Classical Approach• Forms the foundation for the field of management• The classical management thoughts are:

Scientific Management Administrative Theory Bureaucratic Management

Page 8: BASICS OF PRINCIPLES OF MANAGEMENT

Scientific Management

Early 1900s• It is defined as “that kind of management which

conducts a business or affairs by standards established, by facts or truths gained through systematic observation, experiment, or reasoning.”

• Major contributors: Frederick Winslow Taylor Frank and Lillian Gillbreth Henry L.Gantt Harrington Emerson

Page 9: BASICS OF PRINCIPLES OF MANAGEMENT

Principles of Scientific Management

• Develop of science for each work• Scientifically select, train and develop workforce• Division of labor (separation of planning function from doing

function)• Standardization of methods, procedures, tools and equipment• Use of time and motion study• Differential wage system• Cooperation between labor and management

Page 10: BASICS OF PRINCIPLES OF MANAGEMENT

10

Four Principles of Scientific Management

• Principles to increase efficiency:1. Study the ways jobs are performed now and determine new

ways to do them.• Gather detailed time and motion information.• Try different methods to see which is best.

2. Codify the new methods into rules.• Teach to all workers the new method.

3. Select workers whose skills match the rules.4. Establish fair levels of performance and pay a premium for

higher performance.• Workers should benefit from higher output

Page 11: BASICS OF PRINCIPLES OF MANAGEMENT

11

F. W Taylor• “Father of scientific management”(1878)

Two major managerial practices:

• Piece-rate incentive system

• Time-and-motion study

Page 12: BASICS OF PRINCIPLES OF MANAGEMENT

12

F.W. Taylor and Scientific Management

• Scientific Management– The systematic study of the relationships between people

and tasks for the purpose of redesigning the work process for higher efficiency.• Defined by Frederick Taylor in the late 1800’s to

replace informal rule of thumb knowledge.• Taylor sought to reduce the time a worker spent on each

task by optimizing the way the task was done.

Page 13: BASICS OF PRINCIPLES OF MANAGEMENT

13

Frank and Lillian Gillbreth

(1868-1924)• Motion study involves finding out the best sequence and

minimum number of motions needed to complete a task.• Explore new ways for eliminating unnecessary motions

and reducing work fatigue.• To them the ultimate aim of scientific management was to

help workers reach their full potential as human beings

Page 14: BASICS OF PRINCIPLES OF MANAGEMENT

14

Henry L.Gantt(1861-1919)• Well known for Task – and - bonus system -The Gantt

chart• If the worker completed the work fast, i.e., in less than the

standard time, he received a bonus. • It is a Simple daily balance chart that compares actual and

planned performances. • Introduced the concept of industrial responsibility.• Emphasis should be placed on services rather than on

profits.• Wider recognition of the human factor in management.

Page 15: BASICS OF PRINCIPLES OF MANAGEMENT

15

Harrington Emerson

• First to use the term “Efficiency Engineering”• “Right thing is done in the right manner , by

the right man ,at the right place ,in the right time.”

Page 16: BASICS OF PRINCIPLES OF MANAGEMENT

16

Limitations of Scientific Management

• Do not focus on the management of an organization from a manager’s point of view.

• people were “rational” and were motivated primarily by the desire for material gain.

• It also ignored the human desire for job satisfaction.• Fails to recognize the ideas and suggestions of workers.• Treat workers as machine.

Page 17: BASICS OF PRINCIPLES OF MANAGEMENT

17

Administrative Theory:

• It focused on principles that could be used by managers to coordinate the internal activities of organizations.

• Henri Fayol (1841-1925)

Page 18: BASICS OF PRINCIPLES OF MANAGEMENT

18

Six groups of work done in business enterprises

• Technical• Commercial• Financial• Security• Accounting• Managerial

Page 19: BASICS OF PRINCIPLES OF MANAGEMENT

19

Fayol’s Principles of Management

• Division of work: allows for job specialization. – noted jobs can have too much specialization

leading to poor quality and worker dissatisfaction.• Authority and Responsibility

– Fayol included both formal and informal authority resulting from special expertise.

• Unity of Command– Employees should have only one boss.

Page 20: BASICS OF PRINCIPLES OF MANAGEMENT

20

Fayol’s Principles of Management (cont’d)

• Line of Authority– A clear chain of command from top to bottom of

the firm.• Centralization

– The degree to which authority rests at the top of the organization.

