Demerits of Tableau

Tableau is a powerful data visualisation tool, but it comes with its own set of demerits. Understanding these drawbacks aids in selecting the right tool and deepens clarity over What is Tableau

1) High Cost

It is a costly tool for analytics segment. Due to its high cost, it poses a challenge for small and medium-sized businesses. Although Tableau Public is free to use, it has restrictions over data privacy and sharing controls.

2) Limited Visual Customisation

Tableau offers limited design flexibility for advanced visual formats. Due to the limited options to choose from, users working with complex visual needs find customisation options limited and restrictive, 

3) No In-build Scheduling for Reports

Tableau does not provide users native report scheduling. This makes users often update dashboards and manually deliver reports. For organisations or enterprises needing automated scheduling, this can pose a limitation. 

4) Complicated Custom Formatting

It can be time-consuming to format in Tableau, especially when managing large reports. For instance, wanting to format multiple columns requires the changes to be made individually. This can result in a tedious process and does not work effective under time-sensitive deadlines. 

5) Lack of Version Control

Tableau does not provide users with strong control on version functionality. For tracking edits or managing file version, it poses a difficulty. This increases the risk of losing data and duplication of efforts when working in teams. 

6) Challenges for Preparing Data

Since, Tableau’s primary focus is on visualisation, it lacks robust built-in data preparation features. Users require external tools for certain tasks, such as transforming, segregating or cleaning data. This increases effort and is time-consuming for projects that require extensive pre-processing. 

7) Limited Collaboration

Some level of collaboration is allowed on Tableau but, its co-editing and teamwork features are limited. This affects productivity levels for large teams working together on dashboards and workbooks. 

Values in Tableau

Under Tableau, you will come across two fields, namely Measure Names and Measure Values. They are automatically created by Tableau to help users work with multiple measures flexibly. 

1) Measure Values: This represents the measure fields in your data in a centralised continuous field. This means you can drag that field into a view and it aggregates the measures it includes by their default aggregation. By placing them on rows, columns or marks shelves, you can build visualisations, showing KPIs, such as sales, profit and discounts. 

2) Measure Names: This represents the names of all measures in your data into a single discrete field. This enables you to display the measure names, such as sales or profit as part of the view. They also let you rename measure labels for bringing more clarity. This makes dashboards more readable for end-users. Also, measure Names can be filtered to show specific metrics.

Is Tableau, the Right Choice for Data Analysts?

Tableau is a widely utilised tool amongst Data Analysts for its visualisation capabilities and seamless ability to present analytics in interactive dashboards. However, modifying embedded analytics after deployment can be difficult, often requiring additional tools. This can potentially slow down workflows. 

While Tableau is excellent for reporting tasks, it provides less flexibility for startups. This is why Data Analysts need other platforms for advanced modelling before returning to Tableau. Since, it acts as a part of broader analysis stack rather than standalone solutions, costs and complexity may arise for small sized enterprises. Overall, it promotes a data-driven culture while tool switching, and workflow limitations can make analytical adoption difficult. 

Conclusion

This platform provides a powerful and accessible space for Data Visualisation and Analysis. With its intuitive design, wide range of data connection options and interactive visual analytics, Tableau empowers users to understand and present insights with simplicity. By deeply understanding What is Tableau, you can see how it helps individuals and enterprises turn complex information into meaningful decisions.
