KAIZEN
Appendix: Ten Areas that should be investigated for operational improvement (kaizen).
Here are ten things to think about for the
additional basic operations improvement process in general. The following list especially for
operations that involve manual labor, but it can also be adapted to other cases
as needed for the particular thought and effort.
1.
Can we fix the labor movement?
2.
Can we reduce the fluctuations in the time
element of work?
3.
Can we separate the manual labor out of
the engine?
4.
Can we revise the standard work in
process?
5.
Can we reduce the distance walked?
6.
Can we work with better balance among
workers?
7.
Can we improve the quality of processing?
8.
Can we improve the reliability of the
engine?
9.
Can we store, locate, and move the raw
materials more efficiently?
10.
What else should we consider?
A.1 Possible improvements to labor
movement
First, we will discuss improvements that
can be made in dealing with the labor movement. Depending on the skill level of employees,
major differences can occur on the job. So that operations can be done
efficiently, wasting the labor movement must be found and reduced.
Tip 1: learn to pay attention to your
posture employees to find points kaizen.
·
Do employees work with your back straight
or bent position?
·
Is changing the angle of his body
suddenly?
·
Can something be done while walking?
·
Is the direction of movement changed
suddenly?
Tip 2: learn to pay attention to hand
movements to find points kaizen.
·
Is the second hand move efficiently?
Whether there is a pause?
·
Is the movement the arms are too wide?
·
Are there only silence when your hands?
·
Is the job too high / low or left / right?
·
Is the final position is right? Whether
the movement is right for the next stage?
Tip 3: learn to notice the eyes to find
the point kaizen.
·
Is the body angle change suddenly?
·
Is the distance in hand with equipment and
components are correct?
·
Is the equipment, components, measuring
instruments in the correct position?
·
Is there a motion seeking or fumbling to
find something?
Tip 4: learn noticed foot to find points
kaizen.
·
Is there a movement away from the flow of
work?
·
Is there a job that requires long stop?
With the basics therblig analysis, you can
parse the movement of individuals who may require further kaizen lessons. You can also get ideas for kaizen by
focusing on elements and labor movements one by one. Try different techniques and see which
ones are best for different cases.
Here are questions to consider as well.
What would happen if we:
·
Change the angle of the tray rack
components or high?
·
Changing the number or size of the box
component palette?
·
Changing the size or height sliding board
or table?
·
Changing the position or angle tools,
jigs, or component?
·
Changing the order of jobs?
·
Changing the method of beginning the
process?
·
Reducing the number of trips by train and
other transport?
·
Using both hands?
All of the above can help you better by
cutting down the time of the work process and make the work easier and more
efficient at the same time.
A.2 Elements Focus on Working Time
Fluctuations
If you use the method of standardized time
study or work, there is often an element of time fluctuations in labor issues. The greater the volatility, the more
unstable elements and generally work harder.
Even when a job has been standardized,
there is often an element of work experience extreme fluctuations in time. Remember, if the worker experienced
fluctuating employment, fluctuations in inexperienced workers is definitely
bigger. Type of problem like this should be a high
priority. Here are some tips on things and the
things that need to be investigated to improve the work premises fluctuations
great time.
Is there trouble workmanship?
·
Are jobs hard to see, whether it takes a
lot to grope?
·
Is there much of an adjustment?
·
Are dibutuhakan a special skill?
·
Are there elements of muri / overload at
work?
·
Is the equipment easy to use?
·
Is the accuracy of equipment, supplies,
and so good?
Is the quality and shape of the resulting
components good?
·
Is there a faulty component is mixed with
other components?
·
Is good shape and precision components?
·
Is mudan components are removed from the
box?
·
Is rework happened?
Are there any parts wrong or missing?
·
Are the components in the specified
location?
·
Are the components displayed in a clear
and easy to see?
·
Is the standard of work / labor is
standardized?
·
Are the components shipped in small
quantities?
·
Is kanban cards are collected, sorted, and
components ordered?
Investigate thoroughly any points to
consider ideas for improvement and any points that need kaizen.
