Software licensing has grown very complex because of technology-specific license rules – e.g., processor, core, server, node, and authorized user. Software owners are employing the software audit as a significant revenue opportunity. Software audits can be very expensive so take them seriously. Software audits are legal, not purely technical or IT matters, because the outcome is determined by the language of the license agreement. The contract language contained in a license agreement frequently is subject to different interpretations and positions. Get the legal department involved early and keep the legal department in the middle of any communications with the licensor, working closely with the IT and procurement departments.
