- Supply Chain: 1. Starting with unprocessed raw materials and ending with the final customer using the finished goods, the supply chain links many companies together. 2. The material and informational interchanges in the logistical process stretching from acquisition of a raw material to delivery of finished products to the end user. All vendors, service providers, and customers are links in the supply chain.
- Traceability: Ability to trace the application, location, and/or history of an activity or item by means of recorded data.
Supply chainmanagement (SCM) is the management and coordination of all the inputs and outputs in the entire management process. It is important in order to increase efficiency and security. The following are the 5 general parts of a supply chain:
1. Plan— How a company is going to meet customer demand. This needs to be efficient, cheap, and should leave the customer with a high quality good.
2. Source—Where should the materials and services needed to make the product come from? Companies need to manage their inventories, and make sure shipments to and from manufacturing locations will be smooth and put on record.
3. Make—This is the manufacturing step. All the activities like testing, packaging and preparation for delivery need to be ready ahead of time. Companies want to be able to measure quality levels, production output and worker productivity in this stage as well.
4. Deliver—This is the includes all the logistics involved in getting the product to a store. It includes processing orders, establishing a network of warehouses, and hiring delivery companies.
5. Return—If there is a surplus or a mistake in an order, there needs to be a procedure in place for getting those items back. This step consists of transportation and warehouses on a flexible schedule.
Supply chains are vastly complex and wide spread, and become more so with increasing globalization. Many parts of the supply chain take place over seas because manufacturing in developing countries is substantially cheaper than in the United States because of the low cost of labor. Or security and efficiency reasons, every step of this complex chain needs to be monitored closely; but foreign manufacturing also makes it difficult to monitor data in other countries. Luckily, technology is making this easier, but it’s still expensive and can’t be used in all cases. 
Corporate Responsibility is the idea that corporations and businesses have more responsibilities than to their financial bottom line. Corprotions should conduct themselves in such ways that are not environmentally harmful or socially injust. This is another value of SPM and the technologies used in it.

Warm-up: How Do Things Get to Me?
- Begin this lesson by asking students to think about how the world is globally connected. Point out that we consume on a daily basis goods and services from all over the world. Ask students where the goods and supplies they see in the stores are made. Where do they originate? Answers will vary but make sure that students understand that many of these products come far distances. The materials that make up many of the goods we used must be collected and gathered from all over the world and then sent to one country to be put together and then sent to another country to be sold. Students should understand that goods and services travel many miles and go through the hands of many people before they arrive at the stores that we see them in.
- To appreciate globalization in modern society, tell students they need to understand exactly how many places a good (any physical thing you can buy) passes through before it is consumed. This is called the “supply chain” of a good. A supply chain includes absolutely every step in the process of making and transporting a good to consumers. It starts where the raw materials – like cotton, wood, iron, oil, etc – are grown, harvested or made. The raw materials are then taken to be changed, treated and made into different parts of a final product. The supply chain also includes the places where parts are assembled and all the storage places goods sit in before they are put on the shelves.
Activity One: Measuring On a Map
- Looking at a map, teach students how the scale works and demonstrate estimating distances using the scale. A scale is an indication of the relationship between the distances on a map and the corresponding actual distances.Draw two points on the board and label one as “store” and one as “home.” Draw an example of each type of scale listed below and demonstrate using each method to measure the distance between “home” and the “store”. Reference Reproducible #1 – Map Scales.
- The Graphic Method: A Graphic Scale is a line of reference that represents on one side the measurement on the map (ex. 1 inch) and on the other, what that inch represents in distance in the real world (ex. 500 mi). So one unit of measurement on the map equals another, much greater unit in real distance. To use this kind of scale, measure the scale on a ruler or on a piece of string, and then measure the distance between points on the map. Multiply how many units of distance you measured on the map by the distance one inch represents, according to the scale. In the example below, the scale represents 10 miles.
- The Verbal Method: The verbal method states in word-form what the graphical method represents on a line. It will say something like “One inch equals 500 miles” and the distance between two points on a map can be measured and compared to this scale.
