Tim has 12+ years of hands-on BI experience and covers Tableau most of all, plus Power BI, Looker, Hex, SQL and data modelling, the analytics industry, and the craft of doing the job — always tool-agnostic and honest about the trade-offs.

I co-hosted a live reaction stream alongside the Tableau Conference 2021 Devs on Stage session. We warmed up by chatting about the ideas forum, the beta programme and a few of our own feature wishes, then reacted in real time as Andrew Beers and five Tableau devs demoed what's coming to core analytics, augmented analytics, Prep, Server and Online, and Public.

## Key takeaways

- The Tableau ideas forum drives the roadmap, so voting, commenting and joining betas with detailed use cases is the realistic route to getting features built (LODs and the data model came from solving clusters of these requests).
- Visualisation extensions will let you build custom mark types and native chart templates with drag-and-drop and share them via the gallery, rather than hacking dashboards together.
- Augmented analytics is expanding with Data Change Radar and Explain the Viz, surfacing meaningful changes and contextual explanations directly in the side pane without leaving your workflow.
- Tableau Prep Conductor is gaining linked tasks, Slack notifications and parameters (including on input/output steps) to make flow orchestration far more flexible.
- Server and Online get resource monitoring baselines, per-site resource limits, Kubernetes autoscaling, connected apps for embedding and Tableau Broadcast for publishing content to public-facing sites.
