The Architecture Board is a governance body that oversees and supports the implementation of architectures within an organization. One of its responsibilities is to conduct assessments of the maturity level of architecture discipline within the organization using frameworks such as CMMI or ACMM. This helps to identify areas for improvement and monitor progress towards achieving higher levels of maturity. Reference: https://pubs.opengroup.org/architecture/togaf9-doc/arch/chap44.html
