Iterative and incremental development is any combination of both iterative design (or iterative method) and incremental build model for development. Usage of the term began in software development , with a long-standing combination of the two terms iterative and incremental [ 1 ] having been widely suggested for large development efforts.
Evolutionary design, continuous design, evolutive design, incremental design or evolutionary architecture is directly related to any modular design application, in which components can be freely substituted to improve the design, modify performance, or change another feature at a later time.
The incremental philosophy is also used in the agile process model (see agile modeling). [2] [1]: Section 2.3.3 The Incremental model can be applied to DevOps. DevOps centers around the idea of minimizing the risk and cost of a DevOps adoption whilst building the necessary in-house skillset and momentum. [3] Characteristics of Incremental Model
The unified software development process or unified process is an iterative and incremental software development process framework. The best-known and extensively documented refinement of the unified process is the rational unified process (RUP). Other examples are OpenUP and agile unified process.
The spiral model is a risk-driven software development process model. Based on the unique risk patterns of a given project, the spiral model guides a team to adopt elements of one or more process models, such as incremental, waterfall, or evolutionary prototyping.
Software prototyping is the activity of creating prototypes of software applications, i.e., incomplete versions of the software program being developed. It is an activity that can occur in software development and is comparable to prototyping as known from other fields, such as mechanical engineering or manufacturing.
In contrast, phyletic gradualism (below), is a more gradual, continuous model of evolution – with accumulation of small incremental changes represented by slanted bars that split at branch-points, where two separate modes of life are feasible but of which, each prospers best with divergent specializations.
In this view no clear line of demarcation exists between an ancestral species and a descendant species, unless splitting occurs. Punctuated gradualism is a microevolutionary hypothesis that refers to a species that has "relative stasis over a considerable part of its total duration [and] underwent periodic, relatively rapid, morphologic change ...
