In systems engineering, information systems and software engineering, the systems development life cycle ( SDLC ), also referred to as the application development life cycle, is a process for planning, creating, testing, and deploying an information system. [ 1] The SDLC concept applies to a range of hardware and software configurations, as a ...
The history of software engineering begins around the 1960s. Writing software has evolved into a profession concerned with how best to maximize the quality of software and of how to create it. Quality can refer to how maintainable software is, to its stability, speed, usability, testability, readability, size, cost, security, and number of ...
Systems engineering uses a host of tools that include modeling and simulation, requirements analysis, and scheduling to manage complexity. Systems engineering is an interdisciplinary field of engineering and engineering management that focuses on how to design, integrate, and manage complex systems over their life cycles.

History of computing. more timelines ... Computer operating systems (OSes) provide a set of functions needed and used by most application programs on a computer, and the links needed to control and synchronize computer hardware. On the first computers, with no operating system, every program needed the full hardware specification to run ...
Software development. In software engineering, a software development process or software development life cycle 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.
Timeline of computing presents events in the history of computing organized by year and grouped into six topic areas: predictions and concepts, first use and inventions, hardware systems and processors, operating systems, programming languages, and new application areas. Detailed computing timelines: before 1950, 1950–1979, 1980–1989, 1990 ...
Dynamic systems development method ( DSDM) is an agile project delivery framework, initially used as a software development method. [ 1][ 2] First released in 1994, DSDM originally sought to provide some discipline to the rapid application development (RAD) method. [ 3] In later versions the DSDM Agile Project Framework was revised and became a ...
