UNIT-I: Principles of Management

Q1. Discuss Taylor's Scientific Management Theory.

F.W. Taylor, known as the Father of Scientific Management, proposed replacing rule-of-thumb methods with scientific, standardized methods derived from careful study of work.

Principles of Scientific Management

Science, not rule of thumb — replace guesswork with scientifically studied methods.

Harmony, not discord — cooperation between management and workers.

Cooperation, not individualism — mutual trust between labour and management.

Development of each person to their greatest efficiency and prosperity.

Elements

Time and motion study

Standardisation of tools and methods

Scientific selection and training of workers

Differential piece-rate wage system

Functional foremanship

Q2. Describe the concept of Herzberg's Two-Factor Theory.

Frederick Herzberg proposed that job satisfaction and dissatisfaction are influenced by two distinct sets of factors, not opposite ends of a single scale.

Hygiene Factors (prevent dissatisfaction)

Salary, company policy, working conditions, job security, supervision, interpersonal relations.

Motivator Factors (create satisfaction)

Achievement, recognition, responsibility, growth, advancement, the work itself.

Absence of hygiene factors causes dissatisfaction, but their presence alone does not motivate; true motivation comes from the motivator factors.

Q3. Summarize the Nature and Importance of Management.

Nature of Management

A goal-oriented, continuous and universal process

Both an art and a science

A group activity carried out through people

A dynamic and intangible force

Importance of Management

Achieves organizational goals efficiently

Optimum utilisation of resources

Reduces costs and increases productivity

Establishes sound industrial relations

Facilitates growth and expansion of the organisation

Q4. Explain Different Levels of Management with Examples.

Top Management

Frames overall policy and objectives — e.g. Board of Directors, CEO, Managing Director.

Middle Management

Implements top management's plans within their department — e.g. Departmental Managers, Plant Managers.

Lower / Supervisory Management

Directly supervises workers and day-to-day operations — e.g. Foremen, Supervisors, Section Officers.

Q5. Explain Line and Staff Organization Structure.

In a line and staff organisation, line authority flows vertically (General Manager → departmental line managers → foremen) and carries decision-making power, while staff positions (e.g. HR, legal, quality advisors) provide specialised advice without direct command authority.

Advantages

Combines the discipline of a line structure with expert staff guidance.

Limitation

Possible conflict between line and staff over authority.

Q6. Discuss Different Needs Identified in Maslow's Hierarchy with an Example.

Physiological

Basic survival needs — e.g. a worker's need for adequate salary to afford food and shelter.

Safety

Job security and safe working conditions — e.g. permanent employment, PF/insurance.

Social

Belonging and friendship — e.g. team-based work, informal groups.

Esteem

Recognition and status — e.g. 'Employee of the Month' award.

Self-Actualisation

Realising one's full potential — e.g. an engineer leading an innovative R&D project.

Q7. Summarize the Functions of Management.

Planning: Deciding objectives in advance and the course of action to achieve them.

Organizing: Arranging resources and activities into a coherent structure.

Staffing: Recruiting, selecting and placing the right people in the right jobs.

Directing: Guiding, supervising and motivating subordinates.

Controlling: Measuring performance against standards and correcting deviations.

Q8. Describe the Concept of Departmentation and Decentralization.

Departmentation

The process of grouping activities into units/departments (e.g. by function, product, territory or customer) to make an organisation manageable.

Decentralization

The systematic delegation of authority to lower levels of management, spreading decision-making power away from a single centre so that decisions can be made closer to where action is needed.

Q9. Explain Matrix Organization Structure.

A matrix structure combines functional departmentation with project/product-based departmentation, so an employee reports to both a functional manager and a project manager simultaneously — commonly used in engineering and construction firms handling multiple projects.

Advantage

Efficient use of specialised resources across projects.

Limitation

Dual reporting can create conflicting instructions (violates unity of command).

Q10. Classify Organization Structures with Examples.

Line Organization — direct chain of command, e.g. small manufacturing unit.

Line and Staff Organization — line authority plus specialist advisors, e.g. mid-size company with an HR advisor.

Functional Organization — grouped by specialisation (Taylor's concept), e.g. separate heads for production, quality, maintenance.

Matrix Organization — dual reporting across function and project, e.g. engineering consultancy.

Divisional Organization — grouped by product/region, e.g. an FMCG company with separate divisions for soaps, foods, cosmetics.

Q11. Define Management and Explain its Functions.

Management is the process of planning, organizing, staffing, directing and controlling organizational resources (men, materials, machines, money) to achieve stated objectives efficiently and effectively.

Functions

Planning, Organizing, Staffing, Directing, Controlling — as detailed in Q7 above.

Q12. Illustrate the Principles of Management as Outlined by Henry Fayol.

Division of Work

Authority and Responsibility

Discipline

Unity of Command

Unity of Direction

Subordination of Individual Interest to General Interest

Remuneration

Centralization

Scalar Chain

Order

Equity

Stability of Tenure

Initiative

Esprit de Corps

These 14 principles remain broadly applicable guidelines rather than rigid laws, adaptable to organisational context.

Q13. Distinguish Between Delegation of Authority and Responsibility.

Basis	Authority	Responsibility
Meaning	The right to give orders and make decisions	The obligation to perform an assigned task
Flow	Flows downward from superior to subordinate	Flows upward — subordinate is accountable to superior
Can it be delegated?	Yes, fully delegable	Cannot be fully delegated — ultimate responsibility remains with the superior
Nature	A right/power	An obligation/duty

UNIT-II: Method Study, Work Study & Plant Layout

Q14. Discuss the Procedure of Method Study.

