Operations Management and Operations Function
Foundations of Management Science and Operations Research
Management science is defined as the study and development of techniques for the formulation and analysis of management and related business problems. This field frequently utilizes operations research models to facilitate better decision-making processes. Operations research itself involves the application of specialized techniques derived from mathematics, statistics, engineering, and the physical sciences. These methodologies are applied to derive solutions for complex problems across diverse sectors, including business, government, industry, economics, and the social sciences.
A significant component of modern management is the use of quantitative methods. These methods employ mathematical models to reach a wide variety of business decisions, providing modern managers with a competitive edge. Managers do not necessarily need to possess great mathematical skills to benefit from these tools. Rather, familiarity allows a manager to ask the right questions, recognize when additional analysis is necessary, evaluate potential solutions, and make informed decisions based on empirical evidence.
In contrast to quantitative approaches, qualitative methods come in many varieties. Researchers focus on different sources of data, such as their own immediate experiences or the experiences of others. Understanding of others is sought through analyzing their speech or writing, their physical behaviors, and their products, including technology, artwork, and physical footprints.
Defining Production and Operations Management
Production is defined as the creation of goods and services. Production and operations management (POM) refers to the activities that transform resources into these finished goods and services. Operations management (OM) is specialized as the science and art of ensuring that goods and services are created and delivered successfully to customers. This discipline encompasses the design of goods, services, and the processes that create them, the day-to-day management of those processes, and the continual improvement of these products and systems.
The fundamental logic of operations management involves taking inputs, such as customers or materials, and moving them through a transformation process to create outputs in the form of components, goods, or services. Efficiently using these processes to transform inputs into valuable outputs allows an organization to seek a competitive advantage. Successful operations management results from the careful allocation of four primary resources: human resources, capital, information, and materials.
Functional Interdependence Within Organizations
Within any business organization, there are three critical functional areas that must interrelate to achieve success. Marketing is responsible for assessing consumer wants and needs and managing the selling and promotion of the organization’s goods or services. Operations focus on the production of the goods or providing the services offered. Finance and Accounting are responsible for securing financial resources at favorable prices and allocating those resources throughout the firm, as well as budgeting, analyzing investment proposals, and providing funds for operations.
Studying production and operations management is vital because it is one of the three critical parts of any organization and clarifies what operations managers do. Furthermore, the operations function is typically the costliest part of any organization. Understanding these processes helps explain how the goods and services society relies on are produced.
Process Management and Organizational Structure
Process management is a core aspect of operations management. A process consists of one or more actions that transform inputs into outputs. In essence, the central role of all management is process management. Business organizations are composed of many interrelated processes, which generally fall into three categories. Upper-management processes govern the operation of the entire organization, with examples including organizational governance and organizational strategy. Operational processes are the core processes that make up the value stream, such as purchasing, production, services, marketing, and sales. Supporting processes assist the core processes and include accounting, human resources, and information technology (IT).
Business processes, whether large or small, are composed of a series of supplier-customer relationships. Every business organization, department, and individual operation is both a customer of the previous step in the process and a supplier to the next step. Inputs into these processes include workers, managers, equipment, facilities, materials, land, and energy, while outputs consist of finished goods and services. This entire system is guided by information on performance.
The Scope and Role of the Operations Manager
The scope of operations management is broad and extends across the entire organization. Operations people are involved in product and service design, process selection, technological management, the design of work systems, location planning, facilities planning, and quality improvement. The operations function itself involves many interrelated activities, including forecasting, capacity planning, determining facilities and layout, scheduling, managing inventories, assuring quality, and motivating employees.
An operations manager’s primary function is to guide the production system by decision making. A production system refers to the way a firm acquires inputs and then converts and disposes of outputs. Operations managers are the individuals responsible for this transformation process from inputs to outputs. These managers can hold various titles, including Chief Operating Officer (COO), Hotel or Restaurant Manager, Vice President of Manufacturing, Customer Service Manager, Plant Manager, Field Services Manager, or Supply Chain Manager.
System Design and System Operation Decisions
Operations managers make two principal types of decisions: system design decisions and system operation decisions. System design decisions are typically strategic and require a long-term commitment of resources. These decisions determine the parameters of system operation and include capacity planning, facility location, facility layout, product and service planning, and the acquisition and placement of equipment.
