Which systems life cycle phase acquires, develops, and tests new hardware and software?

The systems life cycle phase that acquires, develops, and tests new hardware and software is known as the Development Phase.

During this phase, the actual creation of the system takes place, which includes:

1. Acquisition of Resources: Gathering the necessary materials, including hardware components and software tools required to build the system.
2. Development of Software: This involves writing code, designing user interfaces, and creating databases.
3. Testing New Systems: Comprehensive testing is performed to ensure that both hardware and software function together as intended. This may include unit testing, integration testing, system testing, and user acceptance testing.

It is crucial for organizations to thoroughly test the system in this phase to identify and resolve any defects or issues before the system goes live, ensuring efficiency and reliability in its performance once deployed.
