Documents the specific library names containing the application source code and executable components. If multiple staging environments are used, the libraries are separated by Development, QC testing, User Acceptance testing, Pre-production Staging and Production. All development and support analysts need to know where specific system components, data, test routines/scripts, files and databases are stored via library name or physical storage device address or identity.
