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.

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.
Top–down approaches emphasize planning and a complete understanding of the system. It is inherent that no coding can begin until a sufficient level of detail has been reached in the design of at least some part of the system. Top–down approaches are implemented by attaching the stubs in place of the module.
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 ...
Software design usually is directed by goals for the resulting system and involves problem-solving and planning – including both high-level software architecture and low-level component and algorithm design. In terms of the waterfall development process, software design is the activity of following requirements specification and before coding ...
Systems programming, or system programming, is the activity of programming [1] computer system software.The primary distinguishing characteristic of systems programming when compared to application programming is that application programming aims to produce software which provides services to the user directly (e.g. word processor), whereas systems programming aims to produce software and ...
Program management is used in many business sectors such as business transformation, change management, construction, engineering, event planning, health care and information technology. In the defense sector, it is the preferred approach to managing large scale projects.
The IMP is a bilateral agreement between the Government and a contractor on what defines the “event-driven” program. The IMP documents the key events, accomplishments, and the evaluation "criteria" in the development, production and/or modification of a military system; moreover, the IMS provides sequential events and key decision points ...
