Select one (1) system that you familiar with (For example, A cloud phone system for organization, an artificial immune system and the Patient monitoring systems) and describe the process/stages of the system by using the waterfall model. The process/stages as per below: 1. Requirements analysis and definition The systems services, constraints, and goals are established by consultation with system users. They are then defined in detail and serve as a system specification. 2. System and software design The system design process allocates the requirements to either hardware or software systems by establishing an overall system architecture. Software design involves identifying and describing the fundamental software system abstractions and their relationships. 3. System testing During this stage, the software design is realized as a set of programs units. Unit testing involves verifying that each unit meets its specification. 4. System Integration The individual program units or programs are integrated and tested as a complete system to ensure that the software requirements have been met. After testing, the software system is delivered to the customer. 5. Operation and maintenance Normally this is the longest life cycle phase. The system is installed and put into practical use. Maintenance involves correcting which were not discovered in earlier stages of the life cycle, improving the implementation of system units and enhancing the systems services as new requirements are discovered
