What does a business architect coordinate with business stakeholders?

The role of a business architect is pivotal in aligning business strategies with technology solutions, making option A the most suitable answer. A business architect coordinates with business stakeholders to design the architecture that facilitates the reuse of application assets. This involves understanding the business needs, evaluating existing resources, and ensuring that the architecture supports efficient processes and enhances operational capabilities. By focusing on reusability, the business architect can help streamline development, reduce costs, and improve consistency across applications, ultimately leading to a more agile and adaptable business environment.

The other options highlight functions that may be related to project management or operations but do not directly align with the core responsibilities of a business architect. Conducting market research is typically more aligned with a marketing role or a business analyst's tasks, while supervising development teams and managing project budgets are more in the realm of project managers or technical leaders. Thus, the emphasis on coordinating architecture design with stakeholders underscores the business architect's unique position in bridging the gap between business requirements and IT solutions.
