Do not like to see things

cramped up’

> Lima Ashar

The onus of sustaining

improvement lies with an

individual

At Organization level the

responsibility is shared equally

by all stakeholders of “5S”

All 5S initiatives should have

a direct measurable

financial focus eg

• Quality (Rework , Sorting

: Higher FPY - SOPs)

• Productivity / sq ft of floor

area (Removal of Muda)

• Power consumption

(Reduced work area and

well placed m/cs ,

material , tools)

• ROI (Higher OEE)

• No obsolesce /

deterioration of material

• doc - Kanban , FIFO

Few facts about the Second largest economy in the world

1. Children clean their schools every day for 15 minutes, which...

led to the emergence of a generation which is keen on

cleanliness.

2. Any citizen who has a dog must carry special bags to pick up

dog droppings.

3. Hygiene and eagerness to address cleanliness is part of their

ethics.

4. A hygiene worker is called "health engineer" and can

command salary of USD 5000 to 8000 per month, and a

cleaner is subjected to written and oral tests!!

5. Even though one of the richest people in the world but they

do not have servants.

6. If you go to a buffet restaurant you will notice people only eat

as much as they need without any waste. No wasteful food.

7. Rate of delayed trains is about 7 seconds ! They appreciate

the value of time, very punctual to minutes and seconds .

Emergence of :

Toyota Production System – Lean Manufacturing - 5S

No Operational Wastes Consistency Of Output

Page 11: 5S  Visual Control  7QC tools

5’S’ – A Quality Improvement tool

• Needs to be driven by none other than the CEO/Unit

head

• 1st step towards world class is identifying and

eliminating operational wastes which dent our profits

and reflect our performance negatively in front of our

customers

• A neat & orderly workplace helps in identifying wastes

• It is the first step towards implementing any new

Improvement Initiative.

• 5’S’ implementation should be associated with clear

measurable / quantitative benefits in Rs value , to be

validated by accounts department

Page 12: 5S  Visual Control  7QC tools

Why ‘5S’

• It is a quality improvement Lean tool

• New way to set standards ( as opposed to Work

study) & maintain discipline we all agree.

• Leads to greater safety & efficiency leading to

measurable financial improvements

• Gives Visibility with motivating results

• Thus ‘5S’ is known as the 1st step in journey to

Visual Control Management , LEAN , TPM &

Sorting

In normal working we tend to accumulate

1. rejections ,

2. documents and copies ,

3. in-complete work ,

4. stationery ,

5. maintenance spares ,

6. consumables etc

Sorting helps us to get rid all un-essential stuff we

keep holding for NO meaning

Page 15: 5S  Visual Control  7QC tools

How does the organization benefit

• Sorting ….

A team activity involving employees across the organization

– ( Removes un-wanted objects)

– (Reduces waste space , energy etc)

• While sorting look for

Material

– Behind and under the m/cs , racks , tables

– Rejects

– Forgotten/Obsolete material

– End pieces / rusted bearings

– Material awaiting decision for months

builds team sprit

Page 16: 5S  Visual Control  7QC tools

How does the organization benefit

• While sorting look at each object . Do we need it at all –

if not – discard / sell

• Put a red tag on all those items which are not needed

• Put a yellow tag on all those items which will be

required for production at later date and are in excess

now.

• Put all these items in Red / Yellow tag areas.

• Red tag area should be in the most prominent location

for every one to see and NOT in any corner.

For production

use at a later

date

Not required at all

( May be useful to

other departments)

Elimination Reduction

• By clearly defining Value as perceived by the customer • all Non-value added can be targeted for removal / reduction

step by step

For most operations only a

small portion of the total

time & efforts actually add

value for end customer

Page 18: 5S  Visual Control  7QC tools

What is then Waste (MUDA) ?

MUDA (Waste and Losses) Work (Value Adding) Activity +

Value Adding Activity A process step that transforms the

shape, property, characteristic or

feature of a product or service in the

direction specified by the customer

Non-Value Adding Activity

Process steps that take time,

resources, or space, but do not add

value to the product or service and

thus doesn’t add value to customer

Set-in-order “SEITON”

• Keep list of all important things like :

– Files

– Tools

– Keys and

• Ensure such lists are known and accessible to all

• A good filing system can save as much as 20% of time

spent on searching

• A world class office is expected to locate any

paper in less than a minute

• Every key should have a tag mentioning the lock or

cupboard no.

• Test the placement of everything by checking

• Assign responsibility and ownership of above

CLIT - When to do it? (Clean , Lubricate , Inspect , Tighten)

• C L I T is NOT one-time cleaning.

• C L I T has to be done repeatedly, according to a

schedule.

• It should never be done ONLY when there is free time.

(You are welcome to do it during free time ALSO).

