This document outlines the steps for assessing and implementing changes to laboratory processes, systems, or products. It involves determining if the proposed change is fully verifiable and cost-effective. If not, the product or process must be redesign. It then details verifying and validating the change through testing, updating documentation, providing training, and getting final approval before implementation. The goal is to thoughtfully assess and qualify any changes to ensure outputs remain valid and documentation is updated.
