Validation introduces a vocabulary that can feel disconnected from day-to-day work. Use the video introduction to become familiar with DQ, IQ, OQ and PQ, then follow the written guides to explore how individual stages sit within the wider lifecycle.
This route connects the project view with the operational view. After the lifecycle guide, read about readiness and the validated state. The periodic review guide offers a further reading step when you want to understand how the conversation continues after initial qualification.