• Production Planning must keep time aside for Initial

Cleaning.

• Ideally, keep 1 to 2 hours a week ( Min 5min each at start

and before end of each shift).

Seiso

is not just cleaning,

but also inspecting

and simple repair

and preventive

maintenance.

• Daily follow-up cleaning is necessary

to sustain this improvement.

• Working in a clean environment

enables workers to notice malfunctions

in equipment such as leaks, vibrations,

breakages, and misalignments.

• Ensure cleaning consumables/

Lubricants are replenished in time

• Ensure availability of dust bins near by

• Painting and cleaning makes it easier for

workers to notice spills or leaks quickly

the purpose of Identifying abnormalities

Page 27: 5S  Visual Control  7QC tools

Approach ( Employee Involvement )

• Train employees to collect meaningful data (free

from error of measurement)

• Develop permanent solutions using appropriate

problem solving tools

• Keep records of the process performance , update

them continuously and use them on continuous

basis.

• Train employees in the methods of SPC and other

quality improvement tools for improving quality

Incorporate Environmental and Health & safety

measures into the workplace Benefits

• ISO 14001 - International Organization for Standardization

– By reducing waste and using fewer raw materials, costs are reduced.

– Fewer costs give companies a competitive advantage.

– By managing environmental issues before a problem arises,

companies benefit from reduced liability.

– Compliance to RoHS : restriction on use of hazardous substances

– Leads to gain customer trust and improved public image. This can

be used to benefit the company from a marketing perspective.

• OHSAS 18001 - Occupational Health & Safety Advisory Services

– Identifies health hazards and evaluates risks

– Provides a safer, healthier work environment. This should help

reduce lost time due to illness and injury.

– Helps to minimize accidents.

– Fewer accidents and injuries lead to reductions in liability claims and

lower insurance premiums.

‘5S’ helps you find the Hidden factory The hidden factory is work that is done above and beyond what is required to produce a product or a service.....

Work that gets ingrained into the organization when you don’t ask "Why are we doing this, since this is not adding any value?“

"That's the way we have always done it." If you have

heard this, you probably have a hidden operation.

PokaYoke

• Japanese words "poka" (mistake) and "yoke" (prevent)

• The essential idea of poka-yoke is to design your

process so that ..

- mistakes are impossible

- the visuals/Instructions should be user-friendly and

self-explanatory giving no chance for error

• Pokayoke was originally designed for error proofing of

Quality issue , later extended to Safety for Accident

prevention ….

Page 35: 5S  Visual Control  7QC tools

Visual Control and Management

is one of the most important tools of Lean Manufacturing ..

to steer your organization to world class levels thru’

1. error proofing of processes

2. transparency in management

3. building a culture of team work leading to

4. robust monitoring mechanism

- VCM works on the principle of increasing efficiency and

effectiveness by deliberately making things visible.

- When things are visible, they are kept in conscious mind.

- It also ensures that everyone has a common viewpoint of

what is being displayed.

Page 36: 5S  Visual Control  7QC tools

Two basic applications of

Visual controls : .......

1. To convey Information

A visual display relates information and data to employees

in the area.

For example, charts showing a graphic depicting a certain type of quality

issue or the prorata (Expected vs Actual) production of the company

that group members should be aware of.

2. To provide Instructions

A visual to control or guide the action of the group

members.

Examples of controls are readily apparent in society: Stop signs, Parking

signs, No smoking signs, Road crossing etc

Some common Industry examples : Safety Instructions , SOP,

KANBAN , SPC charts , Identification boards of different

workplaces etc

1. displays and 2. controls

Page 37: 5S  Visual Control  7QC tools

• The purpose behind implementing Visual controls is to

expose abnormalities in the process that end up costing

the company money or create waste.

• When visual control is able to help employees recognize

these abnormalities action can be taken to correct the

problems,

– reduce rejections,

– reduce possible waste,

– reduce manufacturing costs

– shorten production lead time and thus

– keep the delivery due dates, reduce inventory,

– ensure a safe and comfortable working environment, and

– increase the company's profit.

• Customers are the ultimate beneficiaries of such efficiency

when they consistently receive a high quality product

Page 39: 5S  Visual Control  7QC tools

Conventional vs Visual Communication

• In Conventional communication the information is

centralized and transmitted thru hierarchical channels

• In Visual communication one creates an information

and organizes the access to employees on agreed

objectives

like Quality , Productivity , Work Instructions etc

• The visuals themselves speak

Page 40: 5S  Visual Control  7QC tools

Workmen participation

• With active involvement of workmen the visual

communication gains more importance

• Commitments and results are displayed on on-going basis

with focus on

> Quality

> Production schedule / adherence

> Inspection Instructions

> Maintenance schedule

> Performance indicators

> Group’s accomplishments

– thru charts , graphs , photographs etc

• The displays should generally face the passage-way or in

break-out area for maximum accessibility to all.

