  2. Software development process - Wikipedia

    en.wikipedia.org/wiki/Software_development_process

    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 .

  3. 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.

  4. V-model - Wikipedia

    en.wikipedia.org/wiki/V-Model

    In project management it is a method comparable to PRINCE2 and describes methods for project management as well as methods for system development. The V-model, while rigid in process, can be very flexible in application, especially as it pertains to the scope outside of the realm of the System Development Lifecycle normal parameters.

  5. Waterfall model - Wikipedia

    en.wikipedia.org/wiki/Waterfall_model

    The waterfall model is a breakdown of developmental activities into linear sequential phases, meaning that each phase is passed down onto each other, where each phase depends on the deliverables of the previous one and corresponds to a specialization of tasks. [1]

  6. Sequence diagram - Wikipedia

    en.wikipedia.org/wiki/Sequence_diagram

    Professionals, in developing a project, often use system sequence diagrams to illustrate how certain tasks are done between users and the system. These tasks may include repetitive, simple, or complex tasks. The purpose is to illustrate the use case in a visual format.

  7. Systems modeling - Wikipedia

    en.wikipedia.org/wiki/Systems_modeling

    In business and IT development the term "systems modeling" has multiple meanings. It can relate to: the use of model to conceptualize and construct systems; the interdisciplinary study of the use of these models

  8. Spiral model - Wikipedia

    en.wikipedia.org/wiki/Spiral_model

    In later publications, [1] Boehm describes the spiral model as a "process model generator," where choices based on a project's risks generate an appropriate process model for the project. Thus, the incremental, waterfall, prototyping, and other process models are special cases of the spiral model that fit the risk patterns of certain projects.

  9. Enterprise life cycle - Wikipedia

    en.wikipedia.org/wiki/Enterprise_life_cycle

    The enterprise life cycle is a key concept in enterprise architecture (EA), enterprise engineering [2] and systems engineering. [3] The Enterprise Architecture process is closely related to similar processes, as program management cycle or systems development life cycle, and has similar properties to those found in the product life cycle.
