The TOGAF Architecture Development Method (ADM) is visually represented as a cycle with Requirements Management at its core. This central placement signifies that it is a continuous, dynamic process that underpins all phases of architecture development. It ensures that every stage of the ADM is aligned with business needs and that requirements are consistently managed from initial identification through to implementation and governance. Stakeholder engagement is intrinsically linked to this, as stakeholders are the primary source of requirements, concerns, and business goals that the architecture must address. Therefore, both are central to successful architecture development.

A. This is only a subset of the purpose. Requirements Management covers the entire lifecycle of requirements, not just processing changes to them.

B. Requirements are not captured only once. They are identified, elaborated, and refined iteratively throughout all relevant phases of the ADM cycle.

C. Requirements Management is a continuous process that interacts with all ADM phases; it is not a discrete step within each phase.
