A systematic approach is needed to manage the system requirements and design methodology. Because when that service fails then your entire system can be jeopardized and end up becoming unavailable. The purpose of the System Design process is to provide sufficient detailed data and information about the system and its system elements to enable the implementation consistent with architectural entities as defined in models and views of the system architecture (ISO/IEC/IEEE 15288 [ISO 2015]). Logical design represents the abstract dataflow while physical design represents the input and output processes in the system. The process of defining the entire requirements of a system such as the architecture, modules, interface and design is called system design. A design system is a set of standards for design and code along with components that unify both practices.
