What are non-functional quantitative requirements? I got the following question for homework but I am confused on what is being asked. I'm not looking for you to give me the answers I am just wondering what non-functional quantitative requirements are? I thought non-functional requirements, such as as usability, maintainability, etc., were qualitative? > Specify and comment on seven non-functional quantitative requirements for an e-commerce application. You should choose one sub-characteristic from each of the main characteristics [from ISO 9126].

Quantative requirements are defined in terms of numerical values.

ISO9126 is a software quality model, which has the following characteristics:

* Functionality
* Reliability
* Usability
* Efficiency
* Maintainability
* Portability



Few examples:

**Efficiency.**

System must be able to handle 10,000 concurrent users.

**Usability**

System must be available in two languages: English and French.

I can't believe they make people pay for this: <

Wish my homework was that interesting at a time. Good luck.
