Instrument Before Scale vs Ship Then Retrofit: AI Evaluation & Observability Decision
IF an agency is about to put an LLM workflow in front of client accounts or bill it inside a retainer, THEN tracing and scoring must exist before volume arrives, because failures compound silently across multi-step agent chains. IF the workflow is still a single-prompt internal experiment with no client exposure, THEN a lightweight trace log and a weekly spot-check are enough until usage justifies a dedicated evaluation layer.

Instrument Before Scale vs Ship Then Retrofit: AI Evaluation & Observability Decision
“IF an agency is about to put an LLM workflow in front of client accounts or bill it inside a retainer, THEN tracing and scoring must exist before volume arrives, because failures compound silently across multi-step agent chains.

- Client-facing agent handles more than roughly 1,000 conversations or generations per month, where manual review stops being a real control
- The workflow chains three or more model or tool calls, so a bad output at step two surfaces as a wrong answer at step five
- Retainer language already promises accuracy, tone, or compliance outcomes that a client could audit against transcripts
- Token spend per account is climbing without a matching change in delivered output, pointing to prompt bloat or retry loops
- A voice or chat agent is live on a client's own channels, where a single bad call reaches the client's customers directly
- The AI feature is a single prompt behind an internal tool with no client-visible surface and no billing line attached
- Monthly volume sits under a few hundred calls, where a sampled human read of transcripts costs less than a platform seat
- No one on the account team can own the scoring rubric, so dashboards would be built and never checked
- The client contract has no accuracy or uptime commitment tied to the AI component
- Model choice is still changing weekly, making baseline scores stale before they are useful
