Lean Design, Lean Manufacturing, Lean Inventory/Supply Management – A Sustainability “Trifecta”

Source (Popular Mechanics)

You’d have to be living in a mountain cave or vacationing on the south coast of France to not know that world stock markets are being whipped around these past two weeks.  The USA Today has attributed what’s been happening in the markets here in the U.S. along seven key elements, all of which is related more to external factors such as the European money woes, general investor fear and lack of policy direction from the federal government.

The general market fear and scurrying for shelter reminds me that when hikers are caught in a sudden storm, they often seek shelter in a “lean-to” or other protective cover until the skies clear.

I thought that in light of the economic body slamming that has been going on this past week, it’s worth reflecting on some efficiency-based ways that  businesses can use to overcome (or at least buffer) some of the external factors that are causing such economic uncertainty.  Like the hikers seeking shelter from the storm, there are some “lean-to”-like steps that company’s can take to exert some control and influence — and it all relates to a leaner, greener, smarter enterprise.

The Lean and Green Enterprise

Last winter I wrote about how importance a “lean and green” enterprise was in establishing a smarter, leadership position in a rapidly changing global marketplace.  I noted then that a 2009 study suggested that “lean companies are embracing green objectives and transcending to green manufacturing as a natural extension of their culture of continuous waste reduction, integral to world class Lean programs.”  Lean was more rapidly accomplished with a dedicated corporate commitment to continual improvement, and incorporating ‘triple top line’ strategies to account for environmental, social and financial capital.  I also argued by looking deep into an organizations value chain (upstream suppliers, operations and end of life product opportunities) with a ‘green’ or environmental lens, manufacturers can eliminate even more waste in the manufacturing process, and realize some potentially dramatic savings

So I was reminded this past week that Lean in design, Lean in manufacturing, and Lean in inventory can individually or collectively be key success factors in managing waste in all its many forms.  Collectively, this can have a measurably positive effect on a company’s financial, and hence, business performance.  A couple of recent articles touched on this topic this week while you were watching your 401(K) equity or stock value tank.   But first let’s touch on Lean Design.

Lean Design

I came across an older but very relevant article written in the aftermath of the Internet stock crash in the early 2000’s.  The article described product development as involving “two kinds of waste: that associated with the process of creating a new design (e.g., wasted time, resources, development money), and waste that is embodied in the design itself (e.g., excessive complexity, poor manufacturing process compatibility, many unique and custom parts).”  The article cautioned that because the design process is the cradle of creative thinking, designers needed to carefully watch what they “lean out” or risk cutting off the creative process to reduce waste.  What has happened in the ensuing years has been an incredible emphasis on “green design” that focuses on full product life cycle value, such that “end of life management” considerations have taken on a more relevant and embedded nature in manufacturing.

A Lean Manufacturer Can be a Sustainable Manufacturer

In yet another recent article by manufacturing consultant Tim McMahon (@TimALeanJourney), he notes that “Lean manufacturing practices and sustainability are conceptually similar in that both seek to maximize organizational efficiency. Where they differ is in where the boundaries are drawn, and in how waste is defined”.  He notes, as I have in my past posts, that Lean manufacturing practices, which are at the very core of sustainability, save time and money — an absolutely necessity in today’s competitive global marketplace.

The key areas to control manufacturing waste and resource use during the design and manufacturing cycle, can be broken down  and managed for waste management and efficiency in the following five ways:

Reduce Direct Material Cost – Can be achieved by use of common parts, common raw materials, parts-count reduction, design simplification, reduction   of scrap and quality defects, elimination of batch processes, etc.

Reduce Direct Labor Cost – Can be accomplished through design simplification, design for lean manufacture and assembly, parts count reduction, matching product tolerances to process capabilities, standardizing processes, etc.

Reduce Operational Overhead –  Efficiencies can be captured by minimizing impact on factory layout, capture cross-product-line synergies (e.g. a modular design/ mass-customization strategy), improve utilization of shared capital equipment, etc.

