There is a second, rarer refactoring game. 
Identify indirection that isn't paying for itself and take it out. 
Often this takes the form of intermediate methods that used to serve a purpose but no longer do. 
Or it could be a component that you expected to be shared or polymorphic but turned out to be used in only one place. 
When you find parasitic indirection, take it out. 

Again, you will have a more valuable program, 
not because there is more of one of the four qualities listed earlier but 
because it costs less indirection to get the same amount from the qualities.
