AI Pilot Evaluation: Build a Useful Test Dataset

Recopile entradas realistas.

Seleccione ejemplos que reflejen las entradas habituales de la tarea y los casos difíciles. Incluir información incompleta y solicitudes fuera del alcance previsto. Compruebe que tiene permiso para utilizar el material y elimine datos personales innecesarios. Un conjunto conveniente de ejemplos claros puede ocultar las condiciones importantes en la operación.

Describa respuestas aceptables.

Escriba qué debe contener un resultado útil y qué lo haría inaceptable. Algunas tareas necesitan un valor correcto; otros necesitan una explicación fundamentada o una solicitud clara de más información. Pídale a la persona responsable del flujo de trabajo que revise estas expectativas antes de evaluar los resultados.

Registrar fracasos como material de aprendizaje.

Mantenga juntas la decisión de entrada, salida y revisión cuando un ejemplo falla. Busque patrones en lugar de confiar en una única impresión general. Utilice los hallazgos para ajustar los límites de la tarea o el proceso de revisión, y verifique esos cambios con el ejemplo más amplio establecido antes de expandir el piloto.

Build an evaluation set with traceable judgments

Describe the intended task and collect examples from the conditions in which it will operate. Use approved, appropriately protected material or carefully constructed fictional examples. Include common inputs, uncommon but important cases and requests outside the task boundary. Record why each example belongs in the set.

Write an expected result or a review rubric before testing. Have reviewers compare a small selection and resolve disagreements about correctness. Keep development examples separate from the evaluation used to make a continuation decision. When the prompt, model or source material changes, record the version and rerun relevant checks. Preserve individual failures instead of reporting only an overall score that can conceal a serious error.

An evaluation case and result log

A spreadsheet can be enough for an early pilot if permissions and versioning are appropriate. Use stable identifiers so a result can be traced to the original case.

• Case ID and category: common task, ambiguous input, exceptional case or out-of-scope request.
• Input and context: approved material, relevant source version and information available to the system.
• Expected behaviour: required facts, permitted uncertainty and outcomes that must be rejected.
• Review rubric: dimensions such as factual accuracy, completeness and suitability for the task.
• Observed output: system version, result, reviewer judgment and explanation of any disagreement.
• Disposition: correction, additional investigation, acceptance or a reason to stop the pilot.

Do not let the demonstration become the test

If the team repeatedly adjusts a system against the same examples, those examples no longer provide an independent view of performance. Keep a separate evaluation set and describe its limits.

Avoid forcing subjective outputs into a single unexplained pass/fail score. Review disagreement and significant failure categories separately. Do not treat an absent error in a small sample as proof that the error cannot occur. The final decision should reflect both the evidence and the consequences of getting a result wrong.

How many evaluation examples are enough?

There is no universal number for every task. Begin with coverage of meaningful input types and failure cases, then expand where results are uncertain. Consider the variety of work and consequences of errors rather than choosing a sample size solely because it is convenient.

ILLUSTRATIVE PLANNING EXAMPLE

Example: evaluating document summaries

Choose documents representing the lengths, structures and language the team expects to handle. Include a document with conflicting dates and one with an important exception. Write down the facts a useful summary must preserve and the errors that make it unacceptable. Remove confidential details before sharing examples outside the approved environment.

Keep a separate evaluation set and record reviewer judgments consistently. A few impressive summaries are not enough to establish suitability for the full workflow.
