The correct answer is C. Perform a root cause analysis. When an existing solution is underperforming, the BA must perform a root cause analysis to identify the underlying reason before making recommendations.

Why each option

When an existing solution is underperforming, the BA must perform a root cause analysis to identify the underlying reason before making recommendations.

ADevelop new performance metrics

Developing new performance metrics does not explain why performance has already degraded and does not address the problem that exists today.

BComplete a decision analysis

Decision analysis is used to evaluate and choose among multiple options under uncertainty, not to diagnose the cause of an existing performance problem.

CPerform a root cause analysisCorrect

Root Cause Analysis is a structured technique used to identify the fundamental cause of a problem rather than treating its symptoms. Because the performance degradation correlates with increased transaction volume, the BA must determine whether the root cause is an architectural limitation, a resource constraint, or a design flaw before recommending a fix. Without identifying the actual cause, any recommendations risk being ineffective or misdirected.

DRe-analyze the current performance metrics

Re-analyzing existing metrics may reveal the extent of the degradation but does not identify the underlying reason it is occurring.
