Software Control and Distribution

This discipline of ITIL is the management of all software Configuration Items within the organisation. It covers the management of software development, installation and support of an organisationís software products.

Software is often not regarded as a tangible asset because of its clearly intangible nature, which can result in it not being effectively controlled. There can be several versions of the same software within the organisation for example, and there can also be unlicensed and illegal copies of externally provided software.

The practice of effective Software Control & Distribution involves the creation of a Definitive Software Library (DSL), into which the master copies of all software is stored and from here its control and release is managed. The DSL consists of a physical store and a logical store. The physical store is where the master copies of all software media are stored. This tends to be software that has been provided from an external source. The logical store is the index of all software and releases, versions, etc. highlighting where the physical media can be located. The logical store may also be used for the storage of software developed within the organisation.

SC&D procedures include the management of the software Configuration Items and their distribution and implementation into a production environment. This will involve the definition of a release programme suitable for the organisation, the definition of how version control will be implemented, and the procedures surrounding how software will be built, released and audited.
