Defects
Defects affect customer satisfaction, energy, manpower,
resources, and money. Examples of
deficiencies in a manufacturing environment include lack of adequate
documentation or specifications, significant variances in inventory, poor
design and related changes in design documentation, and general lack of proper
quality control throughout the workflow process.
Documentation for formalized document control and design
change, detailed and documented quality methods in all production stages and
audited lists in order to ensure proper compliance with the BOM are effective
ways to control waste defects. And
standardized work at every production cell or point in the production line will
also, help to reduce this kind of waste.
Common defects include:
Poor quality control at the manufacturing level
Poor machine maintenance
Lack of adequate documentation
Quality management
Not knowing the needs of your customers
Overproduction
If parts are assembled before the next downstream phase
needs them, overproduction occurs. There
are several negative effects on this. It produces a "caterpillar" the effect in the flow of output which results in the creation of excess WIP. This
results in the scheduling and therefore the effort required to move the
additional periods of the WIP. And it can mask bugs that might have been found
with less scrap if processes were designed to enable quicker identification
because early use of WIP components would have exposed the flaw in time to
correct the problem.
Takt time is used to even out levels of output between
cells or divisions. Measured and
process-mapped jobs lead to reduced setup time allowing effective small batch
flow. And the "pull" systems
such as Kanban can be used in many industries to help control or eliminate WIP.
Common causes of overproduction include:
Inefficient method
Unstable production schedules
Inaccurate prediction and demand information
The needs of the customer are not apparent
Waiting
Waiting can include people, material equipment
(unfinished prior runs) or idle equipment (mechanical downtime or excess
switching times). In terms of direct
labor dollars, all the waiting costs a company has, and additional overhead
costs can be incurred in terms of overtime, expediting costs and parts. Waiting can also cause additional waste in
the form of defects, if the waiting triggers a flurry of activity to
"catch up" which results in non-compliance with standard work or
shortcuts.
Waiting is in many ways the reverse of
overproduction. With many of the same
treatments, it can, however, be mitigated or removed. Waiting is often the result of poor process
design and can be solved by proper takt time measurement and standard work
formation.
Common causes of Waiting include:
Unplanned downtime
Idle equipment Short
Set-up times Long or delayed set-up times
Lack of process control.
Non-Utilized Talent
The eighth waste is the only lean waste generated that
isn't unique to the manufacturing process.
This form of manufacturing waste arises when management fails to ensure
that all its potential employee talent is exploited in a manufacturing
environment. The waste has been
incorporated to encourage organizations to integrate staff creation into the
lean ecosystem. As a mistake, this can
result in assigning workers the wrong tasks or tasks they have never been
properly trained for. This may also be
the result of poor relationship management.
The overall organizational efficiency is enhanced by
engaging workers and integrating their innovations, offering training and
growth opportunities and involving them in developing process improvements that
reflect the reality they encounter and the skills they possess. Removal of this type of waste may improve all
others.
Types of Unused Talent: Poor communication Failure to
involve people in workplace design and development Incomplete steps Poor
management Failure to involve people in workplace design and development.
Transportation
The bad plant design will result in transport
waste. It can also cause other waste
such as waiting or moving and affect overhead costs such as higher fuel and
energy costs and higher overhead labor in the form of lift drivers, as well as
adding wear and tear to equipment. It
can also be the result of poorly designed processes or processes that have not
changed or updated as often as necessary.
Quality stream mapping and partial or complete factory
layout improvements will reduce the transport waste. This is a complete documentation of all
aspects of the flow of production and not just a mapping of a specific
process. This leads to changes to reduce
or eliminate the waste from transport.
Common types of transport waste:
Poor layouts
Distance between operations
Long material handling systems
Wide batch sizes
Multiple storage facilities
Inventory
Due to the associated storage costs, inventory is
considered a form of waste. This applies
to raw materials, to WIP and finished goods. Purchasing or poor forecasting and
planning may result in waste from inventories.
It may also signal a broken or poorly designed link between production
and purchase/scheduling processes. In addition to focusing on the factory, Lean
Manufacturing also requires process optimization and communication between
support functions.
Common causes of inventory waste include:
Overproduction of products
Production delays or ' waste of waiting '
Inventory defects
Transportation excessive
Motion
Mobility costs money.
That includes not only raw materials but people and equipment as
well. It may also require unnecessary
physical movement, such as reach, lift, and bend. Any excessive motion results in time with no
value-added and increases costs.
Again, with reference to the core Lean Manufacturing
methodology, the process mapping should include facility layout and optimized
design of the workplace, including an analysis of the distance of movement
within the space and even the location of components, materials, and
instruments throughout the space. With
the development of an effective process map, proper use of the space can be
captured with well-designed and documented standard work.
Examples of common motion waste include:
Poor workstation layout
Bad production planning
Poor process design
Shared equipment and machines
Silo operations
Manufacturing standards lacking
Excess Processing
Excess processing is a sign that a process is poorly
developed. This might be related to
management or administrative issues such as lack of communication, data
duplication, overlapping authority areas, and human error. It may also arise from the construction of
the facilities, insufficient workstation tooling or the layout of the facility.
System mapping is a lean waste disposal tool that helps
identify an automated workflow that can minimize processing over time. System mapping is not limited to conducting
manufacturing tasks as the main tool of lean development. It also involves the
recording of records, sign-offs, and papers.
Excess processing examples include:
Poor communication
Not knowing the needs of your customer's
Human error
Slow approval process or unnecessary
