You have been assigned the role of Lead Enterprise Architect for a manufacturing firm that specializes in musical instruments.

In the last ten years, the firm has expanded into European markets and will soon establish a market in Latin America. A future expansion into the Asia Pacific region is also planned.
The firm is organized into several business units that each focus on manufacturing particular families of instruments such as brass, woodwind, and percussion.

The Enterprise Architecture (EA) program within the firm has been functioning for several years. It has made significant progress in consolidating the technology portfolio and establishing key standards. The CIO and the COO are pint sponsors of the EA program.

The EA process framework is well coordinated with the PMO, Systems Development, and Operations functions.

One of the goals of this reorganization is to improve the ability of Marketing to collect more meaningful market analytics that will enable each sector to better address market needs with effective marketing campaigns and global product presence.
A Request for Architecture Work to address the goals of the reorganization has been approved. As the architecture team commences its work, the CIO has expressed concerns about whether the firm will be able to adapt to the proposed architecture and how to manage the associated risks.
