Layout Team Achievements
Clearer lines for product flow
Improved visibility in department
Completed tint jobs flow to sorting
No more walking for loaders!!
Now have room to expand capacity
Visual controls for WIP using Kanbans
Lighting improved at workstations
Repetitious Work – Layout Team
Every person had a different technique for
Wearing gloves or not
Cloths they were using
Lens cleaning and Loading
These were actioned itemed, as were;
Workflows with kanbans
Handling rejects
Error-proofing and timings
Glove, No Glove
New SOP on wearing gloves:
Team members on lens cleaning and lens loading to wear a pair of
Nitrile gloves – to protect wearer from sharp edges and exposure
to methnol, and to protect the lens from fingerprints and markings
Different Wipes
Decided to use 1 type of cleaning cloth only – the Blue Chicopee
wipes. All white cloths were removed from all work areas.
An action item list is to test 4 possible cloths; based on
performance and cost.
WIP Removed
Work In Progress before, later the work was processed and many of
the racks were removed for the final layout
Proper Loading of #8 Jobs
The first space
is empty
All clip hangers
are correctly in
the grove above
The #8 clip
is used
Equal spacing can be seen on the
bottom at each clip
How Racks Might Come from Cleaning Area
Here, the clips are in the closed
position. Having them like this
will prevent them getting hooked up
Here, the clips are in the open
position, the arms can get tangled
when removing them to load the
clip.
Jig or No Jig, That is the QuestionIn January the jig was used by most people. Notice the failure rate downstream in sample one of Test of Proportions (n1).
In April, very few used the jig. Notice the failure rate downstream in sample one of Test of Proportions (n2).
Conclusion: using the jig does not appear to have an impact on downstream failures.But ….. Does the jig reduce cycle time?

Jig Test – 12 Lenses in Each Test
Jig Use Finding:
Cycle Time = 1:57
Rework = 0
Observations:
• Good
• Less likely to scratch lens
• Sat securely
• Did not look hard to do
No Jig Use Findings:
Cycle Time = 1:16
Rework = 1
Observations:
• Ida had a great technique
• Looks more difficult to new workers, both to do and in scratching lens
• Might be tilted
Final Decision: Jig. We will adopt an SOP that address the non-jig people
To make using the jig the best it can be.
Proper Jig Use
Proper use of the jig
Note how long the clip goes down into the jig
The clip arms are in the wheels each side of the jig
The arms will open and the lens can be easily placed in the correct position
Proper Loading of Clip on Jig
Sometimes loaders would allow
The clip arms to twist when loading
Clip arm has
to be is the
groove of the
wheel
If the clip arms are flat
against the back of the jig
the arms WILL go in
the wheel groves
Error Proofing of Jig
Adding a space on the top of the jig
allows for the top of the clip to be
braced during the loading of the clip
The side view shows the thickness
of this spacer.
Another Error Proofing of the Jig
To ensure the proper placement of a FT in the clip, lines were drawn on the jig.
If the operator lines up the top of the FT to the lines, either over them or parallel to them, it will be at the correct 300 angle
Proper Loading of Lenses on Holders
To load property
the narrow end of
uneven lenses need
to be on the bottom, the
wide area on the side
65 and CR Clips
Clip used to 65 size lenses.
Note the Yellow Color at top
Clip for CR, note the blue color at
the top

Goals of the group
Determine gaps in current system
5S, Visual Controls Goals
To set the standard for workplace organisation
Implement procedures to ensure consistency
Positively effecting workplace safety, product quality, production cycle times and capacity
Supporting Visual Factory Management will develop the model cell for the rest of the plant to benchmark
All this will be achieved by using the most simplistic methods possible interviewing all involved in the set-up and ultimate decisions.

