That’s a really insightful overview of how data visualization consultants measure their impact! It’s great to see the focus extend beyond just aesthetics to tangible business value. 

It makes perfect sense that tracking dashboard access and visual interaction provides crucial quantitative data. However, I think the qualitative aspect of understanding how stakeholders derive those actionable insights and the specific ways visualizations improve decision-making is equally important, if not more so. Those regular feedback sessions must be invaluable for that deeper understanding and for ensuring the visualizations remain relevant and impactful in the long run.

Thanks for sharing this! It provides a clear picture of the multifaceted way data visualization consultants contribute to organizational success.
