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.

QFD house of quality for enterprise product development processes. The term systems engineering can be traced back to Bell Telephone Laboratories in the 1940s. [1] The need to identify and manipulate the properties of a system as a whole, which in complex engineering projects may greatly differ from the sum of the parts' properties, motivated various industries, especially those developing ...
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.
Dynamic systems development method (DSDM) is an agile project delivery framework, initially used as a software development method. [ 1 ] [ 2 ] First released in 1994, DSDM originally sought to provide some discipline to the rapid application development (RAD) method. [ 3 ]
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.
Thus in product development, systems design involves the process of defining and developing systems, such as interfaces and data, for an electronic control system to satisfy specified requirements. Systems design could be seen as the application of systems theory to product development .
This is a list of approaches, styles, methodologies, and philosophies in software development and engineering. It also contains programming paradigms, software development methodologies, software development processes, and single practices, principles, and laws.
