WHAT IS VALUE ADDED?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.

Jobs in services are often less structured than in manufacturing Customer contact is generally much higher in services compared

to manufacturing In many services, worker skill levels are low compared to those of

manufacturing employees Services are adding many new workers in low-skill, entry-level

positions Employee turnover is high in services, especially in low-skill jobs Input variability tends to be higher in many service environments

than in manufacturing Service performance can be adversely affected by many factors

outside of the manager’s control (e.g., employee and customer attitudes)

PROCESS MANAGEMENTPROCESS MANAGEMENTProcess - one or more actions that transform inputs into outputs

Three Categories of Business ProcessesThree Categories of Business Processes::

Upper-management processes

These govern the operation of the entire organization.

Operational processes

These are core processes that make up the value stream.

Supporting processes

These support the core processes.

PROCESS VARIATIONPROCESS VARIATIONFour 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 variation 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.

The operations function includes many interrelated activities such as:

– Forecasting– Capacity planning– Scheduling– Managing inventories– Assuring quality– Motivating employees– Deciding where to locate facilities– And more . . .

SCOPE OF OPERATIONS SCOPE OF OPERATIONS MANAGEMENTMANAGEMENT

The scope of operations management ranges across the organization.

Page 39: INTRODUCTION TO OPERATIONS MANAGEMENT.   What is operations? The part of a business organization that is responsible for producing goods or services

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.

THE DECLINE IN THE DECLINE IN MANUFACTURING MANUFACTURING

EMPLOYMENTEMPLOYMENTProductivity

– Increasing productivity allows companies to maintain or increase their output using fewer workers

Outsourcing– Some manufacturing work has been outsourced to

more productive companiesA Statistical Artifact

– Manufacturers are increasingly using contract and temporary labor which no longer show up in the statistics as manufacturing employment

Page 44: INTRODUCTION TO OPERATIONS MANAGEMENT.   What is operations? The part of a business organization that is responsible for producing goods or services

Most operations decisions involve many alternatives that can have quite different impacts on costs or profitsTypical operations decisions include: What: 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?

GENERAL APPROACH TO GENERAL APPROACH TO DECISION MAKINGDECISION MAKING

Modeling is a key tool used by all decision makers– Model - an abstraction of reality; a

simplification of something.– Common features of models:

They are simplifications of real-life phenomena

They omit unimportant details of the real-life systems they mimic so that attention can be focused on the most important aspects of the real-life system

Page 47: INTRODUCTION TO OPERATIONS MANAGEMENT.   What is operations? The part of a business organization that is responsible for producing goods or services

MODELSMODELS

Types of Models:– Physical Models

Look like their real-life counterparts– Schematic Models

Look less like their real-life counterparts than physical models

– Mathematical ModelsDo not look at all like their real-life

counterparts

Page 48: INTRODUCTION TO OPERATIONS MANAGEMENT.   What is operations? The part of a business organization that is responsible for producing goods or services

4848

UNDERSTANDING UNDERSTANDING MODELSMODELS

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?

Page 49: INTRODUCTION TO OPERATIONS MANAGEMENT.   What is operations? The part of a business organization that is responsible for producing goods or services

BENEFITS OF MODELSBENEFITS OF MODELSModels are generally easier to use and less expensive than

dealing with the real systemRequire users to organize and sometimes quantify informationProvide a systematic approach to problem solvingIncrease understanding of the problemEnable managers to analyze “What if?” questionsEnable managers to specify objectives Serve as a consistent tool for evaluation and provide a

standardized format for analyzing a problemEnable users to bring the power of mathematics to bear on a

problem.

Page 50: INTRODUCTION TO OPERATIONS MANAGEMENT.   What is operations? The part of a business organization that is responsible for producing goods or services

MODEL LIMITATIONSMODEL LIMITATIONS

Quantitative information may be emphasized at the expense of qualitative information

Models 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.

The use of models does not guarantee good decisions.

METRICS AND TRADE-OFFSMETRICS AND TRADE-OFFS

Performance Metrics– All managers use

metrics to manage and control operations Profits Costs Productivity Forecast accuracy

Analysis of Trade-Offs– A trade-off is giving

up one thing in return for something else Carrying more

inventory (an expense) in order to achieve a greater level of customer service

Tradeoffs

ESTABLISHING PRIORITIESESTABLISHING PRIORITIES

In nearly all cases, certain issues or items are more important than others

Recognizing this allows managers to focus their attention to those efforts that will do the most good

ESTABLISHING PRIORITIES: ESTABLISHING PRIORITIES: PARETO PHENOMENONPARETO PHENOMENON

How do we identify the vital few?

Pareto Phenomenon - a few factors account for a high percentage of occurrence of some event(s)

The critical few factors should receive the highest priority80/20 Rule- 80% of the problems are caused by 20% of the activities This is a concept that is appropriately applied to all areas and levels of management

SYSTEMS APPROACHSYSTEMS APPROACHSystem - a set of interrelated parts that must work together

The business organization is a system composed of subsystemsmarketing subsystemoperations subsystemfinance subsystem

The systems approach Emphasizes interrelationships among subsystemsMain theme is that the whole is greater than the sum of

its partsThe output and objectives of the organization take

precedence over those of any one subsystem

Relative to other standardized products and services customized products:

Tend to be more labor intensiveTend to be more time consumingTend to require more highly-skilled peopleTend to require more flexible equipmentHave much lower volume of outputHave higher price tags

Movement was led by efficiency engineer, Frederick Winslow Taylor– Believed in a “ Science of Management”

based on observation, measurement, analysis and improvement of work methods, and economic incentives

– Management is responsible for planning, carefully selecting and training workers, finding the best way to perform each job, achieving cooperate between management and workers, and separating management activities from work activities
