P_SAPEA_2023 Exam Dumps : SAP Certified Professional - SAP Enterprise Architect

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.

When evaluating the SAP Enterprise Architecture Framework for Wanderlust GmbH, you should proceed with the following steps:

I evaluate both the SAP EA Methodology and TOGAF ADM. I recommend the approach that fits best Wanderlust’s requirements. This step is necessary because the SAP EA Methodology is based on TOGAF ADM, but extends it with additional elements and guidance specific to SAP solutions and customers4. Therefore, you need to compare and contrast the two methodologies and assess which one suits Wanderlust’s needs better. For example, you may consider factors such as the complexity, scope, scale, and objectives of Wanderlust’s architecture projects, as well as the availability of resources, skills, and tools.

I check whether the SAP Reference Business Architecture and Reference Solution Architecture Content can help to either define the scope of the architecture work or describe a target architecture structure. If they do, I suggest to use the Reference Architecture Content of SAP. This step is beneficial because the SAP Reference Business Architecture and Reference Solution Architecture Content provide a set of pre-defined architectures that cover common business scenarios and solution domains for SAP customers5. Therefore, you can use them as a starting point or a reference point for your architecture work, as they can help you to define the scope, requirements, capabilities, components, patterns, and best practices for your architecture solutions.
