WHAT IS OPERATIONS MANAGEMENT § The management of systems or processes that creates value WHAT IS OPERATIONS MANAGEMENT § The management of systems or processes that creates value in the form of goods and services by transforming inputs into desired outputs § The design, operation and improvement of the systems or processes that create goods and/or provide services 3

THE OPERATIONS FUNCTION ü Operations as a transformation process ü Operations as a basic THE OPERATIONS FUNCTION ü Operations as a transformation process ü Operations as a basic function ü Operations as the technical core

THE TRANSFORMATION PROCESS Value-Added Inputs • Land • Materials • Labor • Management • THE TRANSFORMATION PROCESS Value-Added Inputs • Land • Materials • Labor • Management • Capital • Information Transformation/ Conversion Process Outputs • Goods • Services Feedback Control Feedback = measurements taken at various points in the transformation process Control = The comparison of feedback against previously established standards to determine if corrective action is needed.

WHAT IS VALUE ADDED? The essence of operations function is to add value during WHAT IS VALUE ADDED? The essence of operations function is to add value during the transformation process Value added is the difference between the cost of intputs and the value or price of outputs.

PROCESS VARIATION Four Sources of Variation: Variety of goods or services being offered The PROCESS VARIATION Four Sources of Variation: Variety of goods or services being offered The greater the variety of goods and services offered, the greater the variation in production or service requirements. Structural variation in demand These are generally predictable. They are important for capacity planning. Random variation Natural variability that is present in all processes. Generally, it cannot be influenced by managers. Assignable variation Variation that has identifiable sources. This type of variation can be reduced, or eliminated, by analysis and corrective action. Variations can be disruptive to operations and supply chain processes. They may result in additional costs, delays and shortages, poor quality, and inefficient work systems. 57

ROLE OF THE OPERATIONS MANAGER The Operations Function consists of all activities directly related ROLE OF THE OPERATIONS MANAGER The Operations Function consists of all activities directly related to producing goods or providing services. A primary function of the operations manager is to guide the system by decision making. – System Design Decisions – System Operation Decisions 61

SYSTEM DESIGN DECISIONS System Design Decisions – Capacity – Facility location – Facility layout SYSTEM DESIGN DECISIONS System Design Decisions – Capacity – Facility location – Facility layout – Product and service planning – Process planning – Technology planning – Acquisition and placement of equipment These are typically strategic decisions that require • long-term commitment of resources • Determine parameters of system operation 62

SYSTEM OPERATION DECISIONS System Operation – Management of personnel – Inventory management and control SYSTEM OPERATION DECISIONS System Operation – Management of personnel – Inventory management and control – Scheduling – Project management – Quality assurance Operations managers spend more time on system operation decision than any other decision area but they still have a vital stake in system design 63

OPERATIONS MANAGEMENT AND DECISION MAKING Most operations decisions involve many alternatives that can have OPERATIONS MANAGEMENT AND DECISION MAKING Most operations decisions involve many alternatives that can have quite different impacts on costs or profits Typical operations decisions include: What resources are needed, and in what amounts? When: When will each resource be needed? When should the work be scheduled? When should materials and other supplies be ordered? Where: Where will the work be done? How: How will he product or service be designed? How will the work be done? How will resources be allocated? Who: Who will do the work?

OPERATIONS MANAGEMENT AND DECISION MAKING Ø Models Ø Ø Quantitative approaches Analysis of tradeoffs OPERATIONS MANAGEMENT AND DECISION MAKING Ø Models Ø Ø Quantitative approaches Analysis of tradeoffs Systems approach Establishing priorities

GENERAL APPROACH TO DECISION MAKING Modeling is a key tool used by all decision GENERAL APPROACH TO DECISION MAKING Modeling is a key tool used by all decision makers – Model - an abstraction of reality; a simplification of something. – Common features of models: Ø They are simplifications of real-life phenomena Ø They omit unimportant details of the real-life systems they mimic so that attention can be focused on the most important aspects of the reallife system 66

MODELS Types of Models: – Physical Models Look like their real-life counterparts – Schematic MODELS Types of Models: – Physical Models Look like their real-life counterparts – Schematic Models Look less like their real-life counterparts than physical models – Mathematical Models Do not look at all like their real-life counterparts

UNDERSTANDING MODELS Keys to successfully using a model in decision making – What is UNDERSTANDING MODELS Keys to successfully using a model in decision making – What is its purpose? – How is it used to generate results? – How are the results interpreted and used? – What are the model’s assumptions and limitations? 68

BENEFITS OF MODELS ØModels are generally easier to use and less expensive than dealing BENEFITS OF MODELS ØModels are generally easier to use and less expensive than dealing with the real system ØRequire users to organize and sometimes quantify information ØProvide a systematic approach to problem solving ØIncrease understanding of the problem ØEnable managers to analyze “What if? ” questions ØEnable managers to specify objectives ØServe as a consistent tool for evaluation and provide a standardized format for analyzing a problem ØEnable users to bring the power of mathematics to bear on a problem.

MODEL LIMITATIONS ØQuantitative information may be emphasized at the expense of qualitative information ØModels MODEL LIMITATIONS ØQuantitative information may be emphasized at the expense of qualitative information ØModels may be incorrectly applied and the results misinterpreted This is a real risk with the widespread availability of sophisticated, computerized models are placed in the hands of uninformed users. ØThe use of models does not guarantee good decisions.

DEGREE OF CUSTOMIZATION § Relative to other standardized products and services customized products: – DEGREE OF CUSTOMIZATION § Relative to other standardized products and services customized products: – Tend to be more labor intensive – Tend to be more time consuming – Tend to require more highly-skilled people – Tend to require more flexible equipment – Have much lower volume of output – Have higher price tags § Degree of customization has a significant influence on the entire organization – Process selection – Job design – Affects marketing, sales, accounting, finance, and information systems 73

ESTABLISHING PRIORITIES ØIn nearly all cases, certain issues or items are more important than ESTABLISHING PRIORITIES ØIn nearly all cases, certain issues or items are more important than others ØRecognizing this allows managers to focus their attention to those efforts that will do the most good ØPareto Phenomenon - a few factors account for a high percentage of occurrence of some event(s) ØThe critical few factors should receive the highest priority Ø 80/20 Rule- 80% of the problems are caused by 20% of the activities ØThis is a concept that is appropriately applied to all 74 areas and levels of management

SYSTEMS APPROACH Ø System - a set of interrelated parts that must work together SYSTEMS APPROACH Ø System - a set of interrelated parts that must work together Ø The business organization is a system composed of subsystems Ø marketing subsystem Ø operations subsystem Ø finance subsystem Ø The systems approach Ø Emphasizes interrelationships among subsystems Ø Main theme is that the whole is greater than the sum of its parts Ø The output and objectives of the organization take precedence over those of any one subsystem 75
