“Barriers to Eco‐innovation: Overcoming the Corporate Culture Resistance for Change and Innovation”
by Alexandre Gobbo Fernandes
Slide #2: How to build an organizational structure and culture that embraces innovation? Success depends of the company as a whole: strategy, technology, information and knowledge resources, process, people, structure and culture. Model and transform an “organization's environment” to build an innovative company prepared to be resilient, adaptable and with fast response. Slide #3: Eco‐innovation managers need special capabilities to lead business through uncertainties and risks of innovation. For the complex and dynamic business environment, leaders and firms realized the need of change and engaged on it. Business people lack on tools that complement their business skills to take into account a complex web of factors: competitors, technology, legal, etc. in an unfamiliar and uncharted territory: INNOVATION Slide #4: To achieve Eco‐innovation leadership and competitiveness, creativity behavior is vital issue. The individuals behaving creatively, with the right management tools and within a supportive organizational environmental, are a fundamental part to build a successful innovative company. Slide #5: Leadership is the capacity of understand uncertainties, face challenges and take the risks. First thing, how do we get to innovation? Second thing, we need to be creative. But in which way? Focusing on the targets and the results (that is design attitude).
Byrd, J. & Brown, P. L. (2003). The Innovation Equation: Building Creativity and Risk Taking in Your Organization. Ed. Jossey‐Bass/Pfeiffer.
Slide #6: Individual behavior is the core of Organization Outcomes This chart is based on the “interactionist model of organizational creativity” and shows a simplified model of creative behavior into a social context, within an organization. 1) An innovative firm wants to have creative outcomes to the environment. 2) The functions and processes inside the firm are made by work groups, that can have different behaviors. 3) The behavior of a work group is mainly influenced by the individuals behavior within this group. So, individuals that have creative behavior are needed so companies can have creative outcomes.
Adapted from: Woodman, R.W., Sawyer, J.E. & Griffin, R.W. (1993). Toward a Theory of Organizational
Creativity. The Academy of Management Review, Vol. 18, No. 2. Woodman & Schoenfeldt (1989). Interactionist model of organizational creativity.
Slide #7: In order to be creative, people need to be able to view things in new ways or from a different perspective. Creativity is the ability to generate ideas and alternatives to solve problems and communicate with others. To be creative is important, not only the number of alternatives but the uniqueness of those alternatives. Creativity requires fundamental qualities of thinking, such as: flexibility, ambiguity, unpredictability and enjoy the unknown.
Robert E Franken (1999). From Human Motivation. Thomson Brooks/Cole 3rd ed., 1999. Illustration: Central Design Studio. http://www.co‐d.net
Slide #8: Creativity needs a design attitude to focus on innovative results for long‐lasting organizational betterments. But, creativity itself is not going to bring the organizational, product or process innovations required. To put creativity into practice to serve the organization goals, you must have a design attitude to educate the management practices. The figure shows how a mind of a design thinker manager works. The thinking process is an iteration between diverging: looking for all the ways to solve your problem and converging: focusing on a specific solution.
Osterwalder, A. & Pigneur, Y. (2010). Business Model Generation. John Wiley & Sons Inc.,2010. Illustration: IDEO LLC. www.ideo.com
Slide #9: How to (re) design organizational elements to engage the company top management on innovation. “Most business processes are about making choices from a set of existing alternatives. In order to innovate, we have to have new alternatives and new solutions to problems, and that is what design can do.” Tim Brown, CEO of IDEO (Companies who extend design thinking across the value chain include Apple, Starbucks, LEGO, Sony, Virgin, Whirlpool and Xerox.) Slide #10: A firm’s ability to exploit and explore innovations is highly impacted by its organizational design. Companies have to be able to both: exploit efficiencies of incremental innovations as explore opportunities of radical innovation. The chart shows how different can organizational culture types be, depending on the nature of the business. Adhocracy fits for companies that need more flexibility and have an external focus, the case of innovative and knowledge business such as consultancies, marketing, R&D, design, architecture etc. Sometimes a company has more than one configuration. J. T. Hage (1999). Organizational Innovation and Organizational Change. Annual Review of Sociology,

