At the heart of every piece of enterprise software is its business logic, the code that analyzes inputs and creates appropriate outputs. It’s how we turn the steps of a business process into code, adding logic at every step in a workflow. That way we only need to write necessary code and we can avoid complexity.
Not all business logic is set in stone. Some processes, especially those that are key to a business’s finances are often driven by external rules and regulations that can change at short notice. For example, you might be calculating sales tax as part of an e-commerce service when government policies force a sudden change in the rate or how those rates are applied.
