Ties back another thing I brought up on the WebApps mailing list recently:
documented use cases and requirements. Quality of implementation tests
should assert the implementations fulfill the use cases a spec was
designed to meet. Effectively, this would close the circle and seed a more
iterative kind of development: use case -> requirements -> spec ->
implementation -> confirm implementation is spec compliant -> confirm
implementation meets use cases and requirements -> gather unmet or new use
cases. Repeat.