For the type of problem, the following
should be considered:
Improve the working methods
·
Fix adjustment takes work (eliminate the need for adjustment)
·
Simplify work requiring skill or
competence
·
Revision equipment, components, and so on
Stabilize quality
·
Increase the stability of the quality of
the components
·
Prevent faulty components into the box
·
Determine the location of equipment and
components specifically
Promote standardization
·
Make working standards and standardized
work
·
Follow workplace regulations
·
Create a rarely performed work that takes
place at regular intervals
A.3 Separating Work and Manual Work
machinery for Kaizen
Thinking about how to separate the engine
from the manual labor is an important concept in kaizen. Humans do not need to be a slave to the
machine and forced to oversee a process that has been created automatically. No one oversees grandchildren machine
cycle at work, for example. When the engine is running in automatic
cycle, there are many instances where people have to stand up and keep an eye
on the machine. This suggests opportunities for kaizen.
Look for opportunities for improvement
such as the following events:
·
Is there someone who has only watched the
machine?
·
After pressing the button "s tart", whether a person
should be waiting and watching for a while?
·
Do people need to hold or adjust the
equipment or workpiece position?
·
Is the ejector, slide, and transfer tool
work?
For these events, the following is
applicable:
·
Get rid of the work or the tray components
not required
·
Automated feeder components
·
Automate ejector components
·
Provide sled to move the components to the
next post
·
Improve and maintain tray damaged
components, jigs, etc.
A.4 Revise Standard Work in Process
In the manual lines, the location of WIP
(work in process) and the area of transfer of goods often arranged without
careful consideration. For each location of items that are not
needed in the process, a series of movements that are not needed will also
occur.
·
Is the standard of work in process are set
correctly?
·
Is the standard work order followed?
·
Is the item in the process really
necessary?
·
If the goods required in that process, can
be limited?
For this situation, you may try the
following:
·
Set in such a way that only the correct
amount of raw materials that may be placed
·
Clarify visually how much material should
be placed
A.5 Reduced Distance Running
In the line of manual labor, often
arranged layout with emphasis on equipment that causes activity goes in vain. Or a combination of volume and product
changes over time, and the layout are now no longer optimal from the standpoint
of walking activity.
Focus on the following to reduce the
activities of running:
·
Is the distance between the point of running away?
·
Is the walking track between the points straight?
·
is there anyone who pacing?
Try the following to reduce the activities
of running:
·
Change the layout to better accommodate as
far as possible
·
Change the location of pallet rack
components and parts
·
Get rid of unnecessary barriers
A.6 Work Balance
For operation with many employees working
together, the work done, everyone is different, and the time required is not
balanced. This arrangement often creates a situation
where some employees are overloaded when compared to the others. Alternatively, some operators may have
idle time (idle time) are significant.
For cases like this, the best practices that
we can propose is to use a combination chart standardized work and workload
carefully charted every one in detail. Identify key tasks and work elements of
each person. Do a study of the elements of time and
make comparisons between the operation in question. Balance work with the most efficient
manner possible by moving elements from one process to another as far as can be
done.
However, although it sounds strange,
remember that you do not necessarily want to balance operating in a completely
evenly. The reason is that, for the maximum
efficient, you want to balance work and runway work wherever possible. In the case of area or production line
with seven people, for example, the last may not have a total work in
accordance with the runway work. For cases like this, you can balance work
six people first, and let the seventh perform whatever work is left. After a while, you can find ways to reduce
operating last through kaizen. For the short term, workers can do the job
rotation to ensure equal opportunities and safety.
A.7 Quality Improvement
There are unlimited opportunities to
improve quality in kaizen. Indeed, you could choose to directly use
the problem-solving activities in this regard. However, kaizen is also an effective way
to consider the improvement of quality in many cases. The following are some general points to
keep in mind when working with issues of quality in kaizen activities:
·
Provide a simple red box near the
production line to keep the defective items for quick analysis
·
Simplify the process associated with the
daily record types remaining ingredients and rework
·
Explain the principle of 80/20 to
determine the dominant type of damage
·
Set clear rules for handling the product
damaged / defective
·
Find a way to prevent minor damage such as
scratches, nicks or grooves
·
Consider packaging changes to address the
problems associated with handling
·
Find a simple change to the design of
components or processing methods
·
Maintain the cleanliness of the work area
to prevent problems associated with contamination
·
Find simple ways to improve process
capability
·
Ensure that the replacement of equipment
and quality checks performed in a timely manner
·
Simplify the measurement and inspection of
components
A.8 Possibility Repair Equipment Reliability
As with quality, there is the possibility
of equipment repair and maintenance is limited in kaizen. In this workbook, we discuss six major
equipment losses in the process and it is a great place to revisit the idea of
improvement. Here are some points to be reviewed when
considering kaizen in equipment intensive area:
·
Create a database of all the damage heavy
equipment to study the recurring problem
·
Mark about five machines as a priority for
improvement. It is often a good place to start
·
Operations and maintenance personnel
interviewed to find brief cessation sometimes slip through the cracks tracking
system
·
Apply observation equipment in one or two
shifts. It will also highlight the problem of small equipment that's sometimes is missed by the tracking system
·
Compare damage equipment with preventive
maintenance action for the equipment. Identify what works and what does not work
·
Find a simple visual inspection tasks that
can be done without stopping the machine operator
·
Fix 5S conditions in and around the engine
·
Try and make pins abnormal conditions
(such as low fluid level, high temperature readings, etc..)