Minimize Non-Recurring Design Cost – Planners and practitioners should focus on platform design strategies to achieve efficiencies, including: parts standardization, lean QFD/voice-of-the-customer, Six-Sigma Methods, Design of Experiment, Value Engineering, Production Preparation (3P) Process, etc.

Minimize Product-Specific Capital Investment through: Production Preparation (3P) Process, matching product tolerances to process capabilities, Value Engineering / design simplification, design for one-piece flow, standardization of parts.

Can a Lean Inventory Management Drive Sustainable Resource Consumption?

Business Colleague Julie Urlaub from Taiga Company  (@TaigaCompany) summarized a post in a recent Harvard Business Review by green sage Andrew Winston (@GreenAdvantage).  The article, Excess Inventory Wastes Carbon and Energy, Not Just Money describes how the global marketplace “ is sitting on $8 trillion worth of ‘for sale’ inventory [the U.S. maintains a quarter of that  inventory].  These idle goods not only represent a tremendous financial burden but an enormous environmental footprint ” that was generated in the manufacturing of those goods.  Mr. Winston maintains that “If we could permanently reduce the amount of product sitting idle, we’d save money, energy, and material.”  The problem is predicting and managing inventory in such fickle times.   Winston went on about new predictive tools being advanced by companies that hold promise in nimbly driving inventory demand response up the supply chain.  For instance, he noted that “ using both demand sensing software and good management practices, P&G has cut 17 days and $2.1 billion out of inventory. All that production avoided saves a lot of money in manufacturing, distribution, and ongoing warehousing. It also saves a lot of carbon, material, and water.”

What Mr. Winston found shocking though (me too!) was that “even with the fastest-selling, most predictable products, the estimates are off by an average of more than 40 percent. Imagine that a CPG company believes that 1 million bottles of a fast-turning laundry detergent will sell this week. With 40 percent average error, half the time sales will actually fall between 600,000 and 1.4 million bottles. And the other half of the time sales will be even further off the mark.”  The process becomes self perpetuating and the inventory racks up along with the parallel environmental footprint, unless somehow the uncertainty can be better predicted.  While companies like to have on hand what Mr. Winston referred to as “safety stock”, I have come to know as reserve inventory driven by “just in time” ordering .  But that process was shown to have its own flaws such as when orders for goods dried up overnight in 2008 and when it came time to ramp up in early 2010, part counts were insufficient to meet the rising demand.

I really pity the supply chain demand planner, who like the weatherman is subject to the fickle nature of an unpredictable force.  Winston wrapped up his article by stating that “ reducing the inventory itself could be the greenest thing [logistics executives] can do”.  I had the chance to speak and attend the 2010 Aberdeen Supply Chain Summit where demand response planning was discussed at length and where green supply chain issues were recognized as one of many key attributes in effective supply chain management.  In such a volatile economy, its vital that companies keep inventory management in mind as a way to leverage its costs and simultaneously look toward environmental improvements that can reduce waste.

Partnering for Progress

A relatively recent pilot program in the State of Wisconsin just shows how partnering to create a lean focused sustainable manufacturing cluster can have enormous dividends.  According to a recent article in BizTimes.com, the Wisconsin Profitable Sustainability Initiative (PSI) was launched in April 2010 by the Wisconsin Department of Commerce and the Wisconsin Manufacturing Extension Partnership (WMEP). The goal according to the article is “to help small and midsize manufacturers reduce costs, gain competitive advantage and minimize environmental impacts”.  Forty-five manufacturers participated in over 87 projects evaluated. These projects focused on “evaluating and implementing a wide range of improvements, including reducing raw materials, solid waste and freight miles, optimizing processes, installing new equipment and launching new products.  The initial results show that the projects with the largest impact do not come from the traditional sustainability areas such as energy or recycling. Instead, outcomes from the initial projects suggest that transportation and operational improvements are places where manufacturers can look to find big savings, quick paybacks and significant environmental benefits.”

