Chapter 25, Problem 25.8E
Explanation of Solution
Change request form will probably justify a change. The key benefits of using a change request form are as follows:
- It will provide the ability to monitor and approve change requests from any single location.
- It coordinates changes impact throughout the project plans.
- It maintains the integrity of the performance measurement baselines – all approved changes must be reflected in the...

- Java Graphics (Bonus In this lab, we'll be practicing what we learned about GUIs, and Mouse events. 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.
