The Luke’s Lobster restaurant in Tenants Harbor, Me.

“It was a steamy summer day in New York in 2009 when Luke Holden, an investment banker, had a craving for a lobster roll,” writes The New York Times (Aug. 25, 2016). Not just any lobster roll, though. He longed for the “fresh off the docks” taste he enjoyed growing up in Maine. Dissatisfied and disappointed in his search, Holden decided to open an authentic Maine lobster shack in Manhattan. To replicate that fresh taste that he remembered, he would need to oversee, track and, where possible, own every step in the process.

Today, he owns 19 Luke’s Lobster restaurants, two food trucks and a lobster tail cart in the U.S., and five shacks in Japan. He holds an ownership stake in a co-op of Maine fishermen, which allows him to track where and how the lobsters are caught, and control the quality, freshness and pricing. He also owns the processing plant that packages and prepares the lobsters for his restaurants.

 This might seem obsessive. But in operations management (see Ch.11 in our text), we call it a vertical integration strategy. Oil companies have long practiced vertical integration to track and control the flow of petroleum from the oil field to the gas pump. Apple controls its flow from chip makers all the way to retail stores.

“Owning one or more levels of the supply chain is a highly effective way to maintain quality and obtain an advantage against competitors,” says an industry expert.

Classroom discussion questions:

  1. Provide other examples of companies that are vertically integrated.
  2. What are the potential disadvantages of vertical integration?

OM in the News: RFID and Luggage Tracking

Radio chips are embedded in the tags being used at Las Vegas' airport ensure that suitcases move more quickly and accurately through the system.
Radio chips are embedded in the tags being used at Las Vegas’ airport ensure that suitcases move more quickly and accurately through the system.

One of my favorite new video cases for this edition is called Alaska Airlines: 20-Minute Baggage Process–Guaranteed! in Chapter 7. This is great example of process analysis and how OM can be applied in a way to improve customer service in the airline industry.  And industry-wide, airlines show a steadily decreasing likelihood of bags going astray. Last year had the lowest rate of wayward luggage — 6.5 bags per 1,000 — in the past 12 years. Why?

Various advances in technology and bag-handling procedures deserve credit, including improvements over the years in the bar-coded tags and optical scanners that have long been in use for identifying and sorting checked luggage. Where bar-coded tags fall short is if the tag is wrinkled, smudged or torn, or not in line of sight of the scanner. If the tag is not readable, the bag can get lost without being noticed. Bar code readers have a “read rate” of only 80%- 95% of baggage tags.

“That is why the industry is intent on improving the tracking rate by looking beyond the 30-year-old baggage bar code,” writes The New York Times (Aug.23, 2016). They are adopting RFID tags that do not need to be seen to be read. Embedded chips can store travel information and need to be only close to radio scanners along the way for the bag’s progress to be recorded. Fliers can use travel apps to keep track of their bags. Delta is spending $50 million on the necessary scanners, printers and radio tags, which look little different from conventional bar-code tags. The system is now in place at all of the 344 airports into which Delta flies.

R.F.I.D. technology is hardly new, of course. But updating to the latest technology requires infrastructure changes that can be expensive and disruptive. And because most airports leave it to each airline to handle its own bag-checking system, the technology and procedures vary widely.

Classroom discussion questions:

  1. What are the advantages of RFID over bar codes?
  2. What does Alaska Air do to make sure bags arrive in 20 minutes?

The default setting will also allow feedback for all parts of homework questions to be accessible to students at all times so they can see at what point their errors occurred.

OM in the News: China’s Factories Turn to Robots

china robotsA Chinese factory near Shanghai is relying on a new breed of workers to maintain its competitive advantage in assembling electronics devices: small robots designed in Germany. China’s appetite for European-made industrial robots is rapidly growing, as rising wages, a shrinking workforce and cultural changes drive more Chinese businesses to automation. The types of robots favored by Chinese manufacturers are also changing, as automation spreads from heavy industries such as auto manufacturing to those that require more precise, flexible robots capable of handling and assembling smaller products, including consumer electronics and apparel.

“At stake is whether China can retain its dominance in manufacturing,” writes The Wall Street Journal (Aug.17, 2016). The rush to buy robots comes in part because China’s population of workers aged 15 to 59 is starting to shrink, forcing manufacturers to turn to automation. The number of the country’s workers peaked in 2010 at more than 900 million and will fall below 800 million by 2050. In addition, the average hourly labor cost of $14.60 in China’s manufacturing heartland has more than doubled as a percentage of U.S. manufacturing wages, from 30% in 2000 to 64% in 2015.

