Production & Operations Management: Concepts, Scope and Production Manager Functions & Responsibilities
What is Production & Operations Management?
Production is the conversion of inputs into outputs. It involves transforming resources (Men, Machines, Materials, Money, Methods, and Management – the 6 Ms) into finished goods or services.
Operations Management (OM) is broader.
It simply means managing everything that helps a company produce goods or deliver services.
It takes care of all the resources needed to make products or provide services.
It controls the entire conversion process — where inputs (like materials, machines, labor) are turned into outputs (goods or services).
Key Definition:
“Operations Management is the management of an organization’s productive resources or its production system, which converts inputs into the organization’s products and services.”
Examples:
Making physical products → Manufacturing companies
Providing services → Banks, hospitals, hotels, etc.
In short: OM manages how a company’s products or services are created and delivered in the most efficient way.
The Transformation Process
Production is like a system where something goes in, gets changed, and comes out as a finished product or service.
1. Inputs (What we use)
These are the things needed to start the work:
Men – People/workers
Machines – Equipment
Materials – Raw items
Money – Funds required
Methods – How the work is done
Management – People who plan and control the work
2. Transformation Process (What happens inside)
This is the actual working or converting activity, such as:
Cutting
Mixing
Assembling
Cooking
Serving
Basically, turning inputs into final products or services.
3. Outputs (What comes out)
Goods → Things produced (tables, phones, clothes)
Services → Work done for customers (banking, healthcare, teaching)
4. Feedback / Control (Checking and improving)
This step is about monitoring the process:
Are products good quality?
Are we working efficiently?
If something is wrong, we adjust the process to improve.
Difference: Production Management vs. Operations Management
While often used interchangeably, there is a distinct difference in scope:
| Basis | Production Management | Operations Management |
| Scope | Narrower. Focuses mainly on manufacturing goods. | Broader. Focuses on both manufacturing goods and delivering services. |
| Output | Tangible goods (Cars, Soaps, Phones). | Tangible goods + Intangible services (Banking, Consulting, IT Support). |
| Timeframe | Often project-based with a completion date (e.g., building a dam). | Ongoing and continuous (e.g., managing daily IT support). |
| Example | A factory manager ensuring 500 cars are assembled. | An operations manager ensuring a call center runs smoothly 24/7. |
Analogy: Production Management is like building a house (a project with an end). Operations Management is like running a hotel (a daily, ongoing process of service delivery).
Scope of Production Management
The scope of production management is vast and can be divided into two main categories:
1. Designing the Production System
This is about planning how the production will work.
Product Design
Deciding what product to make and how it should look or function.
Facility Location
Choosing where the factory or plant should be built.
Plant Layout
Organizing machines, departments, and work areas in the best way for smooth workflow.
Material Handling
Planning how materials will move inside the factory (trolleys, conveyors, forklifts, etc.).
2. Analysis & Control of Production
This is about managing and controlling the actual production work.
Production Planning
Deciding when work will be done and what resources are needed.
Production Control
Making sure work is done on time, and checking the progress regularly.
Inventory Control
Managing raw materials, work-in-progress, and finished goods so there is no shortage or excess.
Quality Control
Checking products/services to ensure they meet quality standards (using tools like Statistical Quality Control).
Interface with Other Functions
Production cannot work in isolation. It interfaces with:
Marketing: To know what to produce based on customer needs and when to deliver.
Finance: For capital to buy machines and budget for costs.
Human Resources (HR): For hiring skilled labor and training.
Design/Engineering: For product specifications and new product development.
Who is a Production Manager?
A Production Manager is the person responsible for planning, coordinating, and controlling the manufacturing processes. They ensure that goods and services are produced efficiently, at the right cost, right quality, and right time.
They are the bridge between the strategic goals of the company and the actual operational output on the factory floor.
Functions of Production Management
Production management functions are viewed as a continuous management process involving three key activities:
1. Planning
This involves establishing a course of action for the future.
Product Planning: Deciding on the product mix.
Facility Planning: Designing the layout and location.
Process Planning: Designing the conversion process (how inputs become outputs).
2. Organizing
This involves establishing a structure of tasks and authority.
Assigning authority and responsibility to supervisors and workers.
Creating an organizational structure that supports efficient production.
3. Controlling
This ensures that actual performance matches the planned performance.
Quality Control: Checking for defects.
Cost Control: Keeping production costs within budget.
Schedule Control: Ensuring delivery deadlines are met.
Key Roles & Responsibilities of a Production Manager
The Production Manager wears many hats. Their key responsibilities include:
Forecasting: Predicting future demand to plan production schedules.
Order Management: Processing production orders and issuing instructions to the shop floor.
Maintenance: Ensuring machines and equipment are maintained to prevent breakdowns.
Inventory Management: Managing stock levels of raw materials to ensure production never stops due to shortages.
Quality Assurance: Implementing quality checks to minimize rejections and waste.
Cost Reduction: Constantly looking for ways to produce more with less (minimizing wastage, optimizing manpower).
Team Leadership: Motivating the workforce and handling labor issues on the floor.
Objectives of Production Management
The ultimate goal is to produce quality goods and services at the right price and right time. This is achieved through:
Optimal Resource Use: Maximizing the utility of men, machines, and materials.
Minimizing Wastage: Reducing scrap and idle time.
Productivity: Improving the ratio of Output to Input.
Customer Confidence: delivering reliable products consistently.
Automation in Production
A modern Production Manager must also manage Automation.
Definition: Automation is the self-controlling operation of machinery that reduces or dispenses with human control.
Role: It increases speed and precision but requires the manager to oversee technical maintenance and workforce upskilling.
