Small methods make your code easier to understand, in particular if combined with a good name. Besides, if your method is small, finding a good name is usually much easier.

Commonly applied refactorings include:

This check looks at variables that are passed out again to other methods.
If the outgoing method call has stricter type requirements than the method itself, an issue is raised.
An additional type check may prevent trouble.