·
Do a study of the machine cycle time and
see if the machine is still working according to the design
·
Learn the process of replacing any
equipment or mold (die) and look for areas to simplify the process
·
Investigate losses due to residual
materials, workmanship and over, or the loss of the initial results and look
for ways to minimize such losses
In addition to the focus area of this
equipment, you can also observe the work of maintenance personnel and look for
ways to improve this area as well. For example, the following areas can be
studied for improvement:
·
Fix data set for analysis equipment damage
·
Find the most frequent maintenance
sessions and simplify repetitive tasks
·
Make study time on some sort of
maintenance sessions. Describe the repair time and saw
extravagance or difficulties that occur
·
Usually, there are tremendous
opportunities to improve the image engine, electrical circuit diagrams, parts
lists, and communication in general practice
·
Fix the component storage area and
minimize the time required to find the tools and raw materials
·
Analysis of preventive maintenance
schedules and effectiveness
·
Make sure all the special tools needed for
maintenance are available
Another improvement opportunities also
exist within the scope of equipment and maintenance. Add to this list according to your own
unique situation.
A.9 Possible Improvements Flow Raw Materials and Storage
Most of the problems associated with the
flow and storage of raw materials can be found by drawing a diagram of raw
material flow analysis and good information. The technique is a common starting point
to identify opportunities for improvement in this area. The following suggestions may also be able
to give you some extra points for consideration:
·
Review the containers and container size
in relation to the quantity of demand
·
Review the number of times the raw
materials handling section to move and get rid of stuff
·
Consider minimizing the storage location
and the amount of movement of goods related
·
Label the location of storage of raw
materials and write clearly the name, type, and quantity of goods stored
·
Create a naming scheme for all parts of
the plant that can identify the location of storage of raw materials with ease
·
Paint the room air so high inventory
shortages can be seen clearly
·
Consider a special way for functions that
have a high need for raw material handling. Keep pedestrian paths did not get into
this area
·
Calculate the amount of inventory of any
special storage location with respect to the cycle, buffer stock and safety
stock
·
Set rules and guidelines for the use of
buffer stock and safety stock
·
Review the material flow characteristics
in the area and determine whether the system pull (pull system) type of
recharge (replenishment), respectively (sequential), or mixed (mixed) can be
applied
·
Review the principles of materials
handling and determine whether the system is based on the quantity or based on
a more appropriate time for delivery
·
Learn the routes and handling of raw
materials as well as the identification of the point of the problem areas for
improvement
A.10 Other Improvement Areas
Potential areas for improvement using
Kaizen are endless. In fact, you will only be limited by your imagination
and the time available to spend on this topic. Simple workbook is designed with a focus
on methods of Toyota in learning basic production processes and initiate
improvements in this area. The following areas may be helpful to
consider according to your situation:
·
Consider energy costs and plan how to
reduce all costs associated with energy
·
Improve lighting and cleanliness of the
work area
·
Learn oils, lubricants, other liquids, or
other complementary items used in the process and find a suitable replacement
item can be used
·
Fix and prevent lubricant leakage and air
·
Fix attention to safety and accident areas
with a history of recurrent
·
Learn the overall delivery of raw
materials to the plant in terms of logistics efficiency
·
Identify jobs that may be more
appropriately carried out by the supplier or the cases that should be handled
·
Review the basic aspects or assumptions
relating to the design of products. Find something simple that can be changed
to make production easier
·
Evaluation of simple changes to equipment,
measuring instruments, mechanisms dibble, or other devices to improve function
·
Learn about the production process as a
whole and think of new processing methods that may be made in the future
·
Fix documentation surrounding the process
as standardized work, technical drawing, or document maintenance, and others.
