Industrial Management (NHU-601)
Complete Section-Wise Explanation – B.Tech Semester VI
Introduction to the Subject
Industrial Management is a foundational subject that teaches how industries and organizations are planned, organized, directed, and controlled to achieve maximum efficiency with minimum resources. Unlike purely technical subjects, Industrial Management focuses on people, productivity, quality, cost control, inventory, decision-making, and organizational structure.
This subject is extremely important for engineers because, in real life, engineers are not only technical experts but also managers, planners, and decision-makers.
The question paper is divided into three sections: A, B, and C, and all sections must be attempted as per instructions.
SECTION A – Basic Definitions & Core Concepts
Pattern:
Attempt all questions
10 questions × 2 marks = 20 marks
Nature of Section A
Section A checks your basic conceptual clarity. Answers are short but must be precise, correct, and meaningful. These questions are scoring if definitions are clear.
Explanation of Section A Topics
Productivity and Its Formula
Productivity is the ratio of output produced to the input used. It measures how efficiently resources like labor, capital, and materials are utilized.
Productivity = Output / Input.
Applications of Industrial Management
Industrial management is applied in planning production, controlling costs, managing manpower, improving quality, reducing waste, increasing profitability, and ensuring smooth organizational functioning.
Uses of Productivity Measurement
Productivity measurement helps in performance evaluation, cost reduction, comparison of departments, planning improvements, wage fixation, and increasing competitiveness.
Symbols of Process Charts
Process charts use symbols such as operation, inspection, transportation, delay, and storage to visually represent work flow.
Difference Between Inventory and Stock
Inventory includes raw materials, work-in-progress, and finished goods, while stock usually refers only to finished goods ready for sale.
Method Study and Its Objectives
Method study is the systematic recording and critical examination of existing methods to improve efficiency. Its objective is to reduce work content, eliminate waste, and improve productivity.
Quality Costs
Quality costs include prevention costs, appraisal costs, internal failure costs, and external failure costs. These costs help organizations understand the financial impact of quality.
Statistical Quality Control (SQC)
SQC uses statistical techniques to monitor and control quality. It helps detect variations in processes and maintain consistent quality levels.
Just-In-Time (JIT)
JIT is an inventory management approach where materials are received only when needed, reducing storage costs. For example, automobile manufacturers using JIT receive parts just before assembly.
Concept and Parameters of Quality
Quality refers to fitness for use. Parameters include performance, reliability, durability, aesthetics, serviceability, and conformance to standards.
SECTION B – Management Theories, Production & Quality Control
Pattern:
Attempt any five parts
5 × 10 marks = 50 marks
Nature of Section B
This section requires descriptive answers written in paragraph form. Students must explain concepts logically, sometimes with derivations and examples.
Explanation of Important Section B Questions
Scientific Approach to Management
The scientific approach to management, proposed by F.W. Taylor, emphasizes systematic analysis of work, standardization, time study, and incentive-based wages. It improves productivity by replacing guesswork with scientific methods, leading to better planning and worker efficiency.
Production Management vs Operations Management
Production management focuses mainly on manufacturing activities, whereas operations management includes both manufacturing and service industries.
Intermittent production deals with customized products in batches, while continuous production is used for mass production with standardized processes.
Types of Ownership and Liability
Ownership types include sole proprietorship, partnership, joint stock company, and public enterprises.
Limited liability restricts owner’s loss to invested capital, while unlimited liability makes owners personally responsible for business debts.
Inventory Costs and EOQ Derivation
Inventory costs include ordering cost, holding cost, and shortage cost.
The Economic Order Quantity (EOQ) model minimizes total inventory cost by balancing ordering and carrying costs under assumptions of constant demand and no stock-outs.
Control Charts – Variables and Attributes
Variable charts (X-bar, R charts) are used for measurable data, while attribute charts (p, np, c charts) are used for defect counts. These charts help identify whether a process is under statistical control or not.
SECTION C – Long Answer & Analytical Questions
Pattern:
Attempt any one part from each question
5 questions × 10 marks = 50 marks
This section carries maximum weightage and strongly affects final scores. Answers must be well-structured, explanatory, and clear.
Question 3
Inventory Control Techniques
Inventory control techniques like ABC analysis, EOQ, JIT, VED, and FSN analysis help organizations maintain optimum inventory levels, reduce costs, and avoid shortages.
Control Charts for Variables
Control charts are graphical tools used to monitor process variation. Variable control charts track changes in measurable characteristics such as weight or length.
Question 4
Historical View of Industrial Management
Industrial management evolved from traditional management to scientific management, human relations movement, and modern management theories. Recent developments include automation, ERP, lean manufacturing, and digital management systems.
Importance of EOQ
EOQ helps organizations decide the most economical order size, reducing inventory costs and ensuring uninterrupted production.
Question 5
Administrative vs Bureaucratic Management
Administrative management focuses on principles like planning and coordination, while bureaucratic management emphasizes formal rules, hierarchy, and authority.
Acceptance Sampling
Acceptance sampling determines whether to accept or reject a batch based on sample inspection. Single, double, and sequential sampling methods vary in inspection effort and decision speed.
Question 6
Supply Chain Concept
A supply chain is a network of suppliers, manufacturers, distributors, and retailers working together to deliver products to customers efficiently.
Total Quality Management (TQM)
TQM is a customer-focused approach involving continuous improvement. Statistical tools like Pareto charts, cause-effect diagrams, and control charts are used for quality improvement.
Question 7
Production Planning and Control (PPC)
PPC ensures smooth production flow by planning, routing, scheduling, dispatching, and follow-up. Its objective is to achieve timely production with optimum resource utilization.
Joint Stock Company Advantages
Joint stock companies overcome limitations of capital and management through large capital base, professional management, continuity, and limited liability.
