Leading the development of open standards for operating systems
Through its flagship Base Work Group, The Open Group leads the development of open standards for operating systems, including the UNIX®  system, POSIX® , open source operating systems such Linux® and BSD, real-time systems and network computing. The Open Group is also the specification authority for The Open Group UNIX certification program .
The Open group operates a global, vendor-neutral environment where members can network, gain relevant knowledge, grow professionally, and by participating within its Base Work Group lead the ongoing development of The Single UNIX Specification  and other standards, best practices and certifications. Our members  are shaping the future of open application development and business operations.
We welcome the participation of all who want to influence the direction and effectiveness of the Base Working Group, benefit from early access to specifications, and help us lead the development of industry standards.
