https://pubs.opengroup.org/architecture/togaf9-doc/arch/chap32.html 32.2.11 Change Request Purpose During implementation of an architecture, as more facts become known, it is possible that the original Architecture Definition and requirements are not suitable or are not sufficient to complete the implementation of a solution. In these circumstances, it is necessary for implementation projects to either deviate from the suggested architectural approach or to request scope extensions. Additionally, external factors - such as market factors, changes in business strategy, and new technology opportunities - may open up opportunities to extend and refine the architecture. In these circumstances, a Change Request "may be submitted in order to kick-start a further cycle of architecture work."
