The software release life cycle is the process of developing, testing, and distributing a software product (e.g., an operating system ). It typically consists of several stages, such as pre-alpha, alpha, beta, and release candidate, before the final version, or "gold", is released to the public. An example of a basic software release life cycle.
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 ...
In conjunction with the various versioning schemes listed above, a system for denoting pre-release versions is generally used, as the program makes its way through the stages of the software release life cycle. Programs that are in an early stage are often called "alpha" software, after the first letter in the Greek alphabet.
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.
ISO/IEC/IEEE 12207 Systems and software engineering – Software life cycle processes is an international standard for software lifecycle processes. First introduced in 1995, it aims to be a primary standard that defines all the processes required for developing and maintaining software systems, including the outcomes and/or activities of each process.
Release engineering. Release engineering, frequently abbreviated as RE or as the clipped compound Releng, is a sub-discipline in software engineering concerned with the compilation, assembly, and delivery of source code into finished products or other software components. Associated with the software release life cycle, it was said by Boris ...
Release management. Common names of versions during different stages in software development. Release management is the process of managing, planning, scheduling and controlling a software build through different stages and environments; it includes testing and deploying software releases. [1] [2]
Diagram for a traditional software development life cycle from 1988. The numbers represent the typical cost of each phase. Software companies aim to deliver a high-quality product on time and under budget. A challenge is that software development effort estimation is often inaccurate.
