Please read this scenario prior to answering the question
Your role is consultant to the Lead Architect within a company that manufactures electronic components. The company has several divisions located worldwide. After a recent study, senior management have stated a concern about business efficiency considering the company's multiple data centers and duplication of applications.
The company has a mature Enterprise Architecture (EA) practice and uses the TOGAF standard for its architecture development method. In addition to the EA program, the company has a number of management frameworks in use, including business planning, project/portfolio management, and operations management. The EA program is sponsored by the CIO.
To address the concern, a strategic architecture has been defined to improve the ability to meet customer demand and operations management. The strategic architecture includes the consolidation of multiple applications that have been operating independently within the divisions and moving them to a cloud-based solution.
Each division has completed the Architecture Definition documentation to meet its own specific operational requirements. The enterprise architects have analyzed the key corporate change attributes and implementation constraints. A consolidated gap analysis has been completed. Based on the results of the gap analysis, the architects have reviewed the requirements, dependencies and interoperability requirements needed to integrate the new environment into the company. The architects have completed the Business Transformation Readiness Assessment. Based on all these factors they have produced a risk assessment. They have also completed the draft Implementation and Migration Plan, the draft Architecture Roadmap, and the Capability Assessment deliverables.
Because of the risks posed by change from the current environment, it has been determined that a phased approach is needed to implement the target architectures. The overall implementation process is estimated to take several years.
