What's the best way to catch missing error scenarios in product requirements?

The best way to catch missing error scenarios in product requirements is to run a validation checklist focused on early issue detection. This process identifies vague requirements, missing scenarios, and oversized features.

Why does my PRD validation fail on feature sizing and dependency ordering?

PRD validation fails on feature sizing and dependency ordering when the document lacks comprehensive checklist coverage. It evaluates feature completeness, test coverage, and RLM optimization to ensure proper structural elements.

When do I need to run a PRD validation check?
