Lean principles and practices
Toyota knowledge sharing across supply chain
Supplier Associations
Consulting Groups
Learning Teams
Types of operation (Monden)
non-value adding
waiting time, stacking intermediate products
necessary but non-value adding
walking long distances to pick up parts; unpacking deliveries
value-adding
sub-assembly of parts, forging raw materials
The seven wastes
(1) overproduction;
(2) waiting;
(3) transport;
(4) inappropriate processing;
(5) unnecessary inventory;
(6) unnecessary motion;
(7) defects.
The seven value stream mapping tools
Process activity mapping
Supply chain response matrix
Production variety funnel
Quality filter mapping
product defect
service defect.
internal scrap.
Demand amplification mapping
show how demand changes along the supply chain in varying time buckets.
Decision point analysis
Physical structure
which tools to use?
value stream analysis tool (VALSAT)
identify the specific value stream
identify the various wastes that exist
understanding the complete industry structure
recorded as row eight in the VALSAT
identify for each of the eight wastes/structure (D) the benchmark company in their sector
a normative method or production philosophy originating from Japan
five lean principles
Define value desired
Identify the value stream
Create flow
Establish pull
Pursuit perfection like the continuous seeking
The three lean approaches
is not only used in car industries, its origin fields, but also in other ar- eas like health care. Everywhere were waste is supposed to appear and efficiency is wanted to be increased lean can be a fine method to make things better, cheaper and faster.
lean is a system which offers a set of lean tools
an overall transformation plan is needed.
