Supply Chain Analytics in Tableau or Power BI
๐ Background
Test your BI skills on a real-world dataset focusing on supply chain analytics. As the main data analyst for Just In Time, you will help solve key shipment and inventory management challenges, analyze supply chain inefficiencies, and create insightful dashboards to inform business stakeholders about potential problems and propose structural business improvements.
Be creative and make use of your full skillset! Use this Workspace to prepare your data, import the tables into your local Tableau or Power BI instance, and share your insights below.
The end goal will be a (set of) interactive dashboards that demonstrate clear insights for Just In Time.

๐ช Challenge
Using either Tableau or Power BI, create an interactive dashboard to summarize your research. Things to consider:
- Use this Workspace to prepare your data (optional).
- Some ideas to get you started: visualize how shipments are delayed, by country, product, and over time. Analyze products by their supply versus demand ratio. Rank products by over or understock. Don't feel limited by these, you're encouraged to use your skills to consolidate as much information as possible.
- Create a screenshot of your (main) Tableau or Power BI dashboard, and paste that into the designated field.
- Summarize your findings in an executive summary.
