Point: A collectively-motivated group of peers can develop innovations in a distributed online environment.

Story: When Hernando Barragán created a nontechie-friendly microcontroller board for artists, designers, and architects in 2004, his thesis adviser, Massimo Banzi, liked the idea.  But Banzi wanted something simpler and cheaper for use in design class projects at the Interaction Design Institute Ivrea in Italy.  In particular, Banzi wanted a low cost, an integrated software environment, programmability via an everyday USB port, and a project supported by a community.

So Massimo Banzi, David Cuartielles, Dave Mellis, Gianluca Martino and Nicholas Zambetti created Arduino, an easy-make, easy-to-use circuit board about the size of a business card.  Anyone can use the device to create all manner of computer-controlled devices such as prototypes of products, pieces of art, or just fun hobbyist contraptions.  The team’s device was about 1/3 the price of the predecessor device and 1/3 the price of commercial products.  Best if all, the group released Arduino under Creative Commons Attribution-ShareAlike licensing, which means anyone can copy the Arduino and make the circuit board without payment or permission from the Arduino group.

The Arduino project uses open source methods to develop its hardware and software. Open source is a type of connected innovation based on the collective contribution of peer innovators to a project or product.  Open source allows free access to the internal design specification of the product such that anyone in the world can modify the design to correct a problem, improve performance, or add a new feature.  With this openness comes a cultural norm that if someone does improve the design, then they should share that improvement with the community for inclusion in the public version of the design.  Through this open process, Arduino now has 12 different models and 5 supplementary function boards.

Arduino, like other open source projects, relies heavily on connective technologies to coordinate its loose global team of project participants.  Email lists, online wikis, discussion forums, and content management systems help the project participants maintain the core product as well as developing new ideas that later become incorporated in the main products.  Arduino uses Google Code to host the project to provide a central connection point for anyone who wants the software.  People can report defects or suggest enhancements. Google’s tools help the project participants track the status, priority, and milestones of the idea.  Other tools aid collaborative problem solving.  The main Arduino discussion forum has nearly 70 thousand members and over 700 thousand posts on some 90 thousand topics.

Action:

• Determine if there’s some technology that you (and others) need more access or control over than is permitted by commercial suppliers with proprietary products
• Start an open source project to create and share the technology
• Use connection technologies to link to distant contributors and coordinate activities
• Pool innovation from across the technical and user community

Point: Additive manufacturing (also called 3D printing) technologies enable new design methods and local manufacturing by entrepreneurs.

Story:  When designing a new part to be manufactured, designers traditionally had to define the shape they wanted and then pick the material that could support that shape (based on strength, flexibility, etc.). That is, they designed the piece separate from picking the materials. For more complex products, designers had to decompose the product into semi-independent parts that were designed and manufactured separately and then assembled with screws, welding, clips, glue, and so on.  This deconstructive process risked incompatibilities between the parts, added complexity, and increased costs due to a assembly labor.

But, nature does not design in this deconstructive way. A tree trunk, limbs and leaves aren’t built separately and assembled. Rather, nature designs and grows the entire tree in a progressive, additive fashion, and largely from one material. Nature starts with a material (e.g., cellulose is the material for trees) and deploys that material in various densities, shapes, thicknesses, and modified formulations to create an integrated object.  The same basic building-block material that makes the thick rigid truck of a tree also makes the broad, flat leaves of the tree, thin flexible twigs, and hard shells of the tree’s nuts.

Additive manufacturing mimics nature (unlike traditional reductive manufacturing that removes material to make a form).  Additive manufacturing can build almost any shape that can be drawn on a computer, including hollow and contorted forms impossible to make in other ways. Specialized machines (essentially 3D printers) lay down layer after layer of material or draw with a bead of molten material to grow the part the 3D shape that was downloaded from the computer. Virtually anything that someone can imagine, draw or compute in 3D can be made with additive manufacturing.

Several competing 3D printer technologies let designers and manufacturers choose between clear resins, colored opaque thermoplastics, powered metals, and even powered ceramics.  Companies can use the technology to create prototypes, customized shapes, spare parts, and intricate parts in low quantities.  For example, Boeing used metal hybrid additive manufacturing processes and powdered metal manufacturing to create parts that reduced the weight and fuel consumption of its aircraft.

Although industrial printers like Boeing’s cost upwards of $500,000, consumer-grade printers cost only $1300.  The low price point creates a vast new opportunity for entrepreneurs to provide 3D printing services.  For example, online service company Shapeways prints any design that its customers upload, from fashion and jewelry pieces to gadgets and art. Even better, Shapeways lets is members open virtual storefronts on the site to sell their products. Some of the most popular products for sale include a PirateBay ship model, a Dymaxion world map, and a customized metal branding iron that will brand any text you want when attached to a BIC lighter. In addition, open source communities (such as MakerBot Industries, RepRap, Thingiverse) are dedicated to creating ultra-low cost printers and sharing designs for cool additive manufactured parts.

