Where Tableau shines
Tableau is strong for exploration and visual storytelling. Users can click a region, filter a period or drill into a segment and see everything update. It is a good fit for analysts who want flexible views and for audiences who value polished visuals.
Our approach
We start with a clear question and sketch the dashboard layout, then prepare the data and build views with calculated fields that match your definitions of key measures. Level-of-detail expressions let us compute figures at the right grain, for example customer-level values inside a regional summary. We test filters and actions so users cannot reach confusing combinations.
Public versus private data
Tableau Public is free but publishes content openly, so it should be used only for data that can be public. For confidential data we recommend a private deployment on Tableau Cloud or Server, or a different tool. We advise on this at the start.
Alternatives
If your organisation uses Microsoft tools, Power BI may be a better fit; for lightweight needs, Excel dashboards can be enough. For well-organised sources, see data modelling and integration.

Frequently asked questions
Do I need a Tableau licence?
Tableau Desktop and Cloud need licences; Tableau Public is free but fully public. We help you choose.
Can Tableau use my Excel data?
Yes, and also databases, CSV, Google Sheets and many cloud services.
What are LOD expressions?
Calculations that control the level of detail at which a measure is computed, independent of the view.
Can I embed the dashboard on my website?
Often yes, with Tableau Public for public data or with embedding options for private deployments.
Is Tableau better than Power BI?
Each has strengths. We recommend based on your data, budget and existing tools.
Can you train my team?
We provide a walkthrough and documentation so your team can maintain the workbook.
