modification request (MR). (1) information item that identifies and describes proposed changes(s) to a product or service (ISO/IEC/IEEE 14764:2021, Software engineering -- Software life cycle processes -- Maintenance, 3.1.8) Note: The MR can be classified as a correction or enhancement and identified as corrective, preventive, adaptive, additive, or perfective maintenance.
