Postcompletion Phase

"wrap-up" reassignment of project resources

DRP

A time-phased planning approach that uses planned orders at the point of demand to determine forecasted demand at the source level is:

downstream supply partners' requirements.

Forecasts in a company using a distribution requirements planning system are typically based on:

bill of material

If a manufacturer had no inventory of any kind but had orders for 10 finished units of their sole product, their buyer would know what parts to order if they were supplied with a:

the single card is the production card.

In a single-card kanban system:

the move card signals when a container of parts should move to the next process step.

In a two-card kanban system:

overproduction

Inflexible or unreliable processes cause organizations to produce goods before they are required; this is called:

advantages of MRP (ch12)

MRP is directly tied to the master production schedule and indicates the exact timing and quantity of orders for all components MRP allows managers to trace every order for lower-level items through all the levels of the BOM, up to the master production schedule MRP tells a firm and its suppliers precisely what needs to be made when

special considerations in MRP (ch12)

MRP requires organizational discipline and accurate information MRP must be able to accommodate uncertainty MRP nervousness

concept phase.

Project planners develop a broad definition of what the project is and what its scope will be during the:

restocking level (ch11)

R

defects.

Scrap or rework are examples of the lean waste recognized as:

unnecessary inventory.

The delivery lead time was highly variable as was the quality of the product being shipped. These two factors combined to contribute to the waste of:

factory

The factory produces product and ships it to the distributor. The distributor sends it to the wholesaler when they receive an order. The wholesaler ships the product to the retailer as the retailer requests replenishment. The customer visits the retailer's bricks and mortar store to purchase the product when they run out. Which of these supply chain members is most likely subjected to the greatest variability in customer demand?

For the system to work properly, demand rates must be relatively stable and interruptions must be minimized.

a philosophy of production that emphasizes the minimization of the amount of all the resources (including time) used in the various activities of an enterprise. It involves identifying and eliminating non-value-adding activities in design, production, supply chain management, and dealing with customers can be applied to a wide range of production and service environments companies can and do use a wide range of planning and control techniques, not just kanban entirely consistent with business process improvement, quality improvement, and supplier management initiatives

material requirements planning (MRP)

a planning process that translates the master production schedule into planned orders for the actual parts and components needed to product the master schedule items managers dependent demand inventory which are inventory items whose demand levels are tied directly to the production of another item rough-cut capacity planning - a capacity planning technique that uses the master production schedule to monitor key resources requirements

service level (ch11)

a term used to indicate the amount of demand to be met under conditions of demand and supply uncertainty assumes that the demand during the reorder period and the order lead time is normally distributed

MRP nervousness

a term used to refer to the observation that any change, even a small one, in the requirements for items at the top of the bill of materials can have drastic effects on items further down the bill of material

Distribution requirements planning (DRP)

a time phased planning approach similar to MRP that uses planned orders at the point of demand (customer, warehouse, etc.) to determine forecasted demand at the source level (often a plant) instead of gross requirements, they show forecasted demand activities at distribution centers are synchronized when their total weekly planned orders become forecasted demand in the factory's master schedule

continuous review system (ch11)

an inventory system used to manage independent demand inventory where the inventory level for an item is constantly monitored and when the reorder point is reached, an order is released inventory levels are monitored constantly, and replenishment order is issued only when a preestablished reorder point has been reached the size of a replenishment order is typically based on the trade-off between holding costs and ordering costs the reorder point is based on both demand and supply considerations, as well as on how much safety stock managers want to hold

inflexible and unreliable processes

the waste of overproduction is caused by

inventory (ch11)

those stocks or items used to support production (raw materials and work-in-process items), supporting activities (maintenance, repair, and operating supplies) and customer service (finished goods and spare parts)

key characteristics of kanban (ch13)

uses simple signaling mechanisms to indicate when specific items should be produced or moved can be used to synchronize activities either within a plant or between different supply chain partners are not considered planning tools, but rather control mechanisms that are designed to pull parts or goods through the supply chain based on downstream demand

After a successful lean program (ch13)

wasted movement and space are eliminated and work centers are moved closer together inventory levels are reduced dramatically and work centers make only what is needed when it is needed
