The article introduces a new way to design systems by including both what the system should do (functional requirements) and how it should perform (non-functional requirements). This helps create better designs by considering all aspects of a system, not just its functions. The researchers developed a method to incorporate non-functional requirements into the design process, resulting in an extended design matrix that connects all requirements to the physical design of the system. This approach improves the overall design process by ensuring that both functional and non-functional aspects are taken into account.
