Rewriting poor Design Patterns by good Design Patterns Position Paper

[GHJV94] proposed a number of design patterns that offer good solutions for recurring design situations. Along with the good solutions they also discuss naiv solutions to these design situations and argue why such naiv solutions should be replaced by a sound design pattern. Our position is that this exactly describes the task of OO reengineering: find patterns within a legacy OO program that show a poor solution for a (recurring) problem and replace this poor solution by a sound solution offered by the corresponding design pattern.
