The DCC Alliance (DCCA) was an industry association designed to promote a common subset of the Debian Linux operating system that multiple companies within the consortium could distribute.
The DCC Alliance was formed whilst Murdock was CEO of Progeny Linux Systems, and he remained the key spokesperson for the consortium during their visible existence.
The stated intention was to assemble a standards-based core of Debian, provide a predictable release cycle and Linux Standards Base compliance.