The program is projected to generate a five-year $54 million economic impact, including: $26.9 million in savings, $23.5 million in increased/retained sales and $3.6 million in investment.

Lean design,  Lean manufacturing, Lean inventory management – a Waste Containment and Efficiency “Trifecta”

Together, lean design,  lean manufacturing  and effective, lean inventory management offer a “trifecta” approach for industry to identify, reduce or eliminate and track waste.  Effective use of these tools cannot only drive both in how the product is designed and  produced but offers opportunities all the way up the supply chain to manage effective inventory and resource consumption. As the University of Tennessee studied concluded,  the implications of lean strategies are 1)  Lean results in green; and 2) Lean is an essential part of remaining competitive and maintaining a quality image.  Put the two together and a company can virtually be unstoppable…or a least a bit more recession-proof and “shelter from the storm”.

Can Apple Redeem Itself on Supply Chain Sustainability? Taking a Cue on Accountability from Nike’s Playbook

NOTE: Portions of this piece originally appeared as a guest column in Sustainable Business Oregon

Last week, on the way to a business meeting in downtown Portland I tuned into the local sports radio station.  Nationally syndicated sports commentator Dan Patrick (“DP”) was providing his one minute Above the Noise segment.  The focus was on if, how and when sports icons that have fallen from grace (due to an off the field indiscretion) they could ever redeem themselves in the public court of opinion.  And could they ever regain public acceptance to be ‘marketable’ commodities again.  Think player product endorsements.  Think Tiger Woods, Michael Vick, Ben Roethlisberger, Kobe Bryant, Ron Artest- well the list is WAY to lengthy to cover here, but you get the idea.  Most that have regained endorsement status (like Bryant) have either redeemed themselves through community service and on field performance, but often the public-at-large (er, consumers) just forget.  The past indiscretions have faded from the tabloids.

So I got to thinking that this sounded very familiar when it comes to companies (manufacturers and service industries in particular), and the ways in which they address sustainability matters.  I am thinking of manufacturers who have made environmentally impactful products, and willingly or knowingly conducted socially irresponsible or possibly unethical business practices that have led to public backlash.  And I thought about how some have been able to successfully “redeem” themselves and regain a positive marketplace reputation, while others never quite recovered.

Since this past week Apple was in the news, I thought DP’s radio op-ed was a perfect parallel.  According to a report issued by anti-pollution activists in China, Apple is more secretive about its supply chain than almost every other American company operating in the country. Apple came up among the laggards among 29 major electronics and IT firms in a transparency study drawn up by a coalition of China’s leading environmental groups.  The reports focused on “the openness of IT firms and their responsiveness to reports of environmental violations at suppliers”.  Though Apple is known in the industry for the secrecy it wraps around its newest product offerings, the “mystery of its supply chain is more a matter of covering up than preventing leaks”, the report stated. The report claimed that Apple’s suppliers have been involved in breaches of environmental regulation, including major waste discharge violations in recent years at several Chinese firms that are believed to be  part of Apple’s supply chain.  To be fair, Nokia, LG, SingTel, Sony and Ericsson also fared poorly in the survey, but Apple stood out in how it did not address and respond to the findings.

Apples Supplier Commitment

Of course this revelation was not the first time that Apple’s supply chain management oversight (or lack thereof) has been ‘shaken to its core’. Despite Apples Supplier Code of Conduct, it appears that they are not fully conforming to their own internal commitment and policies.  An insightful post from back in mid 2009 highlighted the series of issues that Apple has had with its supply chain, from human rights violations and pollution to lax supplier oversight and unfortunate subcontractor worker suicides.  Apple itself admitted its complacency in addressing social and environmental sustainability issues in a pragmatic but resolved manner.