China, in 2013, became the world’s largest market for industrial robots, surpassing all of Western Europe. In 2015, Chinese manufacturers bought roughly 67,000 robots, about a quarter of global sales, and demand is projected to more than double to 150,000 robots annually by 2018. China originally started adopting automation en masse in response to concerns over the quality of goods manufactured in the country. Now, however, Chinese factories—including those that make consumer goods—are buying robots to fill positions that would otherwise sit empty because of high job turnover rates.

Classroom discussion questions:

  1. How does this impact the U.S. drive to regain manufacturing through automation?
  2. How does automation impact the role of OM managers?

 

Guest Post: Future Research Themes in Supply Chain Management

andreas wielandToday’s Guest Post comes from Andreas Wieland, Assistant Professor of Supply Chain Management at Copenhagen Business School. This is his 4th posting.

What are the future dominant research themes in supply chain management? With my coathors Robert Handfield and Christian Durach, our new article, “Mapping the Landscape of Future Research Themes in Supply Chain Management” (see Journal of Business Logistics, Aug., 2016), answers the question. The results are based on survey data collected from 141 leading academics from the SCM discipline.

The respondents were presented a list with 35 topics that are potentially important in SCM. They were then asked to assess to what level they believe these topics will become important in the next years and to what level they think these topics should become important. The will– and should-become-important top 10 lists do not differ substantially. Both of them include the following topics: sustainability & green issues, analytics, risk management & disruption, health care, and innovation. Interestingly, big data, the topic ranked 1st on the will-become-important top 10 list, does not appear on the should-become-important top 10 list. Instead, the people dimension of SCM appears in the should-become-important top 10 list.

We also calculated the differences between the will- and should-become-important survey data. We find that the people dimension of SCM, ethical issues, internal integration, transparency/visibility, and human capital/talent management are the five topics that are expected to be most under researched in the next couple of years. So, if you are planning to start a new research project or a Ph.D. related to SCM, these topics could be good choices. On the other end, big data and analytics turn out to be the topics that are expected to be most over researched.

We also linked the topics that top the should-become-important list to each other. This has led to a table containing ideas that could lead to innovative and cross-disciplinary research questions.

OM in the News: It’s Getting More Expensive to Make Cars in Mexico

mexico 2mexico 1When car companies began flocking to Mexico more than two decades ago, the big lure was labor, which was plentiful and inexpensive. “Today,” writes The Wall Street Journal (Aug.15, 2016), “with an auto-production boom in high gear, those advantages are being chipped away.” Toyota, BMW, Ford, and several other auto makers have committed to spend a combined $15.8 billion to build new assembly plants or expand existing factories. That is on top of the more than a dozen plants already in operation and billions more being spent by auto-parts suppliers to keep pace.

The competition for employees—both finding and retaining them—is nudging up labor costs. The going rate ranges from under $1 an hour at some parts factories to nearly $3 an hour at the large assembly facilities. That is well above Mexico’s minimum wage of 73 pesos, or $4 a day. Still, it is too low to attract the quantity and quality of workers needed to fill the surging number of openings. Retention and retraining programs are becoming the norm as are bonuses for employees who agree to stay in place, especially those with valued skills. Some factories are luring recruits with perks such as a new cowboy boots. Vacancies are becoming the norm.

Auto-industry investment in the country accelerated in the 1990s after the signing of Nafta. In the lead were Detroit car makers and parts suppliers looking to avoid high labor costs at their unionized plants in the U.S.

Classroom discussion questions:

1.Why did so many auto manufacturers select Mexico?

2. What can OM managers do to retain employees?

 

 

OM in the News: Amazon’s New Delivery Strategy

An Amazon Prime Air drone.
An Amazon Prime Air drone.

“Over the last few years, Amazon has left a trail of clues suggesting that it is radically altering how it delivers goods,” writes The New York Times (Aug.11, 2016). Among other moves, it has set up its own fleet of trucks; introduced an Uber-like crowd sourced delivery service; built many robot-powered warehouses; and continued to invest in a plan to use drones for delivery. It made another splash last week, when it showed off an Amazon-branded Boeing 767 airplane, one of more than 40 in its planned fleet.

These moves have fueled speculation that Amazon is trying to replace the 3rd-party shipping companies it now relies on — including UPS, FedEx and the U.S.P.S. — with its homegrown delivery service. Its logistics investments have also fed the theory that Amazon has become essentially unbeatable in American e-commerce.

