The company has been very successful and has made acquisitions around the world. It has led to a growing number of manufacturing divisions in many locations with a complex supply chain. Senior management recently expressed concerns about the company's effectiveness because of its multiple data centers and duplicate applications.

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 defined a set of work packages that address the gaps found. They have noted the value produced, work needed, and dependencies between work packages to achieve a target architecture for adding 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. The entire implementation process is estimated to take over two years. The company has an established Enterprise Architecture (EA) practice and follows the TOGAF Architecture Development Method.