Nikes Redemption Story- a Work in Progress

Apples current predicament is not unlike another company that relies on a deep contractor supply chain, whose headquarters in my backyard- Nike.  In the late 1980’s reports were starting to circulate from Indonesia and Asia concerning Nikes alleged “sweatshops”.  Over the course of the 1990’s, continued exposure of unscrupulous labor and human rights practices, combined with intensive public protests and campaigns continued to hound Nike and dragged down its reputation.

By 2001, the issue erupted and Nike was stung by reports of children as young as 10 making shoes, clothing and footballs in Pakistan and Cambodia.  Phil Knight, Nikes CEO admitted the company “blew it”. Nike, like many other companies (like Nestle, PepsiCo, Wal-Mart and other consumer products manufacturers and retailers) learned the hard way that taking liberties with “social license” to operate (especially in foreign countries) has its negative financial and reputational consequences.

That’s not to say of course that all is perfect in Niketown.  But with the corporate and supply chain infrastructure now in place to monitor, validate and continually improve supplier relations and accountability, fewer violations have occurred. Nike has continued to push open innovation and environmentally focused product design with social accountability in mind.  The Ethisphere Institute named Nike as one of the World’s Most Ethical Companies for 2010. The Institute recognizes organizations annually that “promote ethical business standards and practices by going beyond legal minimums, introducing innovative ideas benefiting the public and forcing their competitors to follow suit.”   Also, last October, Newsweek magazine took 500 of the largest publicly traded U.S. companies and produced a 2010 Green Rankings List.  Nike, was 10th on the list, and was noted for having a strong commitment to evaluating and improving the environmental footprint of its suppliers.  They also scored a 97 in the reputation category. (Apple by the way scored 65^th, with a reputation score of 71.  I guess that low score represents that missing piece in Apples iconic logo.

Stepping Up to the Plate on “Social License to Operate” and Accountability

A great research study from 2002 (from the Center for the Study of law and Society at University of California Berkeley)  highlights the steps that companies in the apparel, forest products, consumer goods, oil and energy and other highly capitalized industries have gone through to “redeem” themselves and restore brand trust.  They’ve achieved this through rigid compliance with local environmental rules, product  and environmental stewardship, verification  and proactive social engagement.

Apple needs to do the same thing and implement a proactive supplier sustainability and verification program.  As I have laid out in prior posts, companies like Nestle, Corporate Express, Danisco, Starbucks, Unilever and the apparel industry stepped up in a big way to address human rights, fair labor and sustainable development in areas in which they operate throughout the world.  So too have major electronics companies like Hewlett Packard and IBM in leveraging their supply chains in assuring that corporate sustainability performance objectives are met.   Further, in 2010 the International Organization for Standardization (ISO) unveiled its ISO 26000 Corporate Social Responsibility guidance document.  In addition, two prominent organizations, UL Environment and Green Seal unveiled and vetted two sustainability focused product (GS-C1) and organization (ULE 880) standards this past year, both of which may markedly affect supply chain environmental and social behaviors in the future.  That’s not to mention the issue of conflict minerals, which strikes deep at the cell phone manufacturing sector.  Finally, the age of openness and collaboration has arrived on the heels of Wikileaks and numerous high profile reputational back breakers.

Engaging and Leveraging the Supply Chain

The most successful greening efforts in supply chains are based on value creation through the sharing of intelligence and know-how about environmental and emerging regulatory issues and emerging technologies.  Leading edge, sustainability –minded and innovative companies have found “reciprocal value” through enhanced product differentiation, reputation management and customer loyalty.  Suppliers and customers must collaboratively strengthen each other’s performance and share cost of ownership and social license to operate.  But supply chain sustainability and corporate governance must be driven by the originating manufacturers that rely on deep tiers of suppliers and vendors for their products.