Page 41: 5S  Visual Control  7QC tools

How should Visual Workplace be ?

1. Spotlessly clean work areas

2. Living green plants

3. Clean rest areas

4. Proper identification of all items and activities

5. Production charts near work places

6. Boards to record problems

7. Instruction sheets with colored diagrams

8. Autonomy to workmen in creating SOPs

9. Supervisor need not be intermediary between

Engineering and workmen

10. No distortion between ‘official version’ and “actually used” versions of SOPs

Page 42: 5S  Visual Control  7QC tools

Knowledge dissipation 3 levels .......

• With Individuals ( ie left to each operator)

– Possibility of inconsistent quality as individuals purse

own process steps

• Centralized ( Authority with one Single dept )

– Production units lose the ability to pursue initiatives

and administrative departments gain this authority

• Public Knowledge ( across the entire work place )

– Synergy is created by taking Knowledge of

everyone, leading to stronger organization

– Procedures are created jointly , leading to ownership

– SOPs are displayed at every work station

– Organization transforms in to visual data base.

Page 43: 5S  Visual Control  7QC tools

Gemba Place where you create value for your customers

• Place where it actually happens ( Place of action)

• Gemba refers to the place where value is created; in

manufacturing the gemba is the factory floor.

• It can be any "site" such as a construction site, sales floor

or where the service provider interacts directly with the

customer.

• In 5’S’ , the idea of gemba is that the problems are visible,

and the best improvement ideas will come from going to

the gemba.

• Solutions designed away may not get acceptability

• Rather than hear or read , visit Gemba , experience the

situation FIRST hand -

• ( doctor : D Patient : Ch)

Also means “reality” or even truth

Page 44: 5S  Visual Control  7QC tools

Participative Management

• Manufacturing quality products ( consistent quality) is

possible only if workmen rigorously abide by operating

standards

• The quality of a given procedure is like the overall

harmony of an orchestra

• Production team should be involved in developing the

SOPs

• Every improvement should get updated in the SOP

• The frequency of these updates is the best

indicator of workers involvement

Page 45: 5S  Visual Control  7QC tools

Making of SOPs 1. Standard documents are the concern of Offices and not of

shop floor

2. Standards are created to last

Visual Organization reverses these misgivings

– A good standard constantly evolves

– Besides defining methods , the SOPs are meant to

inspire improvements eg • 150d centigrade ,2M instead of 100d centigrade , 4M

• 4pcs trimming instead of 2 at a time

– Displaying SOPs is a way of acknowledging the

accomplishments and responsibility of those who

created it.

– Visibility of standards leads to constant questioning of

standards leading to creativity & motivation

– Results in better ownership

Visual communication journey

1. Building a consensus

on achievable targets to meet customer needs ,

displaying the same with

a monitoring mechanism

2. Defining priority objectives

Should be acceptable to everyone

Minimum figures which need to be achieved

Objectives must be realistic , must be attainable wrt

available resources

3. Decentralizing the decision-making system

4. Creating visual schedules

Page 48: 5S  Visual Control  7QC tools

Make Progresses Visible Selecting Indicators

• If production unit’s primary role – Production nos. are visible , the secondary role – producing improvement should also be visible, eg

– Reliability of m/c , A P Q

– Period of operation w/o breakdown

– Inventory

– Lead time

– Tool c/o time

– % rejection

– No of machines monitored with SPC

– No of pokayoke

– Training skills

– Work accidents

– Safety audits

Page 49: 5S  Visual Control  7QC tools

The Seven QC tools

1. Check Sheets

2. Flow chart

3. Graphs

4. Pareto charts

5. Histograms

6. Cause and effect diagrams

7. Control Charts

Identifying

Prioritizing

Analyzing

Communicating

These tools are divided in to 4 broad categories

Page 50: 5S  Visual Control  7QC tools

Check sheets • Check sheets are ‘forms’ that systematically collect data.

• They provide structure to collect data and organize/stratify the same for analysis

• The checklist forms a base to project facts with data

• This data is then used to construct

– Histogram ,

– Pareto charts ,

– Control charts etc.

• Types of Check lists :

1. Tally check sheet

2. Defect -location check sheet

3. Defect -cause check sheet

Page 51: 5S  Visual Control  7QC tools

Bar Charts as Histograms

• When used to represent Variable data are called

Histograms

– Shows the different measures of centrality (

Mean , median , mode)

• Each bar represents a uniform interval (bin

size) of the data , and

– Bar charts are used to represent Attribute data

Page 52: 5S  Visual Control  7QC tools

Control chart as Visual aid

• Adding SPC to this data enhances visibility by allowing

for action to be taken before a process becomes out of

control.

