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.

Northwest Vista College moved to its current location in northwest San Antonio on October 17, 1998, with Mountain Laurel Hall as the first building open, and opened in October 1999 with the completion of Manzanillo Hall and Huisache Hall. Northwest Vista College had an enrollment of 2,500 students during their first full year of operation.
The V-model summarizes the main steps to be taken in conjunction with the corresponding deliverables within computerized system validation framework, or project life cycle development. It describes the activities to be performed and the results that have to be produced during product development.
The waterfall model is the earliest Systems Development Life Cycle approach used in software development. [3] When it was first adopted, there were no recognized alternatives for knowledge-based creative work.
Systems development life cycle or system design life cycle, which is often used in the process of software development; Software development life cycle or software development process; Synchronous Data Link Control, an IBM communications protocol
The main idea of the software development life cycle has been "to pursue the development of information systems in a very deliberate, structured and methodical way, requiring each stage of the life cycle––from the inception of the idea to delivery of the final system––to be carried out rigidly and sequentially" [2] within the context of ...
Instead of moving down linearly, the process steps are bent upwards after the coding phase, to form the typical V shape. The V-Model demonstrates the relationships between each phase of the development life cycle and its associated phase of testing. The horizontal and vertical axes represent time or project completeness (left-to-right) and ...
Requirements planning phase – combines elements of the system planning and systems analysis phases of the systems development life cycle (SDLC). Users, managers, and IT staff members discuss and agree on business needs, project scope, constraints, and system requirements. It ends when the team agrees on the key issues and obtains management ...
