Which of the following is NOT one of the four frameworks of business architecture?

The Balanced Scorecard is not considered one of the four frameworks of business architecture. It is primarily a strategic planning and management system used extensively in business and industry, government, and non-profit organizations for aligning business activities to the vision and strategy of the organization. It focuses on the organization's performance metrics and strategic objectives but does not provide a comprehensive architectural framework for business processes, capabilities, or structures.

In contrast, the Zachman Framework provides a structured way of viewing and defining an enterprise, emphasizing the relationships between different architectural aspects. TOGAF (The Open Group Architecture Framework) offers a detailed methodology and a set of supporting tools for developing an enterprise architecture initiative, while the AssistKD POPIT model focuses on a practical approach to developing solutions by taking into account the processes, organization, people, information, and technology involved in business architecture.

Thus, C is correct because the Balanced Scorecard serves a different purpose and is not categorized within the established frameworks specifically for business architecture.
