Analysis Phase

Study the current system

Write requirements report

Design Phase

Identify potential solutions

During the 'Identify potential solutions' activity of the Design Phase, the project team needs to find out how the system will fulfill requirements that were identified in the last analysis phase. There might be more than one way to solve these problems. With this, it is possible that there will be a more more effective, less costly, or less complex solution to others. This means that it is not wise to go with the first solution you come up with to solve your problem(s). This is where the project team should think of several different potential hardware and software solutions by brainstorming and researching.
