what is the impact on return rates (and thus reverse logistics) due to the growth of e-commerce?
Returns can represent significant challenges to a supply chain. In many cases, reverse logistics is viewed as an unwanted activity of supply chain management. In these cases, reverse logistics is seen simply as a cost of doing business or a regulatory compliance issue. Problems include the inability of information systems to handle returns or monitor reverse product flow, lack of worker training in reverse logistics procedures, little or no identification on returned packages, the need for adequate inspection and testing of returns, and the placing of potentially damaged returned products into sales stocks. A poor reverse logistics system can affect the entire supply chain financially and can have a large impact on how a consumer views a product brand, potentially impacting future sales. Some recent studies indicate the real costs of returns take up roughly 3 to 5 percent of total revenue. From a marketing perspective, an effective returns process can create goodwill and enhance customers' perceptions of product quality and purchase risk. From a quality perspective, product failure and returns information can be used by quality personnel in root cause analyses and by design personnel to reduce future design errors (the number one reason for a product return is a defective or damaged item). From a logistics perspective, returned products can still create value as original products, refurbished products, or repair parts. This also tends to reduce disposal costs.

what is public warehouse?
an independent warehouse that is operated as a for-profit. contract out or lease a wide range of light manufacturing, warehousing, and distribution services to other companies. Public warehouses provide a number of specialized services that firms can use to create customized shipments and goods. Public warehouses provide the short-term flexibility and investment cost savings that private warehouses cannot offer. If a firm's demand changes or its products change, the short-term commitments required at public warehouses allow the firm to quickly change warehouse locations. Public warehouses allow firms to test various market areas and withdraw quickly if demand does not materialize as expected. The cost for firms to use a public warehouse can also be very small if their capacity requirements are minimal. One of the main disadvantages associated with public warehouses is the lack of control provided to the goods owners. Other problems include lack of communication with warehouse personnel, lack of specialized services or capacity at the desired locations, and the lack of care and security that might be given to products. Firms might find it advantageous to use public warehouses in some locations and private warehouses in others. For large, established markets and relatively mature products, large firms may decide that owning and operating a warehouse makes the most sense, whereas the same firm may lease space and pay for services at public warehouses in developing markets and low-demand areas.

why the toyota production system includes visual cues so heavily?
- Visual communication is the most effective means of communication people understand the message quicker, and with great comprehension than any other means of communication.

what is a kaizen blitz?
A rapid improvement event or workshop, aimed at finding big improvements
why some companies have tried to implement the toyota production system but had limited access?
Companies often fail because they do not realize that you need to put the entire system in place, and not just bits and pieces of it, to gain the same type of culture and process improvement that Toyota can boast of
what is small-batch scheduling?
Drives down costs by: - Reducing purchased, works in progress, and finished goods inventories - Makes the firm more flexible to meet customer demand
what is LTL?
LTL carriers move small packages or shipments that take up less than one truckload and the shipping fees are higher per hundred weight than TL fees, since the carrier must consolidate many small shipments into one truckload and then break the truckload back down into individual shipments at the destination for individual deliveries. For many shippers using LTL carriers is a much less expensive alternative using a TL carrier
How logistics strategy should be tied to larger corporate goals - and the types of goals most directly relevant to (and affected by) logistics
Management first defines the organizations visions and goals and then logistics strategies are designed to ensure achievement of these goals. It should be a two-way connection. For global goods movements, logistics managers must be aware of a number of issues not impacting domestic movements such as regulatory requirements, import/export limitations, port and warehousing issues, and the modes of transportation available. Poor logistics management can literally bring a supply chain to its knees, regardless of the production cost or quality of the products. Alternatively, good logistics management can be one of the elements creating a competitive advantage for supply chains.

Most kaizen improvements though, are small individual events, emphasizing creativity

true
True or False: when lean firms share their best practices with supply chain member, this is referred to as yokoten
true
what is excess movement?
unnecessary movements of employees
what is overproducing?
unnecessary production to maintain high utilizations
what is private warehouse?
warehouses that are owned by the firm storing the goods. For firms with large volumes of goods to store or transfer, private warehouses represent an opportunity to reduce costs of warehousing as well as control levels of service provided to customers. firms are free to decide what to store, what to process, what types of security to provide, and the types of equipment to use, among other operational aspects. Private warehousing can also enable the firm to better utilize its workforce and expertise in terms of transportation, warehousing, and distribution center activities. As supply chains become more global to take advantage of cheaper sources of supply or labor, the use of private warehouses tends to increase. Finally, private warehouses can generate income and tax advantages through leasing of excess capacity and/or asset depreciation. For these reasons, private warehousing accounts for the vast majority of overall warehouse space in the United States. Owning warehouses, though, can also represent a significant financial risk and loss of flexibility to the firm. The costs to build, equip, and then operate a warehouse can be very high and most small- to moderate-sized firms simply cannot afford private warehouses. Private warehouses also restrict firms to locations that may not prove optimal as time passes. Warehouse size or capacity is also somewhat inflexible, at least in the short term. Another problem can be insurance. Insurance companies, in many cases, do not like insuring goods in private warehouses, simply because security levels can be meager or nonexistent, creating a significant concern regarding fires or thefts of goods.
what is consolidation warehouses?
warehouses that collect large numbers of LTL shipments from nearby regional sources of supply then deliver in TL or CL quantities to a manufacturer
