According to the SAP Enterprise Architecture Framework, the best approach to addressing a business challenge through an architecture vision would be:

Identify the stakeholders, their concerns, and business requirements to create a comprehensive stakeholder map. This step is crucial to ensure that the architecture will address the needs of all parties involved.

Confirm and elaborate on business goals, business drivers, and constraints to clearly understand the objectives and limitations that the architecture must operate within.

Evaluate the enterprise capabilities and assess the readiness for business transformation to determine if the organization has the necessary resources, processes, and technology to support the new business model and achieve the strategic goals.

This method ensures that the architecture vision is aligned with the business strategy, that stakeholder needs are adequately addressed, and that the company is prepared for the changes that will come with the new business model.
