What-if simulations are useful not just for countries opening up again. They can be handy for simple enterprise decisions, in these uncertain times. "What's the impact of sales and inflows on your cash flows and margins?" "When you're short of worker capacity, which products should you produce, or which customers to serve?" "How will the phase-wise opening impact your helpdesk call volumes and IT incidents?" No, most of these simulations don't need fancy tools or heavy analytics. They can be done on excel. Business rule-based approaches are good starting points. Where are you using what-if simulations? #datascience #analytics #whatifmodels #businessanalytics #covid19 #recession