• Unity of Direction– A single plan of action to guide the organization.

Page 21: BASICS OF PRINCIPLES OF MANAGEMENT

2–21

Fayol’s Principles of Management (cont’d)

• Equity– The provision of justice and the fair and impartial

treatment of all employees.• Order

– The arrangement of employees where they will be of the most value to the organization and to provide career opportunities.

• Initiative– The fostering of creativity and innovation by

encouraging employees to act on their own.

Page 22: BASICS OF PRINCIPLES OF MANAGEMENT

22

Fayol’s Principles of Management (cont’d)

• Discipline– Obedient, applied, respectful employees are necessary

for the organization to function.• Remuneration of Personnel

– An equitable uniform payment system that motivates contributes to organizational success.

• Stability of Tenure of Personnel– Long-term employment is important for the

development of skills that improve the organization’s performance.

Page 23: BASICS OF PRINCIPLES OF MANAGEMENT

23

Fayol’s Principles of Management (cont’d)

• Subordination of Individual Interest to the Common Interest– The interest of the organization takes precedence

over that of the individual employee.• Esprit de corps

– Comradeship, shared enthusiasm foster devotion to the common cause (organization).

Page 24: BASICS OF PRINCIPLES OF MANAGEMENT

24

Limitations• Too formal system.• Based on a few studies and they are not empirically

tested.• Based on the assumption that organizations are closed

system.• Insensitive to employees social and psychological

needs.

Page 25: BASICS OF PRINCIPLES OF MANAGEMENT

25

Bureaucratic ManagementWeber (1864-1920) Characteristics of Weber’s ideal Bureaucracy:• Work specification and division of labor• Abstract rules and regulations and well defined methods

for all types of works.• Formal and Impersonal relations among the members of

organization.• Interpersonal relations are based on positions and not on

personalities.• Hierarchy of organization structure.• Selection and promotion is based on technical

qualifications.

Page 26: BASICS OF PRINCIPLES OF MANAGEMENT

26

Limitations of Bureaucratic Management

• Not universally applicable to today’s complex organizations.

• Principle characteristic of bureaucracy changes in the global environment.

• Classical theorists ignored the problems of leadership, motivation, power or information relations.

• Excessive regulation may lead to unpleasant experiences and also to inefficient operations.

• Machine like treatment make employees unconcerned about the organization.

Page 27: BASICS OF PRINCIPLES OF MANAGEMENT

27

Neo-Classical approach

• Focused on the factors that affect human behavior at work.

• Human relation movement• Behavioral approach

Page 28: BASICS OF PRINCIPLES OF MANAGEMENT

28

Human relation movement• Elton Mayo : father of the human relations movement.• Hawthrone studies : a series of experiments on workers

productivity in 1924 at the Hawthrone plant of Western Electric company

• Contributions of Hawthrone studies:-• The way people were treated had an important impact on

performance.• Trend towards power equalization .• Conflict free inter-relations among the members of the

organizations.

Page 29: BASICS OF PRINCIPLES OF MANAGEMENT

29

Behavioral Approach• The behavioral approach to management emphasized

individual attitudes and behaviors and group processes, and recognized the significance of behavioral process in the workplace.

• Focused mainly on psychological needs as a means of achieving economic goals.

Page 30: BASICS OF PRINCIPLES OF MANAGEMENT

30

Abraham Maslow’s - Hierarchy of Needs Theory – substantially satisfied need no more motivates

Self Actualization

Esteem

Needs

Affiliation or Acceptance needs

Security or Safety Needs

Physiological Needs

Page 31: BASICS OF PRINCIPLES OF MANAGEMENT

31

Douglas McGregor – Theory X and YEither appropriate under different situations

Y – POSITIVE APPROACH Employees view work as natural play/rest. Persons accept responsibility

X – NEGATIVE APPROACH Employees dislike work, needs to be controlled and threatened

Page 32: BASICS OF PRINCIPLES OF MANAGEMENT

32

Douglas McgregorTheory X Theory YMost People dislike work Work is a natural activity like

play.Most People must be coerced and threatened before they work.

People are capable of self direction and self control

Most people prefer to be directed. They avoid responsibility and have little ambition.

