From the current Enterprise Architecture practice structure presented for Wanderlust GmbH, it appears that there are dedicated roles for a Chief Enterprise Architect and a Technology Architect. However, the roles of Application Architect and Business Architect are not explicitly mentioned. An Application Architect is crucial for designing and maintaining the application landscape, ensuring that it aligns with business requirements, while a Business Architect is essential for aligning IT strategy with business strategy and understanding the impact of business changes on the architecture. Their absence indicates a gap in ensuring the alignment between business processes and IT systems, as well as in defining and maintaining the application strategy.References= The roles and responsibilities within an Enterprise Architecture framework typically include both Application and Business Architects to ensure a comprehensive approach to aligning IT and business strategies.
