In the 28th session of Chandoo.org podcast, let’s figure out how to express business rules & logic to Excel.
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
How would you go about modeling these in Excel?
That is our topic for this podcast session.
In this podcast, you will learn
- The challenge of modeling business logic & rules in Excel
- My struggles with such formulas in early days
- 4 features of Excel that can help you with this.
- Example business rules & how to write formulas