- The Fractional Method:The fractional method describes the ratio between the map and the real world. It will appear as something like 1:10,000 or 1/10,000. This type is different from the previous two scales because it represents the same type of distance unit on both the map and the real world. If the scale is marked in inches, 1 inch on the map represents 10,000 inches in the real world. So to find out how many miles apart two points are, one would first measure the distance on the map, then multiply that by the second number in the ration (10 inches X 10,000=100,000 inches). Then one would need to convert inches to miles. where x=inches on the map. So mi.
- Draw two new points on the map and have students come to the board and practice using each type of legend.
Activity Two: The Journey of Jeans
- Explain to students that during this activity they will trace the supply chain of an every day pair of jeans
- Divide students into pairs and hand out a copy of Reproducible #2 – The Journey of Jeansto each student. Depending on preference and availability, hand out world maps to pairs, direct them to use a map in their text book, or instruct students to come up in an organized fashion to a large map on the classroom wall to do their measurements. Also, ask students to take out their own rulers and calculators (optional) or supply them for the class.
- Call on students to read aloud the first two paragraphs of directions found on the worksheet and allow time for any questions.
- Guide students as they work in pairs to measure the distance between countries and fill in the answers on Reproducible #2 – The Journey of Jeans.
- When the class has finished, call on each pair to read out an answer so students can check their measurements. Measurements will vary, but should be in the same ballpark.
- Ask students to think of ways this experiment was incomplete. Ask the following questions:
- Are there any other fuel costs not included in this calculation?
- Transportation paths wind through many different streets; they would not be in a perfectly straight line, and thus would use more fuel.
- There could be other methods of transport, like cargo ship.
- In reality, there are probably more intermediate stops between the distribution center and the store.
- Given the answers from #1, how can we expect the real fuel use to differ from our estimation?
- For the reasons listed in question 1, fuel use is probably higher than estimated.
- How might the supply chain for other products be different?
- May need more raw materials. For example, some electronics require toxic chemicals
- Assembly might be more difficult, mechanized, or dangerous.
- Packaging in plastic is usually a part of most other supply chains, which has a whole supply chain itself.
Activity Three: Innovations in Global Transportation
- Explain to students that a global market enables us to consume a wider variety of products and connect with cultures different from our own. As we saw in the last activity, it can also have profoundly negative affects, including a tremendous amount of fossil-fuel consumption. Another aspect of the global market that we have not yet talked about is demand. Companies must meet the demand of the market and it can be extremely challenging to coordinate the many different parts of the supply chain to make sure the store shelves are never empty. Up-to-date information, speed, and seamless coordination are key in keeping the supply chain running smoothly.
- Ask students to think about the journey of jeans they just followed and list the general steps in a supply chain and write the list on the board. Students should use critical thinking to infer what these steps are, with hints from the teacher if they get stuck. Steps should include:
- Extraction of all raw materials
- Fossil fuels
- Transportation of raw materials across the world
- Making raw materials into the disassembled parts of the product
- Transportation between factories
- Assembling of parts
- Transportation for inspection
- Transportation to the company’s warehouse
- Transportation to the store
- Ask students to brainstorm ways in which each step could be more efficient or less harmful to the environment. Possible answers include:
- Higher fuel efficiency
- Reducing transportation
- Shorter transportation routs
- Less packaging
- Safer or less polluting methods of manufacturing
- Now, discuss with students some of the ways companies are trying to be more efficient.
- Transportation costs are some of the most problematic issues in supply chain management. “Slow steaming” (a slowdown in speed in order to save fuel costs) causes some shippers to not be able to put their goods on ocean-going vessels, and, for pretty much everyone else to have their delivery schedules stretched out. Nowadays, companies are working to find solutions that will save them fuel costs without hampering productivity.
- Ask students how transportation costs could be minimized without compromising productivity. Answers should include:
- Increasing the fuel efficiency and aerodynamics of their transportation vehicles.
- Using alternative fuel sources.
- Choosing the shortest, most cost-efficient rout.
