History. Rapid application development was a response to plan-driven waterfall processes, developed in the 1970s and 1980s, such as the Structured Systems Analysis and Design Method (SSADM). One of the problems with these methods is that they were based on a traditional engineering model used to design and build things like bridges and buildings.
Software prototyping is about creating prototypes, i.e. incomplete versions of the software program being developed.. The basic principles are: [1] Prototyping is not a standalone, complete development methodology, but rather an approach to try out particular features in the context of a full methodology (such as incremental, spiral, or rapid application development (RAD)).
Waterfall model. The waterfall model is a breakdown of development activities into linear sequential phases, meaning they are passed down onto each other, where each phase depends on the deliverables of the previous one and corresponds to a specialization of tasks. [ 1] The approach is typical for certain areas of engineering design.
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.

Agile software development is an umbrella term for approaches to developing software that reflect the values and principles agreed upon by The Agile Alliance, a group of 17 software practitioners in 2001. [ 1] As documented in their Manifesto for Agile Software Development the practitioners value: [ 2] Individuals and interactions over ...
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.
Extreme programming (XP) is a software development methodology intended to improve software quality and responsiveness to changing customer requirements. As a type of agile software development, [1] [2] [3] it advocates frequent releases in short development cycles, intended to improve productivity and introduce checkpoints at which new customer requirements can be adopted.
Cap Gemini SDM, or SDM2 (System Development Methodology) is a software development method developed by the software company Pandata in the Netherlands in 1970. The method is a waterfall model divided in seven phases that have a clear start and end. Each phase delivers subproducts, called milestones.
