Processes should be
optimized across the
entire life cycle, in
order to achieve the
best Lean and Six
Sigma (LSS) and
environmental benefits

What is sustainability?
• Meeting the needs of the present without compromising the
ability of future generations to meet their own needs
• Triple Bottom Line

Triple Bottom Line
• Profit – price listed on the item or the shelf, very clear
• People – nutritional value, calories/fat, cruelty-free, Fair Trade
• Planet– Local sources (low food miles), most only use words
(organic, GMO-free, no additives/coloring)

Financial reasons for sustainability
• 7 areas of financial benefit for companies
1. Increased revenue
2. Reduced energy expenses
3. Reduced waste expenses
4. Reduced materials and water expenses
5. Increased employee productivity
6. Reduced employee attrition expenses
7. Avoided risk to profit

Lean ElectronicsSM at Rockwell Collins
• Started in 1998
• Heavy on Lean tools
initially
• Incorporated Six Sigma
tools in 2007
• Umbrella over all
improvement programs

7 Forms of Waste
Waste Type
Overproduction
Environmental Impacts
•
•
•
Inventory
•
•
•
•
Transportation and
Excessive Motion
•
•
•
•
•
•
Defects
Over Processing
•
More energy use for transport
Emissions from transport
More space required for WIP movement, increasing lighting, heating, and cooling demand and energy
consumption
More packaging required to protect components during movement
Damage and spills during transport
Transportation of hazardous materials requires special shipping and packaging to prevent risk during
accidents
•
•
More space required for rework and repair, increasing energy use for heating, cooling, and lighting
•
More parts and raw materials consumed per unit of production
Unnecessary processing increases wastes, energy use, and emissions
•

More packaging to store work-in-process
Waste from deterioration or damage to stored WIP
More materials needed to replace damaged WIP
More energy used to heat, cool, and light inventory space
Raw materials consumed in making defective products
Defective components require recycling or disposal
•
Waiting
More raw materials consumed in making the unneeded products
Extra products may spoil or become obsolete requiring disposal
Extra hazardous materials used result in extra emissions, waste disposal, worker exposure, etc.
Potential material spoilage or component damage causing waste
Wasted energy from heating, cooling, and lighting during production downtime

Why can’t LSS address environmental issues?
• Improvement opportunities may be found outside of
normal working hours and areas
• “Cost of doing business,” not viewed as opportunity
•
Small impact at process level
• Costs and impacts can be blanketed across many areas,
hard to isolate data to biggest users
• Environmental and human health risks are often not
explicitly considered in business decisions
• Side benefits of efforts not anticipated or factored in
•
Take-back, talent acquisition, employee engagement

Lean Event Format (ES&H)
• Four primary “Go and See” sessions (can vary by
facility)
1. Off shift
2. Start-up
3. Working time (w/breaks)
4. Shut down/Transfer
• Break into appropriate groups and review defined
area
• Need mix of process and technical experts, fresh set
of eyes, and different levels of organization

ES&H and Facilities
ES&H
Facilities
• “Bottoms Up” with
People
– Turn off equipment
– Recycling and
composting
– Hazardous waste
processes
– Water conservation
– Air leak prevention
• “Top Down” with
Infrastructure
– Renewable Energy
– Efficiency Upgrades
– Green Cafeteria
– Electric Charging
Station
– LEED buildings
– Showers for bikers
Approach sustainability from both directions

Event Checklist
• Useful when ES&H or Facilities personnel cannot attend event
Physical Environment
As a result of the Lean event, will there be:
Unk
Yes
No
Any changes to the locations where either maintenance work or use of hazardous
chemical/material will occur?
Any changes to your personnel’s work zone assignments?
Any new equipment or modifications to existing equipment, or movement of existing
equipment that has the potential to produce air or water emissions (e.g., rinse
equipment/operations, cleaning tank, heating ovens)?
Any changes to the facility (e.g., vents, stacks, floor drains, oil/water separators)?
Any changes in the location(s) of the current flammable storage locker/areas?
Any new confined space entry activities or procedures (e.g., personnel entering fuel tanks
for cleaning)?

Event Checklist (cont’d)
Material/Chemical Use and Storage
As a result of the Lean event, will there be:
Unk
Yes
No
Unk
Yes
No
Any changes to the type or volume of materials issued to personnel and/or used?
This includes the introduction of new chemicals, elimination of chemicals, etc.
Any changes to the chemical introduction or issuance procedure for chemicals/materials
containing hazardous materials?
Any changes in the volume of chemicals/materials stored?
Any flammable materials that are not returned to the storage cabinets at the end of each
shift?
Waste Management
As a result of the Lean event, will there be:
Any change(s) to the waste profiles for wastes stored at any initial accumulation points?
Any change(s) to the location or number of initial waste accumulation points?
Any change(s) to the volume of waste(s) that require disposal (i.e., wastewater,
hazardous or solid waste) or to the volume of material that will be recycled or reused?

Integrating Sustainability into Lean and Six Sigma
Strategy
 Focus improvement efforts specifically on social and
environmental metrics
 Relate environmental and social issues to core business
needs and priorities (money, risk, reputation, etc)
 All process improvements naturally reduce impact on the
environment, now start capturing the benefits!
 Share this presentation with Facilities, ES&H and LSS
personnel
Tools




Add Earth as a customer on your SIPOC
Add environmental usage and costs to data boxes on VSM
Add environmental impacts to 7 forms of waste definitions
Integrate environmental checklists into event templates