People become committed to organizational objectives if they are rewarded in doing so.

Page 33: BASICS OF PRINCIPLES OF MANAGEMENT

33

Modern Approaches to Management

• Systems Approach

• Contingency Theory

• Management Science Approach

Page 34: BASICS OF PRINCIPLES OF MANAGEMENT

34

System approach

• Organizations can be visualized as systems• Inputs , transformation process , output and

feedback

Page 35: BASICS OF PRINCIPLES OF MANAGEMENT

35

Contingency approach

• Suggests the managers to develop skills to identify the important situational factors.

Page 36: BASICS OF PRINCIPLES OF MANAGEMENT

36

Management Science

It stresses the use of mathematical models and statistical methods for decision-making.

Another name is the Operations Research.

Page 37: BASICS OF PRINCIPLES OF MANAGEMENT

37

Emerging Approaches In Management Thought

William Ouchi, outlined new theory called Theory Z.

It is the blend of positive aspects of both American and Japanese management styles.

Quality Management is a management approach that directs the efforts of management towards bringing about continuous improvement in product and service quality to achieve higher levels of customer satisfaction and build customer loyalty.

Functions of Management

• Forecasting• Planning• Organizing• Staffing • Decision making• Directing• Controlling

Page 40: BASICS OF PRINCIPLES OF MANAGEMENT

40

Forecasting

• Forms the basis of planning the activities of an organization.

• Defined as an estimate of future events ,that can be obtained by systematically combining past and present data in a predetermined way and arrive at future data.

• Eg : sales forecast , production forecast

Page 41: BASICS OF PRINCIPLES OF MANAGEMENT

41

Planning

• Determined course of action for achieving a specific objective.

• Selecting mission and objectives and actions to achieve them.

• Consist of goals , policies ,procedures , rules , methods , budgets strategies and programmes

Page 42: BASICS OF PRINCIPLES OF MANAGEMENT

42

Types of Plans• Mission – Basic function or task for which the organization is existing• Objectives or Goals – Ends towards which an activity is aimed in

specific terms• Strategies – General programme of actions and deployment of

resources to attain comprehensive objectives• Policies – General statements or understandings which guide or

channel thinking in decision making• Procedures – Plans that establish a required method of handling future

activities• Rules – Spell out specific required action or non action, allowing no

discretion• Programmes – complex of goals , policies, procedures, rules, task

assignments, steps to be taken etc.• Budgets – Statement of expected results expressed in numerical terms

Page 43: BASICS OF PRINCIPLES OF MANAGEMENT

43

Steps in Planning

• Being aware of opportunities and threats• Analyze strengths and weakness• Setting objectives and goals• Developing premises and alternatives• Evaluating alternatives• Choosing alternatives• Selecting course of action• Formulating supporting plans

Page 44: BASICS OF PRINCIPLES OF MANAGEMENT

44

Organization

• Organizing involves process by which the structure and allocation of jobs is determined

• It is the formalized intentional structure of roles and positions

Page 45: BASICS OF PRINCIPLES OF MANAGEMENT

45

Organization definition

• Process of:– Identifying, classifying and grouping the work

to be performed– Defining and delegating responsibility and

authority– Establishing relationships for the purpose of

enabling people to work most effectively together in accomplishing objectives

Page 46: BASICS OF PRINCIPLES OF MANAGEMENT

46

Principles of Organization

• Objectives• Relationship of components• Responsibility• Authority• Span of control• Dividing, Grouping and specialization of work• Effective delegation• Communication• Defining line and staff functions• Balance• Stability• Flexibility

Page 47: BASICS OF PRINCIPLES OF MANAGEMENT

47

Organization structure• Systematic arrangement of people working for

the organization in order to achieve pre decided objectives

• Provides appropriate framework for authority and responsibility and relationship between components

• Represented in the form of an organization chart• Dimensions

– Vertical – hierarchy of managers and subordinates– Horizontal – basic departmentation

Page 48: BASICS OF PRINCIPLES OF MANAGEMENT

48

Organization structure

• Portrays graphically the structural relationship

• Structure depends on– Size of organization– Nature of product/service– complexity

