While some of the NFRs categories we introduce may initially seem irrelevant to your work environment or project, it’s important to consider each one before dismissing anything. For example, a brand-new fleet of ATMs being deployed around the globe may have very different Operational Environments. Some will be installed as standalone units in shopping malls, while others may face the exterior directly through the walls of branches. These ATMs could be located in northern Canada or downtown Cairo. By analyzing one type of NFR, other important factors such as Internationalization and Security may also come to light.
