To develop an architecture that addresses the needs of all parties involved, it is crucial to first identify and define the concerns of the various stakeholders. This can be achieved by creating a stakeholder map that groups stakeholders with common concerns. Once these groups are defined, a set of views should be established to address each group's specific concerns. Architecture models can then be developed for each view to ensure all stakeholder concerns, including regulatory compliance, are appropriately addressed. This approach ensures a comprehensive and targeted response to the needs of all stakeholders, including legal and regulatory requirements.
To effectively tackle the goal of consolidating and reducing redundant procurement processes and systems, it is important to start by defining the future state, or Target Architecture, first. This approach helps in setting a clear vision and direction. You need to identify the necessary business services/functions and how they interact (Business Service/Function catalog and Business Interaction matrix), the lifecycle of key business objects (Product Lifecycle diagrams), the communication and interactions between applications (Application Communication diagrams and Application Interaction matrix), and how data is managed and associated with business functions (Data Entity/Business Function matrix and System/Data matrix). This level of foresight ensures that you are designing towards a coherent target, which then can be juxtaposed with the baseline to identify gaps and necessary transitions. Subsequently, the Baseline Architecture would be described in detail to understand the existing state and help in the smooth transition to the target state.
The best approach to address the senior management's concerns about the risks and value of the proposed architecture is to apply techniques specifically designed to assess these factors. Techniques such as the Business Transformation Readiness Assessment and the Business Value Assessment are crucial. The Business Transformation Readiness Assessment evaluates how ready the organization is for the proposed changes, identifying potential risks and areas needing more preparation. The Business Value Assessment will help to determine the expected benefits and value of the proposed architecture, ensuring that it justifies the associated risks.
The system cannot be described as conformant because one of its features, the RPC mechanism, has not been implemented according to the specification in the Architecture Definition Document. Even though the system meets most of the requirements and appears to work correctly, any feature implemented not in accordance with the specification renders the system non-conformant. The process requires strict adherence to the specified user mode threads rather than kernel mode threads. Therefore, the correct description for the system's compliance is non-conformant.
According to TOGAF 9, the initial phase of developing an architecture involves understanding and defining the business requirements and vision. Holding a series of interviews using the business scenario technique will help identify and document the characteristics of the architecture based on real business requirements. This approach ensures that the architecture vision aligns with the actual needs and concerns of the stakeholders, making it the most appropriate recommendation.
