> Apply Evaluation before deployment with clear evidence.

## Understand Evaluation before deployment

For **Evaluation before deployment**, begin with the problem it solves. Identify the inputs, constraints, and observable outcome before choosing an implementation.

## See the workflow

Use this path while practising **Evaluation before deployment**: understand, act, verify, and improve.