So Apple should take a cue from Nikes playbook- “Just Do It!”  This issue will not go away on a wing and a prayer.  Here’s how to get it done- right:

1)  As the 2009 post that I mentioned said, get your company on the ground and enforce your Supplier Code of Conduct – now.

2)  Open Up and reach out to external stakeholders, not just your suppliers.  Engage non-governmental organizations early and often.   Find a respected international organization or other third-party to facilitate the engagement process.   Treat communities, NGO’s and suppliers with respect.

3) Work with your supply chain and with industry peers to standardize requirements. Create or revisit the resources allocated in internal procurement networks to collaborate on environmental and social sustainability issues.

4) Construct environmental and social accountability requirements at the purchasing phase. Build environmental and social conformance criteria into supplier contract specs and incorporate sustainability and environmental staff on sourcing teams

5) Inform suppliers of corporate environmental concerns. Standardize supplier questionnaires and make sure that the Supplier Code of Conduct lands in the right hands.  Promote exchange of information and ideas by sponsoring charettes to facilitate discussions between customers and suppliers on environmental and social license issues.  Develop a supplier/vendor peer or mentoring program that promotes co-innovation on sustainability issues

6) Build environmental considerations into product design w/ suppliers. Apple already considers Design for environment (DFE) product innovation and life cycle analyses in its product design.  You’d be well served to coordinate minimization of environmental impact in the extended supply chain and work with suppliers to manage end-of-pipe environmental issues.  Give your suppliers an incentive to reduce their environmental loading associated with their products and improved worker conditions.

7) Follow up! Without adequate on-the-ground follow-through, on-going supplier engagement and long-term commitment of human and financial capital, your sustainability problems will persist.

So like sports stars, business stars can redeem themselves and their reputations.  But it first takes admitting that you have a problem before you can start down that path.  Apple has had a pretty rough year, what with CEO Steve Jobs taking medical leave, its products having persistent quality problems and its connection with negative environmental and human rights issues.  I’m hopeful that Apple and others will get the message that ol’ Ben Franklin stated so long ago but holds true today:

“It takes many good deeds to build a good reputation, and only one bad one to lose it.” -Benjamin Franklin

Until then, “I’m a PC”.

Lean, Green Manufacturing Intersects with Sustainable Supply Chain Management, Creates Value

An efficient manufacturing process is the essence of sustainability…and is by its very nature, green.  This was the gist of the business case that I posted last year and that is captured in an article published in the MIT Sloan Management Review.   MIT presents two ways of thinking:

• Old Thinking: Companies have long mistakenly thought that adopting environmentally friendly processes adds costs.
• New Thinking: Green practices like recycling, reusing and reducing waste can cut costs because they make a company more efficient.

Recalling Michael Douglas’ character “Gordon Gecko “ in the 1987 film “Wall Street” statement that “Greed is Good”, MIT Sloan’s basic message is a bit of a twist- “Green is Good”.  Manufacturing is showing with increased frequency, that companies incorporating lean practices in manufacturing, are (by design or accident) becoming more “green”.  In fact a 2009 study by a research group suggested that “lean companies are embracing green objectives and transcending to green manufacturing as a natural extension of their culture of continuous waste reduction, integral to world class Lean programs.”  This is especially true for companies that integrate a number of proven methods e.g. ISO quality and environmental management systems, to meet environmental compliance and stakeholder needs.  This is more rapidly accomplished with a dedicated corporate commitment to continual improvement, and incorporating ‘triple top line’ strategies to account for environmental, social and financial capital.

What is “Lean”?

‘Lean’ Manufacturing is a set of continuous improvement activities closely connected with the Toyota Production System (TPS) and Just-In-Time Manufacturing systems.  One emerging working definition of Lean is “The elimination of waste everywhere while adding value for customers”.  This definition is a natural fit with sustainability and the “Lean and Green” business ethic.  Lean manufacturing has demonstrated how companies have saved or avoided enormous operating and maintenance costs and significantly improved the quality of their products.

