Benchmarking involves comparing performance metrics to external standards or peers to identify gaps and drive improvement.

Option A (Internal organizational performance): Internal performance is self-assessment, not benchmarking, which involves external comparison.

Option B (Progressive attainment of improvement): Improvement tracks progress, not benchmarking against others.

Option C (Achievement of outcomes): Outcomes reflect results, not the act of comparison.

Option D (Measurement against others): This is the correct answer. The NAHQ CPHQ study guide states, “Benchmarking is the process of measuring performance against external standards or peer organizations to identify best practices” (Domain 2).

CPHQ Objective Reference: Domain 2: Health Data Analytics, Objective 2.4, “Use benchmarking for performance comparison,” emphasizes external measurement. The NAHQ study guide notes, “Benchmarking compares metrics to others for improvement” (Domain 2).

Rationale: Benchmarking involves external comparison, aligning with CPHQ’s analytics principles.
