Operations Management

Operations Management
Chapter 1 – Operations and Productivity PowerPoint presentation to accompany Heizer/Render, Operations Management, 11th Ed. Some additions and deletions have been made by Ömer Yağız to this slide set (Revised March 2015)

Some real life scenarios which I used in the past to highlight the importance of Operations Management fortunately, some of these scenarios are no more valid many improvements have been realized both in the public and private sector improvement, or continuous improvement, to be exact, is the right approach to increasing quality, efficiency, productivity, and profitability.

Some Real Life Scenarios in OM
Many of us have witnessed the agony and the suffering (and even deaths) that many senior citizens have had to endure in order to collect their retirement or pension pay from the various commercial banks. This was an episode that repeated every month or every three months, especially in large urban centers. The government organizations and the banks involved in this service process unfortunately did nothing for a long time to improve the situation and increase the quality of this rather routine service (now the situation is a little better)

SOME REAL-LIFE SCENARIOS IN OM
You mail a letter by Express Post (APS) to an address in İstanbul. The recipient gets it after 3 days; whereas a package sent to İstanbul via Yurtiçi Kargo (or any of the others) is in the hands of the addressee in 6 hours. Plus, order tracking on Google Earth! QUALITY OF SERVICE? You buy a shirt from an expensive store and pay lots of money; the buttons come off after the shirt is worn three times. The manufacturer has to really make a special(!) effort to achieve this terrible quality.

A THY plane takes off 40 minutes late from an airport because some Japanese tourists on board forget to identify their baggage before boarding the plane. The plane flies from İstanbul to Ankara in 50 minutes. 40 minutes delay for a 50 minute flight !! HOW DO WE EXPLAIN THIS IN TERMS OF EFFICIENCY, PRODUCTIVITY, AND PROFITABILITY ? (This has been rectified some time ago by the elimination of baggage identification prior to boarding.)

A real episode at Esenboğa on Feb. 6, 2012
Esenboğa Airport lots of delays and cancellations due to snow and winter conditions an operations manager’s nightmare (kâbus) unhappy and angry passengers THY and TGS service personnel in a very difficult (and unenviable) position

A real episode at Esenboğa on Feb. 6, 2012
This serious situation had a very happy ending for the passengers and service personnel. HOW? full and timely information given to passengers face-to-face and via electronic boards effective and timely catering service to passengers at the gates very courteous, understanding and helpful attitude by the ground service personnel towards the passengers nobody had the courage to complain and/or say something bad about the situation, including myself..

Why did some people prefer McDonald’s or similar fast-food restaurants despite the fact that it they were more expensive than comparable food served elsewhere? The same is true for Varan and Ulusoy bus companies.. When you go to some government office (say, the Tax Bureau) you spend so much you feel terribly exhausted after a very routine task. Is the whole process designed to maximize pain to citizens ? Now, things are a bit different; next slide…

Things are better at the Tax Bureau attitude change on the part of personnel (civil servant concept) technology in general, IT in particular, makes the whole process easier, less time- consuming, more efficient, and less costly errors are minimized personnel assist those in need of help for filling out forms, etc. they even offer you free tea at the Hitit Vergi Dairesi..

Things are also better at Çankaya Kaymakamlığı.. Apostille service unit 1.5 TL per apostille charged 2 X 1.5 TL = 3.00 TL a 3-ply receipt costs 3.00 TL no charge for 2 or less apostilles; 3 or more apostilles charged at the rate of 1.50 TL per apostille amazingly clever practice by a public organization!! Olamaz, rüya mı bu?

During registration periods at many universities, poor students have to report to so many different offices and people, and have to wait so long in several lines. Not only the students but also instructors and administrators have to go through the same unpleasant experience. Indeed, we are a society of endless waiting lines! IS THIS SOMETHING ORDAINED BY GOD OR WHAT ?? (Now with online registration, the situation has improved somewhat)

What Is Operations Management?
Production is the creation of goods and services Operations management (OM) is the set of activities that creates value in the form of goods and services by transforming inputs into outputs

OM Involves Managing Transformations
Process (Value Adding) Input Output People Plants Parts Processes Planning and Control Transformation is enabled by The 5 Ps of OM:

Transformations Physical and chemical--manufacturing (shoes, PC’s, planes, paint, detergents) Locational--transportation (rail, sea, air, road) Exchange--retailing (all kinds of stores, offices), banking ?? Storage--warehousing (normal and cold storage) Physiological--health care (hospitals, clinics) Informational--telecommunications (schools, Reuter Services, Internet and blogs, news media, TV services, METU)

Operations as the Technical Core
Finance Capital Markets, Stockholders Marketing Customers Workers Suppliers Purchasing Personnel

Organizing to Produce Goods and Services
Essential functions: Marketing – generates demand Production/operations – creates the product Finance/accounting – tracks how well the organization is doing, pays bills, collects the money

The Supply Chain A global network of organizations and activities that supply a firm with goods and services Members of the supply chain collaborate to achieve high levels of customer satisfaction, efficiency and competitive advantage.

