An application that addresses a diverse set of stakeholders and multiple levels of user groups is more complicated and technically challenging than an application that is focused on a niche homogenous user base. The Non functional requirements (NFRs) of such applications are hence very critical and important. Defining the NFRs independent of the functional requirements has many benefits. It leads to a focused effort on NFRs, a robust architectural framework, engineering excellence and consistency. The NFR stack when implemented as a loosely coupled framework, could also become a common stack for multiple applications / products, resulting in significant reduction in cost of development, support and maintenance (TCO).
