Software engineering is a field within computer science focused on designing, developing, testing, and maintaining of software applications.It involves applying engineering principles and computer programming expertise to develop software systems that meet user needs.
One component of software design is software requirements analysis (SRA). SRA is a part of the software development process that lists specifications used in software engineering. The output of the analysis is smaller problems to solve. In contrast, the design focuses on capabilities, and thus multiple designs for the same problem can exist.
Software configuration management (SCM), a.k.a. software change and configuration management (SCCM), [1] is the software engineering practice of tracking and controlling changes to a software system; part of the larger cross-disciplinary field of configuration management (CM). [2] SCM includes version control and the establishment of baselines.
Design tools are objects, media, or computer programs, which can be used to design. They may influence the process of production, expression and perception of design ideas [ 1 ] and therefore need to be applied skillfully.
Structure charts are used in structured analysis to specify the high-level design, or architecture, of a computer program. As a design tool, they aid the programmer in dividing and conquering a large software problem, that is, recursively breaking a problem down into parts that are small enough to be understood by a human brain.

Design is important to achieve high reliability, low cost, and good maintain-ability. [2] We can distinguish two types of program design phases: Architectural or high-level design; Detailed or low-level design; Structured flow charts and HIPO diagrams typify the class of software design tools and these provide a high-level overview of a program ...
