Possible approaches:

Jams
Hackathons
Design Sprints
Startup Weekend - twist being - we are a distributed team, and teams start enterprises for different locations that are doing the same thing for common production
Coopetition - like FIRST Robotics
Meetup
Incentive Challenge - organize a large number of sponsors interested in a technology, with a promise to produce at low cost via preorders
Crowd Supply model - helping developers bring products to life. Electronics only.
Local Motors model - incentive challenges, results not public
HeroX model - incentive challenge; open to anyone
FIRST Robotics model - coopetitions - but add purpose to it
GrabCAD - incentive challenges - designs remain free.
L'Atelier Paysan - model of proprietary development of agriculture tools.
China Model of Innovation and Technology Transfer - develop and disseminate best practice to ALL companies
Innocentive model - you put up a prize. They help you formulate the problem statement. Can that be crowd funded in addition to Innocentive? No reqiurement of open results. [1]
OpenIDEO model - someone funds a challenge. Public design. Private enclosure of results (no requirement on result openness). [2]
Idea Connection - [3] - Open innovation for proprietary enclosure.
CAD Crowd - post challenges online. Most interesting is that people post private challenges online. [4]

OSE Narrative

What are known ways to use crowd development to achieve public-interest results? How can we innovate on this?

Ideally, a crowd-supported project would involve:

Strong Stakeholders providing sufficient development support to bring a product to market.
Ideally, an incentive prize element exists, such that contributors are incentivized.
It must likewise guarantee long-term involvement for continuity, thus a stable platform like OSE Clubs.
It must include education, so we are creating a new culture.
Prize must be sufficiently high to incentivize many people
A new industry should be built as a result - open source cordless drill industry.
Outcome is a lifetime design product - that is the main incentive.
Problem must be too difficult for a single person in order to produce a comprehensive product: it's not possible for a single person to do everything. Thus, incentive must reward collaboration.
How to reward collaboration? First, set up documentation platform, and use only open tools
Prize is divided for partial contributions
Issue: prize division may disincentivize people. Solution: non-gameable prize structure, with ample enough prize that many people are rewarded.
Issue: not easy for someone to tackle a problem that is too big. Would this incentivize ethical contributors?
Central issue is how to select for ethical contributors. May be impossible.
Ideally, we focus millions of otherwise tinkering individuals towards a common goal.
Most likely to succeed if poeple have a direct stake, if the project is not too hard. Cordless drill qualifies.
Can a cordless drill be a breakthrough?

Summary of Value Proposition

Creating a new industry by open source production engineering, distributed quality control, and access to supply chains.
Creating lifetime design as the norm
10x overall lower cost

99 Designs - We find that higher financial incentives do not translate to more effort by individual designers, but nonetheless have an impact on the quality outcome of contests by attracting a larger pool of designers - [5]
Interesting HeroX challenge - $1M student space rocket challenge. Organized by Base 11. [6]
