Layout Team • Team Members – George – Julie – Lira
Layout Team Repetitious Work SOPs, New Layout • • • • • • • • Draw up action items list Revise existing flow map New SOPs for repetitious work Key aspects of new layout Determine gaps in current system New work process cycle times New lead times with new layout Potential Layouts, and prioritize selection
Objectives of Flow • • • • • Reduce work in progress (WIP) Eliminate unnecessary travelling Eliminate unneeded separation of work Cost to Implement Easier access to conveyors for loading staff • Allow for better flow of tinting jobs • Reduce lead time • Balance the line

New Work Stations
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
Layout Team – Repetitious Work • Team Members – Alan – Josie – Anita
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
Different Wipes and Glove, No Glove
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.
Proper Cleaning Methods Correct gloves and cleaning towel
Work Stations Before
WIP Removed Work In Progress before, later the work was processed and many of the racks were removed for the final layout
Old way of Loading of #3 Jobs CR
Proper Loading of #8 Jobs The first space is empty The #8 clip is used All clip hangers are correctly in the grove above Equal spacing can be seen on the bottom at each clip
Proper Loading of #9 Jobs
Process Book Number Completed Process Book Number Process Book Number
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 Question • • In 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? Test of Proportions User defined parameters Number Defective Group #1 (x1) Size of Sample #1 (n1) 55 8500 Number Defective Group #2 (x2) Size of Sample #2 (n2) 52 9500 Results Proportion Sample #1 (p1) 0.00647 Proportion Sample #2 (p2) p-value 0.00547 0.38506 SPC XL is Copyright (C) 1999 Digital Computations, Inc. and Air Academy Associates, LLC.

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 Final Decision: Jig. • 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 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 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 Sometimes loaders would allow The clip arms to twist when loading
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 Note the Yellow Color at top Clip used to 65 size lenses. Clip for CR, note the blue color at the top
Poly Clip • This is a Poly Clip • Note there is no color at the top of the clip.
5S / Visual Controls Team • Team Members: – Sally – Ida – Justino
5S, Visual Controls • • • • Action items list Before and After pictures 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.

Incoming Area Before 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 SOPs covered by all the WIP! Before: Small area to work, items for process have no clear home
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 A limit of 6 trays are to be at each of the 2 stations. 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
Tint Area - Before Before Picture No clear direction of flow, too much stuff, disorganized stuff on the floor, no clear SOPs.
Tint Area After
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.
Misc. Stuff Before Before Picture Inconsistency in where items are placed. Need 5S!
Load Work Station at Shift Start Before Before Picture Two Different Work Stations Load Area 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.
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 Before Picture Methanol container is to the upper left and operator is right handed, this increases the stretch. This work station looks different from others. Need 5S and standardized work stations.
Load Station Before and After This workstation looks different from others. Need 5S and standardized stations. Before Picture Jig is not used in this work station 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 rejects Before Picture After Picture No 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
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 Area, making a place for everything. 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 lenses SOPs 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 layout
Set up Kanbans for all workflow Empty trays Poly CR 39 Set up Kanban of 6 trays for Grind to Multicoat job sorting Set up Kanban of 3 trays from Job sorting to loading Set up a “Pick me Next” identifier to preserve FIFO workflow
New 1-page photo-rich SOPs
