This report is based primarily on a workshop involving 42 people from academia and industry.
The goal of the workshop was to share systematic knowledge about the components, characteristics,
practices, and transformative impact of effective VOs; identify topics for future research that will
inform the ongoing design, development, and analysis of VOs for science and engineering research
and education; and create a new cross-disciplinary VO research community to conduct research across
a range of important topics. A subsequent workshop brought together more than 200 practitioners and
VO researchers to discuss how to build effective virtual organizations, and some of the material from
that workshop is represented here.

The author describes in this paper the creation and operation of the Open Science Grid (OSG [1]), a distributed shared cyberinfrastructure driven by the milestones of a diverse group of research communities. The effort is fundamentally collaborative, with domain scientists, computer scientists and technology specialists and providers from more than 70 U.S. universities, national laboratories and organizations providing resources, tools and expertise. The evolving OSG facility provides computing and storage resources for particle and nuclear physics, gravitational wave experiments, digital astronomy, molecular genomics, nanoscience and applied mathematics.
