You are an Enterprise Architect working at a vehicle manufacturing company.

You are an Enterprise Architect working at a vehicle manufacturing company. The company specializes in buses and coaches. You are part of an Enterprise Architecture (EA) team that has responsibilities across multiple divisions of the company.

The company has a corporate strategy that focuses on switching to electric power for its vehicles. It has invested heavily in a new standardized design, production efforts, and major components to use across all its product range. The company has multiple manufacturing plants in North America, Europe, and Asia.

Customer demand has caused a backlog of orders because many customers want to have more environmentally friendly public transportation. There are not enough electronic components available, which is making it hard to produce products and meet customer demand. To address this issue, the company has started making the battery packs themselves and has hired new suppliers.

The company has a well-established EA practice. It uses the TOGAF Standard as the foundation for its work, including the internal EA framework. Additionally, the company uses various management frameworks such as business planning, project management, and operations management. The Chief Information Officer (CIO) and the Chief Operating Officer (COO) jointly sponsor the Enterprise Architecture program.

The EA team is working on a project to improve the process and systems to design, produce, and test the battery pack. As part of putting the new battery pack into production, changes to the assembly processes need to be made. A trial has been completed at a single location. The Chief Engineer, sponsor of the activity, and the Architecture Board have approved the plan to roll out these changes to all plants.

Preliminary Architecture Contracts have been developed that detail the work needed to put in place the new processes for each location. The company mixes internal teams with a few third-party contractors at the locations. The Chief Engineer is worried that the deployment will not be consistent and of satisfactory quality.

Refer to the scenario:

The EA team leader has asked you to review the preliminary Architecture Contracts and recommend the best approach to address the Chief Engineer's concern.