5S, Visual Controls Team Action Items
Incoming AreaBefore Picture
Work on the floor, tripping hazard,
too much WIP.
After Picture
Limited amount of work is stored
in the incoming racks, all are sorted
before going to the loaders
Dipping Waste and Throughput Board
Before Picture After Picture, this is located in an
area better seen by the workers
Boards in the Area
Before Picture
Clutter on boards. Not standardized. Needs to be In the best place for all to see.
5S the boards, place in a good spot with just the info we need on it.
The Area has Signage with Clear Goals for All Involved
You are entering a Set – In – Order Zone Area Goals
Yellow Line Removal
Before:Small area to work, items for process
have no clear home
SOPs covered
by all the WIP!
Inlet Rack to Load Area
Before Picture
Too much WIP, not clear on prioritized
work, flow is impeded, difficult for loaders
to access.
The New Layout has a Major Reduction of WIP
Only this side of
the inlet trays have
lenses, the other
side are empty trays
for recycle to grind
A small number
of lenses will be
in queue in tinting
A limit of 6
trays are to be
at each of the 2
stations.
Tint Area - Before
Before Picture
No clear direction
of flow, too much
stuff, disorganized
stuff on the floor,
no clear SOPs.
Tint Samples
Before - these racks were in the wrong
order, could fall down, and added
clutter to the area
After - the racks are numbered, in the
Right order and mounted In the packets
they came in.
Load Work Station at Shift Start -Before
Before Picture
Inconsistency in the work stations. They look really clean at the start of
Each shift, but take on a different look when works starts. Need to perform
5S and standardized work station layout and procedures.
Two Different Work Stations
Load Area
Materials used at Cleaner and Loading Station
Methanol and wipes for cleaning Rack tags and rubber bands to tie
up the grind cards
Load Station Before
Methanol container is to the upper
left and operator is right handed,
this increases the stretch.
Before Picture
This work station looks different from
others. Need 5S and standardized
work stations.
Load Station Before and After
Before Picture
Jig is not used in this work station
This workstation
looks different from
others. Need 5S
and standardized
stations.
After Picture
All items in the station are used on
a daily basis, are in places designed
by line workers
Loading Scanner Location
Before Picture
No place for the scanner and mouse, no table to place products to scan them
AND see the monitor at the same time.
Handling rejectsNo clear
procedure for
dealing with
lenses that have
scratches:
Most people
place in a
tray, the under
the desk, and
chase Supervisor
for a 2nd opinion
Now have a
central point for
any defect lenses
found at loading
– Supervisor
knows where to
look for any
problem jobs
Before Picture After Picture
Clips / Lens Holders
Before Picture
Different holder types Holders are stored in a haphazard
manner from cleaning process in
the bins
Materials Storage Area
Before Picture
Holder bins and marks in the storage cabinet. Needs 5S and visual controls
that can be seen and used.
Supervisor Station
Before Picture
Supervisors station is full of clutter and easy access to the MSDS books.
Area needs to have 5S done and only the items needed in the area.
Supervisor Station After
Justino is performing 5S in the desk

Final work, everything here is NEEDED.
has a home and is in it’s home.
Conveyor and Extra Storage
Before Picture
Remove the
board where it
is needed, if
it is needed. Might
use just the SOPs
on the board.
Extra storage area might need to be moved
or removed. 5S will sort this item, placing
it in the Red Ticket area, if layout wants it,
we can bring it back.
Marking the Conveyor
Before, it was not clear where to place
racks on the conveyor.
After, the GREEN area shows where
The racks are to be placed.
Cleaning of lensesSOPs not given importance in old
layout
In new layout SOPs are given more
visibility
Workflow is now obvious
No clear workflow, lots of unnecessary
motion
New SOPs use as little motion as
possible, influencing the new desk

How the Kaizen Team Feels Sustainability will be Accomplished
Communicate with members consistently
Positive encouragement
Lead by example
Keep explaining!
Collect feedback – promise to review in 2 weeks time (allow time for acceptance)
Spot checks! – by the Supervisor
1-to-1 training on new technique; for the first week, give refresher training daily
Next Steps – Wish List
Place two more tables in the loading area, making it possible to add 2 people to the area to process more product, IF NEEDED
Extend the conveyor down to the 2 new tables
5S the cleaning of clips area since our work cell members work in their as well – another Kaizen might be needed to do this
Install an LCD display board for Lenses per hour per person
