Why is this requirement confusing? 

When looking at a requirement for a system behaviour that includes system performance, my understanding is that it is non-functional requirement, however, in some ways it is also considered functional requirement. I will share an example below

 

"The system must send an confirmation email after 5 seconds from the User Registration" This is a Non-Functional Requirement, because it involves performance that is measured by time

 

"The password expires after 60 days of inactivity" How come this is a functional requirement when it relates to the System Performance? If it deemed a business rule then the previous example is also a business rule, or am I missing something?

Many thanks for the advice

Re: Why is this requirement confusing? 

My logic - If any task can be done better, it becomes non functional.

A confirmation email to be sent - Functional requirement

Confirmation email to be sent in 5 seconds - Non functional requirement

Password to be expired - Functional requirement. 

Password expired after 60 days of inactivity is policy (or business rule).

Re: Why is this requirement confusing? 

Hello. According to me:

1-Business rules are a kind of requirement. From them, we can derive system (product) requirements.

“Password expires after 60 days of inactivity” is a business rule. A derived system requirement could be: “the system shall reset the user’s password after 60 days of inactivity”.

2-Complete (functional) system requirements should be stated as follow:

[If Trigger-Event(s) occur [during Precondition(s),]] the system shall [not] perform Response-Action(s) [resulting in Postcondition(s) [within Quality-Threshold(s)]] (see D. Firesmith).

3-The distinction functional requirement vs non-functional requirement doesn’t really matter when elaborating the requirements. She makes sense later when designing and testing the system.

Hope having helped you,

Gildas

Re: Why is this requirement confusing? 

From my point of view, they are both business rules therefore Functional Requirements.
