The document describes the enterprise architecture definition approach for a large pharmaceutical company undergoing transformation. The approach included assessing the "as-is" state, defining principles and policies, and creating "to-be" architecture views for business, information, applications, and integration. Key deliverables were TO-BE processes, information models, application catalogues, services catalogue, and transition views to guide implementation projects and address challenges such as scope management and stakeholder alignment. The tailored enterprise architecture definition helped bridge the strategy to implementation of the company's transformation.
