I understand the trade-offs between these strategies and can recommend the most appropriate approach based on the company’s specific needs and risk tolerance.

Question 12

How do you use data visualization to communicate demand forecasts to stakeholders?
Answer:
I use data visualization tools like Tableau and Power BI to create clear and concise dashboards and reports that effectively communicate demand forecasts to stakeholders.
