Six elements of software development plan to solve the problem of the definition of an overall software design, including the understanding of user requirements and reality software product design, from three aspects of technical, economic and social factors to study and demonstrate the feasibility of the software project software design, preparation of feasibility studies, to explore solutions to the problem of software design industry, and the resources available (such as computer hardware, software, labor, etc.) costs, benefits and development progress can be made to estimate. Develop implementation plans to complete the development tasks. This phase of work is based on the requirements of the requirements specification, design, architecture, build the appropriate software systems and interfaces relations break down the entire system into a number of sub-systems or modules, defined subsystems or modules, specific to each subsystem design definition, writing software outline design and detailed design specifications, database or data structure design specifications, assembly and testing program. In the initial stage of any software or system development must fully grasp the user needs to be able to follow the system development process which functions should be implemented, in what size and what limits to set the priority to be positioned. Systems engineers will thus complete the final design, based on the subsequent program development, system functionality and performance and limitations described in a definition.