Project Type Organization

• A separate division for one time activities

• Adopted for special one time activities

Page 58: BASICS OF PRINCIPLES OF MANAGEMENT

58

Matrix Type of Organization

• Combination of functional type and project type of organization

Page 59: BASICS OF PRINCIPLES OF MANAGEMENT

Page 60: BASICS OF PRINCIPLES OF MANAGEMENT

60

Span of control• Number of subordinates that report to an executive• Optimum 2 to 20• Small span – oversupervison• Large span – lack of supervision• Factors effecting span

– Training and experience of subordinates– Specialized and repetitive work– R&D and Maintenance– Requiring close supervision– Capacity of executive– Efficient control systems

Page 61: BASICS OF PRINCIPLES OF MANAGEMENT

61

Directing• Process by which the actual performance of

subordinates is guided towards the common goals of the enterprise

• Involves– Giving instructions to subordinates– Guiding subordinates to do the work– Supervise subordinates to make certain that work

done by them is as per the plans established

Page 62: BASICS OF PRINCIPLES OF MANAGEMENT

62

Directing involves

• Leadership• Communication• Motivation• supervision

Page 63: BASICS OF PRINCIPLES OF MANAGEMENT

63

Leadership• Leadership is the quality of the behavior of the

persons whereby they inspire confidence and trust in their subordinates , get maximum cooperation from them, and guide their activities in organized effort

• Three Types– Authoritarian – leader makes decisions and

commands– Democratic – Promotes participation of subordinates– Free reign or Laissez faire – minimum control

Page 64: BASICS OF PRINCIPLES OF MANAGEMENT

64

Communication

• Process by which ideas are transmitted received and understood by others for the purpose of achieving desired results

• Types– Upward– Downward– Horizontal

Page 65: BASICS OF PRINCIPLES OF MANAGEMENT

65

Motivation

• Inspiring the subordinates to do a work for achieving organization objectives effectively and efficiently

Page 66: BASICS OF PRINCIPLES OF MANAGEMENT

66

Factors contributing towards motivation

• Achievement – satisfaction of completion of a job

• Advancement – promotions

• GrowthLearning, new skills advancement

• Recognition – Acknowledgement of a job done well

• Responsibility and authority – to one’s job

Page 67: BASICS OF PRINCIPLES OF MANAGEMENT

67

Factors which demotivate

• Organization policy and administration• Job security• Interpersonal relations• Salary• Status • Supervision• Personal Life

Page 68: BASICS OF PRINCIPLES OF MANAGEMENT

68

Motivation and Theories of Motivation

• Inspiring the subordinates to do a work for achieving organizational objectives effectively and efficiently

• Theories of Motivation– Abraham Maslow’s - Hierarchy of Needs

Theory– Frederick Herzberg’s - two factor theory– David C McClelland - needs theory– Douglas McGregor – theory X and Y

David C McClelland – Three Needs TheoryIdentify the person type and motivate

NEED FOR POWER

•Great concern to Exercise influence and control•Forceful, outspoken, hard headed and demanding

NEED FOR AFFILIATION•Derive pleasure from being loved and avoid the pain of rejection•Enjoy sense of intimacy and understanding

NEED FOR ACHIEVEMENT

•Intense desire for success and fear of failure•Take difficult goals and take a realistic approach to risk

Page 71: BASICS OF PRINCIPLES OF MANAGEMENT

71

Controlling

• Monitoring the activities to make sure that objectives are being met.

• The initiation of corrective action to overcome problems

• Controlling process– Sets standards– Measures job performance– Takes corrective actions

Page 72: BASICS OF PRINCIPLES OF MANAGEMENT

72

Decision making

Page 73: BASICS OF PRINCIPLES OF MANAGEMENT

73

Decision making

• Conclusion of a process by which one chooses between two or more available alternative courses of action for the purpose of attaining goals

• All functions of management involve decision making

Page 74: BASICS OF PRINCIPLES OF MANAGEMENT

74

Steps in Decision making

• Defining problem• Searching for alternatives• Evaluating the alternatives• Selecting the alternative

Page 75: BASICS OF PRINCIPLES OF MANAGEMENT

75

Types of decisions

• Programmed and non programmed• Routine and strategic decisions• Organizational and personals decisions• Individual and group decisions

• Decision making process• decision making.pptx

Page 76: BASICS OF PRINCIPLES OF MANAGEMENT

76

Decision Making• Process by which a course of action is

consciously chosen from available alternatives for purpose of achieving objectives

