Visualizing Data in Tableau.png

Private & Public Training

Learn how to visualize data the Flerlage way. From beginner bootcamps focused on the basics of data visualization data in Tableau, to niche master classes in advanced topics such as data modeling and complex calculations, there are upskill opportunities available for everyone, offered publicly and privately.  View the public training schedule or contact us for more information about private, customized trainings for your group.

Our beginner bootcamp, How to Visualize Data in Tableau the Flerlage Way: 101, usually consists of six half-day sessions spread over the course of two weeks. The training focuses on these key learning objectives:

  • Why we visualize data, connect to data, an intro to the canvas and pills, filters, the marks card, sheet formatting tips and tricks.

  • How to create common types of charts, dashboards and work with date fields. 

  • Deep dive into dashboards, dual-axis charts, dashboard actions, and basic dashboard design principles.

  • The power of calculated fields, including IF statements and boolean calculations, as well as parameters.

  • Data modeling concepts, Tableau's order of operations, an introduction to Tableau Cloud and Tableau Public


Fractional Data Hero Subscription

When you don't have in-house data experts or you want to turbo charge your team's capabilities without footing a six-figure bill for a deeply-experienced full-time employee, you keep a fractional data hero from Moxy on your staff, for a (you guessed it) fraction of the price.  Fractional Data Hero subscriptions range anywhere from 10 - 40 hours per month, for as a short as three months and as long as you need it.  They can be adjusted up or down, or cancelled at anytime, with a 30 - 60 day notice.  

You’re a good candidate for our Fractional Data Hero service if…

  • You consistently find it difficult or impossible to meet the data-related needs and desires of your internal stakeholders.

  • You struggle to achieve “wins” with Tableau because you can’t quite get it to do what your stakeholders want.

  • You could benefit from regular 1:1 coaching and guidance from a true expert in Tableau and data visualization. 

  • You DO NOT have an immediate or short-term need to deliver something specific. If you do, you probably need data project work instead.


Data Projects

You can hire the Flerlage twins for your deliverable-based data project work.  They can do just about everything from performance assessments and tuning, dashboard requirements gathering, design and build, to data modeling and engineering, to Tableau Cloud/Server configurations to 1:1 training, advising and coaching.  Project work is done for a fair predetermined fixed fee based on scope, complexity and velocity.

Interested in us quoting your data project? We'd love to!  Here are some initial questions you should be prepared to answer:​

  • Have you identified any key performance indicators yet? Please list them. 

  • Describe your target end user(s)? 

  • What question(s) do you wish to answer for them?

  • How do they answer these questions today?

  • How will they access these insights? And how often? 

  • What will they do with the information next?

  • Does your data include PII or PHI?

  • What is the lowest level of data granularity needed for this project?

  • How many years of historical data do you have? How many do you need?

  • How many data sources are there? Please list them.

  • Is this data widely trusted throughout your organization? 

  • From start to finish, in your own words, please describe your desired end user experience:

  • Even if it’s scribbles on a napkin, have you mocked up what this dashboard could look like?

You’re a good candidate for our Tableau Lifeline service if…

  • You have smart, capable people but inconsistently they get “stuck” and would really benefit from having quick access to a Tableau expert for assistance.

  • You DO NOT consistently find it difficult or impossible to meet the data-related needs and desires of your internal stakeholders. If you do, you should consider a Fractional Data Hero subscription instead.
