Parallel running is a strategy for system changeover where a new system slowly assumes the roles of the older system while both systems operate simultaneously.[1][2] This conversion takes place as the technology of the old system is outdated so a new system is needed to be installed to replace the old one.[3] After a period of time, when the system is proved to be working correctly, the old system will be removed completely and users will depend solely on the new system. The phrase parallel running can refer to the process of changing a fragment of business information technology operation to a new system or to the technique applied by the human resources departments in which the existing staff stay on board during the transition to a new staff.[4]
