Release Management works closely with the Change Management and Configuration Management processes to ensure that the shared CMDB is kept up-to-date following changes implemented by new Releases and that the content of those releases is stored in the DSL. Hardware specifications, assembly instructions and network configurations are also stored in the DSL/CMDB.