Based on the Competing Values Framework. Addison‐Wesley Longman, Inc.
Slide #11: The capacity of organizational learning, problem‐solving and creativity is a result of its configuration of functions & processes. So, because of the the environment of innovation is complex and very dynamic, the best configuration for innovation firms and departments is Adhocracy. Adhocracy is a configuration that enable innovation processes to work with: mutual adjustment, low formalization, low centralization, high social specialization and organic structure. Carroll, G. R. (1984). Organizational Ecology. Annual Review of Sociology, Vol. 10 (1984). Published by
Annual Reviews. Illustration from : Cesar Minoru Harada, [email protected] ‐ www.cesarharada.com ‐ CC
Slide #12: Business managers need a methodology that uses design tools to complement skills. “Managing by Design” concept is a new emerging methodology. Since 2009 there is a MBA curriculum that integrates: Design attitudes, Design thinking and Design skills (Weatherhead School of Management, University of Cleveland, Ohio) Not just design companies uses design tools, but many others e.g.: Telenor ‐ Customers Insigths (telecom products); BMW, Nestle, Swatch ‐ Ideation (breakthrough products); HP ‐ Visual Thinking (creative process); Microsoft, Nokia ‐ Story telling (potential future tangible);

Slide #13: “Business innovates or they fail to survive. What will differ for life beyond the Industrial Age bubble will be what inspires that innovations.' Peter Senge The design way of thinking can be applied to: systems, situations, procedures, protocols, and innovation. You can design the way you: lead, manage, create and innovate. Xerox was doing all these things twenty years ago, way before these ideas were that clear.
Senge, P., Smith, B., Kruschwitz, N., Laur, J. & Schley, S. (2010). The Necessary Revolution. p. 285. Nicolas Brealey Publishing.
Slide #14: Eco‐innovation is all about inspiration in nature. The Case Xerox Late 90's Xerox released a innovative Document Center family (DC 260), that: yielded 200 patents, inspired imitators, won national design awards and were pivotal for Xerox finances. They realized they were designing and manufacturing copiers to spend JUST a few years with customers BUT million of years in landfills. They started from a clean sheet, a great creative work starting from understanding constraints ‐ the nature constraints. They developed the specifications and invert the processes to deliver a different product.
Senge, P., Smith, B., Kruschwitz, N., Laur, J. & Schley, S. (2010). The Necessary Revolution. p. 285. Nicolas Brealey Publishing.
Slide #15: Eco‐innovation is all about taking‐risks. The Case Xerox The team of Xerox had to bring up an innovation capable to maintain the company's solvency, that was passing throught extreme financial stresses. It was a “bet‐your‐company” type of situation. The engineers felt they were not working on just typical constraints from management. They started to re‐create the copying business for the digital age. The design objective was to be able to reuse and/or remanufacture all parts of the copiers. They though big and beyond. They had a vision “Zero to landfill, for the sake of our children”
Senge, P., Smith, B., Kruschwitz, N., Laur, J. & Schley, S. (2010). The Necessary Revolution. p. 285. Nicolas Brealey Publishing.
Slide #16: Eco‐innovation is all about profiting in a triple bottom line: The Case Xerox After: six years of development, 800 professionals involved, a completely change of the business model paradigm of the company, the results were astonishing: DC 260 is produced in “Waste free” plants, inspiring suppliers to engage in the “zero to landfill” vision, 97% of the new machine is recyclable and 93% is remanufacturable. At least 1.9 billion pounds of waste was avoided and $ 3,6 billion were saved on manufacturing costs.

WHY ARE PRODUCERS TAKING BACK CARPETS?“Carpet Take‐Back: EPR American Style”
Factors driving the carpet take‐back initiatives in the US:
Profit ‐ i.e. replace virgin materials with lower cost recycled nylon;
Marketing ‐ i.e. increasing “eco market share” in a competitive industry;
Demand for recycled content ‐ i.e. Provide recycled nylon for use in “eco automobile parts”;
Preempting legislation ‐ i.e. take‐back legislation, landfill bans at the state level, and procurement guidelines that require take‐backs;
Inteface Inc. advocacy ‐ highly publicized efforts of leasing and closed‐loop recycling of carpet manufacturer.

