What is in this session?

What good are spreadsheets if they can’t solve business problems?

But we all struggle when it comes to modeling real world business conditions in Excel. For example, if you have below business rule to decide how much discount to offer a customer,

If the customer bought 3 or more times previously and offer 15% discount
If the customer bought 1 or 2 times previously AND customer’s age is >40, offer 10% discount
If the customer visited our New York store between 6PM-9PM offer 5% discount
Else no discount
