Supply Chain Sourcing Game: A Negotiation Exercise

This article introduces an exercise that simulates the negotiation process in a dynamic supply chain. The retailer and wholesaler roles are assigned to student groups who negotiate supply contracts in a number of rounds during a class period. Each group makes pricing, inventory, and ordering decision concurrently, and competes with others to achieve the highest profit. The exercise is easy to implement using pen and paper, and lends itself to a wide variety of negotiation environments.     

Teaching Teachers about Supply Chain Management to Influence Students’ Career and Education Choices

Since teachers are influential in high school students’ career choices, enabling high school teachers to introduce educational and career opportunities in supply chain management is a viable strategy for reaching high school students about these opportunities. This article presents a pilot program of supply chain workshops to educate high school and middle school teachers and guidance counselors about the opportunities in supply chain management and logistics and to enable them to integrate supply chain concepts into their teaching. These workshops incorporate a mix of slideshows to introduce concepts, hands‐on activities to illustrate how the concepts work, and field trips and guest speakers to demonstrate concepts in real world applications.     

Developing Students’ Understanding of Co‐opetition and Multilevel Inventory Management Strategies in Supply Chains: An In‐Class Spreadsheet Simulation Exercise

Instructors look for ways to explain to students how supply chains can be constructed so that competing suppliers can work together to improve inventory management performance (i.e., a phenomenon known as co‐opetition). An Excel spreadsheet‐driven simulation is presented that models a complete multilevel supply chain system—customer, retailer, wholesaler, distributor, and manufacturer—for up to six competing products. Students are provided the opportunity to compare the inventory cost and other key performance metrics of the alternative multilevel supply chain structures. This article explains the simulation model, describes the instructional approach, and presents assessment results from students in an introductory operations management course. Students find that the simulation is easy to use and helps them understand the performance impact of strategic supplier collaborations on supply chain operating performance.     

Appreciating the Complexity of Project Management Execution: Using Simulation in the Classroom

As the popularity and importance of project management increase, so does the need for well‐prepared project managers. This article discusses our experiences using a project management simulation in undergraduate and MBA classes to help students better grasp the complexity of project management. This approach gives students hands‐on experience with many facets in the project management life cycle and provides them with feedback on their performance as project managers. This article provides an overview of the simulation exercises, guidance for classroom integration, and evidence of effectiveness.     

Teaching Supply Chain Management Complexities: A SCOR Model Based Classroom Simulation

The SCOR (Supply Chain Operations Reference) Model Supply Chain Classroom Simulation is an in‐class experiential learning activity that helps students develop a holistic understanding of the processes and challenges of supply chain management. The simulation has broader learning objectives than other supply chain related activities such as the Beer Game. Competing supply chains work to produce and sell two products, each experiencing differential demand. Seasonal demand, time delays, quality defects, and disruptions offer complexities that are part of actual supply chain management. The behavioral dynamics of collaboration between various functional nodes is illustrated through students’ interactions as they try to achieve their role's objectives. Through their decisions and actions, students develop a practical understanding of the processes and complexities of supply chain management. The classroom simulation actively engages students, and has been used successfully in multiple courses at the undergraduate and graduate levels at multiple universities and by a major corporation during a manager training session. Assessments indicate that the simulation is an effective experiential learning activity. While it offers learning outcome flexibility, common debrief themes are SCOR model processes, supply chain relationships, information flow, seasonal demand, quality defects, reverse logistics, and supply chain disruptions.     

Newsvendor Game: A Behavioral Exercise in Decision Making under Risk

The newsvendor problem is a classic problem of decision making under risk that is taught in traditional Operations and Supply Chain Management classes as a single‐period inventory problem. We discuss the following three pedagogical points of interest to any instructor tasked with teaching this topic: a) why the newsvendor model is relevant in this day and age; b) how to make better sense of the newsvendor problem for students; and c) how to easily implement and administer an active learning exercise in either a traditional classroom, or an online setting. This active learning exercise is a quick, effective, and meaningful way of demonstrating a variety of concepts related to the newsvendor problem that include: a) the rational economic method of calculating optimal order quantity, b) the inherent risk in forecasting and ordering decisions as they relate to surpluses and shortages; and c) the cognitive limitations in decision making that often result in irrational but predictable decision‐making behavior as demonstrated by empirical research on newsvendor behavior. This exercise can help instructors and students transition into broader discussions on human behavior, cognitive limitations, and perceptions of risk. Overall, it should provide the student with an improved understanding of the operational and behavioral issues associated with decision making under risk.     

Forecasting: Exercises to Enhance Learning from Business Simulations

Forecasting the outputs of dynamic systems develops a richer understanding of relevant inputs and their interrelationships than merely observing them ex post. Academic business simulations foster students’ development of this critical competency, but learning outcomes can be significantly augmented with relatively simple, complementary exercises in forecasting. We introduce an in‐class forecasting exercise that is easily added to simulations or in any course where students gain from untangling the determinants of quantitative outcomes. The exercise also enhances opportunities for team‐building and spirited competition. Implementation details, evidence of effectiveness, and implications are discussed.     

