Why is the first execution of an ADM cycle considered more challenging than subsequent cycles?

The first execution of an ADM cycle is deemed more challenging primarily due to the limited architecture assets available. When an organization embarks on its initial ADM cycle, it often has not yet developed or documented a comprehensive set of architecture artifacts, models, or frameworks that are essential for guiding the process. These assets include existing architecture descriptions, standards, guidelines, and best practices, which are crucial for effective planning, decision-making, and stakeholder engagement throughout the ADM phases.

Without a foundational set of architectural work to reference, teams may struggle to establish a clear vision and direction for their architecture initiatives. This scarcity can lead to slower progress and increased difficulties in aligning stakeholders and resources effectively. As organizations progress through multiple cycles of ADM, they typically accumulate and refine these architecture assets, making subsequent cycles less challenging because there is a richer knowledge base and existing documentation to leverage.

While factors such as management unfamiliarity, governance issues, or the availability of trained practitioners can play a role in the challenges faced during an ADM cycle, the direct impact of having limited architecture assets is significant in shaping the overall success and effectiveness of the initial effort.
