  2. Systems development life cycle - Wikipedia

    en.wikipedia.org/wiki/Systems_development_life_cycle

    A systems development life cycle is composed of distinct work phases that are used by systems engineers and systems developers to deliver information systems.Like anything that is manufactured on an assembly line, an SDLC aims to produce high-quality systems that meet or exceed expectations, based on requirements, by delivering systems within scheduled time frames and cost estimates. [3]

  3. V-model - Wikipedia

    en.wikipedia.org/wiki/V-Model

    The V-model summarizes the main steps to be taken in conjunction with the corresponding deliverables within computerized system validation framework, or project life cycle development. It describes the activities to be performed and the results that have to be produced during product development.

  4. ISO/IEC 15288 - Wikipedia

    en.wikipedia.org/wiki/ISO/IEC_15288

    The ISO/IEC 15288 Systems and software engineering — System life cycle processes is a technical standard in systems engineering which covers processes and lifecycle stages, developed by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC).

  5. Software development process - Wikipedia

    en.wikipedia.org/wiki/Software_development_process

    The main idea of the software development life cycle has been "to pursue the development of information systems in a very deliberate, structured and methodical way, requiring each stage of the life cycle––from the inception of the idea to delivery of the final system––to be carried out rigidly and sequentially" [2] within the context of ...

  6. ISO/IEC 12207 - Wikipedia

    en.wikipedia.org/wiki/ISO/IEC_12207

    ISO/IEC/IEEE 12207 Systems and software engineering – Software life cycle processes [1] 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.

  7. V-model (software development) - Wikipedia

    en.wikipedia.org/wiki/V-Model_(software_development)

    The V-Model demonstrates the relationships between each phase of the development life cycle and its associated phase of testing. The horizontal and vertical axes represent time or project completeness (left-to-right) and level of abstraction (coarsest-grain abstraction uppermost), respectively.

  8. Waterfall model - Wikipedia

    en.wikipedia.org/wiki/Waterfall_model

    The waterfall model is the earliest Systems Development Life Cycle approach used in software development. [ 3 ] The waterfall development model originated in the manufacturing and construction industries, [ citation needed ] where the highly structured physical environments meant that design changes became prohibitively expensive much sooner in ...

  9. Systems engineering - Wikipedia

    en.wikipedia.org/wiki/Systems_engineering

    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 ...
