Lean Production
integrated activities designed to achieve high-volume, high-quality production using minimal inventories of raw materials, work-in-process, and finished goods
customer value
something for which the customer is willing to pay
waste
anything that does not add value from the customers perspective
value stream
value-adding and non-value-adding activities required to design, order, and provide a product from concept to launch, order to delivery, and raw materials to customers
waste reduction
the optimization of value-adding activities and elimination of non-value-adding activities that are part of the value stream
preventive maintenance
periodic inspection and repair designed to keep equipment reliable
group technology
a philosophy in which similar parts are grouped into families, and the processes required to make the parts are arranged in a specialized workcell
--eliminated movement and queue time between operations, reduces inventory, and reduces employees
quality at the source
philosophy of making workers personally responsible for the quality of their output. Workers are expected to make the part correctly the first time and to stop the process immediately if there is a problem
--workers become their own inspectors and do their own maintenance
The three lean layouts
-group technology
-quality at the source
-just in time production
JIT production
producing what is needed when needed and nothing more
--anything over the minimum is waste
--typically applied to repetitive manufacturing
--vendors ship several times a day
--exposes problems otherwise hidden by inventory
level schedule
a schedule that pulls material into final assembly at a constant rate
freeze window
the period of time during which the schedule is fixed and no further changes are possible
backflush
where parts that go into each unit are periodically removed from inventory and accounted for paged on production
uniform plant loading
smoothing the production flow to dampen the reaction waves that normally occur from schedule variations
Kanban
a signaling device used to control production
Kanban Pull System
an inventory or production control system that uses a signaling device to regulate flows

--requires determining the number of kanban cards (or containers) needed
--each container represents the minimum production lot size
--an accurate estimate of the lead time required to produce a container is key to determining how many kanbans are required
value stream mapping
a graphical way to analyze where value is or is not being added as material flows through a process
--needs a full understanding of the business including production processes
Kaizen
Japanese philosophy that focuses on continuous improvement
Types of waste
-overproduction
-waste of waiting time
-transportation waste
-inventory waste
-processing waste
-waste of motion
-waste from product defects
Components of a lean focused supply chain
-lean suppliers
-lean procurement
-lean warehousing
-lean logistics
-lean customers
