Program Plan Intro
Business Requirements:
- The specific business requests system should meet so as to be successful.
- The entire system development effort is driven by business requirements.
- The business requirements are gathered through investigation.
- The users identify all business needs of organization and take measurements for these needs.
- The methods to gather requirements includes:
- Conducting user interviews to determine current issues and operations.
- Surveying employees through questionnaires for discovering issues.
- Making observations to determine manner in which current operations are been performed.
- Reviewing business documents for discovering policies, reports and how information is been used in organization.
Ambiguous Business Requirements:
- An ambiguous requirement means that multiple readers may interpret the same thing in different ways.
- It may rise due to inadequate participation of end users during design and analysis phases.
- It may occur commonly in reports due to different mindset of developers and users.

You will need to implement the following: A GUI with a drawing panel. We can click in this panel, and you will capture those clicks as a Point (see java.awt.Point) in a PointCollection class (you need to build this). The points need to be represented by circles. Below the drawing panel, you will need 5 buttons: O о о ○ An input button to register your mouse to the drawing panel. A show button to paint the points in your collection on the drawing panel. A button to shift all the points to the left by 50 pixels. The x position of the points is not allowed to go below zero. Another button to shift all the points to the right 50 pixels. " The x position of the points cannot go further than the You can implement this GUI in any way you choose.
