2&3. Solve or Decompose
For
each step, solve it or decompose it further, i.e. apply same
technique
•Most
“top level” steps can’t be brained out, and need further decomposition
•“Top
level” steps often seem huge, too
•The
technique allows one to concentrate on only one problem at a time
•As before, focus on inputs, outputs, process to transform
inputs into outputs
