Suggestions have been made on how these can be adapted to apply to design change management. A construction design change management (CDCM) model is proposed as a possible solution, enabling practitioners to make an informed decision regarding the true impact of proposed changes.The CDCM model concept incorporates a design structure matrix (DSM) and process map generation to create a checklist of rework.
