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]
SDLC was released in 1975, [3] based on work done for IBM in the early 1970s. [4] SDLC operates independently on each communications link in the network and can operate on point-to-point multipoint or loop facilities, on switched or dedicated, two-wire or four-wire circuits, and with full-duplex and half-duplex operation.

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 .
The incremental build model is a method of software development where the product is designed, implemented, and tested incrementally (a little more is added each time) until the product is finished. It involves both development and maintenance.
SDLC may refer to: Systems development life cycle or system design life cycle, which is often used in the process of software development;
The waterfall model is the earliest Systems Development Life Cycle approach used in software development. [ 3 ] The waterfall development model originated in the manufacturing and construction industries, [ citation needed ] where the highly structured physical environments meant that design changes became prohibitively expensive much sooner in ...

Modern software development processes are not restricted to the discrete ALM/SDLC steps managed by different teams using multiple tools from different locations. [citation needed] Real-time collaboration, access to the centralized data repository, cross-tool and cross-project visibility, better project monitoring and reporting are the key to developing quality software in less time.
