Anarchy
Creative experimentation, whether it's in assembly lines or in software, is not precluded by any standard *in a development context*.
However, an intelligent manager does not place anything *into production* without careful consideration of its overall effects, which involves planning and documentation.
To do otherwise is little more than anarchy, which will quickly become unmanageable, unmaintainable, and eventually inconsistent and unprofitable.
The key is to know when/where "creative experimentation" applies vs when/where carefully considered/documented implementation should take place.
