Software engineering is a branch of both computer science and engineering focused on designing, developing, testing, and maintaining software applications. It involves applying engineering principles and computer programming expertise to develop software systems that meet user needs.
How best to create high quality software is a separate and controversial problem covering software design principles, so-called "best practices" for writing code, as well as broader management issues such as optimal team size, process, how best to deliver software on time and as quickly as possible, work-place "culture", hiring practices, and ...
Software engineering the application of a systematic, disciplined, quantifiable approach to the development, operation, and maintenance of software and the study of these approaches; that is, the application of engineering and computer science to software. Cryptographic engineering Cryptographic Engineering is the discipline of using ...
In software engineering, a software development process or software development life cycle (SDLC) is a process of planning and managing software development. It typically involves dividing software development work into smaller, parallel, or sequential steps or sub-processes to improve design and/or product management .
The process is part of software engineering which also includes organizational management, project management, configuration management and other aspects. [1] Software development involves many skills and job specializations including programming, testing, documentation, graphic design, user support, marketing, and fundraising.
QFD house of quality for enterprise product development processes. The term systems engineering can be traced back to Bell Telephone Laboratories in the 1940s. [1] The need to identify and manipulate the properties of a system as a whole, which in complex engineering projects may greatly differ from the sum of the parts' properties, motivated various industries, especially those developing ...
The V-model is a graphical representation of a systems development lifecycle.It is used to produce rigorous development lifecycle models and project management models. The V-model falls into three broad categories, the German V-Modell, a general testing model, and the US government standard.
Software engineering ethics is a large field. In some ways it began as an unrealistic attempt to define bugs as unethical. [citation needed] More recently it has been defined as the application of both computer science and engineering philosophy, principles, and practices to the design and development of software systems.