Lean manufacturing looks at manufacturing from a systems perspective, which includes a thorough evaluation of upstream and downstream process inputs and outputs.  Viewed this way, suppliers and customers play a critical role in successful lean manufacturing.  Heavy emphasis is placed on design and innovation and obtaining  input of from supply chain partners, individuals and organizations through a process called ‘value-stream mapping’ (hey that’s my blog name too- ironic?…not).

The Lean, Green and Supply Chain Intersect

As I have previously said, even without specifically targeting environmental outcomes, lean efforts have been demonstrated to yield substantial environmental benefits (pollution prevention, waste reduction and reuse opportunities etc.). However, because environmental wastes and pollution are not the primary focal points, these gains may not be maximized in the normal course of a lean initiative. This is because lean waste is by its nature not always in sync with typical environmental wastes.[1] I argue that by looking deep into your your value chain (upstream suppliers, operations and end of life product opportunities) with a ‘green’ or environmental lens, manufacturers can eliminate even more waste in the manufacturing process, and realize some potentially dramatic savings

Where ‘lean’ creates a positive view (future state) of a process without waste, ‘green’ creates an alternative view of a sustainable future for organizations that play in the global marketplace or offer a unique disruptive innovation.  Lean and green approaches to manufacturing not only leverages compliance issues but also puts companies on the path to going beyond compliance. The graphic below from the U.S. Environmental Protection Agency applies the key ‘lean waste’ types in an environmental context, and crosswalks how lean waste issues can have direct environmental impact on an organization.

Using an example set by Subaru of Indiana,the MIT study shows how there are many proofs to the axiom that prevention of pollution and continually improving efficiencies with an environmental benefit works even in lean economic times. Subaru found that:

1.      Profits come by increasing efficiency and reducing waste—but they don’t always come immediately.

2.      Management’s leadership is vital in setting goals and getting departments to cooperate.

3.      The front line workers have to be engaged to spot opportunities to reduce, reuse, recycle, and find other ways to create efficiencies.

4.      Sustainability initiatives achieve maximum benefit from involvement of their supply chain.

5.      All waste by-products are potentially new products

6.      Green initiatives foster creativity and can enhance competitive advantage.

As previously mentioned, becoming a green organization as part of a lean initiative occurs sometimes by design, and sometimes by accident.  A research study from the Sustainable Supply Chain Group at the University of Tennessee, College of Business Administration found some interesting results when evaluating how lean manufacturing, sustainability and supply chain management may at times be complementary.   The study found, among other things that: 1) Firms tend to have more sophisticated lean strategies than green strategies, and because of this awareness of ‘sustainability’ in supply chain management circles is less mature; and 2) Lean and green initiatives overlap, where projects that meet lean objectives often provide unanticipated green benefits.

Extending Lean and Green to the Supply Chain

Establishing initial goals for manufacturing efficiencies include maximizing parts, machine and material utilization, human movement and of course reducing waste. This series of continuous improvement steps offer a cornerstone for reaching both a green and efficient supply chain. But how can manufacturers work beyond the ‘four walls’ of their organizations to green their supply chain?  A green focus in supply chain management requires working with upstream suppliers and downstream customers, performing analyses of internal operations and processes, reviewing environmental considerations in the product development process, and looking at extended stewardship opportunities across the life-cycle of one or more intermediate or final products.

Lean Tools You Can Use

So far, I’ve laid a foundation for Lean Manufacturing and the intersection with supply chain management. This next section presents a couple of widely accepted practices that are used in Lean design and manufacturing, which can be modified to capture supplier network considerations.

