How to look for waste: Motion mindExample: Simple Mixing operation
All operations are composed by 3 elements such as 1. Value adding motion, 2. Auxiliary motion, 3. Waste motion
1. Reach for the Ingredient & Spoon Auxiliary motion
2. As it is too far, arm is lengthened further
3. The ingredient is brought close to the Mixer

ZONESStep 1 - SEIRI
ZONES
• The company to be divided into several small zones to include every inch of space in the company (incl Work area, office area, Security cabin, canteen, toilets, garden, srapyard, etc)
• Each zone to have a zonal coordinator
• Take ‘Fixed Point Photographs’ (FPP) to record ‘ Before’ conditions• Take Fixed Point Photographs (FPP) to record Before conditions progressively (Week 1-2-3-4…..), zonewise
• ‘Worst Point photography’ (WPP) can be taken by the highest authority p g p y ( ) y g yduring his factory rounds/ audits and presented to the zonal co-ordinator for necessary actions (i.e for number of zones clubbed together)

Red Tag Holding Area
R d t H ldiRed tag Holding areaThis is an area set aside for use in storing red tagged items that need further evaluation
(Why- It gives you a safety net between first questioning whether something is needed, and actually getting rid of it)
Types of Red Tag Holding AreaLocal Red Tag area – The Dept / Zones / Area can have individual red tag area to avoid mix up of items with other areasC t l R d T A L t it ld b b tt t h t l d t f di lCentral Red Tag Area – Later it would be better to have a central red tag area for disposal

Step 1 - SEIRI
Criteria for Red Tag
• Every person asks to all the items around his / her workplace
Is this item needed ?
If it is needed, is it needed in this quantity?
If it i d d i it i d f tl ? If it is needed, is it required very frequently?
If Answer is “NO”
REMOVE FROM WORKPLACE

RED TAGGING
The best way to carry out red-tagging is to do the whole target area quickly
RED TAGGING SHOULD BE A SHORT AND POWERFUL EVENT

Step 1 - SEIRI
Review the Red Tagged Items
• The review team would consist of senior members who can take d i i di l it t i l d l b i itdecisions on disposal, it must include personal buying new items
First a “purchase ban” on all items red tagged till inventory lasts
Review the items accordingly
Keep the item where it isp Move the items to a new location Store the item away from the work area Hold the item in the local red tag area for evaluation Disposal of the item Disposal of the item

Step 2 - SEITON
Definition
Seiton means that
You arrange needed items so that they are easy to to use and label them so that anyone can find them and put them away
How? A Place for everything and Everything in Place P fi d Q titi i P fi d l ti Pre-fixed Quantities in Pre-fixed locations

Step 2 - SEITON
Why ?
• SEITON is important because it helps eliminate many kinds of waste in the p p yworkplace Motion Waste – Person sent to find cart searched full factory Searching Waste – No one can find the key to the tool cabinetg y Waste of Human Energy – Frustrated worker gives up searching for
template after two hours Waste of Excess Inventory – Desk drawers are full of papers and Waste of Excess Inventory Desk drawers are full of papers and
stationary supplies Waste of defective products – Items not kept back in the same location
so worker picks up wrong piece for assembly Waste of unsafe condition – Boxes of material kept in the walkway,
causing someone to trip and get injured

Deciding App op iate locationStep 2 - SEITON
Deciding Appropriate locationPrinciples of Storing Jigs, tools, Dies for waste elimination
1. Locate the items in the workplace according to their frequency of use Place frequently used items near the place of use Store infrequently used items away from the place of useStore infrequently used items away from the place of use
2. Store items together if used together, and in sequence if used in sequence.3. Devise a “Just let go” arrangement for tools (eg. suspend the tools)4 Make storage space larger than the item so that easy to put back4. Make storage space larger than the item so that easy to put back5. Eliminate the variety of jig, tools an dies by creating multi function jigs, tools and
dies.6 Store tools according to function or product based on the type of usage6. Store tools according to function or product based on the type of usage

Identifying locationIdentifying locationColour coding Strategy
• Colour coding strategy can be use to indicate which items is used for which part Examplesp Different colours can be allotted to different oils and the oil bath to be
marked the colour of the type of oil to be used If certain items are used for making the same part then the items can be
colour coded the same colour and kept in a location having the same colour.
Inventory levels can be colour coded to indicate the critical, designed, reorder and excess levelsreorder and excess levels

Identifying locationOutlining Strategy
• Outlining is a method to show which jigs and tools are stored where.
• Outlining means drawing outlines of jigs and tools in their proper locations

Decide who is responsible for 3 S activities E t k tl h t th ibl f d i Everyone must know exactly what they are responsible for doing
and exactly when, where and how to do it. 5S maps with responsibilities and frequency 3S cleaning instructions on area of 3S 3S cleaning instructions on area of 3S
Integrate 3S duties into regular work duties Visual 5S (Abnormal conditions are seen at a glance) Five minute 5S (Efficient and quick solutions are given for doing
cleaning)
Check on 3S maintenance level AUDIT

Step 4- SEIKETSUPrevent from putting things back (Contd.)
Suspension Suspend the tools with a spring balancer. Once the use is over the
operator “just let’s go” and the tool goes back to its desired position
IncorporationHere create a flow of goods such that jigs, tools and measuring instruments are smoothly integrated into the
process and hence stored in the place of usageprocess and hence stored in the place of usage
• Example – fix a measuring gauge on the conveyor, eliminating the need of picking up the gauge and measuring and putting the gauge back
