The way we learn about using most machines is not adequate when we are
trying to learn how to use a computer. Problem solving ability is a major
factor in success with computers. The STAIR technique for problem solving
is a good way to summarize the problem solving process. Problem solving is
a fluid process. It may be necessary to apply the process to a large
problem, to break that problem into many smaller problems, and apply the
same process to the smaller problems.