The company, it appears, has a 2-tiered vision for the future of shipping. First, it’s not trying to replace 3rd-party shippers. Instead, Amazon wants to add as much capacity to its operations as possible, and rather than replace partners like UPS and FedEx, it is spending heavily on delivery services to add to its overall capacity and efficiency. Amazon’s longer-term goal is more potentially transformative. It wants to escape the vicissitudes of roads and humans, going fully autonomous in the sky. The company’s drone program could be combined with warehouses manned by robots and trucks that drive themselves to unlock a new autonomous future for Amazon.

If Amazon’s drone program succeeds (and Amazon says it is well on track), it could fundamentally alter the company’s cost structure. A decade from now, drones would reduce the unit cost of each Amazon delivery by about half.  According to Amazon, we will see drones in action within 5 years.

Classroom discussion questions:

1. Why does Amazon wish to enhance its shipping strategy?

2. What are the advantages and disadvantages of the drone program?

OM in the News: The Productivity Challenge

productivityWhat better way to start the fall semester but with a discussion of the importance of productivity (see Chapter 1, pages 13-18). There we write: “only through increases in productivity can the standard of living improve.” For well over a century, the U.S. has been able to increase productivity at about 2.5% per year, meaning U.S. wealth doubled every 30 years. But in the past decade, the news is not good. As The Wall Street Journal’s (Aug. 10, 2016) front page headline declares: “Productivity Fall Imperils Growth.”

This longest slide in worker productivity since the late 1970s is haunting the U.S. economy’s long-term prospects. Productivity in the 2nd quarter was down 0.4% from a year earlier, the first annual decline in 3 years. That was a further step down from already tepid average annual productivity growth of 1.3% in 2007 through 2015, itself just half the pace seen in 2000 through 2007, and the trend shows little sign of reversing. Productivity has slowed dramatically since the information technology-fueled boom of the late 1990s, when strong productivity gains translated into robust growth for household incomes and the overall economy.

Adds Fed Chair Janet Yellen: “the outlook for productivity growth is a key uncertainty for the U.S. economy and a very difficult question that has divided the economics profession. Some are relatively optimistic, pointing to the continuing pace of innovations that promise revolutionary technologies, from genetically tailored medical therapies to self-driving cars. Others believe that the low-hanging fruit of innovation largely has been picked and that there is simply less scope for further gains.”

Throughout our text we examine how to improve productivity through operations management.

Classroom discussion questions:

  1. Why is productivity important to OM managers?
  2. What can be done to raise productivity levels in a company? In a country?

OM in the News: Airlines Still Mastering the Role of Technology

A Delta employee hands out snacks to passengers waiting to check in at Newark airport this week

Just as we have seen rapid advances in technology in the manufacturing sector (see Ch. 7), so do we see the critical role of technology in services. This week, for example, a power outage at Delta Air Lines grounded thousands of passengers, wreaking havoc on the carrier’s reservations system and drawing attention to antiquated technology that has plagued many airlines. The outage canceled hundreds of flights and snarled Delta’s efforts to alert passengers to the problems via its apps and on airline flight-information displays.

When departing flights can’t take off, tie-ups at hub airports follow because gates aren’t available for arriving flights. Further delays arise because planes and crews are out of position to follow the published schedule. It can take days for a carrier to recover and get all of its passengers to their destinations.

The technical problems will cost Delta millions of dollars in lost revenue and damage its hard-won reputation for reliability, reports The Wall Street Journal (Aug. 9, 2016).  The meltdown highlights the vulnerability in Delta’s computer system, and raises questions about whether a recent wave of U.S. airline mergers that created 4 large carriers controlling 85% of domestic capacity has built companies too reliant on IT systems that date from the 1990s. Delta merged with Northwest Airlines 8 years ago.

These IT systems—which run everything from flight dispatching to crew scheduling, passenger check-in, airport-departure information displays, ticket sales and frequent-flier programs—gradually have been updated but are still vulnerable. Following the loss of power, some critical systems and network equipment didn’t switch over to Delta’s backup systems. Delta aimed to limit customer backlash, but customers unleashed their frustration with 43,000 social media complaints.

Classroom discussion questions:
1. What did Delta do wrong IT-wise?

