The company has been very successful and has been buying companies around the world. This has led to a growing number of manufacturing divisions in various locations with a complex supply chain. The top management recently expressed concerns about the company's effectiveness because of its multiple data centers and duplicate applications. The EA team has been working on a project to solve this issue. An analysis shows that supply chain issues have led to not enough products being produced to meet all the customer demand. A strategic architecture has been defined to help meet customer demand and manage the supply chain more effectively. The strategic architecture involves combining different Enterprise Resource Planning (ERP) applications that are currently used separately in the company's production sites. Each division has finished the Architecture Definition documentation to address their own specific manufacturing needs. The Enterprise Architects have agreed an overall strategy for the migration. They have defined a set of work packages that address the gaps found. They have defined the intermediate architectural states between the Baseline and Target architecture to add a new ERP environment into the company. Because of the risks posed by this change from the current environment, the architects have recommended that a phased approach should be taken to implement the target architecture with several stages of change. They have created a draft roadmap with the implementation process estimated to take over two years. The company has an established Enterprise Architecture (EA) practice and follows the TOGAF Architecture Development Method. The company also uses various management frameworks such as business planning, project/portfolio management, and operations management. The EA program is sponsored by the Chief Information Officer (CIO).
