Unit 1: Production Concepts
Production Concepts
Production is the process of converting raw materials into finished goods or services using various resources such as manpower, machines, and technology. It plays a crucial role in any business because it ensures the availability of goods and services to meet customer needs.
Meaning of Production and Operations Management (POM)
Production and Operations Management (POM) is the process of planning, organizing, directing, and controlling the resources and activities required to produce goods or services.
- Production Management deals with manufacturing and physical products.
- Operations Management includes both manufacturing and service sectors (like banks, hospitals, hotels, etc.).
Nature of Production and Operations Management:
Scope of Production and Operations Management
Difference Between Production and Operations Management
- Production Management is a subset of Operations Management.
- Operations Management is more comprehensive, dealing with both production of goods and delivery of services.
Meaning of Productivity
Productivity refers to the efficiency with which inputs (like labor, materials, and capital) are converted into outputs (goods or services). It shows how well resources are being utilized to produce the desired output.
Formula:
Productivity = Output / Input
Factors Affecting Productivity
Productivity Measurement
A. Single-Factor Productivity (SFP): Measures output against one input only (e.g., labor, capital, or material). Example: Labor Productivity = Output / Labor Hours
B. Multi-Factor Productivity (MFP): Measures output against a combination of inputs (like labor + capital + materials). Example: MFP = Output / (Labor + Capital + Material inputs)
Work Study
Objective: To increase productivity and reduce unnecessary effort, time, and cost.
Components of Work Study
Method Study
Goal: Find the best way to do a job.
Steps in Method Study:
- Select the work to be studied.
- Record all relevant facts about the current method (e.g., using flowcharts).
- Examine the facts critically (Why? What? Where? When? Who? How?).
- Develop an improved method.
- Evaluate and select the best method.
- Install the new method.
- Maintain the method by training workers and regular follow-up.
Work Measurement
Work Measurement is the technique used to determine the time required to complete a job by a qualified worker at a defined level of performance.
Techniques of Work Measurement
Production Technology
Types of Manufacturing Processes
Comparison of Manufacturing Processes
The choice of manufacturing process depends on factors like product type, production volume, cost, time, and customer demand.
