A couple years ago, politicians in Poland wanted to do a quick change to the country's universal pension system. The change had to be quick to score some kind of political win. They wrote the new law and went on with quickly pushing it through parliament. To their surprise, sometime along the legislative process , the contractor responsible for maintenance and changes in the pension system informed them that they can indeed implement the change - by June next year. The politicians learned that, in the mordern computerized world, just passing a new law does not change how the state bureucracy operates.
