Transportation waste is the
unnecessary movement of raw
materials, work-in-process or
finished products.
3
MOTION
Wasteful motion – by a person
or a machine. Motion costs
time and money. Machines get
worn out and people get
weary.
5
OVERPRODUCTION
Making too much or too early
of a product leads to excess
inventory.
7
DEFECTS
Any product that deviates from
design standards or from the
customer’s expectations and
has quality errors is called a
defect. Every defect requires
rework and this wastes
resources and materials.
2
INVENTORY
Over purchasing product
quantities that go beyond
supporting the immediate need
and leads to inventory waste.
4
WAITING
Waiting refers to the time when
work-in-process for the next
step in the production is
delayed and hence, no value is
being added.
6
EXTRA PROCESSING
This refers to any unnecessary
component of the process of
production. It adds more value
than the customer requires.
8
NON-UTILISED TALENTS
This waste happens when an
organisation fails to ensure all
their potential employee talents
are being utilised.