Action

• Think about how in-house 3D printing (or in-home 3-D printing) might change your business.
• Design new additive manufactured products based on shapes that would be “impossible to build” with traditional manufacturing.
• Create new business models based on products or services that support additive manufacturing or that transcend the curse of economies of scale needed by traditional manufacturing

Point: Unlike the diminishing returns of the Experience Curve, Collaboration Curves offer continuous, exponential improvement and innovation through knowledge sharing and interactions among a group of participants.

Story: Most of us have heard about the Experience Curve, which traces how a company’s rising experience in making a product leads to declining cost of that making a product.  On average, the cost declines 20-30 percent each time that a company’s experience in making that product doubles. The Experience Curve, which has been systematically studied since the 1960s, holds true across a wide range of industries.  The sad flip-side of the Experience Curve, however, is that the rate of improvement declines over time because it takes longer and longer for experience to double.  It has diminishing returns.  Can anything be done to sustain the rate of improvement? Is there another way to keep on advancing? There is: Collaboration Curves.

Collaboration — in the form of knowledge sharing and interactions among a group of participants — improves the performance of all.  Before the internet, collaboration took place primarily face to face, along with some letter-writing between participants.  For example, in the 1870s, the art movement that came to be called Impressionism arose.  A group of young painters — Claude Monet, Pierre Renoir, Camille Pissaro and others — started meeting in cafes, talking and visiting each other’s art studios. They became a collaborative group; that is, they’d share their work in progress, talk about painting techniques, experiment with colors, and help each other learn and improve.

For example, the group broke with the tradition of black shadows.  They experimented with shadows painted in purple, deep blue or a mix of other colors.  Sometimes the shadows weren’t even that dark. This was a radical idea — no one had painted shadows in a different color before, but once one of the group came upon it, others adopted it as well.  They also expanded the notions of what could be painted. The subject matter needn’t be a religious icon, mythological scene, portrait of a nobleman or an allegorical landscape — it could be something as simple as a haystack or water lilies, painted over and over at different times or day or different seasons, showing how the light and color changes with the times and seasons.  Combining their experiences accelerated the Impressionists’ innovations in color, composition, brushwork, and subject matter.

Today, these collaborative groups can extend online, enabling people to talk and share with others anywhere, any time, thereby greatly — indeed exponentially — improving the group’s capacity to produce.  In the old model, the experience of any one person (or company) grew linearly with time, which created an Experience Curve with diminishing returns.  But a collaborating group can multiply experiences by combining lessons from the successes and failures of all to create a Collaboration Curve that sustains performance improvement.  The internet, social media, and collaboration platforms greatly enhance the Collaboration Curve by increasing the number of people who can collaborate, increasing the geographic span of people who can collaborate, and increasing the access to the accumulated experience of the collaborative group.

Collaboration Curves were first identified by John Hagel, who heads consulting firm Deloitte’s Center for the Edge in Silicon Valley.  “We’re seeing the emergence of a new kind of learning curve as we scale connectivity and learning, rather than scaling efficiency,” says Hagel in his Harvard Business Review blog (coauthored with John Seely Brown and Lang Davison).  “Collaboration curves hold the potential to mobilize larger and more diverse groups of participants to innovate and create new value.”

So far, examples of internet-enabled Collaboration Curves are more anecdotal rather than rigorous because of their nascency.  But Hagel has found that collaborative environments like the popular online game World of Warcraft offer participants a way to continue improving beyond what individuals could accomplish alone.  In the business world, similar collaboration curves take place on SAP’s software developer sites, and large open source projects such as the Eclipse Foundation.  What’s exciting is that “Collaboration curves may reverse the diminishing returns dynamics of the experience curve and deliver increasing returns to performance instead,” Hagel says.  The opportunity for interactions among the many participants lets performance continue improving through the continuing contributions of ideas by other participants.

Action: Hagel found that there are three prerequisites for these online collaboration groups to work and generate the Collaboration Curve effect.

• Attract Participants: First, you need people. That’s pretty obvious, that you need people to make this work. But what’s exciting is that the people don’t all have to be talking or active all the time – it’s perfectly ok to begin by just being an observer who lurks and learns from others. Indeed, in SAP’s software developer network (SAP SDN), most participants do just that — learning by reading the discussion forums before they contribute anything themselves.
• Interact: to get better results, you start interacting with others, in discussions — in person or online — sharing experiences, making suggestions, giving feedback. The more interactions, the faster the performance improvement.
• A supportive, multi-layered environment: Supportive means friendly and online.  It also means that the technology supports the interaction through discussion boards, archives, live chats, video.  Interaction must be easy not only among peers but among all cross-cutting groups. Digital infrastructure lowers interaction costs, enabling large, diverse groups of people to share information and learn from each other, driving performance improvements for all.