• Knowledge of Six Sigma techniques will help in de-

coding the SPC data

– VOC vs VOP

– Process capability

– Process Sigma

Page 53: 5S  Visual Control  7QC tools

Control Chart

• It’s a type of Run chart with control limits

• Why Control charts

– It shows nature of variation in the process over time

– Helps in detecting changes in the process

– Helps in controlling the process

Page 54: 5S  Visual Control  7QC tools

Uses of Control charts

1. Monitor the process . Detect changes over a period of

time.

– The moment the process tends to go out of control

, assignable causes are found and problem is

plugged

– Continued control ensures quicker detection and

corrective action

2. As the variability is predictable , it helps in proper

estimation of output

3. Once the process is under control , efforts are put to

reduce variability

Page 55: 5S  Visual Control  7QC tools

Visual Control

• Any activity is a process.

• A process is a series of activities or steps used to

transform input(s) into output(s)

• Every process has customer and supplier

• Everyone in an organization serves a customer

• The objective of Visual control is to ensure

Individuals or groups “Do it right the first time”

• Helps to build a feedback loop into every process

so a to reduce gaps between customer’s

expectations and supplier output.

Page 56: 5S  Visual Control  7QC tools

Types of Data

Subjective based on experience ,

opinions or observations

• Used for making

personal decisions

Like :

- What to wear

- What to eat etc

• Generally , go wrong if

used for managerial

decisions

Attribute

Countable or

discrete

• Yes / No

• Go / NoGo

• Good / Bad

Tea taste

Variable

Measurable

Continuous

• Height

• Weight

• Dimension

• Temperature

Objective data

Page 57: 5S  Visual Control  7QC tools

Uses of Control charts

1. Monitor the process .

2. Detect changes over a period of time.

– The moment the process tends to go out of control , assignable causes are found and problem is plugged !!

- Continued control ensures quicker detection and corrective action

2. As the variability is predictable , it helps in proper estimation of output

3. Once the process is under control , efforts are put to reduce variability

• Let us now try to understand application of different Control charts to monitor and improve the processes

Page 58: 5S  Visual Control  7QC tools

Variable Control Charts

• Variable Control charts are used to monitor measurable

quality characteristics of a process eg Temperature ,

dimension , weight , viscosity etc

• Variable charts can monitor only one quality

characteristic at a time .

• For more than one characteristic, a chart for each

characteristic needs to be created

• Variable Control charts help to monitor both process

mean X and process variability R or σ

• Hence it becomes necessary to use minimum 2 control

charts to study the process. Ie

– Range or Std Deviation

– Process mean , with UCL & LCL

Control Charts for Attributes

• Whenever it is difficult to take numerical measurement

the quality is judged either conforming / non-

conforming - Defectives based on attributes( Np and

p charts) :

– Leaks / does not leak , No. of counts scratches ,

holes , dents etc .

• Attribute data can have two values , such as pass/fail

present/absent etc ie data which can be counted.

• It can also be no. of non-conformities (defects) that

appear on a unit ( No of dents , a/c opening form ,

scratches , holes etc) : C & U charts :

• The inspection doesn’t require spl trained people as no

measurements are involved .

Example : Vendor Performance Dashboard

• Real-time information is put on supplier dashboard giving internal and external supplier metrics and Key Performance Indicators

• The Vendors are judged on their performance the way we judge the performance of our employees.

• The goal is to develop a world-class supplier quality system

• Steps to build a world class Vendor base

– Standardized Vendor audit process

– Building Vendor risk management scorecard

• It helps to actually know which suppliers are more risk-prone and therefore require more attention v/s auditing suppliers arbitrarily or because a certain amount of time has passed.

Don’t let your charts look like Swiss army knife..

• It should typically be a paper chart

or dry erase white board that is

positioned at the process.

• It should be low-tech and reflect

the line, cell or team name, output

requirements ( assemblies,

invoices, etc.) and

• fields to record the problem or

reason for any hourly plan vs.

actual deltas as well as

• a sign-off by lean leader(s) as

proof of review.

The chart should typically be plan vs. actual chart – also

known as the output analysis board (or chart), day-by-the-hour

chart, etc.

Precaution

Page 67: 5S  Visual Control  7QC tools

1. Introduced without training

2. Not worker-managed

3. Not self-explaining

4. Not visual/visible. not very visual due to tiny size, lack of

color, poor location, etc.

5. Too hard or complicated to use

6. Obsolete. Process is changed and the visual is still old

7. Lack of discipline. Lack of level of discipline to maintain

visual controls.

8. Lack of transparency of purpose

9. Lack of faith. People give up when they determine that no

one reliably responds to the abnormal conditions.
