KINDNESS RHoK is a rapidly growing global community initiative involving over 6,000 innovators in more than 35 countries who make the world a better place by developing practical, open source technology solutions to some of the most complex challenges facing humanity. RHoK is a mass collaboration—a movement that intelligently engages masses of people in collective action toward specific outcomes. Gathering people from diverse backgrounds and organizations, RHoK leverages their creative potential for software-based solutions the world urgently needs. RHoK is backed by Google, Microsoft, Yahoo!, HP, NASA and The World Bank as its Core Partners and DiUS as a Regional Partner for Australia, as well as a host of over 225 local partners around the world from the corporate, government, civil society and academic sectors. The year-round operations of RHoK are managed by mass- collaboration specialists, SecondMuse. Random Hacks of Kindness represents a novel approach to identifying and solving challenges for social impact. This process begins with defining local and global problems, prototyping solutions at internationally coordinated hackathons, and supporting the development and deployment of high- potential projects. Through RHoK, local experts, NGOs and community members identify problems which are then refined and curated by subject matter experts with field knowledge working in collaboration with technologists. Twice yearly, RHoK facilitates global hackathon events as a way to kickstart the projects that can be rapidly prototyped during a weekend, and then developed by the community throughout the year. The cost of prototyping solutions in a hackathon format is very low, yet the value of the resulting projects, partnerships and knowledge is significant—particularly for social impact organizations that struggle to achieve their goals with limited resources and technical support. RHoK projects tackle problems in a range of subject areas from international development to civic activism. Promising prototypes built at the hackathons are further developed through a process of incubation and implementation at the local level. RHoK is unique in its international reach, efficient use of resources and wide-range of subject matter areas covered with solutions that create a sustainable and measurable impact. The collaborative structure of RHoK also enables rapid response to new challenges that arise in this young and quickly evolving space. RHoK continually strives to measure its programmatic value, even through rapid growth and expansion. The technology solutions themselves, and their resulting impact, as well as the value of the thousands of professional hours donated, are only a part of RHoK’s value. Equally compelling, though perhaps more elusive, are the benefits that result from the building of a global community of individual and organizational actors collaborating for the betterment of the world. RHoK has become a platform for bringing people together to realize a purpose--from partnerships built among companies who are otherwise competitors, to collaborations undertaken between the non-profit and technology sectors. Through that platform RHoK has seen international collaboration and knowledge sharing take place, new models of peer-to-peer skills building and experiential learning, leadership capacities developed, jobs created, public data utilized for public good, and increased awareness among technical professionals of the broad array of human development challenges that their specialized skills can impact. RHoK is nothing less than an opportunity for motivated individuals to collaborate on expanding their own capacity to have an impact on the world, and in doing so to engage with people from the grassroots on up to the highest levels of governments, corporations, and other institutions. This report details the methodology, goals and impact that have made RHoK successful, and replicable in any community - including yours.
