Introduction

Objective:

The objective of 5S is to create a

company culture which perpetuates a

neat, clean, efficient workplace

are critical as a starting point in the development of continuous

improvement initiatives and activities

Red Tag Strategy

Red Tag Strategy

Step 1

Initiate First Round of Red Tagging

– Select the Kaizen team

– Members should be from the area as well as from

“outside”

– Appoint a team leader

Step 2

Identify Red Tag Targets

– Inventory, equipment, supplies, tooling, space

– Office areas are not exempt from red tagging

Step 3

Define Red Tag Criteria

– Determine what criteria will be used to distinguish a

needed item from an unneeded item

– Example: Save only the items needed to make next

week’s or next month’s production schedule

July 2008

25

Red Tag Strategy

Red Tag Strategy

Step 4

Conduct Red Tag Session

– Explain Red Tag criteria to teams

– Ensure a good cross-section of people tagging items to

prevent “I might need that”

– Red Tag entire area as rapidly as possible

– Move all tagged items to a “red tag area” nearby (and

clearly defined as such)

– Post red tag “receipts” on a flip chart board in the cell

Step 5

Advertisement

Evaluate the Red Tag Targets

– Review material which has been red tagged

– Dispose of truly unnecessary inventory, equipment and

other items – THROW IT OUT – FOR GOOD!!!

– Teams may retain material which has been mistakenly red

tagged if they can justify it to the team and organize it…

– Discard any material which is still tagged after a pre-

determined time (One week – maximum one month?)

– All Red Tags must be completed and returned

Helpful Hints

• Record information about all tags used on a Red Tag Log so

that dispositioning can be tracked easily (sample at end of

manual)

• Make sure everybody understands what is to be red tagged and

why

• Discourage people from being defensive

Be fair – all areas get tagged!

• Don’t red tag people

• Don’t compromise; If in doubt, throw it out!

• Necessary items can be tagged if improvements are known or

suggested

• Do not put multiple tags on any one object

– Focus on getting items as close to point of use as possible

Prepare Locations

– Decide on storage method to be used

– Remember function and 5S guidelines

– Kaizen storage methods for ease of use

– Evaluate all containers – minimize size

Step 3

Indicate Locations

– Make signboards and hang in proper locations to indicate where

items belong

– See sample pages for types of signboards

Strategy

Step 4

Indicate Item Names

– Make signboards which clearly show

• The name of the item and any identification numbers

• The address of its storage location

Step 5

Indicate Amounts

– Signs should show how many pieces of a particular item should

be on hand

– Each indicator should define at least the minimum and

maximum amounts

Shadow Boards

Shadow Boards

Purpose:

Shadow boards are used to indicate proper location of tools, gages,

and other items needed for a job.

Outline

• These are the simplest form of shadow graphs, often simply boards

conveniently mounted for accessibility to the tools, with outlines of the tools

painted on the board.

Relief

• Another variation of shadow board

• Relief boards have contours milled into the wood or plastic

• Providing the shape recognition of an outline, with added security for the

tools

• Best if mounted at an angle to prevent placing anything else there

Use yellow for tools & standard items, and blue for gauges / quality stations

Shadow Marking and Painting

Shadow Marking and Painting

Floor markings are a variation of shadow graphing, again used to indicate

proper location of inventory, forklifts, machines, furniture, etc.

Two principles methods:

– Vinyl tape

• 3M 471 or equivalent tape for floors and other markings

• Available in the 5 primary colors

– Paint

• Avoid paint striping unless you’re sure – hard to change!

• Paint signboard, shelves, racks, other items the right color

• All machines should be painted very light – preferably white - colors

Consider: Durability versus Flexibility

Choose where you mark carefully! Don’t just trace around trash!

Sustain

• Use the 5S Patrol Check Sheet to evaluate areas

– Work team should do this weekly

– Rotate team members so everyone get a turn to audit the area

– Supervisors should review the audit once done and point out any

areas of improvement

– Plant management should check each area at least monthly

– Identified problems must be recorded on a kaizen newspaper to be

fixed, or fixed right away

• Use visual management to show 5S results

– Post the current 5S audit sheet on the cell visual board

– Post the appropriate 5S wheel sections to reflect area scores

• Be proactive - focus on continuous improvement
