Decision Foundry’s Lijin Dev Keloth shares how to build a dashboard using Tableau’s Extension SDK.
In our race to secure the latest technology, are we losing sight of the customer? When we create a dashboard by dragging and dropping widgets on to a screen, are we making sure the people who will use it can access what they need? Research suggests that many businesses struggle with user adoption, which ends in attrition and migration to yet another reporting system. To overcome this issue, it’s crucial to develop visually appealing Tableau dashboards that are easy to learn and engaging. With Tableau’s native features, it’s possible to create quality dashboards that are easy on the eyes. But can we take it a step further and create a dashboard that’s as user-friendly as a webpage?
Tableau Webinar Episode 1: Decision Foundry’s Lijin Dev Keloth shares how to build a dashboard using the Extension SDK (Software Development Kit). We covered the basics of Tableau Extensions, the different types available, and how they make your Tableau ecosystem that much better. We also explored what an Extension Dashboard (Accelerators using Extension) is, who needs it, and how it solves common problems. Finally, we addressed the question of whether Extension Dashboards can replace current Tableau dashboards.

Common Questions
Mastering Tableau is Decision Foundry's webinar and learning series covering Tableau from fundamentals to advanced data visualization. Episodes are hosted by our Tableau Zen Masters and Iron Vizards — typically 30–60 minutes each — covering specific Tableau capabilities like extensions, performance tuning, design pedagogy, data UX, and more.
Tableau fundamentals (datasource design, calculations, dashboards); extensions and Data UX patterns; performance optimisation (extract design, calculation refactoring); design pedagogy (information hierarchy, user research, audience-specific design); Tableau Pulse AI activation; embedded analytics; and integration with the broader Salesforce / data stack.
New and existing Tableau users wanting to deepen their expertise. Particularly valuable for dashboard developers, data analysts, and design-conscious data professionals who want to learn from Zen Masters and Iron Vizards — not generic Tableau training.
No. Tableau's official certifications (Desktop Specialist, Certified Associate) are the industry-recognised credentials. Our series complements them — many episodes cover topics that the official curriculum doesn't address (Data UX design, advanced extensions, performance tuning at scale). For exam prep specifically, our paid training program includes certification-prep curriculum.
Multiple Tableau Zen Masters and Iron Vizards on staff — among the highest concentration of Tableau elite credentials at any partner. We pioneered the "Data UX" practice (designing dashboards as user experiences, not data dumps). Our award-winning dashboard library is publicly available, and our customer work has been featured in Tableau's official conferences.
Tableau is core to our practice. Sharing expertise via open content demonstrates depth and contributes to the global Tableau community. Combine the series with our paid training or Tableau consulting for deeper engagement.