2. Why is a technology error more damaging in an airline than in a restaurant or university?

Teaching Tip: Staying Balanced as You Prepare for the Fall Semester

burnoutI just read an interesting piece that is slightly outside our usual OM blog themes–but very worthwhile nonetheless. “It may be time,” writes Faculty Focus, “to identify some new strategies for self-care.” Here is a menu of ideas to help faculty design a balanced and productive work life:

  1. Examine how you spend your time and energy: Which work-related tasks leave you feeling energized or excited? Which feel like unnecessary chores? Next year, prioritize activities that build you up or represent an important contribution to the field. Cultivate the art of saying “no.”
  2. Rethink OM course design: Use creative course design strategies and tools to provide engaging experiences for students without taking up a disproportionate amount of your time. For example, use a simple audio recording tool to provide feedback instead of typing your comments. Vocaroo and VoiceThread make great options. Students appreciate the personal approach, and providing verbal feedback takes far less time than generating written comments.
  3. Refine your daily workflow: Consider using a service that delivers e-mails a few times per day rather than trying to work through the persistent interruptions of new emails arriving in your inbox. Use an electronic “to do” list like Todoist or Wunderlist to organize reminders and deadlines. Use Google or Outlook calendar scheduling for reminders to take a daily walk, meditation, or a quick stretch.
  4. Evaluate your food and fuel: Food can drag you down or prop you up. Step away from your desk periodically for a snack, and be sure to choose one that is nourishing as well as invigorating.  Use your snack break to get outdoors or connect with your colleagues while you nourish yourself.

Self-care isn’t an all-or-nothing approach. Starting small is ideal. Pick one or two practices to implement tomorrow.

OM in the News: A New View of TQM in Hospitals

The atrium of the Henry Ford West Bloomfield Hospital
The atrium of the Henry Ford West Bloomfield Hospital

At the Henry Ford West Bloomfield Hospital outside Detroit, patients arrive to uniformed valets and professional greeters. Wi-Fi is free and patient meals are served on demand 24 hours a day. Members of the spa staff give in-room massages and other treatments.

While clinical care is the focus of any medical center, hospitals have many incentives to move toward hotel-inspired features, services and staff training. And competing on the amenities is all the more important because there is so little reliable comparative data on hospitals’ medical outcomes. “In the absence of hard data on cancer treatment or surgery success, patients may look to the quality of the hospital’s environment,” writes The New York Times (Aug.2, 2016).

In 2009, a 24-hour room service at Henry Ford West Bloomfield was introduced instead of set meal schedules. Similarly, patients at the more than 50 Henry Ford Medical outpatient centers in the region can choose the time and location of many tests, procedures and appointments using an online system modeled on airline reservation portals. When it was introduced in 2014, cancellation and no-show rates dropped immediately.

At Henry Ford West Bloomfield, scores from federally mandated surveys show that the evolving features at the hospital have helped to improve its customer satisfaction ratings and make patients more likely to recommend the hospital to others. Length of stay and readmission rates have also decreased, which allows more beds to open up and the hospital to treat more patients. Indeed, a study by Deloitte found that hospitals with higher patient experience ratings were generally more profitable than those with lower scores. “Hospitals want to create a loyal customer base,” says an industry expert.

Classroom discussion questions:

  1. Referring to the Global Company Profile featuring Arnold Palmer Hospital (see Ch. 6), what techniques does Arnold Palmer use that are not noted in the Henry Ford article?
  2. Why is it hard to measure hospital quality?

MyOMLab: Some Exciting New Resources for Fall 2016

There have been many enhancement to MyOMlab that we will share with you in the coming days. Here are just two that we are very excited about. If you have not tried out MyOMLab as a learning and assessment tool, let your Pearson rep (or me) know and we will set up a private tutorial for you. More than half of our adopters are using this fantastic package already.

Dynamic Study Modules help students study effectively on their own by continuously assessing their activity and performance in real time.

  1. Instructors now have the ability to remove questions from a module to add additional personalization.
  2. Changes are now retained when copying a course for future semesters.

OM Simulations
Interactive and robust, these simulations were designed for our Operations Management students to provide hands-on experiences in real-world roles, helping them to link course concepts to on-the-job application.  Using real-life myomlab simulationsituations, students evaluate information and then engage in decision-making and critical analysis.

  • Four new simulations are available this month as part of MyOMLab: Inventory Management (Chapter 12), Quality Management (Chapter 6), Forecasting (Chapter 4), and Project Management (Chapter 3).
    • 90% of students who piloted the simulations in 2016 would recommend their instructors use them in the course.
