System life cycle - also known as the system development life cycle, is a model that describes a system's existence from conception to disposal.

STAGES OF THE SYSTEM LIFE CYCLE

PLANNING- The first stage of the system development life cycle, where the project is planned out.

Analysis - the stage where the needs of the company are determined, and how to meet them.

Design - the stage where the architecture, components, and data for the system are defined.

Development - the stage where the system is created.

Testing - is a crucial phase that ensures the system is free of errors and functions correctly under various conditions.

Implementation - the stage where the system is deployed.

Maintenance - is an ongoing phase where the system is monitored, maintained, and updated as needed.
