Answer 1

6 phases of system development life cycle are-

1-Preliminary examination: Begin with a starter investigation, propose elective arrangements, portray expenses and benefits, and present a fundamental arrangement with proposals.

2-Systems examination, necessities definition: Define venture objectives into characterized capacities and tasks of the planned application. This includes the way toward social occasion and deciphering realities, diagnosing issues, and prescribing enhancements to the system. Task objectives will be additionally supported by investigation of end-client data needs and the evacuation of any irregularities and inadequacy in these necessities.

3-System examination

First the IT system proposition is examined. During this progression, consider every single current need that would be influenced and how they ought to be taken care of. Before any system arranging is done, a possibility study ought to be led to decide whether making another or improved system is a practical arrangement.
