 Moreover, a model-centric approach is prohibitively time-intensive to keep updated and leaves too much room for error as changes to the architecture occur unchecked and isolated in the heads of small groups of architecture specialists.Instead, the EAM effort has to bring the highly distributed knowledge of all experts to the table and allow every participant to provide such knowledge and input in the terms that best fit the experience and expectations of the contributing stakeholders.Successful enterprise architecture programs are approached from a management perspective as opposed to a modeling perspective.