• Decision making Classified into• Single stage – selecting alternatives on the

basis of available information at a point of time• Multistage – sequence of decisions in which

following each decision a chance event occurs which in turn influences further decisions

Page 77: BASICS OF PRINCIPLES OF MANAGEMENT

77

Single stage decision making steps

• Identification of various possible outcomes or states of nature or events for which the decision maker hasn’t got any control

• Identification of all courses of action or strategies where the decision maker has got control

• Determination of the payoff function which describe the consequences

• Choosing from various alternatives

Page 78: BASICS OF PRINCIPLES OF MANAGEMENT

78

Single Stage Decision making situations

• Decision making under certainty – Decision maker has clear idea about the outcomes

• Decision making under uncertainty – The decision maker can no way assess the probabilities of various states of nature

• Decision making under Risk – The decision maker chooses to consider several possible outcomes and the probabilities of occurrence can be stated

Page 79: BASICS OF PRINCIPLES OF MANAGEMENT

79

Example• An electrical machines dealer wants to take a

decision on how many capacitors are to be kept in stock to meet the customers demand

• Given• Selling price of one capacitor = Rs. 100• Cost price = Rs. 80• Disposal price of unsold capacitor = Rs. 30• Demand for a month = between 18 and 20 nos.• How much should be kept in stock for maximisng the

returns (profit)?

Page 80: BASICS OF PRINCIPLES OF MANAGEMENT

80

Analysis• Three Possible EVENTS • E1 = 18, E2 = 19, E3 = 20

• Three Possible STRATEGIES• S1 = 18, S2 = 19, S3 = 20

• To choose from three possible STRATEGIES with three possible EVENTS which are mutually exclusive

Page 81: BASICS OF PRINCIPLES OF MANAGEMENT

81

Payoff Functions

• Let D = Demand• Let Q = Quantity decided to purchase• Two situtaions D >= Q or D<Q• When D>=Q• Payoff = 100Q-80Q = 20Q• When D<Q• Payoff = [100D+30(Q-D)] – 80Q = 70D-

Decision Making Under Certainty

• Decision maker knows the exact demand

• Choose the strategy which gives the maximum Returns

Page 84: BASICS OF PRINCIPLES OF MANAGEMENT

Decision Making under UncertaintyPrinciple 1 – Laplace Equally likely Principle

• Consider all events as equally probable• Find out the expected mean value of

payoff for each strategy • Chose the strategy with highest expected

Decision Making under UncertaintyPrinciple 2 – MaxiMin or MiniMax Principle

• Adopted by pessimistic decision makers who are conservative in their approach

• Find the minimum payoff associated with each strategy

• Choose the maximum payoff from among these minimum payoff

• Choosing the best profit from the set of worst profits

Decision Making under UncertaintyPrinciple 4 – Hurwitz Principle

• Decision making between optimism and pessimism

• Define the index of optimism α which can take values from 0 (extreme pessimism) to 1 (extreme optimism)

• Multiply maximum profit by α and minimum profit by I – α and select the maximum of HC

• HC = (α) (Max Payoff) + (1-α)(Min Payoff)

Decision Making under Risk

• Decision maker chooses to consider several possible outcomes and the probability of their occurrence could be stated.

• Probabilities determined from past records.

• Probabilities are mutually exclusive and collectively exhaustive events

Decision Trees

• Multistage Decision making problems• Characterized by a sequence of decisions

in which following each decision a chance event occurs which in turn influences the next decision

• A decision tree is a graphical representation of the sequences of action event combinations available to the decision maker

Page 99: BASICS OF PRINCIPLES OF MANAGEMENT

99

Decision Trees

• Decision making criteria based on expectation principle, choosing the alternative that maximizes the expected profit

Example• Mary is a manager of a gadget factory. Her factory has been quite

successful the past three years. She is wondering whether or not it is a good idea to expand her factory this year. The cost to expand her factory is $1.5M. If she does nothing and the economy stays good and people continue to buy lots of gadgets she expects $3M in revenue; while only $1M if the economy is bad.

• If she expands the factory, she expects to receive $6M if economy is good and $2M if economy is bad.

• She also assumes that there is a 40% chance of a good economy and a 60% chance of a bad economy.

• (a) Draw a Decision Tree showing these choices.
