by In this video (commented in French) I will show you how from disparate Excel files you can simply straighten your data so that you can then simply analyze them.
The Use Case is rather simple: you work in mass distribution, and you have to analyze the sales and profits of your stores (in Europe). Obviously your sales manager pointed out a big profitability problem.
Your mission is to help him analyze this problem!
But now, reality reminds you and your data is not necessarily well standardized.
Preparatory work is therefore required to be able to properly consolidate these considerate sales data from separate data sources (here Excel files).
Then, once the data has been consolidated, we can embark on a fairly simple analysis and be able to respond to the real business challenges:
- Why do I have a profitability concern?
- In which product line am I seeing the concern (or is it generalized)?
- Is it a regional, local problem?
- and above all what is the cause?
- Etc.