How Interface Innovates with Suppliers to Create Sustainability Solutions
“A Systematic Approach to Supplier Partnership
We developed a systematic approach to determine which suppliers had the capability and the passion to partner with us in pursuit of our sustainability goal.
In many cases, we were asking our suppliers to completely change the way they manufactured their product, ranging from the raw materials they used to the type of energy they powered their plants with.”

“Product Service Business Model”
By Alexandre G. Fernandes
This presentation aims to explain the product‐service business model implications and impact
for the success of sustainable business based on Eco‐innovation. The goal is to get the attention for
the product‐service business model as a key factor for the Eco‐business, focusing on the close‐loop
systems through the use of collaboration networks and structured information flows. To create the
slides for the presentation, it is intended to blend the three layers of analysis showed below:
A) The fundamentals will focus on the “close loop” technical system from the Cradle to Cradle
framework, also supported by concepts of “move to service‐flow business model” from the four key
major economical shifts to engage the Natural Capitalism and the “Integrative Project Model”
concept from the Design & Sustainability report from Green Blue + Summit Foundation. (2 min.)
B) To induce insights for strategic thinking on the product‐service applications in the “real
business” will be made an analysis of the drives of values and performance through sustainability
diagram from the CSR Europe report, to show what are the principal concerns of any company and
how it could be applied for a eco‐business. (3min.)
C) Real business will give the best vision of what has already been done and what are the
main concerns and challenges for the application of the product service business model. The paper
from Fishbein, B. K.“Carpet Take‐Back: EPR American Style” has some good practical examples of the
challenges with focus on the pioneering practices of the industry of carpet in USA and in the article
“How Interface Innovates with Suppliers to Create Sustainability Solutions” signed by Eric Nelson, vice
president of Interface Americas, will give us a good overview on the management stile of this leading
company. (4 min.)

“Natural Capital refers to the earth’s natural resources and the ecological systems that provide vital
life‐support services to society and all living things. These services are of immense economic value;
some are literally priceless, since they have no known substitutes. Yet current business practices
typically fail to take into account the value of these assets—which is rising with their scarcity. The
journey to natural capitalism involves four major shifts in business practices, all vitally interlinked:
1) Radically increase the productivity of natural resources,
2) Shift to biologically inspired production models and materials,
3) Reinvest in natural capital and
4) Move to a “service‐and‐flow” business model: The business model of traditional
manufacturing rests on the sale of goods. In the new model, value is instead delivered as a
continuous flow of services — such as providing illumination rather than selling light bulbs. This aligns
the interests of providers and customers in ways that reward them for resource productivity.”

The Drives of Values and Performance through Sustainability Diagram
CSR Europe Report
Driver of value Some examples of driving performance through sustainability.
Grow sales faster Innovative products to meet sustainability needs. Attract customers by corporate responsibility stance.
Increase operating profit margin Better workforce efficiency by treating people better – attract better people, more training, less absenteeism, lower staff turnover. Efficiencies due to energy and waste management.
Reduce cash tax rate Possibly take advantage of incentives.
Fewer fixed assets Improve efficiencies.
Less working capital Reduced waste leading to reduced inventory. Better supply chain practices as companies work in co‐ordination.
Increase the period for which the organization has a competitive advantage
Increase the period brand equity in the sustainable company. Compliance leads to legitimacy which extends the ‘license’’ to operate.
Lower cost of capital Investors perceive lower risk in companies that are compliant with ‘best practice’ governance regulations.
“A key aspect of the technological competency to develop and adopt eco‐innovations and use
technological opportunities offered by the market depends on the creation of relationships and the
formation of strategic alliances with actors across the production chain (costumers or suppliers) and