A Simulation for Managing Complexity in Sales and Operations Planning Decisions

Within the classroom it is often difficult to convey the complexities and intricacies that go into making sales and operations planning decisions. This article describes an in‐class simulation that allows students to gain hands‐on experience with the complexities in making forecasting, inventory, and supplier selection decisions as part of the sales and operations planning process. The activity may be run during one class period and is flexible enough to accommodate almost any class size. During the simulation, students may apply forecasting techniques, inventory management concepts, and supplier selection processes, while experiencing the effects of supply chain disruptions. This simulation is recommended to be used after forecasting, inventory management, and supplier selection topics have been discussed. An overview of the exercise and evidence of its effectiveness is provided.     

Teaching Plan‐Do‐Study‐Act (PDSA) in a Supply Chain Context: A Paper Football In‐Class Activity

We develop a single‐class period learning game for the Plan‐Do‐Study‐Act (PDSA) improvement cycle. The experiential activity walks teams through the PDSA problem‐solving process as they create paper American footballs and improve their performance using each step of the cycle. The game is one of the first to focus on PDSA. Key benefits include increased student attention, engagement, and learning. Empirical tests show that participant pre‐ and post‐test scores regarding their understanding of each phase of PDSA improved 21.2% after completing the game. Additionally, the treatment group performed 16.6% higher than the control group. In participant perception questions, 85% of participants felt the game was more effective than lecture or reading, 93% felt the game was fun, 95% felt the game improved their understanding of PDSA, and 98% felt the game was engaging.     

Introducing B2B Service Level Measures via a Poker‐Card Activity

To determine the appropriate level of product availability, most operations management textbooks introduce and define service level measures in a Business‐to‐Customer context. In other words, a retailer that wants to measure product availability in their store calculates the fill rate (FR) or cycle service level over an infinite review horizon. However, in a Business‐to‐Business (B2B) context, a retailer almost always calculates the FR or compliance level over a finite review horizon. The goal of this article is to highlight calculations of service level measures in a B2B context. Pedagogically, it presents in‐class activities that use standard playing cards and/or a spreadsheet simulation that allow students to experientially learn about service level measures in a B2B context.     

The Flipped Classroom of Operations Management: A Not‐For‐Cost‐Reduction Platform

By delivering lectures online using screen capture technology, students can learn course material at the time and location of their choice, when they are in control to pause, rewind, and fast forward the professor. Class time is no longer spent teaching basic concepts, but rather focused on more value‐added activities such as problem solving, systems thinking and active learning, as well as potential collaborative exercises such as case studies, web‐based simulation games, and real‐world applications. A flipped classroom is an online course because its online components must compete with the best of the online courses. It is also a traditional course since not even a single class session is cancelled while all the lectures are delivered online. This core concept is reinforced by a network of resources and learning processes to ensure a smooth, lean, and synchronized course delivery system. Our pilot statistical analysis indicates that a flipped classroom, when implemented in a quantitative and analytical course, can outperform its alternatives.     

Sink or Swim: Learning by Doing in a Supply Chain Integration Activity*

Studies show that supply chain integration (SCI) is important to organizations. This article describes an activity that places students in the middle of an SCI scenario. The highly interactive hands‐on simulation requires only 50 to 60 minutes of classroom time, may be used with 18 to about 36 students, and involves minimal instructor preparation. Through the activity, students learn the basics of SCI and then analyze an SCI event to better appreciate the need for collaboration and information sharing. In courses that address supply chain management, instructors can use the activity early in the semester to introduce students to the complexities of supply chain networks. Alternatively, instructors may use the simulation later to provoke a more nuanced discussion.     

Proving the Usefulness of Demonstrations: Using M&M's to Develop Attribute Control Charts

Experiential‐based mini‐demonstrations are useful to facilitate student learning on a wide variety of topics. The purpose of this teaching brief is two‐fold: (1) it outlines a useful mini‐demonstration to teach attribute control charting when the sample size is unknown, and (2) adds additional proof that experiential methods positively impact upon student learning. The goal of this mini‐demonstration is to assist undergraduate and graduate students to develop their hands‐on statistical quality control charting and quality management concepts. By using this mini‐demonstration in one operations management class and not another, students that participated in this mini‐demonstration performed significantly better (p= .05) than their counterparts in testing. The mini‐demonstration may be extended to include computer integration, used in small or large class sizes, and provides an efficient, effective use of classroom time to develop concepts.     

