I. Using test data to evaluate and assess the solution.

1. Volume Data

Test data is intended to ensure that the system functions as expected while processing huge amounts of data.

Response times are assessed, and the data might help determine the system's best hardware.

2. Simulated data

Aims to evaluate the system's functionality under a simulated operational environment.

3. Live data

The real information that the operating system processes

Live testing makes sure that it functions properly in actual circumstances.

II. Verifying the initial system requirements have been met

The requirements report and requirements prototype initially described the requirements. Participants and users provided feedback. Trying things out and utilising the instructions

III. The operating manual is tested to make sure that any adjustments are made as needed.

The operating handbook must be used to inform participants about and assist them with the new system's primary functions.

IV. Examining the impact on participants, the environment, and information system users

The individuals who will be impacted by the information system must benefit from it.

Areas to take into account include

Ergonomics: The system's working environment must be user-friendly and safe.

Individual and data privacy must be protected.

V. Modifying system components when issues have been found

Routine upkeep and upgrades

Maintains the system's compliance with regulations and enhances functionality.

Upkeep of software and hardware

Repairing flaws

Upgrading as required

Create backups

Safeguarding against viruses

Every alteration results in a fresh start for the SDLC.

After any modifications, the documentation is updated to match the most recent working system.
