  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

    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 .

  4. 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] This approach is typical for certain areas of engineering design.

  5. 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.

  6. Agile software development - Wikipedia

    en.wikipedia.org/wiki/Agile_software_development

    One of the differences between agile software development methods and waterfall is the approach to quality and testing. In the waterfall model, work moves through software development life cycle (SDLC) phases—with one phase being completed before another can start—hence the testing phase is separate and follows a build phase. In agile ...

  7. Unified process - Wikipedia

    en.wikipedia.org/wiki/Unified_Process

    The final elaboration phase deliverable is a plan (including cost and schedule estimates) for the construction phase. At this point the plan should be accurate and credible since it should be based on the elaboration phase experience and since significant risk factors should have been addressed during the elaboration phase.

  8. Dynamic systems development method - Wikipedia

    en.wikipedia.org/wiki/Dynamic_systems...

    An important issue is the empowerment of the project team. This means that the team (or one or more of its members) has to possess the power and possibility to make important decisions regarding the project without having to write formal proposals to higher management, which can be very time-consuming.

  9. Systems design - Wikipedia

    en.wikipedia.org/wiki/Systems_design

    If the broader topic of product development "blends the perspective of marketing, design, and manufacturing into a single approach to product development," [5] then design is the act of taking the marketing information and creating the design of the product to be manufactured.