Why Study OM? OM is one of three major functions (marketing, finance, and operations) of any organization We want (and need) to know how goods and services are produced We want to understand what operations managers do OM is such a costly part of an organization

The Strategic Decisions
Design of goods and services Defines what is required of operations Product design determines quality, sustainability and human resources Managing quality Determine the customer’s quality expectations Establish policies and procedures to identify and achieve that quality Table 1.2 (cont.)

Process and capacity design How is a good or service produced? Commits management to specific technology, quality, resources, and investment. Location strategy Nearness to customers, suppliers, and talent. Considering costs, infrastructure, logistics, and government . Table 1.2 (cont.)

Layout strategy How should we arrange the facility? Integrate capacity needs, personnel levels, technology, and inventory Human resources and job design Recruit, motivate, and retain personnel with the required talent and skills. Integral and expensive part of the total system design. Using this and subsequent slides, you might go through in more detail the decisions of Operations Management. While greater detail is provided by these slides than the earlier one, you may still decide to have the students contribute examples from their own experience. Table 1.2 (cont.)

Supply chain management Integrate supply chain into the firm’s strategy Determine what is to be purchased, from whom, and under what conditions. Inventory managementI Inventory ordering and holding decisions. Optimize considering customer satisfaction, supplier capability, and production schedules. Table 1.2 (cont.)

Scheduling Determine and implement intermediate- and short-term schedules. Utilize personnel and facilities while meeting customer demands. Maintenance Consider facility capacity, production demands, and personnel. Maintain a reliable and stable process. Table 1.2 (cont.)

Industrial engineering Management science (operations research) Biological science Physical sciences Information technology

What is Industrial Engineering ?
Industrial engineering is concerned with the design, installation, and improvement of integrated systems of people, material, information, equipment and energy. It draws upon specialized knowledge and skills in the mathematical, physical and social sciences, together with the principles and methods of engineering analysis and design to specify, predict and evaluate the results to be obtained from such systems. IIE Web Site --

What is Operations Research ?
OR/MS Professionals aim to provide rational bases for decision making by seeking to understand and structure complex situations and to use this understanding to predict system behavior and improve system performance. Much of this work is done using analytical and numerical techniques to develop and manipulate mathematical and computer models of organizational systems composed of people, machines, and procedures

What is Operations Research ?
OR/MS draws upon ideas from engineering, management, mathematics, and psychology to contribute to a wide variety of application domains; the field is closely related to several other fields in the "decision sciences" -- applied mathematics, computer science, economics, and industrial engineering. INFORMS Web Site --

New Challenges in OM From To Local or national focus Global focus

Current Issues Speeding up the time it takes to get new products into production. (Concurrent engineering -- eş zamanlı mühendislik) Developing flexible production systems to enable “mass customization” of products and services. (kişiye özel seri üretim; kitlesel bireyselleştirme; özelleştirme) Managing global production networks. Developing and integrating new production technologies into existing production systems ….

Current Issues Achieving high quality quickly and keeping it up in the face of restructuring. Managing a diverse workforce. Conforming to environmental constraints, ethical standards, and government regulations.

Mass Customization (kişiye özel seri üretim) Interesting Example
Panasonic Bicycles Matsushita Corp.- NBIC 21 employeees plus CAD system 18 basic models in 199 color patterns; 8 million variations Standard model - 90 min/unit; special model min/unit Price: %20-30 more than standard model Delivery time: ~ 3 weeks (Why? -- feeling of anticipation for something special!!)

Characteristics of Goods
Tangible product Consistent product definition Production usually separate from consumption Can be inventoried Low customer interaction Often easy to automate

Characteristics of Service
Intangible product Produced and consumed at same time Often unique High customer interaction Inconsistent product definition Often knowledge-based(education, medical, legal, etc.) Frequently dispersed(local office, house call, etc.) Not possible or easy to automate

Goods Versus Services Can be resold Can be inventoried
Some aspects of quality measurable Selling is distinct from production Product is transportable Site of facility important for cost Often easy to automate Revenue generated primarily from tangible product Attributes of Goods (Tangible Product) Attributes of Services (Intangible Product) Reselling unusual Difficult to inventory Quality difficult to measure Selling is part of service Provider, not product, is often transportable Site of facility important for customer contact Often difficult to automate Revenue generated primarily from the intangible service Table 1.3

Differences Between Goods and Services
TABLE 1.3 CHARACTERISTICS OF SERVICES CHARACTERISTICS OF GOODS Intangible: Ride in an airline seat Tangible: The seat itself Produced and consumed simultaneously: Beauty salon produces a haircut that is consumed as it is produced Product can usually be kept in inventory (beauty care products) Unique: Your investments and medical care are unique Similar products produced (iPods) High customer interaction: Often what the customer is paying for (consulting, education) Limited customer involvement in production Inconsistent product definition: Auto Insurance changes with age and type of car Product standardized (iPhone) Often knowledge based: Legal, education, and medical services are hard to automate Standard tangible product tends to make automation feasible Services dispersed: Service may occur at retail store, local office, house call, or via internet. Product typically produced at a fixed facility Quality may be hard to evaluate: Consulting, education, and medical services Many aspects of quality for tangible products are easy to evaluate (strength of a bolt) Reselling is unusual: Musical concert or medical care Product often has some residual value

