Evaluation Stacks vs Manual Review

Evaluation Stacks vs Manual Review

Evaluation tooling is valuable when it makes decisions safer and review faster. It is less valuable when it produces scores nobody trusts or workflows nobody follows.

Manual review remains strong when

• The team is still small and the workflow surface is limited.
• Quality expectations are nuanced enough that human judgment is the main bottleneck.
• The cost of added tooling would exceed the operational benefit.

Structured evaluation stacks become stronger when

• Prompt or model changes happen frequently.
• Multiple teams need shared evidence and regression discipline.
• The workflow has expensive failure modes that require repeatable checks.
