Question

how the sdlc or system development life cycle works?

Answer 1

Systems Development Life Cycle, or SDLC, is defined by the United States Department of Justice as a software development process, although it is also a distinct process independent of software or other Information Technology considerations. It is used by a systems analyst to develop an information system, including requirements, validation, training, and user ownership through investigation, analysis, design, implementation, and maintenance.

SDLC is also known as information systems development or application development. An SDLC should result in a high quality system that meets or exceeds customer expectations, within time and cost estimates, works effectively and efficiently in the current and planned information technology infrastructure, and is cheap to maintain and cost-effective to enhance.

Answer 2

System development life cycle stages:

1.Eliciting ( finding the clients/user requirement through different means.

2.Planning ( what you will input(add) and what you want as the output of your work)

3.Drafting (checking is your planning is correct)

4.Producing(designing)

5.Testing = checking the system

6.updating (maintance) 80 % of time is spent maintaining the system.

Updating can be making system changes

Updating can be done to add new features and / or expand the system

New legislation(rules) or may requires system changes

Implementation= planing, designing and testing
