Adrian G. you put your finger on something most people are dancing around.
Data quality is necessary but it's not sufficient. The deeper problem is semantic coherence (AI doesn't just need clean records, it needs to understand what those records mean in the context of how that business actually operates). Deal stage definitions, qualification criteria, what a 'healthy' pipeline looks like for this team, in this cycle. That meaning lives in people's heads right now, not in the CRM schema.
