  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. 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 ...

  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 architecture - Wikipedia

    en.wikipedia.org/wiki/Software_architecture

    These core architecture activities are performed iteratively and at different stages of the initial software development life-cycle, as well as over the evolution of a system. Architectural analysis is the process of understanding the environment in which a proposed system will operate and determining the requirements for the system. The input ...

  6. V-model - Wikipedia

    en.wikipedia.org/wiki/V-Model

    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.

  7. 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 ...

  8. SDLC - Wikipedia

    en.wikipedia.org/wiki/SDLC

    Systems development life cycle or system design life cycle, which is often used in the process of software development; Software development life cycle or software development process; Synchronous Data Link Control, an IBM communications protocol

  9. Conceptual model - Wikipedia

    en.wikipedia.org/wiki/Conceptual_model

    The conceptual model plays an important role in the overall system development life cycle. Figure 1 [ 6 ] below, depicts the role of the conceptual model in a typical system development scheme. It is clear that if the conceptual model is not fully developed, the execution of fundamental system properties may not be implemented properly, giving ...
