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
		Often, “last” decomposition done during solution
