In the online pharmacy's 'order medication' task, what type of rule is the test for customer age and quantity considered?

The test for customer age and quantity in the online pharmacy's 'order medication' task is classified as a business rule - constraint because it imposes specific limitations that must be adhered to in order to comply with laws and regulations regarding medication dispensing. Constraints are foundational criteria that govern how processes operate and ensure that certain conditions are met before a transaction can proceed. In this context, verifying customer age ensures compliance with legal age restrictions for purchasing certain medications, while limiting the quantity addresses concerns about safe and responsible use.

Operational guidance, on the other hand, generally refers to procedures or steps that inform how to carry out a task but do not enforce mandatory limits. Thus, while guidance can aid in performing tasks effectively, it does not impose the same stringent compliance requirements as a constraint, which is necessary for legal or safety reasons in this scenario.
