7. Development

This phase is where the system starts to be written by the software programmers. They follow the requirements specification from the design stage and start to create the new system.

The main things that take place during this phase are:

• The programmers write and test the code for the system

• A team ensure that the hardware and software required to run the new system are purchased and in place.

• A team of testers are assembled in readiness to test the new system. They start to write a test plan which details all of the tests that they will carry out.
