#questionFrame Diagrams
We discussed the importance of framing a problem in order to understand the problem
better and be able to develop a solution more quickly and easily. In this homework, you
are asked to use the different problem frames discussed in class to create a frame diagram
for the following software systems;
? Traffic light controller; this system switches lights between red, green, and
yellow according to timing rules, activity registered at sensors, and timing
relationships with activity at neighboring traffic lights.
? A program that tells a bus rider which buses to take to get from one location to
another, arriving by a specified time.
? An electronic email system.
Keep in mind that problem frames can be combined when solving these problems...
