintendent, manager and director — unless it is an emergency.

Memory device: three questions for 14 principles

To recall all 14 principles without a list, ask three questions. (This grouping is a memory aid, not a textbook classification.)

Fayol then and now: the principles themselves survive; only their interpretation has shifted. In today’s flatter, service-based organisations, authority is read as employee empowerment rather than manager empowerment, communication becomes less formal along a flatter scalar chain, and remuneration turns performance-based — “then” valued conformity, “now” rewards results (pp. 61–62).

Fayol and Taylor: Complementary, Not Contradictory

Both thinkers belong to the Classical school, and their work is complementary (p. 62). Fayol studied the manager’s job from the top down; Taylor studied the worker’s task from the shop floor up — which is why each needed the other. The differences come from those two vantage points.

This seven-row contrast (NCERT, pp. 62–63) is the backbone of the chapter’s difference-based exercises: a question that says “distinguish between Taylor and Fayol” wants exactly these seven bases, each in a complete sentence. The chapter summary closes by repeating that despite the differences, the two contributions are essentially complementary (p. 64).

Exam Notes: How to Structure Answers from the Textbook Exercises

The chapter’s exercises (pp. 65–68) come in four shapes. This is the writing pattern each shape expects; applying it to the actual questions is your revision task.

• Very short answers — give one precise defining sentence: name the principle or term and state what it is. No explanation, no example, no extra line.
• Short answers — use three parts: name and define, add one supporting point or consequence, then an example where the situation allows one.
• Long answers — use five parts: a brief introduction; point-wise explanation with each principle or technique defined separately; examples for each; and a short conclusion. For functional foremanship, show all eight roles under the two incharges; for work study, cover all four studies — method, motion, time and fatigue — never one or two.
• Case problems — follow three steps: read the situation and list every symptom; map each symptom to the principle it violates; then state corrective actions that directly answer each violation.

Symptom → Principle map for Fayol case problems

Most case symptoms repeat in a small set of patterns. Here is the central map:

For the chapter’s two-stage case sequence (Bhasin Ltd and Mukti Consultants, pp. 66–68), use a two-step logic: first identify which Fayol principle each symptom violates (use the map above); then decide which Taylor technique would repair the production problem — production planning, functional foremanship, work study, standardisation and the differential piece rate are the recommended changes named in the case.

The official NCERT PDF of Class 12 Business Studies Part I, Chapter 2 carries the full case text and exercises, so you can verify any page reference and practise against the exact wording.

Common Mistakes in This Chapter and How to Avoid Them

FAQs on Principles of Management

What is the difference between unity of command and unity of direction?

Unity of command means one employee receives orders from and is responsible to only one superior; its aim is to prevent dual subordination, and it affects the individual employee.

Unity of direction means each group of activities with the same objective must have one head and one plan; its aim is to prevent overlapping of activities, and it affects the entire organisation (pp. 57–58).

Why does functional foremanship give a worker eight bosses when unity of command says one boss?

Because Taylor found that no single person possessed every quality of a good foreman — intelligence, tact, grit, judgment, technical knowledge, energy and more — so he split the role into eight specialists, four for planning and four for execution (p. 47).

Fayol, writing about overall administration, insisted on one boss; Taylor, writing about the shop floor, chose specialisation over unity of command (p. 63).

What is the gang plank in Fayol’s scalar chain?

The gang plank is the direct line of communication between two people at the same level of the scalar chain, used in an emergency so that communication is not delayed (p. 59). In the chapter’s example, E normally reaches O through E–D–C–B–A–L–M–N–O; the gang plank lets E contact O directly when speed matters.

How are Taylor and Fayol complementary despite their differences?

Both belong to the classical school, but they worked at different levels. Taylor studied the worker’s task from the shop floor up, seeking the one best method and higher productivity. Fayol studied the manager’s job from the top down, seeking sound overall administration.

Since each covered what the other left out, and both are meant to be applied together, the chapter calls their contributions complementary (pp. 62–64).

What is mental revolution in scientific management?

Mental revolution is the complete change of attitude in both workers and management — from competition to cooperation. Both realise they need each other and aim to enlarge the surplus; management shares the gains while workers work hard and accept change (p. 51). For Taylor, this mindset — not any single technique — was the real substance of scientific management.

Why are management principles flexible if they are universal?

Universality means the principles apply to all types of organisations; flexibility means the degree and manner of application change with the situation. The two work together: a principle such as division of work applies everywhere, but how far work is divided varies from a small firm to a large one (pp. 34–35).
