There are better tools for data analysis and better presentation tools, why are firms still using this as a standard ?
Because they don’t actually need nice-to-have features.
Yes I guess all the basics can be done more easily on PPT and Excel
because companies buy office365 and ppt and excel come with it
No
No
In consulting but also no
Excel wont disappear, but Im feeling just being able to run excel wont be enough now. For instance, I use Tableau more nowadays to report to management, but I still use excel/ppt for daily, simple task. I can walk away from Tableau, but I can’t walk away from Excel and ppt.
It's too much work on company's part to change to new platforms. Just imagine the time and cost for training all the employees with new tools.
PowerBI Also comes with most 0365 subscriptions. It won't replace Excel, but what you're going to find is that a lot of the charting people were doing by hand in Excel will be done automatically when they dragged the values into PowerBI. PowerBI has much easier learning curve than Tableau
Tableau has some limitations on visualization. For eg. You are not able to create xyz dimensional charts. Additionally there are certain scaling features which are not available in Tableau. For quick predictive and prescriptive analysis excel has built in functions as well. On the other hand for large datasets one cannot use excel despite the flexibility. For eg. Excel crashes if your file size has 1 million records. On the other hand Tableau works extremely well for large datasets.
You can build xyz dimensional charts in Tableau. https://public.tableau.com/views/3DChartsinTableau/Simple3DScatterplot?:embed You also have all the same functions in Tableau as you do in Excel. You can do the same predictive and prescriptive analysis. When you need more you just use the R functions.
Maybe, the ease and learning curve
