正解:C
The correct answer is C . IIBA explains that business analysis creates value by enabling change and improving outcomes across the organization, and this includes continuous evaluation and alignment of solutions with organizational goals. Monitoring and evaluating outcomes helps determine whether the change is delivering the intended value and where adjustments are needed to improve performance.
Option A is incorrect because documentation may support the organization, but documentation alone is not how business analysis primarily enhances organizational performance. Business analysis is focused on enabling value and better outcomes, not just producing artifacts.
Option B is incorrect because writing technology briefs is not a core description of how business analysis improves performance. It may be a communication activity in some contexts, but it does not represent the main performance-enhancing role of business analysis.
Option D is incorrect because business analysis does not narrow its focus only to implementation. IIBA frames business analysis as spanning strategy, initiative, and delivery contexts, with performance improvement requiring broader and ongoing evaluation.
