You need to think about the design of your solution and how to go about getting it ready for programming.

Writing a program can be like having a huge problem to solve and trying to figure out the best way to solve it. Let’s start by considering some problems in the real world and figuring out how we might solve them from a design point of view. Then we’ll consider designs for problems for a computer.