New Trends in OM Past Causes Future Local or national focus
Reliable worldwide communication and transportation networks Global focus, moving production offshore Batch (large) shipments Short product life cycles and cost of capital put pressure on reducing inventory Just-in-time performance Low-bid purchasing Supply chain competition requires that suppliers be engaged in a focus on the end customer Supply chain partners, collaboration, alliances, outsourcing Figure 1.6

New Trends in OM Past Causes Future Lengthy product development
Shorter life cycles, Internet, rapid international communication, computer-aided design, and international collaboration Rapid product development, alliances, collaborative designs Standardized products Affluence and worldwide markets; increasingly flexible production processes Mass customization with added emphasis on quality Job specialization Changing socioculture milieu; increasingly a knowledge and information society Empowered employees, teams, and lean production Figure 1.6

New Trends in OM Past Causes Future Low-cost focus
Environmental issues, ISO 14000, increasing disposal costs Environmentally sensitive production, green manufacturing, recycled materials, remanufacturing Ethics not at forefront Businesses operate more openly; public and global review of ethics; opposition to child labor, bribery, pollution High ethical standards and social responsibility expected Figure 1.6

Global focus Just-in-time performance Supply chain partnering Rapid product development Mass customization Empowered employees Environmentally sensitive production Ethics

Productivity Challenge
Productivity is the ratio of outputs (goods and services) divided by the inputs (resources such as labor and capital) The objective is to improve productivity! Important Note! Production is a measure of output only and not a measure of efficiency

Labor, capital, management
The Economic System Inputs Labor, capital, management Processes The U.S. economic system transforms inputs to outputs at about an annual 2.5% increase in productivity per year. The productivity increase is the result of a mix of capital (38% of 2.5%), labor (10% of 2.5%), and management (52% of 2.5%). Outputs Goods and services Feedback loop Figure 1.7

Improving Productivity at Starbucks
A team of 10 analysts continually look for ways to shave time. Some improvements: Stop requiring signatures on credit card purchases under $25 Saved 8 seconds per transaction Change the size of the ice scoop Saved 14 seconds per drink New espresso machines Saved 12 seconds per shot

Improving Productivity at Starbucks
A team of 10 analysts continually look for ways to shave time. Some improvements: Operations improvements have helped Starbucks increase yearly revenue per outlet by $200,000 to $940,000 in six years. Productivity has improved by 27%, or about 4.5% per year. Stop requiring signatures on credit card purchases under $25 Saved 8 seconds per transaction Change the size of the ice scoop Saved 14 seconds per drink New espresso machines Saved 12 seconds per shot

Efficiency vs. effectiveness
Efficiency – doing a job with a minimum of resources and waste i.e. doing the job well. Efficiency= actual output/standard output (70pcs/hr) / (60 pcs/hr) = 1.17 Effectiveness – achieving your stated goal or purpose i.e. doing the right job.

Productivity Units produced Input used Productivity =
Measure of process improvement Represents output relative to input Only through productivity increases can our standard of living improve

Productivity Calculations
Labor Productivity Productivity = Units produced Labor-hours used = = 4 units/labor-hour 1,000 250 One resource input  single-factor productivity

Multi-Factor Productivity
Output Labor + Material + Energy + Capital + Miscellaneous Productivity = Also known as total factor productivity Output and inputs are often expressed in dollars Multiple resource inputs  multi-factor productivity

Illustration- Collins Title Productivity
Staff of 4 works 8 hrs/day 8 titles/day Payroll cost = $640/day Overhead = $400/day Old System (Non-computerized): 8 titles/day 32 labor-hrs = Old labor productivity Note: Collins Title is a reinsurance company (tapu sigortası). It has set up a new computerized title search system.

Measurement Problems Quality may change while the quantity of inputs and outputs remains constant External elements may cause an increase or decrease in productivity(power or gas shortages, strikes & lockouts, etc) Precise units of measure may be lacking (not all cars may require the same inputs– Opel Corsa vs. Porsche)

Productivity Variables
For the U.S. economy’s 2.5 % annual increase Labor - contributes about 10% of the annual increase Capital - contributes about 38% of the annual increase Management - contributes about 52% of the annual increase

Key Variables for Improved Labor Productivity
Basic education appropriate for the labor force Diet of the labor force Social overhead that makes labor available (transportation, sanitation, health services, etc.) Maintaining and enhancing skills in the midst of rapidly changing technology and knowledge

Labor Skills About half of the 17-year-olds in the US cannot correctly answer questions of this type Figure 1.8

Investment and Productivity
10 8 6 4 2 Percent increase in productivity Percentage investment

Service Productivity Typically labor intensive
Frequently focused on unique individual attributes or desires Often an intellectual task performed by professionals Often difficult to mechanize Often difficult to evaluate for quality
