Today, open source drives technology and development, and its worldwide adoption ranges from companies with a single employee to large corporations like Microsoft and Apple. All of these organizations rely on open source to innovate, reduce development costs, and speed time to market. Recent research reports point out that open source comprises 80% to 90% of the code in a typical application. Our Open Source 360° survey provides an update on the rapid evolution of open source development, use and management. The 2017 Open Source 360° survey was conducted through Black Duck’s Center for Open Source Research & Innovation (COSRI), focusing on four important areas of open source – usage, risk, contributions and governance/policies. Our respondents include input from new players, established leaders, and influencers across vertical markets and communities. This range of respondents drives broad industry awareness and discussions of these key issues.
