Referring to the last-named item, Canady noted that Dell takes all of its employees into a week's training on lean to solidify lean culture throughout the organization. On the transportation side, overnight shippers come to the same conclusions when they recommend that the way to reduce inventory levels is to know where the inventory is and how long it will take to ship it. But his would be a flawed strategy for e-commerce and now also for business in general since customers are coming to expect product to ship within 24 hours and can quickly scan the web for quicker competitors. Another aspect of flow manufacturing is the dedicated cell or line, which may be arranged to build any variation within a product family without any setup. Part variety can be further reduced by consolidating many inherently inflexible parts into a few very versatile standard shapes; this would apply to raw castings, molded parts, stampings, extrusions, custom silicon, power supplies, and bare printed circuit boards. Typically, the manufacturer uses orders received from the retailers' warehouses to forecast demand.
Kanban is a versatile technique that enables automatic resupply of parts that can be made in batches or have not-quite-spontaneous delivery times. Examples suitable for a Build to order system Not all products and industries are suited to adapt build to order systems, but some mainstream industries and manufacturing businesses do adapt a build to order system for some of their most exclusive or specialised products. Through application of such a system, the organization can receive real-time demand information that can be used to develop and modify production plans and schedules. Unfortunately, demand rarely coincides with forecasts, and results fall short of expectations. Of course, the parts manufacturers may have to implement setup reduction to make small batch production economical. However, this system may be prone to wastage and obsolescence, as inventory sits on shelves awaiting purchase. The Missing Link in e-commerce The internet and sophisticated software permit manufacturers to process an endless stream of individual orders almost automatically.
. Mass Customization; the proactive management of variety Mass Customization of variety. Hence, this concludes the definition of Build to Stock along with its overview. This model requires careful management of the component inventories and delivery of needed supplies along the supply chain. The products and processes may have too many setups designed in.
They are not assigned according to specific sales orders. So they learned how to print face plates in small quantities to complete the picture. While customers still want their computers right away and at the best price, the customization angle is no longer a crucial part of the model. Their focus then becomes how to get rid of stock and how to offset the cost to manage it. Profits erode, and customers do not get what they really want. This means that the end consumer dictates when and what products will be produced.
In this model, the parts of the product are gathered and assembled as the product moves through the distribution channel. Push Strategies A push-model supply chain is one where projected demand determines what enters the process. A typical European short-haul flight has nine major pricing categories, which can yield more than 100 ticket prices for the same flight. Total cost measurements Most of the above steps, viewed narrowly, may appear to be more expensive, and therefore may be resisted. What's more, that culture is shared with suppliers. Products start out as raw materials. However, the assemble-from-forecasted-parts model works only for modular products and may not be viable at low-to-medium production volumes.
Trying to satisfy spontaneous orders from forecasted inventory is not compatible with the pace and breadth of e-commerce. Some firms build all their products to order while others build them to stock. Ultimately the customer must pay for carrying cost of the inventory which over the last twenty years has averaged about 25% of inventory value per year. Rationalization may appear to lower sales; Standardization and consolidation may appear to require most products to use better materials than they need; The lack of competitive bidding inherent in may appear to raise procurement costs; Reintegrating unfamiliar processes may appear to be less efficient than using specialists; Small batches, approaching one, and dedicated flow lines using simple equipment may appear to be inefficient from a mass production standpoint. The focus too often becomes simply how to make the shop floor more efficient, rather than how to optimize the whole system. Larry Downes and Chunka Mui, Unleashing the Killer App, Digital Strategies for Market Dominance, 1998, Harvard Business School Press , p.
From the viewpoint of supply chain management, it has been proven that those who can satisfy due dates promised with customers and can shorten lead times will have an competitive advantage. For example, in some cases, the process of assembling prepared parts starts when actual demand occurs. Part variety can be further reduced by consolidating many inherently inflexible parts into a few very versatile standard shapes; this would apply to raw castings, molded parts, stampings, extrusions, custom silicon, power supplies, and bare printed circuit boards. This can be generated through an or manually. The problem with this strategy is that it depends on forecasts from outside the manufacturer's control.
A local supplier is contracted to simply keep the bins full and bill the company monthly for what has been used, much like the way bread is resupplied by the breadtruck in a small market. This integration is often achieved through use of an information system that is fully integrated an enterprise system. A third way to build products to-order for e-commerce is to draw parts from forecasted inventory and assemble-to-order modular products. The resupply is automatic once the pull signal gets to the supplier. The build to order system is usually reflected throughout the supply chain and suppliers also operate a similar on demand system, and information on consumer demand trends tends to be shared to better balance production and achieve. In hair care alone, it slashed product offerings in half and grew market share by 5 percentage points. Build to order enables the manufacture of any quantity of standard products on-demand without forecasts, inventory, or purchasing delays with unique methodologies.
