Definition: Worst-of-breed; composite noun: a strategy mixing a set of approaches, technologies or solutions so that the disadvantages add up to a disastrous combination no single item would have been able to create.
Example: Java + XML configuration files, which combines the verbosity and pain of having to create lots of meaningless code typical for statically typed programming languages with the runtime error probability of dynamic languages due to small typos, sometimes adding up to a solution that looks like an obfuscated programming contest application.
Heh. That's about the size of it. Productivity is over here.