System operation decisions are generally tactical and operational in nature. These involve the management of personnel, inventory management and control, scheduling, project management, and quality assurance. While operations managers spend more time on system operation decisions than any other decision area, they still maintain a vital stake in system design because design choices provide the constraints under which operations must function.
Contributions to Society and Core Organizational Foundations
Operations management contributes significantly to society by providing a higher standard of living through increased productivity and lower costs for goods and services. It leads to better quality goods and services as competition increases quality standards. Furthermore, it demonstrates concern for the environment through recycling and air/water quality initiatives and improves working conditions through better job design and employee participation.
The foundations of operations management rest on several key pillars. Planning involves constant forecasting and adjustment to optimize processes. Process management requires having strong, repeatable processes for production. Efficiency demands that managers troubleshoot bottlenecks, inadequate resources, and downtimes to create optimal flow. Cost control is vital because production is typically the largest part of a company's cost structure. Quality management is necessary to maintain customer satisfaction and the company's reputation. Continuous improvement ensures companies consistently seek better ways of doing things to remain competitive. Technology acts as the underlying enabler that keeps a company ahead of the curve. Ultimately, if these foundations are executed properly, they lead to strong profitability and a better bottom line.
Key Operations Management Concepts and Implementation
When a new product is introduced, process design determines the best way to produce it by charting detailed steps. Inventory management is tightly controlled to keep costs down and avoid unnecessary production, with inventory levels often adjusted every four weeks and managed in an inventory system according to these counts. Scheduling and capacity management involve creating production schedules to ensure enough product is available for retail and wholesale customers, taking into account current inventory and total production capacity.
Quality management ensures that goods and services are reliable and perform correctly according to customer expectations. Every product is inspected against high standards. If a product fails to conform—for instance, due to the wrong color, improper weight, size, shape, or faulty packaging and labeling—it is removed from inventory to determine where the process broke down and to initiate corrective action. Managers also focus on responsiveness to customers, reacting quickly and correctly to needs as they arise. Efficiency is defined as the amount of input required to produce a given output; the less input required, the lower the cost and waste.
Productivity Measurement and Analysis
Productivity is defined as the ratio of outputs to inputs, expressed by the formula:
There are three main types of measurement. Partial measures look at output relative to a single input. Multi-factor measures consider output relative to multiple inputs. A total measure evaluates output relative to total inputs. For example, labor productivity can be calculated as:
Alternatively, a unitless figure can be calculated using prices and wages:
Consider the following productivity comparison: This week, service employees used a total of hours of labor to process insurance forms. Last week, the same crew used hours of labor to process forms. To determine if productivity is increasing or decreasing, we calculate the rates:
Last week:
This week:
In this scenario, productivity is decreasing.
Comparison of Goods and Services
A good is a physical product that can be seen, touched, or consumed. Examples include oranges, flowers, televisions, soap, airplanes, fish, furniture, coal, lumber, personal computers, paper, and industrial machines. In contrast, a service is any primary or complementary activity that does not directly produce a physical product.
Despite their differences, goods and services share three key similarities. First, they both provide value and satisfaction to customers who purchase and use them. Second, they can both be standardized or customized to individual wants and needs. Finally, a process creates and delivers each, making operations management a critical skill for both.
Factors of Differentiation and Current Challenges
There are several key differences between goods and services. Goods typically feature low customer contact, high uniformity of input, low labor content, and high uniformity of output. The output of goods is tangible, productivity measurement is easy, and there is a high opportunity for quality assurance to correct problems. Goods usually involve significant inventory, work evaluation is easier, and designs are usually patentable.
Services feature high customer contact, low uniformity of input, high labor content, and low uniformity of output. Service outputs are intangible, making productivity measurement difficult. There is a low opportunity for quality assurance before delivery, as production and delivery often happen simultaneously. Services involve little inventory, and evaluation of work is more difficult. Furthermore, service designs are usually not patentable.
Modern operations management faces several current challenges, including the integration of new technology, the impacts of globalization, changing job designs to meet modern needs, maintaining high quality, and the complexities of global manufacturing.
