Data modeling makes the reports more flexible for modifications. As a result, the entire BI project ends up failing.
Power BI Desktop
A Power BI developer must have adequate knowledge regarding the tool. A developer will be working with the Power BI Desktop for a long time.
The Power BI Desktop seems easy to use. But a developer must know a lot about it for easy usage.
Since Power BI is an analytical tool, knowing an analytical language is a necessity. Several developers focus on learning the Data Analysis eXpression language.
But some knowledge about T-SQL, MDX, and Power Query is beneficial. Some calculations are easier using these layers.

The front end of your BI system is visualization. Users get information from this place.
Knowing the way to convey the right message is necessary. Visualization might seem easy but getting it right is difficult.
Developers must follow several principles and practices for visualization. Knowing how to execute things in Power BI is also important for visualization.
Proper visualization will help users to make informed decisions. But bad visualization will confuse the users.
