The Open Group is a not-for-profit company with over 15 years experience of developing standards and interoperable products.

Why are standards important?

Standards allow applications to be developed independent of any particular operating system implementation. They allow a stable foundation on which application development can occur and application investment can be preserved. The UNIX specification is one such application platform.

The Open Group has been the custodian of the specification for the UNIX system and the trademark since 1993. The effort that led to this transfer was the catalyst for all vendors to make their systems conform to this single definition, a goal that had been elusive in previous harmonization efforts. Today all the major vendors support the Single UNIX Specification and have registered product.