- Explain that using GPS technologies, companies can find the least-expensive routes for moving materials and goods. For example, companies might use this technology to reduce idling time at red-lights, take routes with the most appropriate speed limits and conditions, and keep drivers up-to-date on traffic and weather conditions, allowing them to make changes mid-route to avoid delays. This technology also allows companies to closely supervise their drivers to ensure they are making good time.
- Combining pick-ups and deliveries.
- Explain that companies are also using TMS (transportation management systems) programs to coordinate shipments and transportation routes. This technology allows retailers to see where it is possible to combine deliveries to stores and pickups at manufacturer and distributor locations on the same route. If the transportation vehicles are full both coming and going, companies save time energy costs.
- All these minute-by-minute monitoring systems also have positive affects in “traceability”- Ability to trace the application, location, and/or history of an activity or item by means of recorded data.
- Ask students why this might be important when transporting food. Answer should include
- It allows companies to know who handled the food and all the places it went.
- Explain that this allows regulators to track every person who ever had contact with the food and in every place, in case there is a disease outbreak, allowing it to be contained much more quickly. Grocers can also know the temperature inside food trucks at all times, and know whether it ever fell below safe levels.
- And the whole supply chain is kept moving by technology that enables retailers to monitor exactly what and when items are bought. When you go to the store and the cashier rings up an item you want to purchase, a computer sends a message back to the beginning of the supply chain so that a replacement item can immediately be made to make up for the one you just bought. This technology tells retailers how many of each thing to make, when shipments are needed, and what items are popular in which areas. That’s why the items in every Wal-Mart are not exactly the same! They are tailored to fit that area’s particular needs and interests, thanks to this monitoring technology.
- Global supply chain management is incredibly complex, like a many pieced puzzle. Technology and increasing options for fuel efficiency and alternative fuel use are helping companies successfully coordinate each leg of the supply chain and minimize costs for themselves and to the environment.
Wrap Up: Where Did My Shirt Come From?
- Have students check each others’ shirt tags to see where it was made. Students can also check where their shoes and school supplies were made.
- List the different locations on the board.
- Have students analyze the data by conducting a short discussion. Ask the following questions:
- What was the most common country? How many were made in the US? Answers will vary but most were probably not made in the U.S.
- Do they think that means the entire product was made in the US or just part of it?
- Why do they think so many things are made out of the US?
- Open a discussion about globalization.
- What are some of the advantages and disadvantages to a global economy? Possible answer include:
- A wider variety of goods and services
- Goods and services at cheaper prices
- May bring wealth to poorer countries
- Possibly better quality goods
- Fewer jobs in the US
- Poor or dangerous conditions for foreign workers
- Possibly poorer quality goods
- What are some potential economic and environmental effects?
- People may be able to buy more things because they are cheaper
- Foreign workers may be paid poorly
- The US has to pay another country for everything they import
- But the US gets paid for everything we export
- The long transportation costs a lot and is very environmentally taxing
Extension: Buy Local
- Explain to students that the lessons they learned today apply to everything we consume, from clothes to electronics to food.
- Challenge them to pay attention to the place of origin when they next go shopping and try to buy locally made items and locally grown food. Tell them were the closest farmers market is and encourage them to ask their parents to shop for some groceries there.
- Homework suggestion: Have students go home or to a public library where they have internet access. Have them go to http://www.trackmyt.com/to explore the journey one of their own t-shirts took. If they don’t have a t-shirt with a “Track My T” number, they can choose the “Track Random” option. Have them summarize what they learned about the journey of their shirt, to be handed in next class.
Students learned how to use the different forms of distance legends commonly found on maps. They traced the supply chain of a pair of jeans around the world, and estimated both the distance traveled in miles and the fuel consumption of the journey. By looking at where their own clothes and school supplies were made, students have come to appreciate how wide the global market is and have recognized their place in it. Students learned how their items get onto shelves and what it takes to keep stores stocked, and how companies are using technology to increase efficiency of transportation and decrease fuel use. After thinking about the pros and cons of a global market, students were challenged to buy locally made items.
