Defining & Tracking Your LLM Evaluation Metrics

Description

This capability focuses on identifying, applying, and maintaining the right set of metrics to evaluate Large Language Models (LLMs) for specific enterprise use cases. It includes defining success criteria, aligning on constraints, and tracking quantitative and qualitative indicators throughout the evaluation process.

Why it's Important

Without clearly defined and consistently tracked metrics, LLM evaluations are prone to bias, inefficiency, and misalignment. Teams may rely on irrelevant benchmarks, overlook important constraints, or reach conclusions that don’t reflect real-world performance. Defining and tracking the right evaluation metrics ensures teams compare models fairly, choose solutions that meet business needs, and build confidence in GenAI decisions. It also provides a foundation for repeatable and scalable evaluation practices across teams.

Why it's Challenging @ Scale

  • Misaligned success criteria across teams: Different groups may define model performance in conflicting ways, leading to inconsistent results.
  • Overuse of generic benchmarks: Standard metrics like accuracy or perplexity are often applied without regard to business context or task relevance.
  • Insufficient support for qualitative metrics: Many teams struggle to capture usability, interpretability, or trust-related outcomes.
  • Gaps in data instrumentation: Without strong data foundations, teams may lack visibility into key evaluation signals.
  • No feedback loop for refining metrics: Without post-evaluation analysis, metric sets become outdated or disconnected from real outcomes.

Complexity

High: Maturing this capability requires cross-functional agreement on what to measure, access to the right tools and data, and repeatable processes for applying and refining metrics at scale.
