Going LeanGoing LeanAn Introduction to Lean

Principles

Objectives

• Understand what lean manufacturing is

• Know the difference between value and waste in our process

• Recognize the 8 types of waste• Become familiar with the lean

tools

Agenda

• Introduce Lean Manufacturing

• Define waste and value

• Communicate the types of waste

• Introduce basic “lean tools”

• Agree on a path forward

What is Lean Manufacturing?

• The optimization of value in our process so that we have the ability to make exactly what is needed, when it is needed and in the quantity it is needed by our customer

• The relentless identification and elimination of waste from our process so that we can flow at the rate of customer demand

How Will Lean Help Us?

• Reduce Lead Time to our customers by eliminating waste from our system

• Reduce frustrations by removing barriers to doing our jobs

• Encourage everyone to get involved in improving the process

• Increased customer satisfaction• Optimally utilize resources while

meeting our customer’s needs

What is Value?

• A measurement of the worth of a product, or service, by a customer based on it’s usefulness in satisfying a customer need

• An activity, process or operation that changes the product from one form to another in order to get it closer to the customer’s specifications

• It is something that the customer is willing to pay for

What is Waste?

• Any activity that adds costs or time but does not add value

• Consuming more resources (time, money, space, etc) than are necessary to produce the goods, or services, that the customer wants

• Pure Waste: Actions that could be stopped without effecting the customer

• Incidental Waste: Actions that need to be done based on how the current system operates but do not add value

The 8 Types of Waste

OverproductionInventoryTransportationMotion (Operations)ProcessingDefects / QualityWaitingPeople’s Skills

Overproduction

• Common causes:– Producing more than is required to

make up for yield loss– Scheduling production to forecasted

demand– Long changeovers or avoiding

changeovers lead to large lot production

• Supplying the process with more than is needed to meet order requirements, sooner and faster than it is needed, causes almost all other types of waste

• This is the worst waste of all, because it helps cause all the others

Inventory

• Common causes:– Overproduction– Poor equipment layout– Long changeover times– Defective, or questionable, parts– Mismatched production speeds

• Requires people, equipment and space to count, transport, store and maintain it

• If we do not get orders the material will become obsolete, and be thrown away

• Inventory is often used to help hide other wastes

Transportation

• Common causes:– Extra Inventory

– Retention points before and after operations

– Excessive distance between operations (layout)

– Single skill focused operations

• Double or triple handling, moving in and out of storage areas and warehouses

• Material can get damaged if it’s moved too much• It adds no value and is often used to get the extra

inventory out of the way

Motion (Operators)

• Common causes:– Poor workstation layout– Isolated operations– Shared tools– Fatigue– Workstation congestion

• Walking without working (away from workstation) • Searching for tools, materials or information• Reaching, bending or unnecessary motion due to

poor housekeeping or workplace layout• Process is not designed with employees in mind

Processing

• Common causes:– Lack of standard work or

processes– Equipment over designed– Process not updated with

technology changes– Lack of effective problem solving

• Doing more than is necessary to produce an effectively functioning product

• Extra setup steps, over-specification of the process, extra processing steps

Defects / Quality

• Common causes:– Emphasis on downstream

inspection; questionable material passed on

– Lack of standard work

– Material handling (transportation)

– Process design/equipment

• Defective or scrap materials• Cost of inspecting defects• Responding to customer complaints• Rework or re-inspection of questionable materials

Waiting

• Common causes:– Mismatched production rates

– Poor layout

– Machine breakdowns• Ours or upstream

– Insufficiently staffed

• Operator waiting for machines to run or cycle• Machine waiting for operator• Waiting for parts, instructions, approval,

information, maintenance, decisions…

People’s Skills

• Common causes:– Management does not involve

employees in problem solving– Narrowly defined jobs and

expectations– Old school management,

worker relationships

• Employees are seen as a source of labor only, not seen as true process experts

• People are told what to do, and asked not to think• Employees are not involved in finding solutions,

opportunities to improve our process are missed

Waste – the simpler part…

5 Lean Principles make up the 5 Lean Principles make up the Lean Strategy for Our CellLean Strategy for Our Cell

1. Specify value

2. Map the flow of value

3. Make value flow

4. Pull from the customer

5. Seek perfection

1. Specify Value for Our Customer(s)

• Value added steps lead to a transformation of the material from one form to another which gets the product closer to the customer’s specifications

• Providing the right product, at the right time, in the right quantity, at the right quality, at the right price, in the right place in accordance to the customers requirements

A value stream is all of the value-adding activity AND all of the non-value adding activity (pure waste and incidental waste) required to provide a product/service to a customer

2. Map the Flow of Value in Our Cell