Value-Stream Mapping

A strategic approach to mapping  environmental and lean opportunities would be to map the ‘value-stream’  of one or more products as a way to seek where the greatest waste  reduction and environmental impact reduction opportunities are. Value stream mapping arrived on the business process landscape with the emergence of Lean engineering, design and manufacturing.  A process-and systems based methodology, value stream mapping can help organizations to identify major sources of non-value added time and materials resources i.e. waste that flow into the manufacturing of a particular product or (even) service; and to develop an action (or “Kaizen”) plan to implement less wasteful practices and processes.   From an environmental perspective, practitioners can also look at processes from an environmental, health and safety point of view, focusing on processes tending to use great amounts of resource inputs and that generate waste outputs.

To illustrate what I mean, a value-stream map example (presented below) in a report issued by the U.S. EPA on Lean and the Environment depicts how supply chain vendors can interact in the production of a product and the resource waste that can result.  The areas noted in green represent interaction points with environmental, health and safety and related environmental loads associated with intermediate production steps.  Clearly the four vendor points of interaction can carry their own environmental footprints just in the trucking and distribution of raw materials and products (air and waste emissions for instance).

Typical steps in value stream mapping include:

1. Select a product or process(es)
2. Through interviews and work observations, collect data on the ‘current state’ of the value stream (inputs and outputs)
3. Using a cross functional team (CFT) of knowledgeable staff, develop a ‘current state’ value stream map; focus on identifying over consumptive or waste generating activities
4. With the CFT in place, brainstorm ideas to improve resource use, production flow, waste capture and reduction, reuse and off spec material reuse, and labor/time management
5. Create a future state’ value stream map that identifies areas, targets and key performance metrics for continual improvement.
6. Develop a implementation plan, complete with authorizes and responsibilities
7. Develop continual improvement measurement and monitoring program
8. And last but not least…get started!

 

Vendor Survey and Qualification

Manufacturers also supplement their Lean efforts by surveying their supply chain partners and  asking a series of questions designed to identify where the resource consumption and waste management opportunities may lie.  These  questions will help determine if technology, operational practices,  enhanced training and awareness or other tools can make their company  more sustainable and lead them down the path to make the decision that  best meets their business needs. These questions include but are not  limited to:

1. How can I leverage my manufacturing capabilities and processes in a way that optimizes per unit material resource consumption?
2. Can I reduce waste generation through improving material use, scrap/off spec reuse and improved equipment maintenance?
3. Can  I work collaboratively with my intermediate parts or materials  suppliers to use life cycle design practices and manufacture parts with  lowered environmental footprints?
4. How  can I encourage suppliers to increase equipment efficiency, reduce  manufacturing cycle time, reduce inventories, streamline processes or  seek quick returns on investment?
5. Can I improve my sales and operations planning to optimize production runs and reduce resource loads or generated wastes?
6. How  can I work more closely with logistics and transportation partners to  optimize shipment schedules, customer deliveries, warehousing, routing  and order fulfillment?
7. Can  I work with my customers and product designers to improve packaging to  optimize space reduce materials use and improve load management?
8. How can I collaborate more closely with customers to enable reverse logistics and profitable product reusability?
9. What  types of value-added training and development programs can I develop to  promote lean and green opportunities with my suppliers?

Lean-Green Synergies Are Not Without Challenges

The  same University of Tennessee authors who explored the intersect of  lean, green and supply chain also discussed found that some potential  conflicts with certain types of lean strategies leading to changes in  supply change management.  For instance, they noted that  “lean strategies that require just-in-time delivery of small lot sizes  require increased transportation, packaging, and handling that may  contradict a green approach. Introducing global supply chain management into the green and lean equation increases the potential conflict between the green and lean initiatives.”

So  as companies begin to implement lean and green strategies in supply  chains, especially large and complex global supply chains, manufacturers  need to explore the overlaps and synergies between quality-based lean  and environmentally based ‘green’ initiatives, and understand the  various trade-offs required to balance possible points of conflict.  If  your organization been reluctant to engage your supply chain or  implement or maintain environmental initiatives in your product  manufacturing because of the perception that you can’t afford it, then  think again.  It is more likely that you cannot afford to ignore it.
