4. Implement changes. The change management process model requires all the parties involved to keep
records of all relevant information on change cases to build a case base for future use. Unlike previous stages,
no major decision is expected during the change implementation stage. An operational system is needed to

coordinated well. Everything recorded is linked with each other and to the change cases as well in order to
facilitate the change analysis procedures afterwards.
