Back after a short break: Certification, more functions, talks, Datum Podcast & Tableau Live 2021

I took April off to enjoy fatherhood and spring, and now I'm back with certification, more functions and a stack of new content.

Watch on YouTube
  • I plan my content roughly three weeks ahead, and stopping that planning in February left me with nothing scheduled by late March
  • Even with no new uploads in April, older content still pulled around 53,000 views, showing the value of evergreen tutorials
  • The Tableau Consulting Associate and Architect exams are partner-only certifications, requiring partner affiliation and access to a gated PDF, and run on the Pearson VUE system
  • Becoming a certified Tableau trainer involves a week-long course plus demonstrating your teaching to a Tableau instructor, rather than a single exam
  • I believe Tableau Online plus the browser will become the best way to use Tableau, given Salesforce's browser-first approach

This is a personal update video: Tim explains why the channel went quiet for a month and lays out what's coming next — certification content, more function tutorials, recent talks and the podcast. It's context and a look ahead rather than a technique to apply.

The Breakdown
  • Why the break happened 0:25

    Tim plans content roughly three weeks ahead of publishing, but stopped planning in February as work and life got busier, so by late March he had nothing left scheduled. He also became a dad in October and used April to enjoy fatherhood and spring rather than force out content.

  • Evergreen content still performs 1:44

    Even with zero new uploads in April, older videos on the channel still pulled around 53,000 views, a reminder that well-researched tutorials keep delivering value long after release rather than needing constant new output to sustain an audience.

  • Off-channel work adds up 2:40

    Alongside his own channel, Tim makes Tableau-related videos for other companies that appear elsewhere rather than on his channel, and this guest work also ate into the time available for new uploads.

  • Recent talks worth catching 4:31

    He gave a talk on favourite functions to a large Tableau user group audience, and a separate talk arguing that Tableau Online combined with the browser will become the best way to use Tableau, given Salesforce's browser-first direction — both being made available to watch afterwards.

  • Certification plans 7:03

    Tim is working through Tableau certifications this year to speak about them from firsthand experience: partner-only exams like the Certified Associate Consultant and Architect (which require partner affiliation and a gated syllabus PDF, and run on the Pearson VUE system), plus renewing his Certified Associate and Certified Professional exams before they lapse.

  • Becoming a certified trainer 9:40

    Separately from the exams, becoming a certified Tableau trainer requires a week-long partner-affiliated course plus demonstrating your own teaching to a Tableau instructor, rather than sitting a single test.

  • Tableau Live and the podcast 10:29

    Tableau Live runs across Europe, Asia and America over successive weeks, and Tim and Ravi are saving their livestream for the US leg. The Datum Podcast continues too, with a recent episode featuring a Tableau user researcher on user experience and how it feeds into dashboard design.

Worth Knowing
  • Tableau Consulting Associate and Architect exams are only accessible to Tableau partners, including the PDF that describes what's covered
  • Trainer accreditation isn't a single exam — it's a week-long course plus a teaching demonstration to a Tableau instructor
  • Some podcast apps (Apple Podcasts) have had distribution issues after Apple changed a sharing feature, so the Datum Podcast may not show up everywhere
Use It When

Watch this if you follow Tim's channel and want the backstory on the gap in uploads plus a heads-up on what's coming — certification breakdowns, more functions and server content.