Spreadsheet Modeling of () Inventory Policies

This teaching brief describes a method for finding an approximately optimal combination of order quantity and reorder point in a continuous review inventory model using a discrete expected shortage calculation. The technique is an alternative to a model where expected shortage is calculated by integration, and can allow students who have not had a calculus‐based statistics course to better understand how uncertainty affects inventory decisions.     

"Cola-Game": An Innovative Approach to Teaching Inventory Management in a Supply Chain

In this article we present a game that can be used as a tool to educate students and managers on the issues in supply chain (SC), inventory management. The game has a bilevel demand with one level during regular times and another during sale times. The game could be played in two modes (independence and cooperation) and has been field tested in engineering and business classes. Players developed an appreciation for fluctuating demand and its impact on the costs and performance of a SC. They also learned the benefits and a monetary evaluation approach for cooperation. Our statistical analysis revealed that, as the game progressed, the performance of the teams improved. We present an integer linear programming (ILP) model to evaluate the performance of the teams. Because it is a post facto analysis, while the game is played without knowing the materialized retailer demand for the period, the ILP solution is not a tight lower bound on the total cost of the SC. However, it could be used to compare performance across teams. As an alternative, we also present a possible distribution of total SC costs that could be used as another reference without actually solving an ILP.     

Patio Swings Intermodal Shipping Competition: An Inquiry‐Based Partial Information Exercise

Rather than providing all the required information as classroom exercises typically do, this international purchase and intermodal transportation competitive in‐class exercise intentionally holds back selected supply chain details. This inquiry‐based learning (IBL) approach simulates a real‐world Distribution Requirements Planning scenario by requiring students to identify what information they need and seek out those details from the instructor while competing with fellow student groups. In this 20‐30 minute exercise students are challenged to identify the all the necessary supply chain activities required to effectively ship patio swings from a supplier in China to a national retail chain in time for a spring sale. Generating the benefits of improved critical thinking in a fraction of the time required for traditional IBL, the approach is best described as a Partial Information Exercise. A student survey (n = 310) found that students strongly supported the inquiry approach, it generated significantly increased interest in global supply chain management roles and responsibilities, and over 91% of participants recommended the exercise continue to be part of the introductory operations and supply chain management course.     

Experiential Learning for Logistics and Supply Chain Management Using an SAP ERP Software Simulation

This teaching brief describes a three‐echelon supply chain simulation that involves complex decision making in a dynamic environment. Using a team‐based logistics simulation operating on a live commercial‐software application (SAP ERP) as a foundation, a supplemental exercise is proposed for deeper learning of transportation and logistics aspects of supply chain management. Sales and operations planning is used during four simulated months to develop detailed procurement strategies and logistics plans to enhance the baseline supply chain management (SCM) concepts of inventory control and forecasting in a distribution network. Transportation planning and scheduling complexity is introduced as students manage freight to conform to motor carrier weight regulations. The combination of commercial software and extensive real‐world planning allows students to assimilate numerous SCM concepts in a realistic environment. Student opinion survey data shows that students are highly engaged by the detailed nature of the simulation, which they concluded aided their conceptual learning. Additionally, the inclusion of the SAP ERP commercial software becomes a competitive advantage during collegiate recruiting by potential employers.     

Online Texts and Conventional Texts: Estimating,Comparing, and Reducing the Greenhouse Gas Footprint of two Tools of the Trade

Many universities are endeavoring to understand and reduce their greenhouse gas (GHG) emissions—or carbon footprints. Hard‐copy textbooks are (perhaps surprisingly) a large component of this footprint. Because they are “virtual,” electronic texts (e‐texts) are often considered environmentally superior to conventional hard‐copy texts. However, such claims lack thorough empirical validation. An effective tool for evaluating environmental impacts of products and services is lifecycle assessment (LCA). This article enumerates the steps in the lifecycles of conventional (hard copy) texts and e‐texts and it reports the potential GHG footprints of these activities. However, the actual footprint of most products and services depends on how individuals actually use them. Therefore, our second objective is to report survey results regarding actual student behaviors. Combining LCA and survey data, we estimate the GHG emissions of representative e‐texts and conventional texts; and we compare the two. This allows us to provide insight into the question, which alternative is best? Just as importantly, our analysis also identifies three levers that administrators, faculty and students can use to reduce text‐related GHG emissions.     

Collaborative Teaching and Learning through Multi‐Institutional Integrated Group Projects

This teaching brief describes an innovative multi‐institutional initiative through which integrated student groups from different courses collaborate on a common course project. In this integrated group project, students are asked to design a decentralized manufacturing organization for a company that will manufacture industrial Proton‐Exchange Membrane fuel cells. The groups include students from supply chain management, production planning and scheduling, and facility layout and design courses. Empirical results from the implementation suggest that students responded positively to the integrated experience. Lastly, the article presents implementation strategies for multi‐institutional group projects based on the experiences gained through the collaborative experience.
