Targets
Designing and building devices is a lot of fun, but how do you know you are building the best device for the task? Whether you are building something simple or complex, you can take steps and use methods to be sure you are doing the best job possible. When building something new, following a design process is very helpful. A design process is the series of steps you take to be sure you are building in the best way possible. Following a design process helps when you are building with others because everyone in the group knows what to expect, and you can even divide the work.
