  2. Spiral model - Wikipedia

    en.wikipedia.org/wiki/Spiral_model

    In authentic spiral process cycles, these decisions are made by minimizing overall risk. Considering requirements specification as an example, the project should precisely specify those features where risk is reduced through precise specification (e.g., interfaces between hardware and software, interfaces between prime and sub-contractors).

  3. Software evolution - Wikipedia

    en.wikipedia.org/wiki/Software_evolution

    The evolution speed is a function of the feedback loop structure and other characteristics of the global system. Process simulation techniques, such as system dynamics can be useful in understanding and managing such global process. Software evolution is not likely to be Darwinian, Lamarckian or Baldwinian, but an important phenomenon on its ...

  4. Lehman's laws of software evolution - Wikipedia

    en.wikipedia.org/wiki/Lehman's_laws_of_software...

    In software engineering, the laws of software evolution refer to a series of laws that Lehman and Belady formulated starting in 1974 with respect to software evolution. [1] [2] The laws describe a balance between forces driving new developments on one hand, and forces that slow down progress on the other hand. Over the past decades the laws ...

  5. Software visualization - Wikipedia

    en.wikipedia.org/wiki/Software_visualization

    Software visualization [1] [2] or software visualisation refers to the visualization of information of and related to software systems—either the architecture of its source code or metrics of their runtime behavior—and their development process by means of static, interactive or animated 2-D or 3-D [3] visual representations of their structure, [4] execution, [5] behavior, [6] and evolution.

  6. Function model - Wikipedia

    en.wikipedia.org/wiki/Function_model

    In systems engineering, software engineering, and computer science, a function model or functional model is a structured representation of the functions (activities, actions, processes, operations) within the modeled system or subject area. [1] Example of a function model of the process of "Maintain Reparable Spares" in IDEF0 notation.

  7. V-model (software development) - Wikipedia

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

    In software development, the V-model [2] represents a development process that may be considered an extension of the waterfall model and is an example of the more general V-model. Instead of moving down linearly, the process steps are bent upwards after the coding phase, to form the typical V shape.

  9. Flowchart - Wikipedia

    en.wikipedia.org/wiki/Flowchart

    A flowchart is a type of diagram that represents a workflow or process. A flowchart can also be defined as a diagrammatic representation of an algorithm, a step-by-step approach to solving a task. The flowchart shows the steps as boxes of various kinds, and their order by connecting the boxes with arrows.