Method study (also called SREDIM) follows six systematic steps to find the most economical way of doing a job, as shown above: Select, Record, Examine, Develop, Install and Maintain.

Q15. What are the Principles of Good Plant Layout.

Principle of integration — integrates men, materials, machines and services smoothly.

Principle of minimum movement — minimises material handling and travel distance.

Principle of flow — ensures smooth, uninterrupted flow of work.

Principle of cubic space utilisation — uses vertical as well as floor space.

Principle of safety and satisfaction — provides safe, comfortable working conditions.

Principle of flexibility — allows easy rearrangement for future changes.

Q16. Explain Objectives and Procedure of Method Study.

Objectives

Improve processes and procedures

Improve workplace layout and design

Reduce unnecessary fatigue and material handling

Improve utilisation of materials, machines and manpower

Develop a safer working environment

Procedure

Follows the same SREDIM steps described in Q14 (Select, Record, Examine, Develop, Install, Maintain).

Q17. Summarize the Objectives of a Good Plant Layout.

Minimise material handling and transportation cost

Effective utilisation of available floor space

Smooth and continuous flow of production

Increased employee safety and morale

Flexibility for future expansion or changes in product/process

Reduced production time and work-in-progress

Q18. Compare Method Study and Work Study.

Basis	Method Study	Work Study
Scope	A component of work study — focuses on how a job is done	A broader term comprising both method study and work measurement
Purpose	Finds the best method of doing a job	Improves productivity and sets standard time for the job
Output	An improved, standardised method	An improved method plus a standard time for it

Q19. Illustrate Various Types of Process Charts.

Outline Process Chart — shows only main operations and inspections in sequence.

Flow Process Chart — records all events (operations, transports, inspections, delays, storage) for one item, worker or equipment.

Two-Handed Process Chart — records the activities of a worker's left and right hand.

Multiple Activity Chart — records activities of several workers/machines against a common time scale.

Q20. Summarize the Benefits of Work Study.

Increases productivity without major capital investment

Reduces production cost and cycle time

Sets fair, scientifically-determined standard times for wage incentive schemes

Improves working methods and reduces worker fatigue

Aids in production planning and control

Improves plant layout and material handling

Q21. Discuss Objectives and Procedure to Conduct Work Measurement in an Organization.

Objectives

Determine standard time for a job

Compare alternative methods of work

Set a basis for incentive wage schemes

Aid production planning and manpower budgeting

Procedure

Select the job/task to be measured

Record all relevant data about the task and conditions

Examine the recorded data critically

Measure the observed time using a stopwatch or other technique

Apply rating and allowances to compute basic and standard time

Define the standard time and issue it for use

Q22. Differentiate Between Job, Batch and Mass Production.

Basis	Job Production	Batch Production	Mass Production
Quantity	Single unit, made to order	Limited batches of identical items	Continuous, very large volumes
Variety	High variety, low volume	Moderate variety	Low variety, high standardisation
Example	Custom furniture, ships	Bakery products, garments	Automobiles, FMCG products
Layout	Process/fixed-position layout	Process layout	Product layout

Q23. Illustrate Process Layout with a Suitable Sketch.

In process layout (functional layout), machines performing similar operations are grouped together (e.g. all lathes in one section, all milling machines in another). It suits low-volume, high-variety (job/batch) production and offers flexibility, though material handling cost is higher due to varied routing.

Q24. What is Plant Layout? Explain its Types.

Plant layout is the physical arrangement of machinery, equipment and facilities within a factory to enable the smoothest possible flow of materials and operations at the lowest cost.

Types

Process (Functional) Layout — similar machines grouped together; suited to job/batch production.

Product (Line) Layout — machines arranged in the sequence of operations; suited to mass production (see diagram in Q23).

Fixed-Position Layout — the product stays in one place and resources are brought to it, e.g. shipbuilding, large aircraft assembly.

Combination/Hybrid Layout — a mix of process and product layout used in complex manufacturing.

Q25. Describe the Factors Influencing Plant Location.

Proximity to raw materials

Availability of labour and skilled manpower

Nearness to markets and customers

Availability of transport and communication facilities

Availability of power, water and other utilities

Government policies, taxation and incentives

Climatic conditions and topography

Availability of land at reasonable cost

Q26. Discuss Work Measurement and the Equipment Used.

Work measurement is the application of techniques to determine the time a qualified worker takes to carry out a specified job at a defined level of performance — it establishes the standard time for a task.

Techniques / Equipment

Stopwatch time study — most common direct method using a stopwatch and rating.

Work sampling — statistical sampling of activities at random intervals.

Predetermined Motion Time Systems (PMTS) e.g. MTM, Work-Factor — pre-established time values for basic motions.

Synthetic data / standard data — built from previously recorded elemental times.

Analytical estimating — based on experience for non-repetitive jobs.

Q27. Discuss the Applications of Process Charts in Work Study.

Recording the existing method clearly and objectively for analysis

Identifying non-value-adding activities (delays, unnecessary transport/storage)

Comparing alternative methods before selecting the best one

Communicating a proposed new method to management and workers

Serving as a basis for redesigning plant layout and workflow

Training new operators in the correct method
